+title: "Agents"
+description: ""
+---
+
+Agents combine a system prompt, model preference, tool permissions, and display
+metadata into a reusable assistant profile. OpenCode includes agents for common
+workflows, and you can override them or add your own in configuration or
+Markdown files.
+
+## Built-in agents
+
+| Agent | Mode | Purpose |
+| --- | --- | --- |
+| **Build** (`build`) | `primary` | Default coding agent. Tools are allowed by default, sensitive environment-file reads ask for approval, and access outside the workspace asks for approval. |
+| **Plan** (`plan`) | `primary` | Planning agent. File edits are denied except for OpenCode plan files. Shell commands are not generally denied. |
+| **General** (`general`) | `subagent` | General-purpose research and multi-step work. It has broad tool access but cannot launch more subagents. |
+| **Explore** (`explore`) | `subagent` | Read-only code and web exploration using `read`, `glob`, `grep`, `webfetch`, and `websearch`. |
+
+OpenCode also has hidden `compaction`, `title`, and `summary` system agents.
+They run internal maintenance tasks and are not selectable. There is no built-in
+`scout` agent in V2.
+
+You can override a built-in agent with an entry of the same ID. Set
+`disabled: true` to remove one.
+
+## Default agent
+
+Set the primary agent used when a session has not selected one:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "default_agent": "reviewer"
+}
+```
+
+The configured agent must exist, must not have `mode: "subagent"`, and must not
+be hidden. If it is unavailable, OpenCode falls back to `build`, then to the
+first visible agent that can run as a primary agent. This selection does not
+rewrite the agent already stored on an existing session.
+
+## Modes
+
+An agent's `mode` controls where it can run:
+
+| Mode | Behavior |
+| --- | --- |
+| `primary` | Can be selected as the main agent for a session. It cannot be launched as a subagent. |
+| `subagent` | Can run in a child session through the `subagent` tool, but cannot be selected as the main agent. |
+| `all` | Can be used either way. This is the default for a custom agent when `mode` is omitted. |
+
+In the TUI, press <kbd>Tab</kbd> and <kbd>Shift</kbd>+<kbd>Tab</kbd> to cycle
+through visible primary and `all` agents, or use `/agents` to choose one.
+
+Subagents run in child sessions with fresh context. A primary agent can invoke
+one with the `subagent` tool, either in the foreground or in the background.
+You can also `@` mention a visible subagent to ask the current agent to delegate
+work to it:
+
+```text
+@explore find where authentication errors are handled
+```
+
+The parent agent's `subagent` permission controls which agents it may launch.
+The child currently uses its own configured permissions, not a restricted copy
+of the parent's permissions.
+
+## Configure agents
+
+### Markdown files
+
+The recommended file locations are:
+
+```text
+~/.config/opencode/agents/<name>.md
+.opencode/agents/<name>.md
+```
+
+OpenCode discovers project `.opencode` directories from the current directory
+up to the project root. The path below `agents/` becomes the agent ID, so
+`.opencode/agents/team/reviewer.md` defines `team/reviewer`.
+
+Frontmatter uses the same fields as an entry under `agents`. The Markdown body
+becomes `system`:
+
+```md title=".opencode/agents/reviewer.md"
+---
+description: Reviews changes without modifying files
+mode: subagent
+model: anthropic/claude-sonnet-4-5#high
+color: warning
+steps: 8
+permissions:
+  - action: edit
+    resource: "*"
+    effect: deny
+  - action: shell
+    resource: "*"
+    effect: deny
+---
+
+Review for correctness, security, regressions, and missing tests.
+List findings in severity order with file and line references.
+```
+
+### JSON or JSONC
+
+Use the `agents` field in any [OpenCode configuration file](/docs/config):
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "default_agent": "reviewer",
+  "agents": {
+    "reviewer": {
+      "description": "Reviews changes for correctness, security, and missing tests",
+      "mode": "all",
+      "model": "anthropic/claude-sonnet-4-5#high",
+      "system": "Review the current changes. Report findings before any summary.",
+      "color": "warning",
+      "steps": 8,
+      "permissions": [
+        { "action": "edit", "resource": "*", "effect": "deny" },
+        { "action": "shell", "resource": "*", "effect": "deny" }
+      ]
+    },
+    "build": {
+      "permissions": [
+        { "action": "shell", "resource": "git push *", "effect": "ask" }
+      ]
+    }
+  }
+}
+```
+
+Agent definitions merge in configuration order. Later scalar fields replace
+earlier values, request maps merge by key, and permission rules are appended.
+Global `permissions` are applied to every agent before its agent-specific rules,
+so a later agent rule can refine a global rule.
+
+## Options
+
+### `description`
+
+Explains the agent's purpose. It is optional, but strongly recommended for
+subagents because OpenCode includes it in the subagent catalog shown to the
+model.
+
+### `mode`
+
+Accepts `primary`, `subagent`, or `all`. The default is `all`.
+
+### `model`
+
+Selects a model using `provider/model` with an optional `#variant`:
+
+```jsonc
+{
+  "agents": {
+    "reviewer": {
+      "model": "anthropic/claude-sonnet-4-5#high"
+    }
+  }
+}
+```
+
+The equivalent expanded form is:
+
+```jsonc
+{
+  "agents": {
+    "reviewer": {
+      "model": {
+        "providerID": "anthropic",
+        "model": "claude-sonnet-4-5",
+        "variant": "high"
+      }
+    }
+  }
+}
+```
+
+The TUI uses this as the preferred model when the agent is selected. A child
+session uses its subagent's configured model, or inherits the parent session's
+model when none is configured. In the API, the session's selected model is
+stored separately; creating or switching a primary session with only an agent
+ID does not itself change that session model.
+
+### `system`
+
+Sets the agent's system prompt. A non-empty value replaces OpenCode's
+provider-specific base prompt for that agent. Project instructions, skills,
+references, and other instruction sources are still added separately.
+
+For a Markdown agent, use the document body instead of a `system` frontmatter
+field.
+
+### `permissions`
+
+Permissions are an ordered array of rules:
+
+```jsonc
+{
+  "agents": {
+    "orchestrator": {
+      "permissions": [
+        { "action": "subagent", "resource": "*", "effect": "deny" },
+        { "action": "subagent", "resource": "explore", "effect": "allow" },
+        { "action": "shell", "resource": "git *", "effect": "ask" }
+      ]
+    }
+  }
+}
+```
+
+Each rule has:
+
+| Field | Meaning |
+| --- | --- |
+| `action` | Tool or permission action, with `*` wildcards supported. |
+| `resource` | The path, command, agent ID, or other resource matched by the action. Wildcards are supported. |
+| `effect` | `allow`, `ask`, or `deny`. |
+
+The last matching rule wins. Important V2 action names include `shell` for
+shell commands, `edit` for all edit/write/patch tools, and `subagent` for child
+agents. Other tools generally use their tool name, such as `read`, `glob`,
+`grep`, `webfetch`, `websearch`, and `skill`.
+
+<Tip>
+  Put broad wildcard rules first and exceptions afterward. For example, deny
+  all subagents first, then allow `explore`.
+</Tip>
+
+`~` and `$HOME` are expanded in filesystem resources for `read`, `edit`, and
+`external_directory`. Shell resources are raw command text and are not
+expanded.
+
+### `steps`
+
+Sets a positive maximum number of model steps. On the final allowed step,
+OpenCode removes tools and asks the model to summarize its work in text. New
+user input resets the allowance.
+
+### `hidden`
+
+When `true`, removes the agent from normal selectors, `@` autocomplete, and the
+subagent catalog advertised to models. It is a visibility setting, not a
+security boundary.
+
+### `color`
+
+Sets the agent's UI color. Use a six-digit hex color such as `#ff6b6b`, or one
+of `primary`, `secondary`, `accent`, `success`, `warning`, `error`, or `info`.
+
+### `disabled`
+
+When `true`, removes the agent definition at that point in configuration
+loading. This works for built-in and custom agents.
+
+### `request`
+
+The V2 schema accepts per-agent request `headers` and JSON `body` overlays:
+
+```jsonc
+{
+  "agents": {
+    "reviewer": {
+      "request": {
+        "headers": { "x-agent": "reviewer" },
+        "body": { "temperature": 0.1 }
+      }
+    }
+  }
+}
+```
+
+<Warning>
+  The current V2 session runner preserves these overlays on the agent
+  definition but does not yet apply them to model requests. Configure effective
+  request settings on the provider, model, or model variant instead. Do not use
+  legacy top-level agent fields such as `temperature`, `top_p`, `prompt`,
+  `permission`, `tools`, `disable`, or `maxSteps` in new V2 configuration.
+</Warning>

+
+OpenCode can add local context to a prompt as text or image media. Current V2
+sessions make these attachment types visible to the model:
+
+| Input | Model receives |
+| --- | --- |
+| UTF-8 text file | The filename and decoded text |
+| Directory | A non-recursive listing of its immediate files and directories |
+| PNG, JPEG, GIF, or WebP | Image media |
+
+SVG files are treated as text, not image media. PDF, AVIF, BMP, audio, video,
+and other binary prompt attachments are not currently included in the model
+request. Some clients may let you select a PDF, but V2 does not yet make that
+PDF visible to the model.
+
+<Warning>
+  Use a model that supports image input before attaching an image. OpenCode
+  passes supported image media to the selected provider, but the provider and
+  model still enforce their own formats, dimensions, file counts, and size
+  limits. A text-only model may reject the request.
+</Warning>
+
+## Add attachments
+
+### TUI
+
+Type `@` followed by a filename and select the result to attach a project file.
+This is the preferred way to add source code and other text files:
+
+```text
+Explain the error handling in @src/server.ts
+```
+
+Paste an image from the clipboard with the configured paste key, `Ctrl+V` by
+default. You can also drag a supported image into a terminal that exposes the
+dropped file path to the TUI. The TUI reads PNG, JPEG, GIF, and WebP as image
+attachments; a dropped SVG is inserted as text.
+
+### Desktop and web
+
+Use **Attach file**, paste, or drag and drop. Attach UTF-8 text or a PNG, JPEG,
+GIF, or WebP image. The desktop file picker limits one selection to 20 MiB in
+total; the server also applies the per-attachment limit described below.
+
+### CLI
+
+Pass `--file` or `-f` to `opencode2 run`. Repeat the flag for multiple files:
+
+```bash
+opencode2 run -f src/server.ts -f screenshot.png "Explain the failure"
+```
+
+The run command accepts at most 100 file flags and reads at most 10 MiB per
+file. Use it for text files and the four supported image formats; other binary
+files do not become model context.
+
+### API
+
+The V2 prompt and command payloads accept a `files` array. Each item requires a
+`uri` and can include `name` and `description`:
+
+```bash
+opencode2 api post /api/session/ses_example/prompt --data '{
+  "text": "Review this file",
+  "files": [
+    {
+      "uri": "file:///home/me/project/src/server.ts",
+      "name": "server.ts",
+      "description": "Request handler"
+    }
+  ]
+}'
+```
+
+Use an absolute `file:` URL for a file available to the server, or an inline
+data URL:
+
+```json
+{
+  "text": "What is wrong with this layout?",
+  "files": [
+    {
+      "uri": "data:image/png;base64,<base64-data>",
+      "name": "layout.png"
+    }
+  ]
+}
+```
+
+HTTP and HTTPS attachment URLs are not supported. OpenCode materializes each
+attachment before admitting the prompt and rejects invalid URLs, unreadable
+paths, non-files other than directories, and attachments over 20 MiB decoded.
+For a text `file:` URL, optional positive `start` and `end` query parameters
+select one-based lines:
+
+```text
+file:///home/me/project/src/server.ts?start=20&end=60
+```
+
+The server infers the media type from the bytes. A supplied filename or data
+URL media type does not make an unsupported binary format model-visible.
+
+## Configure image processing
+
+Configure image normalization in `opencode.json` or `opencode.jsonc`:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "attachments": {
+    "image": {
+      "auto_resize": true,
+      "max_width": 2000,
+      "max_height": 2000,
+      "max_base64_bytes": 5242880
+    }
+  }
+}
+```
+
+All fields are optional:
+
+| Field | Default | Behavior |
+| --- | ---: | --- |
+| `auto_resize` | `true` | Resize an image that exceeds any configured limit. If `false`, reject it. |
+| `max_width` | `2000` | Maximum width in pixels. Must be a positive integer. |
+| `max_height` | `2000` | Maximum height in pixels. Must be a positive integer. |
+| `max_base64_bytes` | `5242880` | Maximum byte length of the Base64-encoded image string. Must be a positive integer. |
+
+<Note>
+  In the current V2 runtime, these settings apply to image media produced by
+  the built-in `read` tool. Images attached directly through the TUI, desktop,
+  web, CLI, or API bypass this normalization. Resize direct attachments before
+  adding them if the provider requires smaller media.
+</Note>
+
+The `read` tool recognizes PNG, JPEG, GIF, and WebP by their contents and will
+ingest at most 20 MiB of source image bytes. It decodes the image and compares
+its width, height, and encoded Base64 length with all three configured limits.
+
+When `auto_resize` is `true`, OpenCode preserves the aspect ratio, scales the
+image down to the dimension limits, and tries progressively smaller PNG and
+JPEG encodings until the Base64 limit is met. The resulting media type can
+therefore change to PNG or JPEG. If no encoding fits, the tool call fails.
+
+When `auto_resize` is `false`, exceeding any limit fails the tool call without
+modifying the image. An image that cannot be decoded also fails. If the image
+resizer cannot be loaded, the `read` tool returns the
+original image instead, so these settings are processing limits rather than an
+upload or security boundary.
+
+## Limits and provider behavior
+
+- Direct prompt attachments are limited to 20 MiB decoded per item by the V2
+  server. Client-specific limits can be lower.
+- `max_base64_bytes` counts the encoded Base64 characters in bytes, not the
+  decoded file size and not the complete `data:` URL.
+- Text attachments are inserted into the prompt as text and do not require a
+  multimodal model. Large text read through the `read` tool has separate
+  paging and truncation limits.
+- Image attachments use provider-native image input. Provider errors can still
+  occur when OpenCode's limits pass but the selected model's limits do not.
+- PDFs and other unsupported binary prompt attachments should be converted to
+  text or supported images before attaching them.

+
+The file body, with surrounding whitespace removed, is the command template.

+built-in or earlier command with the same name. Changes are reloaded
+automatically.
+
+Run it with:
+
+```text
+/review src/auth
+```
+
+## Configure with JSON
+
+Add commands under the `commands` key in any OpenCode JSON or JSONC
+[configuration file](/docs/config). Each entry's key is the command name and
+`template` is required.
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "commands": {
+    "review": {
+      "description": "Review code for correctness and missing tests",

+    }
+  }
+}
+```
+
+## Fields
+
+| Field | Required | Behavior |
+| --- | --- | --- |
+| `template` | JSON only | Prompt template. In a Markdown command, the file body supplies it. |
+| `description` | No | Text shown with the command in autocomplete. |
+| `agent` | No | Agent selected before the prompt runs. |
+| `model` | No | Model override in `provider/model` or `provider/model#variant` format. |
+| `subtask` | No | Accepted as a boolean, but currently has no execution effect in V2. |
+
+The four optional fields can be used in JSON or YAML frontmatter. Do not put
+`template` in frontmatter because the Markdown body always supplies it.
+
+## Arguments
+
+Use `$ARGUMENTS` for the complete argument string:
+
+```md title=".opencode/commands/component.md"
+---
+description: Create a component
+---
+
+Create a typed React component named $ARGUMENTS.
+```
+
+```text
+/component Button
+```
+
+Use `$1`, `$2`, and higher numbers for parsed positional arguments. Single and
+double quotes group text containing spaces and are removed during parsing.
+
+```md title=".opencode/commands/check.md"
+---
+description: Check one area with a specific focus
+---
+
+Check $1. Focus on $2.
+```
+
+```text
+/check src/auth "error handling and missing tests"
+```
+
+The highest-numbered positional placeholder present in the template consumes
+that argument and all remaining arguments. For example, if a template contains
+only `$1`, then `$1` receives the full parsed argument list. Missing positions
+become empty strings.
+
+If a template contains neither positional placeholders nor `$ARGUMENTS`,
+OpenCode appends non-empty arguments to the template after a blank line.
+
+## Shell interpolation
+
+Wrap a shell command in `!` followed by backticks to insert its output before
+the prompt is submitted:
+
+```md title=".opencode/commands/review-diff.md"
+---
+description: Review the current diff
+---
+
+Review this diff:
+
+!`git diff --stat && git diff`
+```
+
+OpenCode runs each interpolation with the configured shell in the active
+project location and inserts its combined output into the template. Argument
+interpolation happens first, so avoid placing untrusted arguments inside shell
+interpolations.
+
+<Warning>
+  Shell interpolations run when the command is evaluated, outside the agent's
+  tool permission flow. Only use commands from sources you trust.
+</Warning>
+
+No other template interpolation is performed. In particular, an `@path`
+written into a stored template remains ordinary prompt text; V2 does not
+automatically attach that file.
+
+## Agent, model, and execution
+
+Running a command evaluates its arguments and shell blocks, submits the result
+as a durable user prompt in the current session, and schedules normal model
+execution.
+
+If `agent` is set, it overrides the agent selected when the command was
+invoked and becomes the session's active agent. If `model` is set, it overrides
+the model. Otherwise, a model configured on the command's agent takes
+precedence over the model selected at invocation.
+
+Although `subtask` is accepted in JSON and frontmatter, V2 currently ignores
+it: commands run in the current session and do not create a child session.
+Selecting an agent whose mode is `subagent` also does not turn the command into
+a subtask.

+description: ""

+
+Compaction replaces the active model context from an older part of a session
+with a generated checkpoint. The checkpoint contains a structured summary and
+a serialized tail of recent context, so the agent can continue with more room
+in the model's context window.
+
+Compaction is lossy, but it does not delete the earlier durable session
+messages. After a successful compaction, V2 builds model requests from the
+latest completed checkpoint and the messages that follow it.
+
+## Automatic compaction
+
+Automatic compaction is enabled by default. Before a model call, V2 estimates
+the size of the final system prompt, messages, and advertised tools. It starts
+compaction when:
+
+```text
+estimated tokens > context limit - max(requested output tokens, buffer)
+```
+
+The estimate is approximate: V2 JSON-serializes the request and assumes four
+characters per token. When compaction succeeds, V2 rebuilds the request from
+the new checkpoint and retries the step without promoting the input again.
+
+V2 also recognizes provider errors classified as context overflow. If an
+overflow occurs before the provider produces assistant output or other retry
+evidence, V2 can compact and retry that step once. This recovery is attempted
+even when `auto` is `false`; `auto` controls only the preflight size check. A
+second overflow after recovery is returned as an error.

+`/summarize` is an alias. The default keybind is `<leader>c`, configured as
+`session_compact`.
+
+A manual request is durably admitted and wakes the session runner. It can
+compact short histories that would not trigger automatic compaction. If the
+session is busy, compaction runs at the next safe drain boundary before later
+steered or queued prompts are promoted. Repeated requests while one is pending
+coalesce into that pending request. Whether compaction completes or fails, the
+barrier is then settled so later prompts can proceed.
+
+The CLI has no separate `compact` subcommand. Use the TUI command or the server
+API. For example:
+
+```bash
+opencode2 api v2.session.compact \
+  --param sessionID=ses_example \
+  --data '{}'
+```
+
+The equivalent raw request is:
+
+```bash
+opencode2 api post /api/session/ses_example/compact --data '{}'
+```
+
+`POST /api/session/:sessionID/compact` returns the admitted compaction input;
+it does not wait for summary generation. Clients can call
+`client.session.compact({ sessionID })` and then wait for the session or follow
+the `session.compaction.*` events. Supplying an optional message `id` makes an
+exact retry idempotent, but reusing an ID owned by another record returns a
+conflict.
+
+## Configuration
+
+Add `compaction` to any [OpenCode configuration file](/docs/config):
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "compaction": {
+    "auto": true,
+    "prune": false,
+    "keep": {
+      "tokens": 8000
+    },
+    "buffer": 20000
+  }
+}
+```
+
+| Field | Default | V2 behavior |
+| --- | ---: | --- |
+| `auto` | `true` | Runs the preflight context-size check. It does not disable manual compaction or one-shot provider-overflow recovery. |
+| `prune` | None | Accepted by the V2 schema, but currently has no runtime effect. V2 does not prune old tool outputs in place. |
+| `keep.tokens` | `8000` | Approximate number of tokens from the newest serialized conversation context to retain beside the summary. |
+| `buffer` | `20000` | Token reserve used by the automatic threshold. The requested model output allowance wins when it is larger. |
+
+`keep.tokens` and `buffer` accept non-negative integers. Larger `keep.tokens`
+preserves more recent detail but leaves less room for future work. Larger
+`buffer` triggers preflight compaction earlier.
+
+## Checkpoint contents
+
+V2 uses the session's selected or default model to generate the summary, with
+tools disabled and at most 4096 output tokens. The summary records the
+objective, important details, completed and active work, blockers, next moves,
+and relevant files.
+
+The newest serialized context up to `keep.tokens` is retained separately. This
+is not a byte-for-byte transcript: tool output is limited to 2000 characters,
+and file or media attachments become textual descriptors rather than embedded
+data. On later compactions, V2 updates the previous summary and carries forward
+its retained recent context before selecting a new tail.
+
+The completed compaction is presented to the model as historical conversation
+context, explicitly not as new instructions. Running and failed compactions are
+not included in model context.
+
+## Compaction advances the instruction epoch
+
+Conversation compaction and instruction synchronization are separate. Before
+promoting pending input, V2 compares live instruction sources with the latest
+admitted values. Ordinary changes become durable value deltas; their
+model-facing System messages are derived during request assembly rather than
+persisted.
+
+Completed compaction advances the instruction epoch at the exact ended-event
+sequence and makes the currently admitted values initial. It does not reread
+sources or publish an instruction event. Session movement and committed revert
+clear the instruction fold so the next safe boundary requires one complete
+source read. See [Instructions](/docs/instructions) for source ordering and update
+behavior.
+
+## Current limitations
+
+- `prune` is reserved configuration; V1-style in-place tool-output pruning is
+  not implemented in V2.
+- Compaction requires a resolvable model with a positive catalog context limit.
+  There is no separate compaction-model setting or fallback model.
+- Summary generation can fail if the summary prompt itself cannot fit beside
+  its output allowance, the model returns no summary, or the provider fails.
+- Automatic and overflow compaction need older conversation context that can be
+  replaced. A provider overflow can still surface when there is no compressible
+  head or fixed instructions and tool schemas dominate the request.
+- Overflow recovery retries only once per step. Token estimation is heuristic,
+  so it cannot prevent every provider-specific overflow.
+- Earlier durable messages remain stored even though they are no longer in the
+  active model context.
+
+V1 used additional tail-turn and pruning behavior. Those V1 details are only
+migration context; the settings and behavior on this page describe V2.

+
+<Tip>
+  You shouldn't have to configure OpenCode manually. Ask OpenCode to update its configuration for you.
+</Tip>
+
+## Format
+
+OpenCode supports both **JSON** and **JSONC** (JSON with Comments) configuration files.
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "model": "openai/gpt-5.2-custom",
+  "providers": {
+    "openai": {
+      "models": {
+        "gpt-5.2-custom": {
+          "modelID": "gpt-5.2",
+          "name": "GPT-5.2 Custom"
+        }
+      }
+    }
+  }
+}
+```
+
+## Locations
+
+OpenCode loads global configuration from:
+
+```text
+~/.config/opencode/opencode.json(c)
+```
+
+Project-specific configuration can use either form:
+
+```text
+/home/user/projects/my-app/opencode.json(c)
+/home/user/projects/my-app/.opencode/opencode.json(c)
+```
+
+When OpenCode starts, it searches for configuration files from the current
+directory upward to the project root. It merges direct `opencode.json(c)` files
+from the project root toward the current directory, then does the same for
+files inside `.opencode` directories. A `.opencode` config therefore overrides
+every direct config, even when the direct config is closer to the current
+directory. Avoid mixing the two forms across one project hierarchy unless this
+precedence is intentional.
+
+For example, consider a monorepo with OpenCode started from
+`/home/user/projects/acme/packages/web`:
+
+```text
+~/.config/opencode/opencode.json
+
+/home/user/projects/acme/
+├── opencode.json
+└── packages/
+    └── web/
+        ├── opencode.json
+        └── src/
+```
+
+OpenCode applies these files from lowest to highest precedence:
+
+1. `~/.config/opencode/opencode.json`
+2. `/home/user/projects/acme/opencode.json`
+3. `/home/user/projects/acme/packages/web/opencode.json`
+
+In this direct-config example, the package config overrides matching settings
+from the repository config, which overrides matching settings from the global
+config. Settings that do not conflict are preserved from every file.
+
+## Schema
+
+The complete OpenCode configuration schema is available at
+[opencode.ai/config.json](https://opencode.ai/config.json).
+
+Add the `$schema` field to your configuration file to enable validation and
+autocomplete in editors that support JSON Schema:
+
+```json title="opencode.json"
+{
+  "$schema": "https://opencode.ai/config.json"
+}
+```
+
+Use the schema as the source of truth for available fields, accepted values,
+and nested configuration shapes.
+
+### Shell
+
+Set the shell used by the terminal and shell tools.
+
+```jsonc
+{
+  "shell": "/bin/zsh"
+}
+```
+
+### Model
+
+Set the default model in `provider/model` format. The root default currently
+does not retain a `#variant`; select variants in the TUI or on an agent or command.
+
+```jsonc
+{
+  "model": "anthropic/claude-sonnet-4-5"
+}
+```
+
+See the [models guide](/docs/models) for model selection
+and local models.
+
+### Default agent
+
+Choose the primary agent used when a session does not select one explicitly.
+
+```jsonc
+{
+  "default_agent": "build"
+}
+```
+
+See the [agents guide](/docs/agents) for built-in and custom
+agents.
+
+### Autoupdate
+
+Control automatic updates from the global config. Set this to `false` to
+disable updates. The current beta treats `true` and `"notify"` identically and
+automatically installs compatible non-major updates; project-level values are
+ignored.
+
+```jsonc
+{
+  "autoupdate": false
+}
+```
+
+### Sharing
+
+Set the intended session sharing policy. V2 accepts this field, but session
+sharing is not implemented yet.
+
+```jsonc
+{
+  "share": "manual"
+}
+```
+
+See the [sharing guide](/docs/sharing) for more details.
+
+### Username
+
+Set a username for future display behavior. V2 accepts this field but does not
+currently display it in conversations.
+
+```jsonc
+{
+  "username": "alice"
+}
+```
+
+### Permissions
+
+Define ordered rules that allow, deny, or ask before an agent uses a tool on a
+matching resource.
+
+```jsonc
+{
+  "permissions": [
+    {
+      "action": "shell",
+      "resource": "git push *",
+      "effect": "ask"
+    }
+  ]
+}
+```
+
+See the [permissions guide](/docs/permissions) for rule matching and available actions.
+
+### Agents
+
+Override built-in agents or define specialized agents with their own model,
+instructions, mode, and permissions.
+
+```jsonc
+{
+  "agents": {
+    "reviewer": {
+      "description": "Review changes without editing files",
+      "mode": "subagent",
+      "system": "Focus on correctness, security, and missing tests.",
+      "permissions": [
+        { "action": "edit", "resource": "*", "effect": "deny" }
+      ]
+    }
+  }
+}
+```
+
+See the [agents guide](/docs/agents) for all agent options and file-based agents.
+
+### Snapshots
+
+Enable or disable filesystem snapshots used by undo and revert behavior.
+
+```jsonc
+{
+  "snapshots": false
+}
+```
+
+See the [snapshots guide](/docs/snapshots) for undo and redo behavior.
+
+### Watcher
+
+Ignore files and directories that should not trigger filesystem updates.
+
+```jsonc
+{
+  "watcher": {
+    "ignore": ["dist/**", "coverage/**"]
+  }
+}
+```
+
+### Formatter
+
+Define formatter settings for compatibility and future use. V2 accepts this
+field, but it does not run formatters yet.
+
+```jsonc
+{
+  "formatter": {
+    "prettier": {
+      "command": ["bunx", "prettier", "--write", "$FILE"],
+      "extensions": [".js", ".ts", ".tsx"]
+    }
+  }
+}
+```
+
+See the [formatters guide](/docs/formatters) for accepted fields and current limitations.
+
+### LSP
+
+Define language server settings for compatibility and future use. V2 accepts
+this field, but it does not start language servers yet.
+
+```jsonc
+{
+  "lsp": {
+    "typescript": {
+      "command": ["typescript-language-server", "--stdio"],
+      "extensions": [".ts", ".tsx"]
+    }
+  }
+}
+```
+
+See the [LSP guide](/docs/lsp) for accepted fields and current limitations.
+
+### Attachments
+
+Control how oversized images loaded by the `read` tool are resized or rejected
+before they are sent to a model.
+
+```jsonc
+{
+  "attachments": {
+    "image": {
+      "auto_resize": true,
+      "max_width": 2000,
+      "max_height": 2000,
+      "max_base64_bytes": 5242880
+    }
+  }
+}
+```
+
+See the [attachments guide](/docs/attachments) for image processing and limits.
+
+### Tool output
+
+Set the maximum number of lines and bytes retained from a tool result.
+
+```jsonc
+{
+  "tool_output": {
+    "max_lines": 2000,
+    "max_bytes": 51200
+  }
+}
+```
+
+### MCP
+
+Configure local and remote Model Context Protocol servers. Global timeouts can
+be overridden by an individual server.
+
+```jsonc
+{
+  "mcp": {
+    "servers": {
+      "playwright": {
+        "type": "local",
+        "command": ["bunx", "@playwright/mcp"]
+      }
+    }
+  }
+}
+```
+
+See the [MCP guide](/docs/mcp-servers) for remote servers, OAuth, environment variables, and timeouts.
+
+### Compaction
+
+Control automatic context compaction and how much recent context it preserves.
+
+```jsonc
+{
+  "compaction": {
+    "auto": true,
+    "keep": {
+      "tokens": 8000
+    },
+    "buffer": 20000
+  }
+}
+```
+
+See the [compaction guide](/docs/compaction) for automatic context management.
+
+### Skills
+
+Add directories or URLs that OpenCode should search for agent skills.
+
+```jsonc
+{
+  "skills": ["./team-skills", "https://example.com/.well-known/skills/"]
+}
+```
+
+See the [skills guide](/docs/skills) for skill structure and automatic discovery under `.opencode/skills/`.
+
+### Commands
+
+Define reusable slash commands as named prompt templates.
+
+```jsonc
+{
+  "commands": {
+    "review": {
+      "description": "Review the current changes",
+      "template": "Review the current diff for correctness and missing tests."
+    }
+  }
+}
+```
+
+See the [commands guide](/docs/commands) for arguments, models, agents, and file-based commands.
+
+### Instructions
+
+Declare additional instruction files, globs, or URLs. V2 accepts this field,
+but does not load these entries yet; use `AGENTS.md` for active instructions.
+
+```jsonc
+{
+  "instructions": ["CONTRIBUTING.md", "docs/guidelines/*.md"]
+}
+```
+
+See the [instructions guide](/docs/instructions) for project instructions and `AGENTS.md`.
+
+### References
+
+Make local directories or Git repositories available as named supporting
+context.
+
+```jsonc
+{
+  "references": {
+    "docs": {
+      "path": "../product-docs",
+      "description": "Product behavior and terminology"
+    },
+    "effect": {
+      "repository": "Effect-TS/effect",
+      "branch": "main"
+    }
+  }
+}
+```
+
+See the [references guide](/docs/references) for shorthand, visibility, and path resolution.
+
+### Plugins
+
+Load plugins from packages or local files. Use the object form when a plugin
+accepts options.
+
+```jsonc
+{
+  "plugins": [
+    "opencode-example-plugin",
+    {
+      "package": "./plugins/local.ts",
+      "options": {
+        "enabled": true
+      }
+    }
+  ]
+}
+```
+
+See the [plugins guide](/docs/build/plugins) for plugin development and configuration.
+
+### Providers
+
+Configure providers and add or override their models, request settings,
+headers, and model variants.
+
+```jsonc
+{
+  "providers": {
+    "openai": {
+      "models": {
+        "gpt-5.2-custom": {
+          "modelID": "gpt-5.2",
+          "name": "GPT-5.2 Custom",
+          "limit": {
+            "context": 200000,
+            "output": 32000
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+See the [providers guide](/docs/providers) for credentials, custom endpoints, provider packages, and model configuration.

+
+OpenCode V2 accepts formatter configuration, but it does not yet include a
+formatter runtime. File writes and edits are not automatically formatted.
+
+<Warning>
+  V2 currently has no built-in formatters. The built-in formatter list and
+  automatic post-edit formatting documented for V1 do not apply to V2.
+</Warning>
+
+## Configuration
+
+The `formatter` field accepts a boolean or an object keyed by formatter name:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "formatter": {
+    "prettier": {
+      "disabled": false,
+      "command": ["prettier", "--write", "$FILE"],
+      "environment": {
+        "NODE_ENV": "development"
+      },
+      "extensions": [".js", ".jsx", ".ts", ".tsx"]
+    }
+  }
+}
+```
+
+This example is valid V2 configuration, but V2 does not currently execute the
+command.
+
+Each named formatter entry supports these optional fields:
+
+| Field | Type | Current V2 behavior |
+| --- | --- | --- |
+| `disabled` | `boolean` | Accepted, but there is no runtime formatter to enable or disable. |
+| `command` | `string[]` | Accepted as an argument array, but not executed. |
+| `environment` | `Record<string, string>` | Accepts string environment variable names and values, but they are not applied. |
+| `extensions` | `string[]` | Accepted without extension-specific validation, but files are not matched against it. |
+
+All entry fields are optional. The schema therefore also accepts an empty entry
+such as `"prettier": {}`.
+
+## Enable and disable
+
+The schema accepts all of the following forms:
+
+```jsonc
+// Omit `formatter`, or use false, when formatting is not requested.
+{
+  "formatter": false
+}
+```
+
+```jsonc
+// Reserved for enabling all built-ins once a V2 runtime provides them.
+{
+  "formatter": true
+}
+```
+
+```jsonc
+// Configure named entries or mark one as disabled.
+{
+  "formatter": {
+    "prettier": { "disabled": true },
+    "custom": {
+      "command": ["custom-fmt", "$FILE"],
+      "extensions": [".foo"]
+    }
+  }
+}
+```
+
+At present, omitted, `false`, `true`, and object forms have the same runtime
+result: V2 runs no formatter. `disabled` is retained as configuration data but
+does not control an executable formatter.
+
+## Commands and placeholders
+
+`command` is an array of strings, not a shell command string. `$FILE` is the V1
+file-path placeholder and is often retained in migrated configuration. V2 does
+not currently substitute `$FILE` or define another formatter placeholder.
+
+Likewise, V2 does not currently use `extensions` to select commands, merge
+`environment` into a child process, discover formatter executables or project
+configuration, or run multiple matching formatters. These behaviors will only
+be available after a V2 formatter runtime is implemented.

+
+#### Prerequisites
+
+To use OpenCode in your terminal, you'll need:
+
+1. A modern terminal emulator like:
+   - [Ghostty](https://ghostty.org), Linux and macOS
+   - [WezTerm](https://wezterm.org), cross-platform
+   - [Alacritty](https://alacritty.org), cross-platform
+   - [Kitty](https://sw.kovidgoyal.net/kitty/), Linux and macOS
+2. API keys for the LLM providers you want to use.
+
+---
+
+## Connect
+
+With OpenCode you can use any LLM provider by configuring its API key.
+
+Run `/connect` in the TUI and select your provider.
+
+```text
+/connect
+```
+
+If you'd like easy access to all the best coding models you can try out
+[OpenCode Console](https://console.opencode.ai).
+
+You can also try [OpenCode Go](https://opencode.ai/go) a $10/month subscription
+plan that grants you access to the best open source models.
+
+Use `/models` to browse the providers and models available to your project. See [Providers](/docs/providers) for connection and
+configuration details.
+
+---
+
+## Usage
+
+You are now ready to use OpenCode in your project. Here are a few common workflows.
+
+### Ask questions
+
+Ask OpenCode to explain your codebase.
+
+<Tip>Use `@` to fuzzy search for files in the project.</Tip>
+
+```text
+How is authentication handled in @packages/functions/src/api/index.ts
+```
+
+### Add features
+
+Ask OpenCode to add a feature by describing the desired behavior and providing relevant context.
+
+```text
+When a user deletes a note, flag it as deleted in the database.
+Create a screen that shows recently deleted notes.
+From this screen, the user can restore a note or permanently delete it.
+```
+
+<Tip>Give OpenCode plenty of context and examples.</Tip>
+
+### Undo changes
+
+Use `/undo` when a change isn't what you wanted.
+
+```text
+/undo
+```
+
+OpenCode stages a conversation revert and restores your original message so you can revise it. In a Git repository, it
+also restores file changes when snapshots were captured successfully. Run `/undo` multiple times to move the conversation
+boundary back, or use `/redo` to restore the staged conversation and files. See [Undo](/docs/snapshots) for
+limitations and safety details.
+
+```text
+/redo
+```
+
+---
+
+## Customize
+
+Make OpenCode your own by [picking a theme](https://opencode.ai/docs/themes), [customizing
+keybinds](https://opencode.ai/docs/keybinds), [configuring formatters](/docs/formatters), [creating commands](/docs/commands), or
+editing the [OpenCode config](/docs/config).

+Instructions are privileged context that guide an agent throughout a session.
+V2 combines built-in context, discovered `AGENTS.md` files, and dynamic sources
+such as skill, reference, MCP, and session context. It stores source values as
+durable deltas, then renders initial instructions and chronological updates when
+assembling each model request.
+
+## AGENTS.md
+
+Use `AGENTS.md` for persistent guidance such as build commands, architecture,
+code conventions, and verification requirements. Commit project files so the
+whole team receives the same instructions.
+
+V2 loads:
+
+1. The global file at `$XDG_CONFIG_HOME/opencode/AGENTS.md`, normally
+   `~/.config/opencode/AGENTS.md`.
+2. Every `AGENTS.md` from the current Location up to and including the project
+   root.
+
+For example, when the Location is `packages/web`, OpenCode can load all three
+project files below:
+
+```text
+my-project/
+├── AGENTS.md
+└── packages/
+    ├── AGENTS.md
+    └── web/
+        └── AGENTS.md
+```
+
+The files are combined rather than selecting a single winner. They are rendered
+in this order: global, then project files from the Location toward the project
+root. OpenCode does not resolve conflicts between their contents, so keep broad
+guidance global and put scoped guidance in the relevant project directory.
+
+If the Location is outside the project root, only the global file is loaded.
+Setting `OPENCODE_DISABLE_PROJECT_CONFIG=1` also skips project `AGENTS.md`
+discovery but does not disable the global file.
+
+<Note>
+  Current V2 discovery only recognizes `AGENTS.md`. The `CLAUDE.md` fallback
+  and related precedence described by older OpenCode documentation do not apply.
+</Note>
+
+### Nested instructions
+
+An `AGENTS.md` below the Location is not part of the initial upward scan. When
+the read tool successfully reads a file or lists a directory, OpenCode discovers
+`AGENTS.md` files from that target upward to, but not including, the Location.
+It adds newly discovered files to the session in nearest-first order.
+
+Each nested file is injected once per session and recorded in durable session
+history. Reading the same area again does not inject it again. Consequently,
+editing an already injected nested `AGENTS.md` does not replace its earlier
+session entry automatically; start a new session if the updated text must apply
+immediately.
+
+## Config entries
+
+The V2 config schema accepts an `instructions` array of strings:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "instructions": [
+    "CONTRIBUTING.md",
+    "docs/guidelines/*.md",
+    "https://example.com/shared-instructions.md"
+  ]
+}
+```
+
+Configuration is loaded from global through project-local files. If more than
+one config defines `instructions`, the highest-precedence, closest config's
+entire array is selected; arrays are not merged.
+
+<Warning>
+  V2 currently parses and retains this field but does not resolve its entries
+  into instruction sources. Local files, glob patterns, and HTTP or HTTPS URLs
+  in `instructions` therefore do not reach the model yet. Use `AGENTS.md` for
+  active V2 instructions. URL fetching and timeout behavior documented for V1
+  are not supported by the current V2 implementation.
+</Warning>
+
+See [Config](/docs/config) for config locations and general precedence.
+
+## Ordering
+
+The selected agent or provider system prompt is sent first. OpenCode then sends
+the session's initial instructions, composed in this order:
+
+1. Built-in environment and date context.
+2. Ambient `AGENTS.md` discovery.
+3. Available skill, reference, and MCP guidance.
+4. Session-specific instruction entries supplied through the API.
+
+These sources are combined; ordering is not an override mechanism. Nested
+`AGENTS.md` files discovered by reads are chronological session entries rather
+than part of the initial instructions.
+
+## Changes
+
+Before promoting pending input, V2 compares live instruction sources with the
+latest admitted source values:
+
+- A new or changed ambient `AGENTS.md` aggregate is announced as a system update
+  that replaces the previous ambient aggregate.
+- Removing all ambient files announces that the previous ambient instructions
+  no longer apply.
+- A temporary read or discovery failure preserves the session's last known
+  instructions instead of treating them as deleted. If no instruction epoch
+  exists yet, pending input waits until every source is available.
+- Completed conversation compaction advances the instruction epoch, making the
+  currently admitted values initial without rereading sources or authoring an
+  instruction event.
+- Moving a session or committing a revert clears the instruction fold. The next
+  safe boundary requires one complete source read before promoting input.
+
+The durable event stores changed source keys and value hashes, not rendered
+prose. During request assembly, OpenCode renders the epoch's initial values and
+interleaves later changes as chronological System messages. Clients see changed
+keys but never the privileged value bodies.

+description: ""

+
+Language Server Protocol (LSP) integrations can provide code diagnostics,
+symbols, definitions, references, and other language-aware context.
+
+<Warning>
+  OpenCode V2 does not yet have an LSP runtime or built-in language servers.
+  The `lsp` configuration is accepted and preserved, but it does not currently
+  start or download servers, expose an LSP tool, or add diagnostics to file tool
+  results.
+</Warning>
+
+## Built-in servers
+
+There are no built-in LSP servers in the current V2 implementation. Setting
+`lsp` to `true` declares that built-ins should be enabled, but has no runtime
+effect until V2 provides a server registry and LSP runtime.
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "lsp": true
+}
+```
+
+## Configuration
+
+The `lsp` field accepts a boolean or an object keyed by server name:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "lsp": {
+    "custom-typescript": {
+      "command": ["typescript-language-server", "--stdio"],
+      "extensions": [".ts", ".tsx"],
+      "env": {
+        "TSS_LOG": "-level verbose"
+      },
+      "initialization": {
+        "preferences": {
+          "importModuleSpecifierPreference": "relative"
+        }
+      }
+    }
+  }
+}
+```
+
+Each enabled server entry has this shape:
+
+| Property | Type | Required | Description |
+| --- | --- | --- | --- |
+| `command` | `string[]` | Yes | Executable followed by any arguments. |
+| `extensions` | `string[]` | No | File extensions associated with the server, including the leading dot. |
+| `disabled` | `boolean` | No | Disables the entry when `true`. |
+| `env` | `Record<string, string>` | No | Environment variables for the server process. The property is named `env`, not `environment`. |
+| `initialization` | `Record<string, unknown>` | No | Server-specific options for the LSP `initialize` request. |
+
+The only entry that may omit `command` is the disable-only form:
+
+```jsonc
+{
+  "lsp": {
+    "typescript": {
+      "disabled": true
+    }
+  }
+}
+```
+
+Server names are arbitrary. The V2 schema permits `extensions` to be omitted,
+including for a custom server, although a future runtime will need a way to
+associate that server with files.
+
+## Disable LSP
+
+Omit `lsp` when no configuration is needed. Set it to `false` to explicitly
+disable the whole integration, including when a lower-priority configuration
+set it to `true` or supplied an object:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "lsp": false
+}
+```
+
+Use `{ "disabled": true }` under a server name to disable one server while
+retaining the object form. `OPENCODE_DISABLE_LSP_DOWNLOAD` is not used by V2;
+V2 currently performs no automatic LSP downloads.
+
+## Current usage
+
+V2 loads and validates the configuration shape for compatibility and future
+integration. It does not currently use LSP when reading, writing, editing, or
+patching files, and those tools do not notify a language server or return LSP
+diagnostics.
+
+For reliable feedback today, have the agent run the project's lint, typecheck,
+test, or compiler commands. Record those commands in an `AGENTS.md` file or a
+skill so the agent knows when and where to run them.

+title: "MCP servers"
+description: ""
+---
+
+OpenCode can connect to [Model Context Protocol](https://modelcontextprotocol.io/) servers and make their tools, prompts, and instructions available to agents. MCP tools consume model context, so enable only the servers you need.
+
+## Configure servers
+
+Define each server by a unique name under `mcp.servers` in your [OpenCode configuration](/docs/config). V2 does not place server names directly under `mcp`.
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "servers": {
+      "my-server": {
+        "type": "local",
+        "command": ["npx", "-y", "example-mcp-server"]
+      }
+    }
+  }
+}
+```
+
+Servers connect automatically unless `disabled` is `true`. There is no V2 `enabled` field.
+
+```jsonc
+{
+  "mcp": {
+    "servers": {
+      "my-server": {
+        "type": "local",
+        "command": ["npx", "-y", "example-mcp-server"],
+        "disabled": true
+      }
+    }
+  }
+}
+```
+
+As with other configuration, a server in a higher-precedence project config replaces a server with the same name from a lower-precedence config. Use different names when you need separate connections or accounts.
+
+## Local servers
+
+A local server is a command that OpenCode starts using the MCP stdio transport.
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "servers": {
+      "everything": {
+        "type": "local",
+        "command": [
+          "npx",
+          "-y",
+          "@modelcontextprotocol/server-everything"
+        ],
+        "cwd": ".",
+        "environment": {
+          "LOG_LEVEL": "info",
+          "MCP_API_KEY": "{env:MCP_API_KEY}"
+        }
+      }
+    }
+  }
+}
+```
+
+| Field | Required | Description |
+| --- | --- | --- |
+| `type` | Yes | Must be `"local"`. |
+| `command` | Yes | Executable followed by its arguments. |
+| `cwd` | No | Process working directory. Relative paths resolve from the workspace directory; the workspace is the default. |
+| `environment` | No | String environment variables added to the inherited OpenCode process environment. |
+| `disabled` | No | Set to `true` to prevent the server from connecting. Defaults to `false`. |
+| `timeout` | No | Per-server timeout overrides. |
+
+Use `{env:NAME}` to substitute an environment variable while loading config. Shell expressions such as `$NAME` are not expanded in JSON strings.
+
+## Remote servers
+
+A remote server uses the MCP Streamable HTTP transport. Its `url` must be a valid absolute URL.
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "servers": {
+      "context7": {
+        "type": "remote",
+        "url": "https://mcp.context7.com/mcp",
+        "oauth": false,
+        "headers": {
+          "CONTEXT7_API_KEY": "{env:CONTEXT7_API_KEY}"
+        }
+      }
+    }
+  }
+}
+```
+
+| Field | Required | Description |
+| --- | --- | --- |
+| `type` | Yes | Must be `"remote"`. |
+| `url` | Yes | Streamable HTTP endpoint. |
+| `headers` | No | String HTTP headers sent to the MCP endpoint. |
+| `oauth` | No | OAuth client settings, or `false` to disable OAuth support. |
+| `disabled` | No | Set to `true` to prevent the server from connecting. Defaults to `false`. |
+| `timeout` | No | Per-server timeout overrides. |
+
+Use `oauth: false` for a server that exclusively uses an API key or another header-based credential.
+
+## OAuth
+
+OAuth support is enabled for remote servers unless `oauth` is `false`. OpenCode discovers the authorization server, uses PKCE, refreshes tokens, and attempts dynamic client registration when the server supports it. OAuth credentials are stored outside project configuration.
+
+For a server that supports dynamic client registration, only the remote server is required:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "servers": {
+      "sentry": {
+        "type": "remote",
+        "url": "https://mcp.sentry.dev/mcp"
+      }
+    }
+  }
+}
+```
+
+When the server reports that it needs authentication, run `/connect` in the TUI:
+
+```text
+/connect
+```
+
+Select the MCP server under **Services**, then complete the browser authorization flow.
+
+You can also authenticate from the command line:
+
+```bash
+opencode2 mcp auth sentry
+```
+
+The CLI command prints the authorization URL and waits for the redirect to OpenCode's loopback callback server.
+
+If the provider issued client credentials, configure them using V2's snake_case field names:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "servers": {
+      "company-tools": {
+        "type": "remote",
+        "url": "https://mcp.example.com/mcp",
+        "oauth": {
+          "client_id": "{env:MCP_CLIENT_ID}",
+          "client_secret": "{env:MCP_CLIENT_SECRET}",
+          "scope": "tools:read tools:execute",
+          "callback_port": 19876,
+          "redirect_uri": "http://127.0.0.1:19876/callback"
+        }
+      }
+    }
+  }
+}
+```
+
+| OAuth field | Description |
+| --- | --- |
+| `client_id` | Pre-registered OAuth client ID. If omitted, OpenCode attempts dynamic client registration. |
+| `client_secret` | Client secret for a pre-registered client. |
+| `scope` | Space-delimited scopes to request. |
+| `callback_port` | Local callback port, from `1` through `65535`. An available ephemeral port is used by default. |
+| `redirect_uri` | Pre-registered loopback redirect URI. Its path and port must reach the local callback listener. |
+
+Remove stored credentials with:
+
+```bash
+opencode2 mcp logout sentry
+```
+
+## Timeouts
+
+Timeouts are positive integer milliseconds. Configure defaults under `mcp.timeout`; a server's `timeout` fields override matching defaults.
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "timeout": {
+      "startup": 45000,
+      "catalog": 30000,
+      "execution": 600000
+    },
+    "servers": {
+      "slow-tools": {
+        "type": "remote",
+        "url": "https://mcp.example.com/mcp",
+        "timeout": {
+          "catalog": 60000
+        }
+      }
+    }
+  }
+}
+```
+
+| Timeout | Default | Applies to |
+| --- | --- | --- |
+| `startup` | 30 seconds | Establishing the transport and initializing the server. |
+| `catalog` | 30 seconds | Listing tools, prompts, resources, and resource templates. |
+| `execution` | 12 hours | Calling tools, getting prompts, and reading resources. |
+
+## Names and permissions
+
+OpenCode combines the server name and MCP tool name as `<server>_<tool>`. Characters other than letters, numbers, `_`, and `-` are replaced with `_`; for example, server `context 7` and tool `resolve.library/id` become `context_7_resolve_library_id`. MCP prompts appear as slash commands named `<server>:<prompt>` using the same normalization.
+
+Choose short server names that remain unique after normalization. Under the default Code Mode, MCP tools are grouped by the normalized server name.
+
+Use permission actions to hide or deny a server's tools without stopping its connection:
+
+```jsonc
+{
+  "permissions": [
+    {
+      "action": "context7_*",
+      "resource": "*",
+      "effect": "deny"
+    }
+  ]
+}
+```
+
+## CLI commands
+
+V2 provides these MCP management commands:
+
+```bash
+# Add a local server to the project config
+opencode2 mcp add everything --env LOG_LEVEL=info -- npx -y @modelcontextprotocol/server-everything
+
+# Add a remote server to the project config
+opencode2 mcp add context7 --url https://mcp.context7.com/mcp --header 'CONTEXT7_API_KEY={env:CONTEXT7_API_KEY}'
+
+# Add to the global config instead
+opencode2 mcp add context7 --global --url https://mcp.context7.com/mcp
+
+# List configured servers and connection status
+opencode2 mcp list
+
+# Authenticate or remove OAuth credentials
+opencode2 mcp auth context7
+opencode2 mcp logout context7
+```
+
+`mcp add` accepts either `--url` for a remote server or a command after `--` for a local server, not both. Use `--header NAME=VALUE` only with remote servers and `--env NAME=VALUE` only with local servers. Edit the config directly for OAuth, timeout, working-directory, or enablement settings.

+title: "Migrate from V1"
+description: "Move from OpenCode V1 to the OpenCode 2.0 beta."
+---
+
+## Breaking changes
+
+V2 has three intentional breaking changes:
+
+- [Plugins](#plugins) use a new plugin API.
+- The [server API and clients](#server-api-and-clients) have new contracts.
+- [TUI configuration](#tui-configuration) moves from layered `tui.json(c)` files to one global `cli.json` file (auto migrated).
+
+All other functionality is intended to remain compatible with V1.
+
+Existing server config files, agent definitions, command definitions, skills, and other files in `.opencode/` should
+continue to work without changes. If one of these stops working in V2, treat it as a beta compatibility bug rather than
+an expected migration requirement.
+
+<Tip>
+  Run `/report` if existing V1 functionality does not work in V2. The report skill collects diagnostics and helps you file
+  a compatibility issue.
+</Tip>
+
+<Warning>
+  OpenCode 2.0 is in beta. Beta data may be wiped, features may break unintentionally, and the server and plugin APIs may
+  continue to change.
+</Warning>
+
+During the beta, OpenCode V1 and V2 use different executable names. You can keep using `opencode` for V1 while trying V2
+with `opencode2`.
+
+## Install the beta
+
+Install the beta from the `next` distribution tag:
+
+```bash
+npm install -g @opencode-ai/cli@next
+```
+
+Start it in your project with:
+
+```bash
+opencode2
+```
+
+## Configuration
+
+This section covers both JSON/JSONC configuration and file-based definitions under `.opencode/`.
+
+### Use your existing configuration
+
+V2 reads existing global and project configuration from the same locations as V1:
+
+```text
+~/.config/opencode/opencode.json(c)
+<project>/opencode.json(c)
+<project>/.opencode/opencode.json(c)
+```
+
+V2 reads these same locations. It detects V1-shaped configuration and translates it in memory without rewriting the
+source file. Existing V1 configuration is intended to keep working, so you do not need to convert it to try or adopt V2.
+
+### Ask OpenCode to migrate
+
+The V1 config format remains supported. The native V2 format is optional and makes several settings more explicit and
+ergonomic.
+
+The recommended migration path is to ask OpenCode to update the configuration for you:
+
+```text
+Migrate my OpenCode configuration, including file-based definitions, from the V1 format to the native V2 format.
+Preserve its behavior and all unrelated settings.
+```
+
+OpenCode can inspect the complete file, apply the relevant changes below, and avoid rewriting settings that do not need to
+change. Do not mix V1 and V2 field names manually in one file.
+
+### Sharing
+
+The deprecated V1 `autoshare` boolean becomes the explicit `share` policy:
+
+```jsonc
+// V1
+{ "autoshare": true }
+
+// V2
+{ "share": "auto" }
+```
+
+Use `"manual"`, `"auto"`, or `"disabled"`. If the V1 file already uses `share`, no change is needed.
+
+### Permissions and tools
+
+V1 groups permission effects by tool. V2 uses one ordered `permissions` array, making precedence and exceptions explicit:
+
+```jsonc
+// V1
+{
+  "permission": {
+    "bash": {
+      "git push *": "ask"
+    },
+    "edit": "allow"
+  },
+  "tools": {
+    "websearch": false
+  }
+}
+
+// V2
+{
+  "permissions": [
+    { "action": "shell", "resource": "git push *", "effect": "ask" },
+    { "action": "edit", "resource": "*", "effect": "allow" },
+    { "action": "websearch", "resource": "*", "effect": "deny" }
+  ]
+}
+```
+
+Permission actions also changed: `bash` is now `shell`, `task` is now `subagent`, and `write` and `patch` are now `edit`.
+See [Permissions](/docs/permissions) for the ordered V2 rule format.
+
+### Agents and modes
+
+The singular `agent` and deprecated `mode` maps become `agents`. Agent fields become more consistent with the rest of the
+V2 config:
+
+```jsonc
+// V1
+{
+  "agent": {
+    "reviewer": {
+      "prompt": "Review for correctness and missing tests.",
+      "model": "anthropic/claude-sonnet-4-5",
+      "variant": "high",
+      "disable": false,
+      "permission": {
+        "edit": "deny"
+      }
+    }
+  }
+}
+
+// V2
+{
+  "agents": {
+    "reviewer": {
+      "system": "Review for correctness and missing tests.",
+      "model": "anthropic/claude-sonnet-4-5#high",
+      "disabled": false,
+      "permissions": [
+        { "action": "edit", "resource": "*", "effect": "deny" }
+      ]
+    }
+  }
+}
+```
+
+`prompt` becomes `system`, `disable` becomes `disabled`, and a separate `variant` joins the model reference after `#`.
+`temperature`, `top_p`, and provider-specific `options` move under `request.body`. `maxSteps` becomes `steps`. Entries from
+the old `mode` map become primary agents.
+
+### Snapshots
+
+Rename the singular `snapshot` field to `snapshots`. Its boolean value does not change:
+
+```jsonc
+// V1
+{ "snapshot": false }
+
+// V2
+{ "snapshots": false }
+```
+
+### Attachments
+
+Rename the singular `attachment` object to `attachments`. Nested image settings keep the same names:
+
+```jsonc
+// V1
+{ "attachment": { "image": { "auto_resize": true } } }
+
+// V2
+{ "attachments": { "image": { "auto_resize": true } } }
+```
+
+### MCP servers
+
+V2 groups servers under `mcp.servers`, replaces `enabled` with the inverse `disabled`, and separates timeout purposes:
+
+```jsonc
+// V1
+{
+  "mcp": {
+    "playwright": {
+      "type": "local",
+      "command": ["npx", "@playwright/mcp"],
+      "enabled": true,
+      "timeout": 30000
+    }
+  }
+}
+
+// V2
+{
+  "mcp": {
+    "servers": {
+      "playwright": {
+        "type": "local",
+        "command": ["npx", "@playwright/mcp"],
+        "disabled": false,
+        "timeout": {
+          "catalog": 30000,
+          "execution": 30000
+        }
+      }
+    }
+  }
+}
+```
+
+Remote OAuth fields use snake case: `clientId` becomes `client_id`, `clientSecret` becomes `client_secret`,
+`callbackPort` becomes `callback_port`, and `redirectUri` becomes `redirect_uri`. The V1 `experimental.mcp_timeout` value
+also becomes the default `mcp.timeout.catalog` and `mcp.timeout.execution` values. See [MCP servers](/docs/mcp-servers).
+
+### Compaction
+
+V2 groups the retained-context token budget under `keep` and gives the reserve a clearer name:
+
+```jsonc
+// V1
+{
+  "compaction": {
+    "preserve_recent_tokens": 8000,
+    "reserved": 20000
+  }
+}
+
+// V2
+{
+  "compaction": {
+    "keep": {
+      "tokens": 8000
+    },
+    "buffer": 20000
+  }
+}
+```
+
+`auto` and `prune` keep their names. V2 has no native `tail_turns` field; recent context is retained by token budget instead.
+See [Compaction](/docs/compaction).
+
+### Skills
+
+V1 separates extra skill paths and URLs. V2 combines both into one ordered array:
+
+```jsonc
+// V1
+{
+  "skills": {
+    "paths": ["./team-skills"],
+    "urls": ["https://example.com/skills/"]
+  }
+}
+
+// V2
+{
+  "skills": ["./team-skills", "https://example.com/skills/"]
+}
+```
+
+Existing skill files and automatic `.opencode/skills/` discovery do not change. See [Skills](/docs/skills).
+
+### Commands
+
+Rename the singular `command` map to `commands`. Join a separate model `variant` to the model reference:
+
+```jsonc
+// V1
+{
+  "command": {
+    "review": {
+      "template": "Review the current changes.",
+      "model": "anthropic/claude-sonnet-4-5",
+      "variant": "high"
+    }
+  }
+}
+
+// V2
+{
+  "commands": {
+    "review": {
+      "template": "Review the current changes.",
+      "model": "anthropic/claude-sonnet-4-5#high"
+    }
+  }
+}
+```
+
+`template`, `description`, `agent`, and `subtask` keep their names. Existing Markdown command definitions remain supported.
+See [Commands](/docs/commands).
+
+### References
+
+Rename the deprecated singular `reference` map to `references`:
+
+```jsonc
+// V1
+{ "reference": { "docs": "../docs" } }
+
+// V2
+{ "references": { "docs": "../docs" } }
+```
+
+V1 already accepts `references`, so no change is needed when the file uses it. Reference entries keep the
+same shapes. See [References](/docs/references).
+
+### Providers
+
+Rename the singular `provider` map to `providers`. V2 separates the runtime package, endpoint, and request settings:
+
+```jsonc
+// V1
+{
+  "provider": {
+    "acme": {
+      "npm": "@ai-sdk/openai-compatible",
+      "api": "https://llm.example.com/v1",
+      "options": {
+        "apiKey": "{env:ACME_API_KEY}"
+      }
+    }
+  }
+}
+
+// V2
+{
+  "providers": {
+    "acme": {
+      "package": "aisdk:@ai-sdk/openai-compatible",
+      "settings": {
+        "baseURL": "https://llm.example.com/v1",
+        "apiKey": "{env:ACME_API_KEY}"
+      }
+    }
+  }
+}
+```
+
+V1 `npm` becomes `package`, and AI SDK packages receive the `aisdk:` prefix. `api` becomes `settings.baseURL`. Provider
+`options` are separated into `settings`, `headers`, and `body` according to their request role. See [Providers](/docs/providers).
+
+### Models and variants
+
+Models remain nested under their provider, but several model fields become more explicit:
+
+- `id` becomes `modelID`.
+- `tool_call` and `modalities` become `capabilities.tools`, `capabilities.input`, and `capabilities.output`.
+- A `status` of `"deprecated"` becomes `disabled: true`.
+- Cache costs move from `cache_read` and `cache_write` to `cache.read` and `cache.write`.
+- Provider-specific `options` become `settings`.
+- A V1 variants object becomes a V2 array with an `id` on each entry.
+
+```jsonc
+// V1
+{
+  "variants": {
+    "high": {
+      "reasoningEffort": "high"
+    }
+  }
+}
+
+// V2
+{
+  "variants": [
+    {
+      "id": "high",
+      "settings": {
+        "reasoningEffort": "high"
+      }
+    }
+  ]
+}
+```
+
+See [Models](/docs/models) for the complete native model shape.
+
+### Fields without native equivalents
+
+Most fields that keep the same shape, including `shell`, `model`, `default_agent`, `autoupdate`, `watcher`, `formatter`,
+`lsp`, `instructions`, `enterprise`, and `tool_output`, require no migration.
+
+These V1 fields do not have one-to-one native V2 config fields:
+
+- `logLevel`: use `OPENCODE_LOG_LEVEL` when starting OpenCode.
+- `server`: use the V2 service and explicit server options; the server API is an intentional breaking change.
+- `layout`: remove it; V1 already treated it as deprecated and always used stretch layout.
+- `enabled_providers` and `disabled_providers`: there is no native provider allowlist or denylist field yet.
+- `small_model`: V2 selects models for internal maintenance agents without a separate top-level field.
+- `compaction.tail_turns`: V2 uses `compaction.keep.tokens` instead.
+
+If your V1 configuration relies on a field without a native equivalent, keep using the supported V1 format rather than
+forcing a manual conversion. Run `/report` if V2 does not preserve the behavior you rely on.
+
+### Agent files
+
+V1 agent files may use `agent/`, `agents/`, `mode/`, or `modes/`. V2 still discovers all four directories. The preferred
+V2 location is:
+
+```text
+.opencode/agents/<name>.md
+```
+
+Files under a V1 `mode/` or `modes/` directory represent primary agents. When moving one into `agents/`, add
+`mode: primary` to its frontmatter. Files under `agent/` can move to `agents/` without changing their path-derived ID.
+
+When converting the frontmatter to native V2 fields:
+
+- Keep the Markdown body as the agent's system instructions.
+- Rename `prompt` to `system` when it appears in JSON configuration; file bodies do not need a `system` field.
+- Rename `disable` to `disabled` and `permission` to `permissions`.
+- Join `model` and `variant` as `provider/model#variant`.
+- Move `temperature`, `top_p`, and provider-specific options under `request.body`.
+
+V2 translates legacy agent frontmatter automatically, so these edits are optional. See [Agents](/docs/agents).
+
+### Command files
+
+V1 command files may use `command/` or `commands/`. V2 discovers both. The preferred location is:
+
+```text
+.opencode/commands/<name>.md
+```
+
+Move files from `command/` to the same relative path under `commands/` to preserve command names. The Markdown body remains
+the command template, and `description`, `agent`, and `subtask` frontmatter keep the same names. If frontmatter has separate
+`model` and `variant` fields, append the variant to the model and remove `variant`:
+
+```yaml
+# V1
+model: anthropic/claude-sonnet-4-5
+variant: high
+
+# V2
+model: anthropic/claude-sonnet-4-5#high
+```
+
+See [Commands](/docs/commands).
+
+### Skill files
+
+V2 discovers skills from both `.opencode/skill/` and `.opencode/skills/`. The preferred layout is:
+
+```text
+.opencode/skills/<skill-id>/SKILL.md
+```
+
+Move the complete skill directory, not only `SKILL.md`, so relative scripts, references, and other supporting files remain
+available. Keep the directory name stable to preserve the skill ID. Existing skill frontmatter and Markdown bodies do not
+require a V2 rewrite. See [Skills](/docs/skills).
+
+### Instruction files
+
+Existing `AGENTS.md` files stay in place. V2 discovers the global `~/.config/opencode/AGENTS.md` and project `AGENTS.md`
+files from the current directory up to the project root.
+
+If a V1 setup relied on a `CLAUDE.md` fallback, move that guidance into the applicable `AGENTS.md`. V2 currently only
+discovers `AGENTS.md`; because non-API V1 behavior is intended to remain compatible, also run `/report` with the affected
+project details. See [Instructions](/docs/instructions).
+
+## TUI configuration
+
+V1 loaded `tui.json(c)` from the global config directory and from project directories discovered while walking up from
+the current directory. V2 instead stores CLI and TUI settings in one global file:
+
+```text
+~/.config/opencode/cli.json
+```
+
+The CLI owns this file. The background service does not load it, and V2 does not discover or merge project-local
+`tui.json(c)` or `cli.json` files.
+
+The native V2 format groups related settings. For example:
+
+```jsonc
+// V1: ~/.config/opencode/tui.json
+{
+  "theme": "tokyonight",
+  "scroll_speed": 2,
+  "scroll_acceleration": {
+    "enabled": true
+  }
+}
+
+// V2: ~/.config/opencode/cli.json
+{
+  "theme": {
+    "name": "tokyonight"
+  },
+  "scroll": {
+    "speed": 2,
+    "acceleration": true
+  }
+}
+```
+
+V2 migrates the global TUI configuration automatically. On the first CLI or TUI startup, when `cli.json` does not already
+exist, it:
+
+- Reads `~/.config/opencode/tui.json`.
+- Reads persisted TUI preferences from the legacy `kv.json` state file.
+- Converts supported settings to the native grouped format and writes `~/.config/opencode/cli.json`.
+- Leaves the V1 files unchanged so V1 can continue using them.
+
+Migration runs only while `cli.json` is absent. Once that file exists, V2 treats it as the source of truth and does not
+continually synchronize later changes from `tui.json` or `kv.json`. If you created `cli.json` before starting V2, merge any
+V1 settings you still need into it manually.
+
+Project-local V1 TUI configuration is not migrated because V2 has no project-local CLI configuration. Move settings you
+still want into the global `cli.json`; when multiple projects used different values for the same setting, choose the
+global behavior you want V2 to use.
+
+## Plugins
+
+Rename `plugin` to `plugins`. Replace a package-and-options tuple with an object:
+
+```jsonc
+// V1
+{
+  "plugin": [
+    "opencode-example-plugin",
+    ["./plugin/local.ts", { "enabled": true }]
+  ]
+}
+
+// V2
+{
+  "plugins": [
+    "opencode-example-plugin",
+    {
+      "package": "./plugin/local.ts",
+      "options": { "enabled": true }
+    }
+  ]
+}
+```
+
+V2 discovers local plugins from both `.opencode/plugin/` and `.opencode/plugins/`; use `.opencode/plugins/` for V2 files.
+Moving a file between these directories does not migrate its implementation.
+
+<Warning>V1 plugins will not work in V2.</Warning>
+
+The config entry can be translated automatically, but plugin implementation code must be ported to the new API. The V2
+plugin API is still being finalized during beta, and detailed plugin migration guidance will be published when it is
+ready.
+
+Once the V2 plugin API is finalized, OpenCode should be able to migrate the majority of V1 plugins while keeping related
+local modules and dependencies together. See the current beta [Plugins guide](/docs/build/plugins).
+
+## Server API and clients
+
+OpenCode 2 has a revised, more ergonomic server API and a new set of clients. Integrations that call the V1 server API
+must migrate to the V2 API.
+
+Use the `@opencode-ai/client` package to access the new clients. The server API and clients are still being finalized
+during beta, so their contracts may continue to change. See the generated [API reference](/docs/api) for the current endpoints,
+request types, and responses.
+
+## Verify your setup
+
+Start `opencode2` in a project and verify your model, provider credentials, agents, permissions, MCP servers, and plugins
+before relying on the beta for regular work. Keep your V1 setup until you have confirmed the V2 behavior you need, and do
+not point V1 at configuration that you have converted to the native V2 shape.

+title: "Models"
+description: ""
+---
+
+OpenCode builds its model catalog from [Models.dev](https://models.dev), provider integrations, and your configuration.
+Only enabled models whose provider is available for the current project appear in the model picker.
+
+Connect a provider with `/connect` in the TUI, or configure it in [Providers](/docs/providers).
+
+## Choose a model
+
+Open the model picker with `/models` or the default `<leader>m` keybind. The picker shows the models available from
+providers connected to the current project.
+
+Select a model to use it in the current session. Switching models updates that session without changing your config. Use
+the catalog entries shown in the picker rather than guessing a provider or model name.
+
+## Per-run model
+
+Select a model for one non-interactive run with `--model` or `-m`:
+
+```bash
+opencode2 run --model openai/gpt-5.2 "Explain this repository"
+opencode2 run -m openai/gpt-5.2#high "Review the current changes"
+```
+
+Agents and commands can also select their own model. See [Agents](/docs/agents) and [Commands](/docs/commands).
+
+## Variants
+
+Variants are named request overlays for one model, commonly used for reasoning effort or token budgets. Available names
+are model-specific and are derived from current catalog metadata. Do not assume that names such as `low`, `high`, or
+`max` exist for every model; `/variants` shows the valid choices.
+
+Use `/variants` to choose one for the current model, or press `ctrl+t` to cycle through available variants.
+
+## Configure
+
+### Default model
+
+Set `model` in `opencode.json` or `opencode.jsonc`:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "model": "anthropic/claude-sonnet-4-5"
+}
+```
+
+The configured model becomes the catalog default when its provider is available and the model is enabled. Otherwise,
+session execution falls back to the newest available supported model. An explicit model already selected on a session
+takes precedence over the default; switching models changes that session and does not rewrite your config.
+
+See [Config](/docs/config) for configuration locations and precedence.
+
+### Model settings
+
+Provider and model entries can supply three kinds of request configuration:
+
+- `settings` contains provider-package options such as `baseURL`, `reasoningEffort`, or `thinkingConfig`.
+- `headers` adds HTTP request headers.
+- `body` adds provider-specific fields to the request body.
+
+These values are provider-specific JSON. OpenCode applies provider values first, then model values, then the selected
+variant. Nested `settings` and `body` objects are merged; later array and scalar values replace earlier values. Header
+names are matched case-insensitively.
+
+You can also map a friendly catalog ID to a different API model ID with `modelID`:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "model": "openai/coding-default",
+  "providers": {
+    "openai": {
+      "models": {
+        "coding-default": {
+          "modelID": "gpt-5.2",
+          "name": "Coding default",
+          "capabilities": {
+            "tools": true,
+            "input": ["text", "image"],
+            "output": ["text"]
+          },
+          "limit": {
+            "context": 200000,
+            "output": 32000
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+Here `openai/coding-default` is the selectable catalog reference, while `gpt-5.2` is sent to the provider. When adding a
+model that is not already in the catalog, set accurate `capabilities` and `limit` values so OpenCode can expose tools and
+enforce the correct context limits. Set `disabled: true` on a model entry to hide it from the available catalog.
+
+### Custom variants
+
+Add a variant, or override a catalog variant with the same ID, under the model's `variants` array:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "providers": {
+    "openai": {
+      "models": {
+        "gpt-5.2": {
+          "settings": {
+            "reasoningEffort": "medium"
+          },
+          "variants": [
+            {
+              "id": "fast",
+              "settings": {
+                "reasoningEffort": "low"
+              }
+            },
+            {
+              "id": "deep",
+              "settings": {
+                "reasoningEffort": "high",
+                "reasoningSummary": "auto"
+              }
+            }
+          ]
+        }
+      }
+    }
+  }
+}
+```
+
+Variant entries support `settings`, `headers`, and `body`. Selecting one deeply overlays its values on the effective
+provider and model configuration. An unknown variant fails model resolution instead of silently using the base model.
+
+### Local models
+
+For an OpenAI-compatible server, define a provider package, endpoint, and at least one model:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "model": "local/coder",
+  "providers": {
+    "local": {
+      "name": "Local server",
+      "package": "aisdk:@ai-sdk/openai-compatible",
+      "settings": {
+        "baseURL": "http://127.0.0.1:1234/v1"
+      },
+      "models": {
+        "coder": {
+          "modelID": "model-name-on-server",
+          "capabilities": {
+            "tools": true,
+            "input": ["text"],
+            "output": ["text"]
+          },
+          "limit": {
+            "context": 32768,
+            "output": 8192
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+Use the server's real model name, limits, modalities, and tool support. OpenCode cannot infer these for a model you add
+manually. If the endpoint requires a key, add `apiKey` to provider `settings` using an environment substitution such as
+`"apiKey": "{env:LOCAL_API_KEY}"`; do not commit secrets.
+
+### Model references
+
+Configuration and CLI options identify a model as `provider/model`, with an optional `#variant`:
+
+```text
+openai/gpt-5.2
+openai/gpt-5.2#high
+openrouter/anthropic/claude-sonnet-4.5#high
+```
+
+OpenCode splits the reference at the first `/`, so model IDs may contain additional slashes. Provider and model IDs are
+case-sensitive. Provider IDs cannot contain `/` or `#`, and model IDs cannot contain `#`.
+
+The expanded config form is equivalent when generated or programmatic configuration is more convenient:
+
+```jsonc
+{
+  "model": {
+    "providerID": "openrouter",
+    "model": "anthropic/claude-sonnet-4.5"
+  }
+}
+```
+
+Root, agent, and command `model` fields accept both forms. Use the IDs shown by `/models`, not provider display names.
+
+### Caveats
+
+- The selector object uses `model`, while a provider catalog entry uses `modelID` for the upstream API identifier.
+- The root `model` currently sets the default provider and model only. Although its selection shape accepts a variant,
+  the V2 catalog default does not retain it; select a variant in the TUI, with `opencode2 run`, or on an agent or command.
+- Model options are provider-specific. A setting accepted by one provider package may be ignored or rejected by another.
+- Catalog data, credentials, and config are location-scoped. A model available in one project may be unavailable in
+  another.
+- Configuration files are watched and normally reload automatically, but an in-flight model request keeps the settings
+  with which it started.

+description: ""

+
+Permissions control whether an agent may perform an action on a resource. V2
+configuration uses the `permissions` field and an ordered array of rules.
+
+<Warning>
+  The V1 object syntax uses different field and action names. Do not use
+  `permission`, `bash`, or `task` in V2 configuration; use `permissions`,
+  `shell`, and `subagent`.
+</Warning>
+
+## Rule schema
+
+Each rule has three required string fields:
+
+```jsonc
+{
+  "$schema": "https://opencode.ai/config.json",
+  "permissions": [
+    { "action": "*", "resource": "*", "effect": "ask" },
+    { "action": "read", "resource": "*", "effect": "allow" },
+    { "action": "read", "resource": "*.env", "effect": "deny" },
+    { "action": "shell", "resource": "git status *", "effect": "allow" },
+    { "action": "shell", "resource": "git push *", "effect": "deny" },
+    { "action": "edit", "resource": "packages/docs/*.mdx", "effect": "allow" }
+  ]
+}
+```
+
+- `action` matches a tool permission action.
+- `resource` matches the value the tool is trying to use, such as a path,
+  command, URL, query, or agent ID.
+- `effect` is `"allow"`, `"deny"`, or `"ask"`.
+
+`allow` proceeds without prompting, `deny` blocks the operation, and `ask`
+waits for a user decision. If no rule matches, the result is `ask`.
+
+## Matching and order
+
+Both `action` and `resource` support simple wildcards:
+
+- `*` matches zero or more characters, including `/`.
+- `?` matches exactly one character.
+- All other characters are literal.
+
+Matches cover the entire value. Slashes are normalized, and matching is
+case-insensitive on Windows. For shell convenience, a pattern ending in
+`" *"` also matches the command without arguments: `"git status *"` matches
+both `git status` and `git status --short`.
+
+The **last matching rule wins**. Put broad rules first and exceptions later.
+Rules from lower-priority configuration files are loaded first. OpenCode then
+appends all global rules before agent-specific rules, so a matching agent rule
+overrides a global rule.
+
+Some operations check several resources at once, such as a patch touching
+multiple files. OpenCode denies the operation if any resource resolves to
+`deny`; otherwise it asks if any resolves to `ask`; otherwise it allows it.
+
+## Actions and resources
+
+V2 action names are strings, so plugins may introduce additional actions. The
+current built-in actions use these resources:
+
+| Action | Resource matched |
+| --- | --- |
+| `read` | Location-relative path for an internal file or directory; canonical absolute path for an external target |
+| `edit` | Target path for `edit`, `write`, and `patch`; all three tools share this action |
+| `glob` | The requested glob pattern |
+| `grep` | The requested regular expression, not the search path |
+| `shell` | The complete raw shell command string |
+| `subagent` | The target agent ID |
+| `skill` | The skill ID |
+| `question` | `*` |
+| `webfetch` | The requested URL |
+| `websearch` | The search query |
+| `external_directory` | A canonical external directory boundary, normally ending in `/*` |
+| `<server>_<tool>` | `*` for an MCP tool; unsupported characters in both names become `_` |
+| `execute` | `*`; controls availability of the Code Mode dispatcher, while each nested tool still enforces its own permission |
+
+Built-in agent policy also reserves `plan_enter` and `plan_exit` for plan-mode
+transitions. `doom_loop` and `lsp` are not current V2 Core permission actions.
+
+## External directories
+
+An external path requires a separate `external_directory` decision before the
+tool's own `read` or `edit` decision. This applies to external paths used by
+`read`, `edit`, `write`, and `patch`, and to an external `shell` working
+directory.
+
+```jsonc
+{
+  "$schema": "https://opencode.ai/config.json",
+  "permissions": [
+    {
+      "action": "external_directory",
+      "resource": "~/projects/reference/*",
+      "effect": "allow"
+    },
+    {
+      "action": "read",
+      "resource": "~/projects/reference/*",
+      "effect": "allow"
+    },
+    {
+      "action": "edit",
+      "resource": "~/projects/reference/*",
+      "effect": "deny"
+    }
+  ]
+}
+```
+
+For `external_directory`, `read`, and `edit` resources, a leading `~`, `~/`,
+`$HOME`, or `$HOME/` is expanded when configuration loads. Shell resources are
+raw command text and are **not** home-expanded.
+
+<Warning>
+  `shell` runs with the host user's filesystem, process, and network authority.
+  Its resource is raw text, not a parsed command. External command arguments
+  produce only best-effort warnings; `external_directory` is enforced for the
+  working directory, not every path embedded in a command. Prefer a narrow
+  shell allowlist over patterns intended to identify every dangerous command.
+</Warning>
+
+Relative mutation paths cannot escape the active Location, and symlink escapes
+from inside it are rejected. Explicit external paths are canonicalized before
+matching, so authorize only trusted directory boundaries.
+
+## Defaults
+
+The evaluator's fallback is `ask`, but shipped agents include ordered defaults:
+
+| Agent | Effective default policy |
+| --- | --- |
+| `build` | Allows most actions; asks for external directories and `.env` reads; allows questions and entering plan mode; denies exiting plan mode |
+| `plan` | Uses the same base, allows questions and exiting plan mode, and denies edits except OpenCode plan files |
+| `general` | Uses the base policy but cannot launch another subagent; questions and plan transitions remain denied |
+| `explore` | Denies everything except `read`, `glob`, `grep`, `webfetch`, and `websearch`; cannot launch subagents and asks for external directories |
+| Hidden maintenance agents | Deny all actions |
+
+The base read rules are ordered as follows:
+
+```jsonc
+[
+  { "action": "read", "resource": "*", "effect": "allow" },
+  { "action": "read", "resource": "*.env", "effect": "ask" },
+  { "action": "read", "resource": "*.env.*", "effect": "ask" },
+  { "action": "read", "resource": "*.env.example", "effect": "allow" }
+]
+```
+
+OpenCode also permits its managed tool-output and temporary directories where
+needed. These exceptions do not grant general external-directory access.
+
+## Agent overrides
+
+Configure shared policy at the top level and append narrower rules to a named
+agent under `agents.<id>.permissions`:
+
+```jsonc
+{
+  "$schema": "https://opencode.ai/config.json",
+  "permissions": [
+    { "action": "shell", "resource": "*", "effect": "ask" },
+    { "action": "shell", "resource": "git diff *", "effect": "allow" },
+    { "action": "shell", "resource": "git status *", "effect": "allow" }
+  ],
+  "agents": {
+    "reviewer": {
+      "description": "Review code without changing it",
+      "mode": "subagent",
+      "permissions": [
+        { "action": "edit", "resource": "*", "effect": "deny" },
+        { "action": "shell", "resource": "git diff *", "effect": "allow" },
+        { "action": "shell", "resource": "git status *", "effect": "allow" }
+      ]
+    }
+  }
+}
+```
+
+Agent rules do not replace the global array; they are appended after it. A
+custom subagent executes with its own permissions, not a permission subset
+derived from the parent agent.
+
+## Approval choices
+
+When an `ask` rule matches, clients can reply with:
+
+- **Allow once** (`once`): approve only the pending request.
+- **Allow always** (`always`): approve this request and save the patterns
+  proposed by the tool for the current project.
+- **Reject** (`reject`): reject the request. Rejecting also rejects other
+  pending permission requests in the same session; clients may attach feedback.
+
+Saved approvals are durable and project-scoped. They are additional `allow`
+rules, but they can never override a configured `deny`. The proposed saved
+pattern may be broader than the displayed resource: several tools propose `*`,
+shell proposes the exact command text, and skills and subagents propose their
+IDs. Review the confirmation carefully and remove saved approvals that are no
+longer needed.
+
+For non-interactive runs, `opencode2 run --auto` replies `once` to permission
+requests. It does not save approvals, and explicit `deny` rules remain enforced.
+Without `--auto`, a non-interactive run rejects permission requests.

+title: "Providers"
+description: ""
+---
+
+OpenCode builds its provider and model catalog from [Models.dev](https://models.dev), then applies the `providers`
+overlays from your [configuration](/docs/config). A provider needs both a usable runtime package and, when required, an
+active connection.
+
+## Connect a provider
+
+Run `/connect` in the TUI, choose an integration, and complete one of the methods it offers:
+
+```text
+/connect
+```
+
+An integration may support an API key, OAuth, environment variables, or a combination of them. API keys and OAuth
+tokens entered through `/connect` are stored by the OpenCode service in its database. Run `/connect` again to replace
+or remove a stored credential.
+
+Providers from Models.dev also declare their standard environment variables. A non-empty declared variable is exposed
+as an environment connection automatically, so common providers usually need no config:
+
+```bash
+export ANTHROPIC_API_KEY="your-key"
+```
+
+For a custom provider, `env` declares the variables that can supply its key:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "providers": {
+    "acme": {
+      "env": ["ACME_API_KEY"]
+    }
+  }
+}
+```
+
+When several credential sources exist, OpenCode uses the stored credential first, then the first non-empty variable in
+`env`, then `settings.apiKey`. Use config substitution instead of committing a literal key:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "providers": {
+    "acme": {
+      "settings": {
+        "apiKey": "{env:ACME_API_KEY}"
+      }
+    }
+  }
+}
+```
+
+<Warning>Do not commit API keys or authorization headers to your repository.</Warning>
+
+## Configure
+
+The `providers` object is keyed by provider ID. Each provider accepts these fields:
+
+| Field | Purpose |
+| --- | --- |
+| `name` | Display name. |
+| `env` | Ordered environment variable names that provide a connection. |
+| `package` | Runtime provider package. |
+| `settings` | JSON settings passed to the runtime package, such as `baseURL`. |
+| `headers` | String-valued HTTP headers added to requests. |
+| `body` | JSON fields merged into request bodies. |
+| `models` | Models to add or override, keyed by catalog model ID. |
+
+Configuration files are applied from lowest to highest precedence. `settings` and `body` are deep-merged. Headers are
+merged case-insensitively. At request time, provider values are inherited by the model, model values override them, and
+the selected variant is applied last.
+
+### Endpoint
+
+Override `settings.baseURL` to send an existing provider through a proxy or compatible endpoint. Its existing package,
+models, and connection continue to apply:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "providers": {
+    "anthropic": {
+      "settings": {
+        "baseURL": "https://llm-proxy.example.com/anthropic"
+      }
+    }
+  }
+}
+```
+
+`settings` is package-specific. A field only has an effect when the selected package supports it.
+
+### Headers and body
+
+Headers and body fields can be set at provider, model, or variant scope:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "providers": {
+    "openai": {
+      "headers": {
+        "X-Gateway-Tenant": "engineering"
+      },
+      "body": {
+        "metadata": {
+          "application": "opencode"
+        }
+      },
+      "models": {
+        "gpt-5.2": {
+          "headers": {
+            "X-Model-Policy": "coding"
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+These are request overlays, not a generic authentication scheme. Prefer `/connect`, `env`, or `settings.apiKey` for
+provider credentials unless the endpoint explicitly requires a custom header.
+
+### Provider packages
+
+For an OpenAI-compatible service, use the V2 native compatible package. The model map is explicit because a custom
+provider has no Models.dev catalog entries:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "model": "acme/qwen3-coder",
+  "providers": {
+    "acme": {
+      "name": "Acme Gateway",
+      "env": ["ACME_API_KEY"],
+      "package": "@opencode-ai/llm/providers/openai-compatible",
+      "settings": {
+        "baseURL": "https://llm.acme.example/v1"
+      },
+      "models": {
+        "qwen3-coder": {
+          "name": "Qwen 3 Coder",
+          "capabilities": {
+            "tools": true,
+            "input": ["text"],
+            "output": ["text"]
+          },
+          "limit": {
+            "context": 131072,
+            "output": 32768
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+Omit `env` for an endpoint that does not require authentication. The native compatible package requires
+`settings.baseURL` and uses bearer authentication when a key is available.
+
+The `package` field supports two runtime contracts:
+
+| Form | Contract |
+| --- | --- |
+| `"@opencode-ai/llm/providers/openai-compatible"` | A V2 native package exporting `model(modelID, settings)`. An npm specifier or absolute `file://` URL may use the same contract. |
+| `"aisdk:@ai-sdk/openai-compatible"` | An AI SDK provider package. The `aisdk:` prefix is required. |
+
+Native packages receive the merged `settings` plus the resolved `apiKey`, `headers`, `body`, and `limits`. AI SDK
+packages receive their merged provider options. Use a package's own documentation for accepted settings; OpenCode does
+not validate package-specific keys.
+
+`package` may also be set on one model to override the provider package for that model.
+
+### Models
+
+Add a model under a provider's `models` map. The object key is the model ID used in OpenCode; `modelID` is the ID sent to
+the provider:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "model": "openai/coding",
+  "providers": {
+    "openai": {
+      "models": {
+        "coding": {
+          "modelID": "gpt-5.2",
+          "name": "GPT-5.2 Coding"
+        }
+      }
+    }
+  }
+}
+```
+
+See [Models](/docs/models) for model selection, defaults, capabilities, limits, costs, and variants.

+---
+title: "References"
+description: ""
+---
+
+References give OpenCode named access to directories outside the current
+project. Use them for documentation, shared libraries, examples, or source from
+another repository.
+
+Configure references by alias in `opencode.json` or `opencode.jsonc`:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "references": {
+    "docs": {
+      "path": "../product-docs",
+      "description": "Use for product behavior and terminology"
+    },
+    "effect": {
+      "repository": "Effect-TS/effect",
+      "branch": "main",
+      "description": "Use for Effect implementation details"
+    }
+  }
+}
+```
+
+## Local directories
+
+Use `path` for a local directory:
+
+```jsonc
+{
+  "references": {
+    "design-system": {
+      "path": "../design-system",
+      "description": "Use when working with components or design tokens"
+    }
+  }
+}
+```
+
+Relative paths resolve from the directory containing the config file that
+defines them. Absolute paths and home-relative paths such as `~/docs` are also
+supported.
+
+The string shorthand is useful when no other fields are needed:
+
+```jsonc
+{
+  "references": {
+    "docs": "../docs",
+    "shared": "~/work/shared"
+  }
+}
+```
+
+<Note>
+  A shorthand string is treated as a local path only when it starts with `.`,
+  `/`, or `~`. Use `./docs`, not `docs`; a bare `docs` value is interpreted as
+  a Git repository.
+</Note>
+
+## Git repositories
+
+Use `repository` for a remote Git repository. GitHub `owner/repo` shorthand,
+Git URLs, host/path forms, and SCP-style remotes are supported.
+
+```jsonc
+{
+  "references": {
+    "effect": {
+      "repository": "Effect-TS/effect",
+      "branch": "main"
+    },
+    "internal-sdk": {
+      "repository": "git@gitlab.example.com:platform/sdk.git",
+      "branch": "release/v2"
+    }
+  }
+}
+```
+
+Without `branch`, OpenCode checks out and refreshes the remote's default
+branch. Branch names may contain letters, numbers, `/`, `_`, `.`, and `-`, but
+cannot start with `-` or contain `..`. Local `file:` repositories are not
+supported.
+
+Git references also support shorthand:
+
+```jsonc
+{
+  "references": {
+    "effect": "Effect-TS/effect",
+    "sdk": "gitlab.com/platform/sdk"
+  }
+}
+```
+
+### Cloning and storage
+
+OpenCode normalizes a remote and stores one checkout under its global data
+directory at `opencode/repos/<host>/<repository-path>`. On a typical Linux
+installation, for example, `Effect-TS/effect` is stored at:
+
+```text
+~/.local/share/opencode/repos/github.com/Effect-TS/effect
+```
+
+Missing repositories are cloned. Existing checkouts are fetched and reset to
+the requested branch, or to the remote default branch when `branch` is omitted.
+Materialization runs asynchronously when references load or reload, so a new
+reference can appear before its checkout is ready. Clone and refresh failures
+are logged and do not stop other references from loading.
+
+<Warning>
+  The cache has one checkout per normalized remote, not one per branch. Do not
+  configure the same repository at multiple branches; only one branch can be
+  exposed. Avoid editing cached checkouts because a refresh resets them.
+</Warning>
+
+## Description and visibility
+
+`description` tells agents when a reference is relevant. References with a
+description are included in agent instructions with their alias and resolved
+path. References without one remain available in `@` autocomplete but are not
+advertised automatically.
+
+Set `hidden` to `true` to remove a reference from TUI `@` autocomplete:
+
+```jsonc
+{
+  "references": {
+    "internal": {
+      "path": "../internal",
+      "description": "Use for internal service behavior",
+      "hidden": true
+    }
+  }
+}
+```
+
+`hidden` controls only autocomplete visibility. It does not remove the
+reference from the reference API or agent instructions when a description is
+present.
+
+## Use references
+
+Type `@` in the TUI and select a reference alias to attach its root directory:
+
+```text
+Compare the current implementation with @effect
+```
+
+The attachment provides a non-recursive listing of the root's immediate files
+and directories. V2 currently attaches references by root alias;
+`@alias/path` is not a reference-specific file browser. Ask the agent to
+inspect a particular path when more detail is needed.
+
+References do not grant extra tool permissions. Access outside the active
+Location remains subject to the agent's normal tool rules and the
+`external_directory` permission. Editing a reference additionally requires the
+applicable edit permission.
+
+## Fields
+
+| Field | Local | Git | Description |
+| --- | --- | --- | --- |
+| `path` | Required | No | Local directory path |
+| `repository` | No | Required | Remote Git repository |
+| `branch` | No | Optional | Branch to fetch and check out |
+| `description` | Optional | Optional | Guidance describing when agents should use it |
+| `hidden` | Optional | Optional | Hide it from TUI `@` autocomplete |
+
+An alias cannot be empty or contain `/`, `\`, whitespace, a backtick, or a
+comma.

+Skills are Markdown instructions that OpenCode can advertise to an agent and
+load when they are relevant. A skill can include supporting scripts,
+references, and other files in the same directory.
+
+## Create a skill
+
+Create one directory per skill with a `SKILL.md` file:
+
+```text
+.opencode/skills/
+└── git-release/
+    ├── SKILL.md
+    ├── scripts/
+    │   └── changelog.ts

+---
+name: Git Release
+description: Prepare release notes, version bumps, and GitHub releases
+metadata:
+  opencode/slash: "true"
+---
+
+## Workflow
+
+1. Read `references/release-policy.md`.
+2. Summarize merged changes since the previous tag.
+3. Propose the version bump before changing files.
+4. Run `scripts/changelog.ts` only after the user approves the version.
+```
+
+Paths in a skill are relative to the directory containing `SKILL.md`.
+
+## Discovery
+
+OpenCode automatically adds the following source directories:
+
+| Scope | Sources |
+| --- | --- |
+| Global | `~/.config/opencode/skills` |
+| Global compatibility | `~/.claude/skills`, `~/.agents/skills` |
+| Project | `.opencode/skills` |
+| Project compatibility | `.claude/skills`, `.agents/skills` |
+
+For project sources, OpenCode searches from the current directory upward to
+the project root and includes matching directories at every level.
+
+Within each source directory, OpenCode discovers:
+
+- Markdown files at the source root, such as `skills/git-release.md`
+- `SKILL.md` files at any depth, such as `skills/git-release/SKILL.md`
+
+The directory form is recommended because it gives the skill a private base
+directory for supporting files.
+
+## Configure sources
+
+Use the `skills` array in any `opencode.json` or `opencode.jsonc` to add local
+directories or HTTP catalogs:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "skills": [
+    "./team-skills",
+    "~/shared/opencode-skills",
+    "/opt/company-skills",
+    "https://example.com/opencode/skills/"
+  ]
+}
+```
+
+Relative paths are resolved from the active OpenCode working directory, not
+from the directory containing the config file. Paths beginning with `~/` use
+the current user's home directory. Only `http://` and `https://` values are
+treated as URL sources.
+
+Every discovered config document contributes its `skills` entries; the arrays
+are additive rather than replacing one another.
+
+### HTTP catalogs
+
+An HTTP source is a base URL containing an `index.json`:
+
+```json title="index.json"
+{
+  "skills": [
+    {
+      "name": "git-release",
+      "version": "3",
+      "files": [
+        "git-release.md",
+        "references/release-policy.md"
+      ]
+    }
+  ]
+}
+```
+
+OpenCode downloads those files from
+`<base-url>/git-release/<file>`. File paths must be safe, relative,
+same-origin paths. Each entry must include either `SKILL.md` or a Markdown file
+named after the index entry, such as `git-release.md`.
+
+Use the named Markdown form for HTTP catalogs. Each downloaded skill directory
+is itself a source root, so `git-release.md` produces the ID `git-release`; a
+root-level `SKILL.md` produces the literal ID `SKILL` in the current V2
+implementation. Increment `version` when files change so OpenCode refreshes
+the cached copy.
+
+## Frontmatter
+
+V2 reads these fields:
+
+| Field | Purpose |
+| --- | --- |
+| `name` | Display name; defaults to the path-derived ID |
+| `description` | Summary shown to the model and command catalog |
+| `slash` | Set to `false` to hide the skill from the V2 slash-command catalog |
+| `metadata.opencode/slash` | Boolean or `"true"`/`"false"`; overrides `slash` |
+| `metadata.opencode/autoinvoke` | Set to `false` to omit the skill from model-facing discovery |
+
+Frontmatter, `name`, and `description` are optional at runtime. However, a
+clear `description` is strongly recommended: skills without one are not
+advertised to the model. `license`, `compatibility`, and other metadata may be
+included for portability, but V2 does not interpret them.
+
+`opencode/autoinvoke: false` only removes the skill from the model's available
+skills list. The skill remains registered and can still be activated explicitly
+by its ID.
+
+## IDs and validation
+
+The skill ID comes from its path, not its frontmatter:
+
+| File | ID |
+| --- | --- |
+| `<source>/git-release.md` | `git-release` |
+| `<source>/git-release/SKILL.md` | `git-release` |
+| `<source>/teams/release/SKILL.md` | `release` |
+
+IDs are exact and case-sensitive. V2 currently does not enforce the Agent
+Skills name regex, length limits, a match between `name` and the directory, or
+a maximum description length. The frontmatter `name` is only a display label.
+
+For portable, predictable skills, use a unique lowercase kebab-case ID of 1-64
+characters and keep it aligned with the directory name:
+
+```text
+^[a-z0-9]+(-[a-z0-9]+)*$
+```
+
+## Precedence
+
+Skills are keyed by ID. If several sources define the same ID, the later source
+wins. Sources are registered in this order, from lower to higher precedence:
+
+1. Built-in skills
+2. `.claude/skills` sources, global first and then from the current directory upward
+3. `.agents/skills` sources, global first and then from the current directory upward
+4. `~/.config/opencode/skills`
+5. Project `.opencode/skills`, from the project root toward the current directory
+6. Explicit `skills` config entries, in config priority and array order
+
+Avoid duplicate IDs unless an override is intentional.
+
+## Runtime loading
+
+At each model step, OpenCode advertises permitted skills that have a
+description and do not set `opencode/autoinvoke` to `false`. The advertisement
+contains only each skill's ID, name, and description; it does not add every
+skill body to the prompt.
+
+When the model calls the `skill` tool with an exact ID, OpenCode:
+
+1. Resolves the current winning definition for that ID
+2. Checks the `skill` permission for the selected agent
+3. Adds the Markdown body, without frontmatter, to the conversation
+4. Provides the skill's base directory and a sample of up to ten supporting file paths
+
+Supporting file contents are not loaded automatically. The agent can read a
+referenced file when the skill instructs it to do so. The supporting-file
+sample is available for directory-based `SKILL.md` skills; flat Markdown skills
+receive no neighboring file list.
+
+In the V2 CLI, skills appear as `/id` commands unless `slash` resolves to
+`false`. Selecting one appends the skill body as a skill message and resumes
+the session.
+
+## Permissions
+
+Permission rules use the `skill` action and the skill ID as the resource. Rules
+are evaluated in order, with the last matching rule winning:
+
+```jsonc title="opencode.jsonc"
+{
+  "permissions": [
+    { "action": "skill", "resource": "*", "effect": "allow" },
+    { "action": "skill", "resource": "internal-*", "effect": "deny" },
+    { "action": "skill", "resource": "experimental-*", "effect": "ask" }
+  ]
+}
+```
+
+`deny` removes matching skills from model-facing discovery and rejects skill
+tool loading. `ask` advertises the skill but requests approval when the model
+loads it. The same rules can be placed under an individual
+`agents.<id>.permissions` array.
+
+## Troubleshooting
+
+If a skill is missing or loads the wrong content:
+
+1. Confirm the file is either a root-level `*.md` or a nested file named exactly `SKILL.md`.
+2. Check the path-derived ID rather than the frontmatter `name`.
+3. Add a `description` if the skill should be advertised to the model.
+4. Check `opencode/autoinvoke` and the selected agent's `skill` permissions.
+5. Look for a later source defining the same ID.
+6. For HTTP catalogs, verify `index.json`, same-origin file paths, and a changed `version`.

+title: "Undo"
+description: ""
+---
+
+OpenCode snapshots let the default interactive TUI roll back conversation history and related file changes. They are a
+convenience for revising recent work, not a replacement for Git commits or backups.
+
+## Configuration
+
+Snapshots are enabled by default. Set `snapshots` to `false` in your [configuration](/docs/config#snapshots) to stop capturing
+filesystem state:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "snapshots": false
+}
+```
+
+Filesystem snapshots require a Git repository. With snapshots disabled, unavailable, or missing, undo can still stage a
+conversation rollback, but it has no captured file state to restore. Disabling snapshots does not delete snapshots that
+were already stored.
+
+## What is captured
+
+For each model step, OpenCode attempts to capture the worktree immediately before the model call and after a cleanly
+completed step. It records the paths changed between those two points on the assistant message.
+
+Snapshots use a separate internal Git object database in the OpenCode data directory. They do not create commits, move
+branches, or intentionally modify your repository's Git index. Capture is limited to the session's active directory, which
+may be a subdirectory of the repository.
+
+Within that directory, snapshots include tracked files and untracked files that are not ignored by Git. An individual
+untracked file larger than 2 MiB is excluded. Ignored files, files outside the active directory, and changes to Git
+metadata are not captured.
+
+During undo, OpenCode does not check out an entire tree. It restores only paths attributed to cleanly completed assistant
+steps after the selected conversation boundary. Each path is restored to its state before the first affected step.
+
+## Undo
+
+Wait for the session to become idle, then run:
+
+```text
+/undo
+```
+
+The TUI finds the latest non-empty user message and stages a revert at that message:
+
+- The selected user message and every later message are hidden, but not deleted yet.
+- The selected message's text, attachments, and agent mentions are placed in the composer for revision.
+- Captured files changed by the affected assistant steps are restored to their earlier contents. Files created by those
+  steps are removed when they did not exist in the earlier snapshot.
+- A summary shows the staged message count and restored paths.
+
+Running `/undo` again moves the staged boundary to an earlier user message. OpenCode keeps the filesystem state from
+immediately before the first undo as the redo baseline, so repeated undos form one wider staged revert rather than a redo
+stack.
+
+<Warning>
+  Sending a new prompt while an undo is staged commits the revert. The hidden message range is removed from the active
+  session history, the currently reverted files are kept, and redo is no longer available.
+</Warning>
+
+## Redo
+
+While a revert is staged, run:
+
+```text
+/redo
+```
+
+Redo clears the staged boundary, makes the hidden messages visible again, and restores affected files to their exact state
+immediately before the first undo. It does not rerun the model. After multiple undos, one redo restores the whole staged
+range; there is no step-by-step redo stack.
+
+## Revert a message
+
+The TUI's **Message Actions** menu also provides **Revert**. It stages the selected message as the conversation boundary
+and uses the same file restoration and redo behavior, but it does not copy that message into the composer.
+
+For a conversation-and-files rollback, select a user message. If an assistant message is selected, that message is hidden,
+but only file changes attributed to later assistant steps are restored; the selected assistant message's own file changes
+are not included.
+
+## Limitations and safety
+
+- Capture is best effort. A failed capture is logged and the model step continues, so conversation rollback may have no
+  matching file rollback.
+- Interrupted or failed steps do not receive a completed end snapshot. File changes made before the failure may remain.
+- Shell commands can change databases, services, processes, network resources, Git state, ignored build output, or files
+  outside the active directory. Undo and redo do not reverse those side effects.
+- Undo overwrites the current contents of affected paths with older contents. Redo likewise overwrites those paths with
+  the pre-undo state, including edits made after running undo.
+- Other processes can edit the worktree between capture and restore. The server rejects revert operations while the
+  session is actively running, but it cannot protect against external editors or commands.
+- Snapshot objects can contain complete contents of tracked and non-ignored untracked files. They are stored locally in
+  the OpenCode data directory; do not treat snapshots as secret-free metadata.
+- Undo is not secure erasure. Committing a revert removes messages from the active projection, not from durable session
+  history or existing snapshot storage.
+
+Review the staged file summary and your Git diff before continuing. Commit or back up important work independently before
+using undo on a dirty worktree.
+
+<Note>
+  `/undo` and `/redo` are interactive TUI commands. The non-interactive `run` command does not provide them.
+</Note>

+title: "Troubleshooting"
+description: "Diagnose OpenCode startup, server, and session issues."
+---
+
+<Tip>
+  You can ask OpenCode to debug itself. Describe the problem and ask it to use this troubleshooting page; it can read the
+  steps below, inspect its service and logs, and help identify the issue.
+</Tip>
+
+OpenCode runs as two processes: the TUI is a client, while a background server owns sessions, plugins, permissions, and
+other application state. Start by determining whether an issue is in the client, the shared server, or a specific project.
+
+## Check the background service
+
+Show the current server status:
+
+```bash
+opencode2 service status
+```
+
+Verify that its API is healthy:
+
+```bash
+opencode2 api get /api/health
+```
+
+If the service is stuck or unhealthy, restart it:
+
+```bash
+opencode2 service restart
+```
+
+From inside the TUI, run `/reload` to restart the managed service and reconnect:
+
+```text
+/reload
+```
+
+You can also stop and start it explicitly:
+
+```bash
+opencode2 service stop
+opencode2 service start
+```
+
+<Note>
+  OpenCode normally discovers or starts the shared background service automatically. The service commands are only needed
+  when diagnosing its lifecycle.
+</Note>
+
+## Run an isolated session
+
+Use standalone mode to run the TUI with a private server that exits with it:
+
+```bash
+opencode2 --standalone
+```
+
+If an issue disappears in standalone mode, it is likely related to the shared background service rather than the TUI or
+project itself.
+
+## Inspect the API
+
+The `api` command uses the same discovery and authentication flow as the TUI. It accepts either an HTTP method and path or
+an OpenAPI operation ID.
+
+See the [API reference](/docs/api) for all endpoints and operation IDs.
+
+Pass a JSON request body with `--data` or `-d`, and add headers with `--header` or `-H`.
+
+<Warning>
+  Running `opencode2 api` may start the background service when no compatible healthy service is available.
+</Warning>
+
+## Read logs
+
+Installed builds write logs to:
+
+```text
+~/.local/share/opencode/log/opencode.log
+```
+
+Follow the log while reproducing the problem:
+
+```bash
+tail -f ~/.local/share/opencode/log/opencode.log
+```
+
+Each line includes a process `run` ID and a `role` field. Use `role=cli` for TUI and command startup, and `role=server` for
+session, provider, plugin, permission, and tool activity.
+
+```bash
+grep 'role=cli' ~/.local/share/opencode/log/opencode.log
+grep 'role=server' ~/.local/share/opencode/log/opencode.log
+grep 'run=8fc3b1d5' ~/.local/share/opencode/log/opencode.log
+```
+
+Increase verbosity for one reproduction:
+
+```bash
+OPENCODE_LOG_LEVEL=DEBUG opencode2
+```
+
+## Service files
+
+The shared server registers itself at:
+
+```text
+~/.local/state/opencode/service.json
+```
+
+Its private service configuration is stored separately at:
+
+```text
+~/.config/opencode/service.json
+```
+
+The database normally lives at:
+
+```text
+~/.local/share/opencode/opencode-next.db
+```
+
+`OPENCODE_DB` can override the database location.
+
+<Warning>
+  Do not delete or edit service files or the database while troubleshooting. Use the service commands to manage the daemon,
+  and make a backup before inspecting persistent data with external tools.
+</Warning>
+
+## Explicit servers
+
+When connecting with `--server`, set `OPENCODE_PASSWORD` if the server requires authentication:
+
+```bash
+OPENCODE_PASSWORD=secret opencode2 --server http://127.0.0.1:4096
+```
+
+The CLI checks the server before opening the TUI and reports whether it is unreachable, requires a password, or rejected
+the supplied password.
+
+## Report an issue
+
+Include the following when reporting a reproducible problem:
+
+- Output from `opencode2 --version`
+- Output from `opencode2 service status`
+- The smallest sequence of steps that reproduces the issue
+- Whether the issue also occurs with `opencode2 --standalone`
+- Relevant log lines, including their `run` and `role` fields
+
+Remove API keys, authorization headers, prompts, file contents, and other sensitive data before sharing logs.
+
+## Local development
+
+When working from the OpenCode repository, run V2 commands from the repository root:
+
+```bash
+bun dev
+```
+
+The local development channel keeps its logs, SQLite database, and service registration separate from installed builds:
+
+```text
+~/.local/share/opencode/log/opencode-local.log
+~/.local/share/opencode/opencode-local.db
+~/.local/state/opencode/service-local.json
+```
+
+Use the same diagnostics through the package development command:
+
+```bash
+bun dev service status
+bun dev service restart
+bun dev api get /api/health
+```

+`@opencode-ai/client` is the generated TypeScript client for the OpenCode HTTP
+API. Use it when your application connects to an OpenCode server over the
+network. Its types and methods are generated from the same contract as the
+[API reference](/docs/api).
+
+<Warning>
+  The V2 API and client are beta. Method names, inputs, and outputs may change
+  before the stable release.
+</Warning>
+
+## Install
+
+```sh
+bun add @opencode-ai/client@next
+```
+
+## Create a client
+
+Create a client with the server URL, then call methods grouped by API resource:
+
+```ts
+import { OpenCode } from "@opencode-ai/client"
+
+const client = OpenCode.make({
+  baseUrl: "http://localhost:4096",
+})
+
+const session = await client.session.create({
+  location: { directory: "/workspace" },
+})
+
+await client.session.prompt({
+  sessionID: session.id,
+  text: "Review the current changes",
+})
+```
+
+## Headers and requests
+
+Pass default authentication or application headers to `OpenCode.make` with
+`headers`. You can also supply a custom `fetch` implementation. Each operation
+accepts request options as its final argument for an `AbortSignal` or
+per-request headers.
+
+```ts
+const client = OpenCode.make({
+  baseUrl: "https://opencode.example.com",
+  headers: {
+    authorization: `Bearer ${process.env.OPENCODE_TOKEN}`,
+  },
+})
+
+await client.session.list(undefined, {
+  signal: AbortSignal.timeout(10_000),
+})
+```
+
+## Stream events
+
+Streaming endpoints return async iterables:
+
+```ts
+for await (const event of client.event.subscribe()) {
+  console.log(event.type)
+}
+```
+
+## Effect
+
+OpenCode provides a first-class Effect client through the
+`@opencode-ai/client/effect` entrypoint. It returns typed Effects and Streams
+and decodes responses into OpenCode schema values.
+
+```sh
+bun add @opencode-ai/client@next effect

+Streaming operations, including `client.event.subscribe()` and
+`client.session.log(...)`, return Effect `Stream` values.
+
+### Service
+
+`Service` discovers and manages the local OpenCode background service from a
+Node application:
+
+- `Service.discover()` returns a healthy registered endpoint without starting
+  a process.
+- `Service.start()` reuses a compatible service or starts one when needed.
+- `Service.stop()` stops the registered service.

+
+Plugins extend OpenCode in-process. They can transform agents, models, commands,
+integrations, references, skills, and tools; intercept model requests and tool
+execution; and call a subset of the V2 client.
+
+<Warning>
+  The V2 plugin API is beta. Entrypoints, hooks, draft shapes, and configuration may change before the stable release.
+  Use the `/v2` exports described on this page.
+</Warning>
+
+## Load plugins
+
+Plugins can be loaded from npm packages, explicit local paths, or config
+directories. Each module must have one default export containing a unique
+plugin `id` and a `setup` function.
+
+### Configuration
+
+Add ordered entries to the `plugins` field in `opencode.json(c)`:
+
+```jsonc title="opencode.jsonc"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "plugins": [
+    "opencode-acme-plugin@1.2.0",
+    "@acme/opencode-plugin",
+    "./plugins/local.ts",
+    {
+      "package": "./plugins/reviewer.ts",
+      "options": {
+        "agent": "reviewer",
+        "strict": true,
+      },
+    },
+  ],
+}
+```
+
+A string is either a package specifier or a local path. Local paths must start
+with `./` or `../` and resolve relative to the configuration file containing
+the entry. Absolute paths and `file://` URLs are also supported. Both scoped
+packages and versioned package specifiers are supported.
+
+Use the object form to pass JSON configuration to the plugin. OpenCode passes
+`options` unchanged as `ctx.options`; omitted options become an empty object.
+The plugin owns validation and defaults for its options.
+
+See [Config](/docs/config#locations) for configuration locations and precedence.
+Entries from all applicable files are processed from lowest to highest
+precedence rather than replacing the entire array.
+
+### Local discovery
+
+OpenCode automatically scans this directory in every discovered OpenCode config
+directory:
+
+```text
+.opencode/plugins/
+```
+
+The equivalent global directory is `~/.config/opencode/plugins/`. Direct `.ts`
+and `.js` children are loaded. An immediate child directory is also loaded as a
+package when OpenCode can resolve a string `exports`, `module`, or `main`
+entrypoint, or an `index.ts` or `index.js` file.
+
+A `plugins/` directory beside a project-root `opencode.json` is not discovered
+automatically. Put it under `.opencode/`, or add its file explicitly with a
+relative config entry.
+
+### Enable and disable
+
+A string beginning with `-` disables plugins by their exported `id`. `*`
+matches every ID, and a suffix of `.*` matches an ID prefix. Directives are
+applied in order:
+
+```jsonc title="opencode.jsonc"
+{
+  "plugins": ["./plugins/reviewer.ts", "-acme.reviewer", "-opencode.provider.*", "opencode.provider.openai"],
+}
+```
+
+Package specifiers and local paths locate plugin modules; they are not disable
+selectors. Use the `id` from the plugin's default export to disable it. A later
+ID entry re-enables a loaded or built-in plugin. Explicit config directives run
+after local auto-discovery, so they can disable discovered plugins by ID.
+
+User plugins are activated in configured order between OpenCode's internal
+plugin phases. Hooks run sequentially in registration order, and later hooks
+observe earlier mutations. Do not depend on the internal phase ordering while
+the API is beta.
+
+### Installation and dependencies
+
+OpenCode installs bare package entries and their production dependencies into
+an isolated cache. Package installation does not run lifecycle scripts.
+Published packages should expose their plugin entrypoint and include every
+runtime import in `dependencies`.
+
+Local files and local package directories are imported directly. OpenCode does
+**not** install their dependencies. Install dependencies in a `package.json`
+visible from the plugin file, for example:
+
+```sh
+cd .opencode
+bun add @opencode-ai/plugin@next
+```
+
+Match the plugin package version to the OpenCode release you target.
+
+Configuration and discovered plugin files under watched config directories are
+reloaded when they change. Reloading replaces the active plugin generation and
+releases its scoped registrations. Restart OpenCode after changing an npm
+package version or a local dependency when no watched file changed.
+
+## Create a plugin
+
+Export the result of `Plugin.define` as the module default:
+
+```ts title=".opencode/plugins/reviewer.ts"
+import { Plugin } from "@opencode-ai/plugin/v2"
+
+export default Plugin.define({
+  id: "acme.reviewer",
+  setup: async (ctx) => {
+    const description =
+      typeof ctx.options.description === "string" ? ctx.options.description : "Reviews code for regressions"
+
+    await ctx.agent.transform((agents) => {
+      agents.update("reviewer", (agent) => {
+        agent.description = description
+        agent.mode = "subagent"
+      })
+    })
+  },
+})
+```
+
+`setup` runs each time the plugin is activated. Register long-lived behavior
+during setup; do not wait there on an infinite event stream. It may return a
+synchronous or asynchronous cleanup function. OpenCode awaits that cleanup
+when the plugin is disabled, reloaded, or shut down:
+
+```ts
+setup: async (ctx) => {
+  const controller = new AbortController()
+  const task = synchronize(ctx, controller.signal)
+
+  return async () => {
+    controller.abort()
+    await task
+  }
+}
+```
+
+Hook registrations are released automatically with the same plugin scope. Use
+the returned cleanup for resources the plugin owns, such as timers, watchers,
+connections, and background tasks.
+
+### Context
+
+The plugin context is essentially an [OpenCode server client](/docs/build/client).
+Its read and action methods use the same inputs and responses as the client. It
+adds plugin-only methods for transforms, runtime hooks, reloads, registrations,
+and plugin options.

+### Transform hooks
+
+Transform hooks let a plugin modify how OpenCode is configured. Use them to add
+or remove definitions, override settings, choose defaults, and provide tools or
+other sources.
+
+| Transform               | Draft operations                                                                                        |

+| `agent.transform`       | `list`, `get`, `default`, `update`, `remove`                                                            |
+| `catalog.transform`     | Provider `list`, `get`, `update`, `remove`; model `get`, `update`, `remove`; default model `get`, `set` |
+| `command.transform`     | `list`, `get`, `update`, `remove`                                                                       |
+| `integration.transform` | Integration `list`, `get`, `update`, `remove`; method `list`, `update`, `remove`                        |
+| `reference.transform`   | `add`, `remove`, `list`                                                                                 |
+| `skill.transform`       | `source`, `list`                                                                                        |

+
+Here's an example that keeps models synced from a remote source:
+
+```js title=".opencode/plugins/remote-models.js"
+import { Plugin } from "@opencode-ai/plugin/v2"
+
+export default Plugin.define({
+  id: "acme.remote-models",
+  setup: async (ctx) => {
+    let models = []
+
+    await ctx.catalog.transform((catalog) => {
+      for (const model of models) {
+        catalog.model.update(model.providerID, model.id, (draft) => Object.assign(draft, model))
+      }
+    })
+
+    const refresh = async () => {
+      const response = await fetch("https://example.com/opencode/models.json", {
+        signal: AbortSignal.timeout(10_000),
+      })
+      if (!response.ok) return
+      models = await response.json()
+      await ctx.catalog.reload()
+    }
+
+    await refresh()
+    const timer = setInterval(() => void refresh().catch(console.error), 60_000)
+    return () => clearInterval(timer)
+  },
+})
+```
+
+`ctx.catalog.reload()` replays every catalog transform to derive the new
+catalog. Each plugin's logic remains composed with the others, so a later
+plugin can still modify models added by an earlier one. The catalog updates
+without restarting OpenCode.
+
+### Runtime hooks
+
+Runtime hooks intercept live operations. Their event objects expose specific
+mutable fields:
+
+| Hook                                        | Mutable fields                                                                 |
+| ------------------------------------------- | ------------------------------------------------------------------------------ |
+| `ctx.aisdk.hook("sdk", callback)`           | `sdk`, after inspecting `model`, `package`, and `options`                      |
+| `ctx.aisdk.hook("language", callback)`      | `language`, after inspecting `model`, `sdk`, and `options`                     |
+| `ctx.session.hook("request", callback)`     | `system`, `messages`, and the `tools` record immediately before model dispatch |
+| `ctx.tool.hook("execute.before", callback)` | `input`, before the selected tool executes                                     |
+| `ctx.tool.hook("execute.after", callback)`  | `result`, `output`, and `outputPaths`, after execution settles                 |
+
+For example, remove a tool from selected model requests and normalize another
+tool's input:
+
+```ts title=".opencode/plugins/guards.ts"
+import { Plugin } from "@opencode-ai/plugin/v2"
+
+export default Plugin.define({
+  id: "acme.guards",
+  setup: async (ctx) => {
+    await ctx.session.hook("request", (event) => {
+      delete event.tools.write
+    })
+
+    await ctx.tool.hook("execute.before", (event) => {
+      if (event.tool !== "lookup" || typeof event.input !== "object" || event.input === null) return
+      event.input = { ...event.input, source: "plugin" }
+    })
+  },
+})
+```
+
+A hook failure fails the operation it intercepts. Keep runtime hooks fast and
+handle expected errors inside the callback.
+
+## Examples
+
+### Add a tool
+
+Pass a tool declaration to `tools.add`. Define its input with JSON Schema and
+use an async executor:
+
+```js title=".opencode/plugins/greeting.js"
+import { Plugin } from "@opencode-ai/plugin/v2"
+
+export default Plugin.define({
+  id: "acme.greeting",
+  setup: async (ctx) => {
+    await ctx.tool.transform((tools) => {
+      tools.add({
+        name: "greeting",
+        description: "Create a greeting",
+        jsonSchema: {
+          type: "object",
+          properties: {
+            name: { type: "string" },
+          },
+          required: ["name"],
+          additionalProperties: false,
+        },
+        execute: async ({ name }) => {
+          const text = `Hello, ${name}!`
+          return {
+            structured: { greeting: text },
+            content: [{ type: "text", text }],
+          }
+        },
+      })
+    })
+  },
+})
+```
+
+Unsupported characters in tool and group names are normalized to underscores.
+The resulting exposed key must begin with a letter and contain at most 64
+letters, digits, underscores, or hyphens. Set `options` on the declaration to
+configure registration with `{ group, deferred }`:
+
+- `group` prefixes and groups the exposed tool name.
+- `deferred: true` makes the tool available through the deferred `execute`
+  tool instead of exposing it directly.
+
+The executor receives a second context argument containing `sessionID`,
+`agent`, `assistantMessageID`, and `toolCallID`.
+
+### Add a command
+
+```js title=".opencode/plugins/review-command.js"
+import { Plugin } from "@opencode-ai/plugin/v2"
+
+export default Plugin.define({
+  id: "acme.review-command",
+  setup: async (ctx) => {
+    await ctx.command.transform((commands) => {
+      commands.update("review", (command) => {
+        command.description = "Review the current changes"
+        command.template = "Review the current changes for correctness and missing tests."
+      })
+    })
+  },
+})
+```
+
+### Set the default model
+
+```js title=".opencode/plugins/default-model.js"
+import { Plugin } from "@opencode-ai/plugin/v2"
+
+export default Plugin.define({
+  id: "acme.default-model",
+  setup: async (ctx) => {
+    await ctx.catalog.transform((catalog) => {
+      catalog.model.default.set("anthropic", "claude-sonnet-4-5")
+    })
+  },
+})
+```
+
+## Publish a package
+
+A package plugin uses the same default export as a local plugin. A minimal
+manifest is:
+
+```json title="package.json"
+{
+  "name": "opencode-acme-plugin",
+  "version": "1.0.0",
+  "type": "module",
+  "exports": "./src/index.ts",
+  "dependencies": {
+    "@opencode-ai/plugin": "next"
+  }
+}
+```
+
+Use versions compatible with the OpenCode release you target and test the
+installed package, not only a workspace-linked copy. Because the plugin API is
+beta, publish compatible plugin updates when V2 entrypoints or contracts
+change.
+
+## Verify loading
+
+List active plugin IDs through the V2 API:
+
+```sh
+opencode2 api get /api/plugin
+```
+
+If a plugin is absent, check the server log described in
+[Troubleshooting](/docs/troubleshooting#read-logs). Invalid modules and setup failures are
+logged; one failing package does not prevent unrelated valid packages from
+being resolved.
+
+## Effect
+
+OpenCode provides a first-class Effect API for plugins through the
+`@opencode-ai/plugin/v2/effect` entrypoint. Install `effect` alongside the
+plugin package and export an `effect` function instead of `setup`:
+
+```sh
+bun add @opencode-ai/plugin@next effect
+```
+
+```ts title=".opencode/plugins/reviewer-effect.ts"
+import { Plugin } from "@opencode-ai/plugin/v2/effect"
+import { Effect } from "effect"
+
+export default Plugin.define({
+  id: "acme.reviewer-effect",
+  effect: (ctx) =>
+    Effect.gen(function* () {
+      yield* ctx.agent.transform((agents) => {
+        agents.update("reviewer", (agent) => {
+          agent.description = "Reviews code for regressions"
+          agent.mode = "subagent"
+        })
+      })
+    }),
+})
+```
+
+Context operations return Effects. The plugin effect is scoped, so finalizers,
+fibers, and registrations are released when the plugin reloads or unloads.
+OpenCode does not expose its private Core services to the plugin; use the
+capabilities on `ctx`.
+
+Typed tools can use `Schema` from `effect` and the contracts exported from
+`@opencode-ai/plugin/v2/effect/tool`. Their executors return an Effect and may
+fail with the typed tool failure channel.

+title: "SDK"
+description: "Embed an OpenCode host in an Effect application."
+---
+
+`@opencode-ai/sdk-next` is the Effect-native SDK for applications that need to
+host OpenCode in-process. Unlike the [network client](/docs/build/client), it assembles the
+OpenCode server and routes API calls through its HTTP router in memory. It opens
+no HTTP listener and adds no network hop between the client and server.
+
+<Warning>
+  The V2 SDK is beta and currently private to the OpenCode workspace. It is not
+  published for external installation yet, and its package name and API may
+  change before release.
+</Warning>
+
+## Create a host
+
+`OpenCode.create()` creates a scoped host. Closing its Effect Scope releases
+the router, location services, fibers, and scoped plugin registrations.
+
+```ts
+import {
+  AbsolutePath,
+  Location,
+  OpenCode,
+} from "@opencode-ai/sdk-next"
+import { Effect } from "effect"
+
+const program = Effect.scoped(
+  Effect.gen(function* () {
+    const opencode = yield* OpenCode.create()
+    const session = yield* opencode.sessions.create({
+      location: Location.Ref.make({
+        directory: AbsolutePath.make("/workspace"),
+      }),
+    })
+
+    return yield* opencode.sessions.get({ sessionID: session.id })
+  }),
+)
+
+const session = await Effect.runPromise(program)
+```
+
+The embedded host uses the same routes, middleware, codecs, errors, and schema
+values as `@opencode-ai/client/effect`. It exposes the full generated client and
+adds the convenience aliases `sessions` and `events` for the session and event
+groups.
+
+## Use as a service
+
+Use `OpenCode.layer` when the host should be provided through Effect dependency
+injection:
+
+```ts
+import { OpenCode } from "@opencode-ai/sdk-next"
+import { Effect } from "effect"
+
+const program = Effect.gen(function* () {
+  const opencode = yield* OpenCode.Service
+  return yield* opencode.sessions.active()
+})
+
+const active = await Effect.runPromise(
+  program.pipe(Effect.provide(OpenCode.layer)),
+)
+```
+
+## Register plugins
+
+Call `opencode.plugin(...)` to register an embedded V2 plugin. Embedded plugins
+use the same discovery and location-scoped activation path as configured
+plugins. The SDK also exports `Tool` for plugin-defined tools. See the
+[Plugins guide](/docs/build/plugins) for the plugin shape and available hooks.
