-name: opencode-drive
-description: Use when an agent needs drive OpenCode via a script or interact with an isolated instance
----
-
-# OpenCode Drive
-
-Use `opencode-drive` to launch an isolated OpenCode instance and control it via commands or a script.
-
-There are two modes. Always default to using a script unless specifically directed to be interactive (connect
-to an existing running instance, or start a new one, and make a few changes to the UI and read it, and iterate
-on changes).
-
-Scripts allow you to run a full walkthrough in one run. When the script is done opencode-drive exits,
-stops all processes, and cleans up all artifacts.
-
-# Prepare The Environment
-
-Use `init` when files must be added to the isolated home or project before OpenCode starts. It prints the artifact directory without launching OpenCode. A later `start` with the same name reuses it.
-
-```bash
-artifacts=$(opencode-drive init --name demo)
-cp -R ./fixtures/home/. "$artifacts/"
-cp -R ./fixtures/project/. "$artifacts/files/"
-opencode-drive start --name demo --dev ~/projects/opencode
-```
-
-The simulated project is under `$artifacts/files`. Running `start` without a prior `init` initializes the artifacts automatically.
-
-# Scripted usage
-
-You can write scripts that walk through entire flows, and gives you full access to controlling
-the backend too. See examples of the script API at the bottom of this file.
-
-After creating or editing a script, always typecheck it before running. Never skip this step:
-
-```bash
-opencode-drive check ./reproduce-stale-exploring-empty.ts
-```
-
-Run it by passing `--script` to start:
-
-```bash
-opencode-drive start --name auto-stop-reproduction --script ./reproduce-stale-exploring-empty.ts
-```
-
-It will output information about the run, including paths to log files which you can read
-to inspect what happened. If you need to dig into failures that aren't clear, read those log
-files. If the script is unsuccessful, automatically fix the script and run it again.
-
-Scripts use one typed definition object. `setup` runs before OpenCode starts,
-and `fs.writeFile` always writes inside the simulated project.
-
-You can read the full typed API here: https://raw.githubusercontent.com/jlongster/opencode-drive/refs/heads/main/src/script/types.ts
-
-```ts
-import { defineScript } from "opencode-drive"
-
-export default defineScript({
-  async setup({ fs, config }) {
-    config.autoupdate = false
-    await fs.writeFile("src/example.ts", "export const value = 1\n")
-  },
-
-  async run({ ui, llm }) {
-    await ui.submit("Open src/example.ts")
-    await llm.send(llm.text("The file exports `value`."))
-    await ui.waitFor("The file exports `value`.")
-  },
-})
-```
-
-`setup` receives the current OpenCode config object, which starts from the
-default drive config unless the prepared instance already has one. When a script
-needs custom config, mutate this `config` parameter instead of generating and
-writing a new config object from scratch, so the script keeps the default
-provider/model settings unless it intentionally changes them.
-
-Note that the simulated model is a GPT model type, and opencode uses the `patch` tool for working with files Do not use a `edit` or `write` tool to edit files.
-
-Use `launch: "manual"` when the script needs to launch the server and every TUI
-itself (this is extremely rare, do not use this unless explicitly asked). In this
-mode `ui` is typed as `null`; call `server.launch()` exactly
-once before launching clients. Each `clients.launch(name)` result provides the
-same UI methods as the automatic client. You can see an example of this API
-here: https://raw.githubusercontent.com/jlongster/opencode-drive/refs/heads/main/examples/multiple-clients.ts
-
-Use the exported `wait(milliseconds)` utility for an unconditional delay.
-
-`await llm.send(...)` waits for the next request and resolves after OpenCode
-acknowledges its complete response. `llm.queue(...)` declares responses in
-advance. Chunks may be built with `text`, `reasoning`, `toolCall`, `raw`,
-`finish`, and `disconnect`. A normal response receives `finish("stop")`
-automatically unless it yields or queues an explicit terminal event.
-
-`llm.text(text, { delay, chunkSize })` defaults to a 2 ms delay and a
-15-character target varied by plus or minus 5 per chunk.
-
-`llm.reasoning` accepts the same options, and `llm.pause(milliseconds)` adds a
-delay between any two outputs.
-
-Use `llm.serve` for an ongoing typed response generator:
-
-```ts
-llm.serve(async function* (request, index) {
-  yield llm.reasoning(`Handling request ${index + 1}`)
-  yield llm.text(`Received ${request.id}`)
-  yield llm.finish("stop")
-})
-```
-
-The backend connection, response cleanup, cancellation, and recording
-completion are automatic.
-
-You can see some example scripts here:
-
-- https://raw.githubusercontent.com/jlongster/opencode-drive/refs/heads/main/examples/simple.ts
-- https://raw.githubusercontent.com/jlongster/opencode-drive/refs/heads/main/examples/serve.ts
-
-## Prune
-
-- `prune` removes artifact directories. These are always cleaned up after running a script
-  successfully, but leftover on failed runs. Always call this if a script fails.
-
-```bash
-opencode-drive prune --name demo
-
-// --force cleans up all artifcat directories
-opencode-dirve prune --force
-```
-
-# Live interaction usage
-
-- Always give headless instances a unique `--name`. Visible instances may omit it.
-- A normal headless `start` detaches automatically and returns after the instance is ready.
-- Do not add `&`; the long-running owner already runs in the background.
-- Configure simulated model responses after startup when needed.
-- Send ordered UI commands with `send`.
-- Always stop the instance when finished.
-
-```bash
-opencode-drive start --name demo
-
-opencode-drive send --name demo \
-  --command.ui.type '{"text":"Explain this project"}' \
-  --command.ui.enter
-
-opencode-drive stop --name demo
-```
-
-## Send UI Commands
-
-- Every `send` opens a connection to the named instance, runs its commands in order, and exits.
-- Combine typing and Enter in one command when submitting a prompt.
-- JSON-valued commands require one JSON argument.
-- Multiple command flags execute from left to right.
-
-Commands:
-
-- `--command.ui.type <json>` types into the focused editor. Arguments: `text` string.
-- `--command.ui.press <json>` presses a key. Arguments: `key` string; optional `modifiers` object with boolean `ctrl`, `shift`, `meta`, `super`, or `hyper`.
-- `--command.ui.enter` presses Enter. Arguments: none.
-- `--command.ui.arrow <json>` presses an arrow key. Arguments: `direction` is `up`, `down`, `left`, or `right`.
-- `--command.ui.focus <json>` focuses an element. Arguments: `target` is the numeric element `num` returned by `ui.state`.
-- `--command.ui.click <json>` clicks an element. Arguments: numeric `target`, `x`, and `y`; use the element `num` returned by `ui.state` as `target`.
-- `--command.ui.state` prints focus and interactive element metadata as JSON. Arguments: none.
-- `--command.ui.matches <json>` prints whether literal, case-sensitive text appears on screen. Arguments: `text` string.
-
-```bash
-opencode-drive send --name demo \
-  --command.ui.type '{"text":"Find the relevant code and explain it"}' \
-  --command.ui.enter
-
-opencode-drive send --name demo \
-  --command.ui.press '{"key":"p","modifiers":{"ctrl":true}}'
-
-opencode-drive send --name demo \
-  --command.ui.arrow '{"direction":"down"}'
-
-opencode-drive send --name demo \
-  --command.ui.focus '{"target":12}'
-
-opencode-drive send --name demo \
-  --command.ui.click '{"target":12,"x":4,"y":1}'
-
-opencode-drive send --name demo \
-  --command.ui.matches '{"text":"OpenCode"}'
-```
-
-To read the UI state and see information about interactable elements, use the `ui.state` command:
-
-```bash
-opencode-drive send --name demo --command.ui.state
-```
-
-## Configure LLM Responses
-
-- `responses` controls what the LLM responds with
-- Only use this if you are wanting to reproduce an exact type of response
-- Defaults are `text,reasoning,diff,tool` with `write,apply_patch`.
-- Supported types are `text`, `reasoning`, `diff`, and `tool`.
-- `--tools` limits generated tool calls to names offered by OpenCode.
-
-```bash
-opencode-drive responses --name demo \
-  --types text,reasoning,diff,tool \
-  --tools write,apply_patch
-
-opencode-drive responses --name demo \
-  --types tool \
-  --tools read,glob,grep
-```
-
-## Inspect The UI
-
-- `ui.state` prints focus and interactive element metadata as JSON.
-- `ui.matches` checks for literal, case-sensitive screen text.
-- `screenshot` prints the generated image path.
-
-```bash
-opencode-drive screenshot --name demo
-```
-
-## Lifecycle
-
-- `stop` waits for recording export and owner cleanup before returning.
-
-```bash
-opencode-drive stop --name demo
-```
-
-# Record The UI
-
-- Start with `--record` to capture a headless instance from its first rendered frame.
-- `stop` finishes the recording, exports an MP4, and prints its path.
-
-```bash
-opencode-drive start --name demo --record
-
-opencode-drive send --name demo \
-  --command.ui.type '{"text":"Show me the current architecture"}' \
-  --command.ui.enter
-
-opencode-drive stop --name demo
-```
-
-# Artifacts dir
-
-- `dir` prints the artifact directory for the instance.
-
-```bash
-opencode-drive dir --name demo
-```

-## When To Use
-
-- Use when the user asks for a sample skill or skill template.
-- Use when demonstrating the required `SKILL.md` frontmatter and body format.
-- Do not use for unrelated coding tasks just because a skill exists.
-
-## Workflow
-
-- Confirm the specific outcome the user wants if the request is ambiguous.
-- Inspect the relevant files before changing anything.
-- Make the smallest correct change.
-- Verify the result with a focused read, typecheck, test, or other lightweight check when available.
-- Summarize the changed files and any required restart or reload step.

 - Keep things in one function unless composable or reusable
 - Do not extract single-use helpers preemptively. Inline the logic at the call site unless the helper is reused, hides a genuinely complex boundary, or has a clear independent name that improves the caller.
-- Before adding complexity for a speculative or vanishingly unlikely race or security edge case, explain the concrete failure mode, likelihood, and complexity cost to the user and get their buy-in. Do not silently expand scope for theoretical robustness.

 - Avoid using the `any` type

 ## V2 Session Core
 
-- Keep durable events minimal: record irreducible new facts and do not repeat state derivable by folding the ordered aggregate history. Enrich projections and read models with previous or derived state when consumers need self-contained views.
-- Keep durable prompt admission separate from model execution. `SessionV2.prompt(...)` admits one durable `session_pending` row before scheduling advisory `SessionExecution.wake(sessionID)` unless `resume: false` requests admit-only behavior. The serialized runner promotes admitted inputs into visible user messages at safe boundaries, consuming the pending row in the same event transaction; `session_pending` stores only unconsumed work.
-- Reusing a Session ID adopts the existing Session. Reusing a prompt message ID reconciles an exact retry only when Session, prompt, and delivery mode match; conflicting reuse fails. Retry of an already-promoted input reconciles against the projected message and the durable admitted event rather than a retained row.
-- Keep `SessionExecution` process-global and Session-ID based. Its local implementation owns the process-local Session coordinator and discovers placement through `SessionStore` plus `LocationServiceMap.get(session.location)` only when a drain starts; no layer should take a Session ID. V2 interruption targets the active process-local ownership chain for that Session; interruption of a known but idle or locally unowned Session is a no-op, while the public API rejects an unknown Session.

 - Keep `SessionRunner`, model resolution, tool registry, permissions, and filesystem Location-scoped. Omitted `Location.workspaceID` means implicit-local placement; explicit workspace identity remains reserved for future placement semantics.
-- Preserve one explicit `llm.stream(request)` call per Physical Attempt and reload projected history before durable continuation. Most Steps have one Physical Attempt; overflow-triggered compaction recovery may rebuild one Step for a second attempt. Do not bridge through legacy `SessionPrompt.loop(...)` or delegate orchestration to an in-memory tool loop.

Advisory wakes drain eligible durable inbox rows only; post-crash continuation recovery requires a separate explicit design before it may retry provider work. A drain has no durable identity or transcript boundary.
-- Keep delivery vocabulary explicit. Prompts steer by default and promote at the next safe step boundary while the current drain requires continuation. An explicit `queue` input remains pending until the Session would otherwise become idle; promote one queued input at that boundary, then reevaluate continuation before promoting another. Promoting any new user input resets the selected agent's step allowance; a batch of steers resets it once.

Unavailable sources retain the last value and block only the initial complete delta.

 ## Relationships
 
-- **Instructions** is an opaque carrier composed from zero or more **Instruction Sources**.
-- **Model Context** is broader than **Instructions**. For each **Step**, the runner assembles the selected agent or provider system text, **Initial Instructions**, **Session History**, available tools, and step-local additions into one model request.
-- **Session History** persists conversational messages. The runner derives model-facing **Instruction Update** messages from value deltas and interleaves them by durable sequence; **Initial Instructions** remain separate provider-request state.
-- The runner explicitly loads and combines instruction built-ins, **InstructionDiscovery**, selected-agent skill guidance, reference guidance, MCP guidance, and **InstructionEntry** values. There is no instruction registry.
-- `Instructions.combine(...)` preserves caller order and rejects duplicate stable namespaced source keys. The runner loads its producers concurrently, then combines them in its fixed declared order.
-- Each **Instruction Source** read returns one coherent typed value, explicit removal, or temporary unavailability. `Instructions.make(...)` hides the value type so differently typed sources compose uniformly; its canonical codec defines storage and hash equivalence, while pure renderers produce first, changed, and optional removal text.
-- `Instructions.read(...)` reads every composed source concurrently and exactly once at the boundary. `Instructions.diff(...)` compares encoded-value hashes with current **Instruction Values** and returns one delta plus new blob bodies.
-- `Instructions.renderInitial(...)` renders values at the **Instruction Epoch** start. `Instructions.renderUpdate(...)` renders one hydrated delta against the values immediately before it.
-- A changed **Instruction Source** contributes its hash to one **Instruction Update**; explicit removal contributes the `"removed"` sentinel.
-- An **Instruction Update** persists only its value delta. Rendered text is derived during request assembly and excluded from compaction summaries.
-- The instruction blob insert, durable delta, and **Instruction State** advance commit atomically.
-- Changes from multiple **Instruction Sources** admitted at one safe boundary combine into one **Instruction Update**.
-- Instruction changes are sampled and admitted lazily at a **Safe Step Boundary**, never pushed asynchronously when their source changes.
-- At a **Safe Step Boundary**, prior tool results are already settled; instruction preparation completes before newly admitted user input promotes.
+- A **System Context** is an opaque carrier composed from zero or more **Context Sources**.
+- **Session History** contains projected conversational messages and admitted **Mid-Conversation System Messages**; the active **Baseline System Context** remains separate provider-request state.
+- The **System Context Registry** uses stable-keyed scoped contributions to assemble the current **System Context**; contributor removal naturally removes its sources at the next **Safe Provider-Turn Boundary**.
+- A changed **Context Source** may produce one **Mid-Conversation System Message** containing its newly effective state.
+- A **Mid-Conversation System Message** persists the exact combined rendered text sent to the model.
+- The current **Context Snapshot** advances atomically with the corresponding durable **Mid-Conversation System Message**.
+- A **Context Snapshot** stores one codec-encoded JSON value and, for removable dynamic sources, a pre-rendered removal message per stable **Context Source** key.
+- Changes from multiple **Context Sources** admitted at one safe boundary combine into one **Mid-Conversation System Message**.
+- Context changes are sampled and admitted lazily at a **Safe Provider-Turn Boundary**, never pushed asynchronously when their source changes.
+- At a **Safe Provider-Turn Boundary**, newly promoted user input or settled tool results precede any combined **Mid-Conversation System Message**.
 - An **Admitted Prompt** is replayable pending input, not yet model-visible **Session History**.
 - **Prompt Promotion** atomically consumes the pending inbox entry and appends its model-visible user message.
-- Steering prompts promote at the next **Safe Step Boundary** while the current **Session Drain** still requires continuation. Promoting any newly admitted user input resets the selected agent's step allowance; multiple prompts promoted at one boundary reset it once.
+- Steering prompts promote at the next **Safe Provider-Turn Boundary** while the current **Session Drain** still requires continuation. Promoting any newly admitted user input resets the selected agent's provider-turn allowance; multiple prompts promoted at one boundary reset it once.
 - A queued prompt does not promote while the current **Session Drain** requires continuation. The runner promotes one queued prompt when the Session would otherwise become idle, then reevaluates continuation before promoting another.
-- A **Session Drain** is process-local coordination rather than a durable domain entity. Durable recovery must reason from prompts, projected history, physical attempts, and tool state rather than inventing an enclosing execution identity.
-- An **Execution** contains one or more **Session Drains**; a **Session Drain** contains one reserved assistant-turn span at a time; that span contains **Steps**; and each **Step** contains one or more **Physical Attempts** plus any tool calls it requires.
-- A **Step** record covers only the model-visible span from first assistant output through tool settlement; pre-flight leaves no record, and one Step settles at most one record.
-- The first **Step** admits one complete delta and renders **Initial Instructions** without narrating that delta in history; an unavailable initial source blocks the Step instead of persisting incomplete values.
-- Instruction preparation precedes durable input promotion on every Step so an unavailable first baseline leaves pending input untouched and later updates enter history before newly promoted input.
-- Completed compaction moves the **Instruction Epoch** to the exact `session.compaction.ended` sequence and copies current hashes to the epoch's initial values. Earlier updates leave active model history while durable deltas remain.
-- A newly composed **Instruction Source** absent from current **Instruction Values** emits its first rendering once at the next **Safe Step Boundary**.
-- **Unavailable Instruction Source** uses stale-while-revalidate semantics and is distinct from a successfully loaded absence, which may emit removal text.
-- **InstructionDiscovery** observes ambient instructions as one ordered aggregate **Instruction Source**.
-- Ambient discovery reads global and upward-project `AGENTS.md` files and honors `OPENCODE_DISABLE_PROJECT_CONFIG` for project files.
-- After a successful internal file or directory read, nearby `AGENTS.md` files toward the Location root are injected once per Session as durable synthetic instruction messages.
-- **InstructionEntry** stores API-managed per-Session JSON values. Each entry contributes one `api/<key>` **Instruction Source**, so adding, replacing, or removing an entry is reconciled at the next **Safe Step Boundary**.
-- Location-scoped instruction producers naturally re-resolve when a moved Session next runs in its destination Location.
-- Moving a Session clears its **Instruction State**, so the destination must admit a complete delta before another prompt can promote. Committed revert does the same; replay derives both resets from their durable events.
-- Selected-agent available-skill guidance is an **Instruction Source** composed explicitly by the runner. It lists only names and descriptions permitted for that agent; skill bodies and locations are exposed only through the permission-checked `skill` tool.
-- The selected agent and model are sampled when a **Step** starts. Changes admitted after that boundary apply to the next Step and do not restart the current Step.
-- An agent switch that changes selected-agent guidance produces an **Instruction Update** while preserving the current baseline.
-- Local tool authorization and pending permission requests retain the effective agent of the **Step** that issued the call; a later agent switch cannot change that call's policy.
-- Instruction source changes never wake idle Sessions; the next naturally scheduled **Safe Step Boundary** loads and compares current values lazily.
-- Once admitted, an **Instruction Update** remains durable even if the following **Physical Attempt** fails and is replayed unchanged on retry.
-- **Instruction Updates** remain durable value history but are not `session_message` rows. Clients display changed keys rather than model-facing prose.
-- The date **Instruction Source** initially preserves host-local calendar-date behavior; a configured user timezone may replace that default later.
-- **Initial Instructions** are recomputed deterministically from durable values for every request; rendered bytes are not stored.
-- A model/provider switch preserves current **Instruction Values**, the **Instruction Epoch**, and chronological conversation history; the new selection applies to the next **Step**.
-- **Native Continuation Metadata** remains in durable history. Step projection includes it only for a successful exact originating provider/model match; failed Steps and incompatible models omit opaque metadata, while non-empty visible reasoning lowers to ordinary assistant text after a model switch.

+- `SystemContext.initialize(...)` observes a composed **System Context** once and produces a fresh **Baseline System Context** with its **Context Snapshot**.
+- `SystemContext.reconcile(...)` observes a composed **System Context** once and returns exactly one next action: unchanged, updated, replacement ready, or replacement blocked.
+- `SystemContext.replace(...)` renders a fresh generation after completed compaction or another baseline-replacing transition; it reports replacement blocked while previously admitted context is unavailable.
+- **Unavailable Context** uses stale-while-revalidate semantics and is distinct from a successfully loaded absence, which may emit removal text.
+- Ordinary **Context Source** loaders return values directly; loaders that intentionally use stale-while-revalidate may explicitly return **Unavailable Context**.
+- Nested project instruction discovery after successful reads remains a follow-up; when implemented, discovered instructions must be admitted durably at the next **Safe Provider-Turn Boundary**.
+- Location-scoped services naturally re-resolve effective context when a moved session next runs in its destination location.
+- Moving a Session clears its active **Context Epoch**, so the destination must initialize a complete baseline before another prompt can promote.
+- Instruction discovery, source identity, persistence, and file loading belong to the instruction service; the **System Context** abstraction only composes effectful producers and renders loaded values.
+- The first instruction-service slice observes global and upward project `AGENTS.md` files as one ordered aggregate **Context Source** at each **Safe Provider-Turn Boundary**.

+- A **Baseline System Context** is stored durably and reused verbatim across process restarts within its **Context Epoch**.
+- A **Baseline System Context** durably preserves the exact joined text used for the active provider-cache prefix.
+- Completed compaction starts a new **Context Epoch** on the next provider attempt, folding the current complete **System Context** into a fresh baseline and removing earlier **Mid-Conversation System Messages** from active model history.
+- A model/provider switch preserves the current **Context Epoch** and chronological conversation history; the new selection applies to the next provider turn.
+- **Native Continuation Metadata** remains in durable history.
