Vasanthdev2004 330b10fe8e docs(readme): clarify /loop runs a prompt or custom command, not built-ins 2026-07-06 08:59:06 +05:30
Vasanthdev2004 ac25352e12 fix(tui): address /loop review round 2 — ticker re-arm, self-paced command, resume guard
- stopLoop re-arms the poll ticker after removing one loop, so stopping one of
  several no longer strands the rest with no tick scheduled (jatmn).
- a bare self-paced /command is rejected with a pointer to the interval form:
  self-paced drives a free-form goal via the playbook + LOOP: control line, which
  a custom command's expanded template never carries, so it would silently
  degrade to adaptive polling (jatmn).
- /resume only tears loops down on an actual session-id change; /resume latest or
  /resume <currentID> can resolve to the already-active session, whose loops are
  its own, not a "previous" session's (CodeRabbit).
- tests: skipped-behind-modal loop stays scheduled, footer carries the next-wake
  time, the confirmed /clear actually wipes the transcript, plus multi-loop stop
  keeping the ticker alive and self-paced-/command rejection.

Vasanthdev2004 de7f0b6a5b fix(tui): finish /loop v1 — real self-paced completion, session scope, leave gate
Response to the review. The self-paced path was the real gap: it advertised
model-chosen completion but nothing ever wrote the done/next-wake fields, so it
was just adaptive polling dressed up. Replaced that with an actual control
channel — each self-paced iteration runs a short maintenance playbook and ends
its reply with a control line (LOOP: DONE / LOOP: CONTINUE [interval]) that
advanceLoop parses to stop the loop or pick the next wake. The two dead model
fields are gone; done and next-wake now come from the model's output.

Rest of the review:
- loops stop on a session switch (/new, /resume) instead of firing the previous
  conversation's prompt into the new one
- validateLoopTarget resolves custom /commands up front and rejects unknowns, so
  a mistyped `/loop 5m /nope` isn't scheduled and then re-sent as literal text
- a one-shot confirm gates /clear and /quit while loops are active
- age-based auto-expire (24h) next to the iteration cap
- the two CodeRabbit test nits (HasPrefix footer check, bare `/loop stop` on a
  single loop)

Hardening from a self-review pass over the above:
- normalize CRLF and allow a trailing note on the control line, so
  `LOOP: DONE — all clean` and \r\n replies still stop the loop
- disarm the leave-confirm before the queue/exit early returns, so an interposed
  prompt can't leave it falsely armed
- a loop no longer fires behind an open picker/modal; a run launched behind the
  /resume picker would otherwise complete into whatever session you switch to
2026-07-06 08:53:04 +05:30
Vasanthdev2004 3eafaf584d fix(tui): stop looping on repeated failure + clear loop tag on cancel
Addresses CodeRabbit review on #502:
- advanceLoop now counts consecutive failed iterations (loopMaxFailures=3) and
  stops the loop, so a loop whose turns keep erroring no longer churns to the
  iteration cap (the doom guard only sees identical non-empty answers).
- cancelRun clears activeLoopID and re-arms the interrupted loop for its next
  cadence, so a cancelled iteration is not left running forever and the next
  unrelated turn is not misattributed as that loop's completion.

Vasanthdev2004 9cfdb2fecf docs(readme): add /loop to the slash-command table 2026-07-06 08:53:04 +05:30
Vasanthdev2004 4ffbf4e0fe test(tui): drive /loop end-to-end through Update (submit + stale tick) 2026-07-06 08:53:04 +05:30
Vasanthdev2004 440d4df367 feat(tui): /loop self-paced adaptive cadence + footer summary + /clear note
Third slice of #501.

- Self-paced loops now use an adaptive cadence (2m early -> 30m heartbeat as
  iterations accrue), with the loopNextWake channel kept as an override for a
  future explicit model signal.
- Persistent footer segment "↻ N loops · next 3:05pm" while loops are active.
- /clear notes that loops keep running (it wipes the transcript, not the session)
  so a loop never silently fires into a cleared screen.
- Tests for adaptive cadence + footer summary.
2026-07-06 08:53:04 +05:30
Vasanthdev2004 4bc9a97176 feat(tui): wire /loop into the turn lifecycle — dispatch, idle tick, continuation
Second slice of #501. Adds the controller and wires it in:

- /loop command registered (commands.go) and dispatched to handleLoopCommand.
- Loop state on the model (loops, activeLoopID, loopSeq/loopTicking poll guards,
  loopNextWake/loopDone self-pace channel).
- An idle poll tick (loopTickMsg, ~1s) fires the earliest due loop only when the
  session is idle — mirrors the launchQueuedMessageIfReady guard so loops and a
  user's queued prompt never collide; a self-perpetuating tea.Tick that stops when
  no loops remain.
- The agentResponseMsg completion seam advances a loop iteration (schedule next
  wake for fixed, model delay for self-paced) with doom-loop, iteration-cap, and
  done stop conditions, restarting the ticker if other loops remain.
- /loop list|stop|stop all, footer summary + list rendering, and a guard that only
  a prompt or custom /command may loop (not a built-in).

Controller tests cover start/advance/self-paced-delay/done/doom/cap/stop/busy.

Vasanthdev2004 6d7d3946c8 feat(tui): /loop foundation — command parsing, loop state, safety bounds
First slice of the /loop feature (#501): the self-contained core with no TUI
wiring yet. parseLoopCommand handles the leading-interval, trailing-"every",
bare-self-paced, and list/stop forms; loopState models one session-scoped loop
with doom-loop + iteration-cap fields; interval/self-pace clamps and duration
formatting round it out, with unit tests. Because Zero drives loops off a Go
timer rather than a cron backend, arbitrary intervals (90s, 7m) are supported
with no whitelist limitation.

description: Extending Zero — how to write AGENTS.md files, custom specialists, skills, hooks, MCP servers, and plugins for the open-source CLI coding agent.
globs: "*.go, *.js, *.md, *.json, *.toml, *.yaml, *.yml"
alwaysApply: false
---
These instructions apply to all work in this repository. For the user-facing
guide to extending Zero with specialists, hooks, plugins, MCP, and skills, see
[docs/EXTENDING.md](docs/EXTENDING.md).
# Extending Zero
## 1. Contribution and Pull Request Rules
Zero is an open-source terminal coding agent. Out of the box it does the obvious things — read, edit, run, search — but the design point of the project is that **every surface is configurable**. This document is the user-facing guide for that configuration.
- Before opening any pull request, **all contributors**—including maintainers,
community contributors, and coding agents—must read and follow
[CONTRIBUTING.md](CONTRIBUTING.md).
- Community pull requests require an existing parent issue with the
`issue-approved` label. Team members may open pull requests through the
internal development process described in `CONTRIBUTING.md`.
- Keep each change focused on the approved or assigned scope. Do not include
unrelated fixes, refactors, formatting churn, generated output, or existing
local changes in the same commit or pull request.
- Discuss new implementation languages, runtimes, major dependency changes,
and broad architectural rewrites with maintainers before implementation.
- Pull request descriptions must explain what changed and why, link the parent
issue when required, and list the tests or verification performed. Include
screenshots or a short recording for user-visible UI changes when practical.
If you only want to *use* Zero, the [README](README.md) is enough. This page is for the other three jobs:
## 2. Repository and Implementation Conventions
1. Tell the agent about *your* project (drop an `AGENTS.md` in your repo).
2. Add new specialist sub-agents.
3. Wire Zero into the rest of your toolchain (MCP, skills, hooks, plugins).
- Use the Go version declared in `go.mod`. Do not hardcode a different local
toolchain version in scripts or documentation.
- Use the repository build and release commands (`make` and
`go run ./cmd/zero-release ...`) instead of inventing parallel build flows.
- Keep tests beside their source files (`foo_test.go` next to `foo.go`). Add a
regression test for behavior changes and run affected concurrent code under
the race detector.
- Never edit files under `third_party/`; they are vendored.
- Prefer one cross-platform function with small conditional checks over
duplicated platform-specific helpers when the behavior can remain unified.
- Do not commit generated benchmark reports from
`internal/perfbench/reports/*.json`; reports are configuration-specific
evidence, not repository state.
- Preserve the user's working tree. Do not overwrite, delete, stage, or commit
unrelated tracked or untracked files.
## 1. Drop a project `AGENTS.md`
## 3. Required Validation
When Zero starts in a directory, it looks for project-level instructions and injects them into the system prompt. The lookup walks from your current working directory **up to the nearest git root** and reads the first matching file at each level — general rules at the repo root, more specific rules in sub-trees. Files are labeled with their directory in the prompt (e.g. `## Project guidelines (services/api/AGENTS.md)`).
Run validation from the repository root before committing, opening a pull
request, or completing an implementation task:
Accepted file names, in priority order at each level:
1. **Formatting check**: `make fmt-check`. If it fails, format with
`go fmt ./...` (or `make fmt`) and run the check again.
2. **Vet**: `go vet ./...` (or `make vet`).
3. **Tests**: `go test ./...`. Use `make test` for the full race-enabled suite,
or run focused tests with `-race`, when concurrency is affected.
4. **Build**: `go run ./cmd/zero-release build`.
5. **Smoke test**: `go run ./cmd/zero-release smoke`.
6. **Advisory lint**: `make lint-static`.
7. **Security**: `make vulncheck`.
8. **Diff hygiene**: `git diff HEAD --check` (covers staged and unstaged
tracked changes).
| Path | Notes |
| --- | --- |
| `./AGENTS.md` | The classic spot — committed to your repo, shared with the team. |
| `./ZERO.md` | Brand-specific alias. Same format, lower priority. |
| `./.zero/AGENTS.md` | Project-local, hidden, gitignored. Personal notes that stay out of git. |
`make lint` currently runs the formatting check and `go vet`; it does **not**
run golangci-lint. The pinned golangci-lint job is advisory in CI while the
existing repository-wide backlog is cleaned up. Fix findings introduced by or
related to the current change. Unrelated pre-existing advisory findings do not
justify expanding a focused pull request; report them separately.
Matching is **case-insensitive** on the basename, so `AGENTS.md`, `Agents.md`, and `agents.md` resolve to the same file on Windows and macOS. The git-tracked filename in this repo is `AGENTS.md` — keep that on case-sensitive filesystems (Linux, the WSL filesystem, or a CI runner) to match what the loader looks for.
Formatting, vet, tests, build, smoke, diff hygiene, and govulncheck are hard
requirements. If a related check fails, fix it. If a required check cannot run
because of the environment or fails for an unrelated external reason, report
the exact failure and obtain maintainer direction rather than silently ignoring
it.
Both files use the same format. YAML frontmatter is optional; the markdown body is loaded as instructions for the agent. Zero reads the file once at session start, so changes take effect on the next `zero` launch — not mid-session.
```markdown
# Project conventions for <your project>
- Build with `make`, not `go build` directly.
- Tests live next to the source file (`foo_test.go` next to `foo.go`).
- Run `make lint` before opening a PR.
- Never edit files under `third_party/` — those are vendored.
```
Tips:
- Keep each file under ~8 KiB. Zero caps the **total** across all matched files at 32 KiB; everything past the cap is dropped.
- Re-state rules in the imperative voice: "Run `make lint`", not "you should consider running the linter".
- Don't put secrets, model IDs, or environment-specific paths in `AGENTS.md`. Use `config.json` for those.
- In a monorepo, drop a narrower `AGENTS.md` in each sub-tree (e.g. `services/api/AGENTS.md`). Zero picks those up automatically when you launch from inside the sub-tree.
- A YAML frontmatter block (`---\n...\n---`) at the top is preserved verbatim in the injected prompt but is not parsed for `globs:` or `alwaysApply:` scoping today — keep the body self-contained.
### Personal guidelines, across every project
For preferences that follow *you*, not a specific repo (tone, tooling habits, workflow), drop a `ZERO.md` in your user config directory: `~/.config/zero/ZERO.md` on Linux/macOS, `%AppData%\Roaming\zero\ZERO.md` on Windows — the same directory as `config.json` and your personal specialists. Same format and 8 KiB cap as the project files above, and the same case-insensitive basename match.
This file is injected as its own `## User guidelines` section, before the project's `AGENTS.md`/`ZERO.md`, and is labeled as personal preference in the prompt: project guidelines are the later, more specific instruction and take precedence over it when the two conflict.
## 2. Custom specialists
Specialists are Zero's sub-agents. Three scopes, in priority order:
| Scope | Path | Shared? |
| --- | --- | --- |
| Built-in | compiled into Zero | yes — `worker`, `explorer`, `code-review` |
| User | `~/.config/zero/specialists/*.md` | no — your machine only |
| Project | `./.zero/specialists/*.md` | yes — the repo team |
Project overrides user overrides built-in when names collide.
A specialist is a markdown manifest with frontmatter and a system prompt:
```markdown
---
description: Reviews API changes for breaking-change risk and missing tests.
tools: read-only,plan
---
You review API changes. For every changed hunk in `internal/api/` or any file
that ends in `_api.go`:
1. Confirm the public signature is backward-compatible, or note the breaking
change explicitly with the migration path.
2. Confirm a corresponding test exists in `internal/api/*_test.go` and that
the new behaviour is exercised.
3. Flag any new exported symbol without a doc comment.
Reply with one JSON object per finding: `{"file", "line", "severity", "message", "fix"}`.
```
CLI management (the prompt is passed inline via `--prompt`):
```bash
zero specialist list
zero specialist show api-reviewer
zero specialist create api-reviewer \
--project \
--description "Reviews API changes" \
--tools read-only,plan \
--prompt "$(cat api-reviewer.md)"
zero specialist edit api-reviewer --project
zero specialist delete api-reviewer --project
zero specialist path # prints the resolved specialists directory
```
The full format spec (frontmatter fields, tool scopes, prompt conventions) is in [`docs/SPECIALISTS.md`](docs/SPECIALISTS.md).
> **Roadmap.** An in-UI specialist manager (create / edit / delete / preview) is on the backlog. Today you use the `zero specialist` CLI subcommands above.
## 3. Skills
Skills are markdown instruction packs the agent can pull in on demand. Each skill is a directory containing a `SKILL.md`. Skills are **user-level only** in this version — there's no project-scoped skill directory yet, so anything you want shared with the team goes in `AGENTS.md` (section 1) or as a hook (section 4).
Discovery root: `$ZERO_SKILLS_DIR` → `$XDG_DATA_HOME/zero/skills` → `~/.local/share/zero/skills/`. A missing directory is fine — Zero just reports "no skills".
```
~/.local/share/zero/skills/
run-benchmarks/
SKILL.md
write-changelog/
SKILL.md
```
`SKILL.md` format:
```markdown
---
description: Run the project's benchmark suite and summarize the deltas.
---
# Run benchmarks
1. `make bench` — captures the wall-clock and RSS before and after.
2. `benchstat before.txt after.txt` — diffs the two.
3. Report any regression > 5% with the function name and the previous value.
```
Only `name` and `description` are recognized in the frontmatter today. The `name` defaults to the directory name. If two skills declare the same name, the one in the lexicographically-first directory wins — duplicates are dropped silently. Plugin-declared skills (section 6) are not yet merged into the loader, so a `skills:` entry inside a plugin's `plugin.json` is not visible to the `skill` tool today.
The `skill` core tool lets the agent load any discovered skill by name.
## 4. Hooks
Hooks fire shell commands on lifecycle events. Configure them in JSON:
- User: `~/.config/zero/hooks.json`
- Project: `./.zero/hooks.json`
```json
{
"enabled": true,
"hooks": [
{
"id": "block-rm-rf",
"event": "beforeTool",
"matcher": "bash",
"command": "/usr/local/bin/zero-hook-block-rmrf.sh",
"enabled": true
},
{
"id": "log-session",
"event": "sessionStart",
"command": "/usr/local/bin/zero-hook-log.sh",
"enabled": true
}
]
}
```
The `args` array (when present) is passed verbatim to `exec.CommandContext`. The actual hook payload — event name, matcher, tool call id, tool name, tool input, tool output, status — is delivered to the command as **JSON on stdin**, not via `${...}` substitution. A typical handler reads stdin and decides what to do:
```bash
#!/usr/bin/env bash
# /usr/local/bin/zero-hook-block-rmrf.sh
set -euo pipefail
payload="$(cat)"
if printf '%s' "$payload" | grep -q '"input":"[^"]*rm[[:space:]]+-rf'; then
echo "refusing rm -rf" >&2
exit 1
fi
```
Events the agent emits (in dispatch order):
| Event | Fires when | Matcher allowed? |
| --- | --- | --- |
| `beforeTool` | A tool is about to run | yes (tool name) |
| `afterTool` | A tool just returned | yes (tool name) |
| `sessionStart` | A session begins | no |
| `sessionEnd` | A session ends | no |
| `specialistStart` | A sub-agent is spawned | yes (specialist name) |
| `specialistStop` | A sub-agent ends | yes (specialist name) |
A hook's exit code decides what happens next: `0` continues, non-zero blocks the tool call (`beforeTool`) or surfaces an error (`afterTool`). Hook execution is recorded in the audit log; the audit is reachable from the agent's view of past actions, not from a dedicated `zero doctor` check.
> **Roadmap.** An in-UI hooks manager is on the backlog. Today you edit the JSON directly.
## 5. MCP — Model Context Protocol
Zero is both an **MCP client** (it can call external MCP servers) and an **MCP server** (other agents can call its tools).
### As a client — configure MCP servers in `config.json`
```json
{
"mcp": {
"servers": {
"docs": {
"type": "stdio",
"command": "docs-mcp",
"args": ["--port", "7777"]
},
"github": {
"type": "http",
"url": "https://api.example.com/mcp",
"headers": { "Authorization": "Bearer YOUR_TOKEN_HERE" }
}
}
}
}
```
Manage via CLI:
```bash
zero mcp add docs --type stdio -- docs-mcp --port 7777
zero mcp add github --type http --url https://api.example.com/mcp \
--header "Authorization=Bearer YOUR_TOKEN_HERE"
zero mcp list
zero mcp check docs
zero mcp remove github
zero mcp oauth login github
```
Servers are merged from user and project configs (project wins on conflicts). Token-bearing values in `config.json` are sent verbatim — there is no `${env:...}` expansion — so prefer one of:
- A wrapper script that sources the secret and execs the real command.
- A `--header` value produced by command substitution (`"Authorization=Bearer $(print-token)"`) in a private shell config that you keep out of git.
- A secret manager that injects the env var your MCP server reads on its own (the `command` and `args` then run inside that environment).
### As a server — expose Zero's tools to another agent
```bash
zero serve --mcp
```
The server speaks MCP over stdio. Configure it from the receiving side as a `stdio` server whose command is `zero serve --mcp`.
## 6. Plugins
A plugin is a self-contained directory that bundles tools, hooks, and skills for one capability. Plugins live at:
- User: `~/.config/zero/plugins/<id>/`
- Project: `./.zero/plugins/<id>/`
Each plugin has a `plugin.json` manifest:
```json
{
"id": "github-pr-review",
"name": "GitHub PR Review",
"description": "Adds review tools for GitHub PRs.",
"version": "1.0.0",
"tools": [
{ "name": "list_prs", "command": "./tools/list_prs.sh" }
],
"hooks": [
{ "name": "pre-merge-check", "event": "beforeTool", "command": "./hooks/pre-merge.sh" }
],
"skills": [
{ "path": "./skills/review-checklist/SKILL.md" }
]
}
```
Install and manage:
```bash
zero plugins add ./github-pr-review # copy into ~/.config/zero/plugins/ or ./.zero/plugins/
zero plugins list
zero plugins remove github-pr-review # alias: rm
```
A plugin is enabled by being present in the plugins directory and disabled by removing it (or by the user setting `"enabled": false` in its `plugin.json`). Plugins are not enabled or disabled by a CLI subcommand today.
Plugin commands run with the plugin directory as their working directory. Use relative paths; the loader resolves them at activation time.
> **Roadmap.** An in-UI plugins manager (browse, install, enable / disable) is on the backlog. Today you use the `zero plugins` CLI subcommands above. Skills declared inside a plugin's `plugin.json` are not yet merged into the `skill` tool's discovery (see section 3).
## 7. Configuration locations
Three layers, applied in order (later layers override earlier ones):
| Layer | Path | Notes |
| --- | --- | --- |
| Built-in defaults | compiled in | Lowest priority. |
| User config | `~/.config/zero/config.json` | Your machine. Never committed. |
| Project config | `./.zero/config.json` | The repo. Committed (or not, your call). |
| CLI flags | `--model`, `--mode`, ... | Highest priority, per-invocation. |
| Environment | `ZERO_*` | Provider commands, secrets, skills dir override. |
The user config holds things that should follow the user across projects (default provider, default model, theme). The project config holds things the team agreed on (provider catalog, sandbox policies, model restrictions).
The sandbox `additionalWriteRoots` key is **ignored in project config** by design — a checked-out repo cannot widen its own sandbox. Set it in the user config or pass `--add-dir` per-invocation.
## 8. End-to-end example
A team that wants every contributor's Zero to behave the same way commits:
- `AGENTS.md` — project conventions, build commands, do-not-edit lists.
- `.zero/config.json` — provider catalog, default model, allowed tools.
- `.zero/specialists/api-reviewer.md` — the team's PR-review specialist.
- `.zero/hooks.json` — block `rm -rf` and `git push --force` on `beforeTool`.
- `.zero/plugins/internal-tooling/` — a plugin that adds the team's internal CLI tools to the agent's toolset.
Each contributor adds only:
- `~/.config/zero/config.json` — their personal API keys, theme, default mode.
- `~/.config/zero/ZERO.md` — personal preferences that follow them across every project (see section 1).
- `~/.local/share/zero/skills/` — personal skills they keep across projects.
That's it. Run `zero` from the repo root and the agent has the team's full instruction set, every contributor's personal setup, and nothing else.
## 9. Reference
- [README](README.md) — install, quickstart, command reference.
- [docs/SPECIALISTS.md](docs/SPECIALISTS.md) — full specialist manifest spec.
- [docs/STREAM_JSON_PROTOCOL.md](docs/STREAM_JSON_PROTOCOL.md) — `zero exec` I/O contract.
- [docs/INSTALL.md](docs/INSTALL.md) — install from source or release.

To keep triage and review sustainable while the project stabilizes, please keep
your contribution flow to a size the core team can realistically work through:
- One issue per bug. File each defect as its own issue with its own
reproduction. Please do not bundle several unrelated findings into a single

- Keep only a few items open at a time. If you already have several issues or

```
The npm package is a small wrapper whose platform build (Linux and macOS on
x64/arm64, Windows on x64 — including the browser/terminal control helpers)
installs as an optional dependency straight from the npm registry — no install
scripts, no downloads outside npm. Bun, pnpm, and yarn work the same way with
no trust or approval steps. Installs that skip optional dependencies
(`--omit=optional`) still work: the wrapper fetches the binary from the
matching GitHub Release whenever it is missing. Windows on ARM runs the x64
build under emulation. See [docs/NPM_PACKAGING.md](docs/NPM_PACKAGING.md) for
how the package is put together.
The npm package installs a small wrapper plus the matching Zero binary for your
platform from GitHub Releases. It supports Linux, macOS, and Windows on x64 and
arm64.
### Bun
Bun does not run dependency lifecycle scripts by default, so the `postinstall`
that fetches the Zero binary is skipped and the first run fails with
`No native binary found next to the npm wrapper`.
The simplest fix is to trust the package after installing, which runs the
blocked postinstall. This works for project and global installs:
```bash
# project install
bun add @gitlawb/zero
bun pm trust @gitlawb/zero
# global install
bun add -g @gitlawb/zero
bun pm -g trust @gitlawb/zero
```
Alternatives: allow the postinstall up front by adding
`"trustedDependencies": ["@gitlawb/zero"]` to your project's package.json
before `bun add`, or run the installer manually
(`node node_modules/@gitlawb/zero/scripts/postinstall.mjs`) on Bun versions
that do not have `bun pm trust`.

### Code Quality and Security Checks
Before committing any changes, ensure all Go code quality and security checks pass. The `make` targets below pin each tool to this module's Go version, so they load correctly even when your default `go` toolchain is older — running the plain `go run ...@version` form yourself can select the tool module's own (older) toolchain and fail to load this module instead.
1. **Formatting**: Run `make fmt` (or `go fmt ./...`).
2. **Vetting**: Run `make vet` (or `go vet ./...`).
3. **Linting**: Run `make lint-static`.
4. **Vulnerability Scan**: Run `make vulncheck`.
Use the repository-managed targets rather than globally installed binaries:
the targets apply the module's required Go toolchain as well as the reviewed,
pinned tool versions.
The installed binaries land in `$GOBIN` when it is set, otherwise in
`$GOPATH/bin` (default `~/go/bin`). That directory must be on your `PATH` to
run them directly. If it isn't, add it:
```bash
gobin="$(go env GOBIN)"; [ -z "$gobin" ] && gobin="$(go env GOPATH)/bin"
case ":$PATH:" in *":$gobin:"*) ;; *) export PATH="$PATH:$gobin" ;; esac
```

npm 包是一个小型包装器,其平台构建(Linux 和 macOS 的 x64/arm64、Windows 的 x64,包含浏览器/终端控制辅助工具)作为可选依赖直接从 npm registry 安装——没有安装脚本,也不会从 npm 之外下载任何内容。Bun、pnpm 和 yarn 的行为完全一致,无需任何信任或批准步骤。跳过可选依赖的安装(`--omit=optional`)也能工作:只要二进制文件缺失,包装器就会从对应的 GitHub Release 下载。Windows on ARM 通过模拟运行 x64 构建。详见 [docs/NPM_PACKAGING.md](docs/NPM_PACKAGING.md)。
npm 包安装一个小型包装器以及与你平台匹配的 Zero 二进制文件(从 GitHub Releases 获取)。支持 Linux、macOS 和 Windows 的 x64 和 arm64。
### Bun
Bun 默认不运行依赖的生命周期脚本,因此获取 Zero 二进制文件的 `postinstall` 会被跳过,首次运行会失败并显示 `No native binary found next to the npm wrapper`。
最简单的解决方法是安装后信任该包,这会运行被阻止的 postinstall。项目安装和全局安装均适用:
```bash
# 项目安装
bun add @gitlawb/zero
bun pm trust @gitlawb/zero
# 全局安装
bun add -g @gitlawb/zero
bun pm -g trust @gitlawb/zero
```
其他方式:在 `bun add` 之前将 `"trustedDependencies": ["@gitlawb/zero"]` 添加到项目的 package.json 以提前允许 postinstall;或在不支持 `bun pm trust` 的旧版 Bun 上手动运行安装程序(`node node_modules/@gitlawb/zero/scripts/postinstall.mjs`)。

# Getting help with Zero
## Questions, setup help, configuration
Ask in [GitHub Discussions](https://github.com/Gitlawb/zero/discussions). Use
[Q&A](https://github.com/Gitlawb/zero/discussions/categories/q-a) so answers can
be marked and found by the next person.
The fastest way to a useful answer is to include:
- `zero --version` output
- your OS (Windows, macOS, Linux) and how you installed Zero (npm, install
script, source)
- the provider and model you are using (`zero providers list`)
- `zero doctor` output for setup problems
- the exact command you ran and the exact error text
## Bugs
If Zero does something wrong (crashes, wrong output, broken behavior), file a
[bug report](https://github.com/Gitlawb/zero/issues/new/choose). If you are not
sure whether it is a bug or a setup problem, start in Discussions and we will
promote it to an issue if it is one.
## Feature ideas
Start a thread in
[Ideas](https://github.com/Gitlawb/zero/discussions/categories/ideas). Zero is
in controlled development (see CONTRIBUTING.md), so discussing an idea first is
also the path to getting a PR accepted.
## Security issues
Never file a public issue or discussion. Report privately via
[GitHub Security Advisories](https://github.com/Gitlawb/zero/security/advisories/new)
(see SECURITY.md).

# Extending Zero
Zero is an open-source terminal coding agent. Out of the box it does the obvious things — read, edit, run, search — but the design point of the project is that **every surface is configurable**. This document is the user-facing guide for that configuration.
If you only want to *use* Zero, the [README](../README.md) is enough. This page is for the other three jobs:
1. Tell the agent about *your* project (drop an `AGENTS.md` in your repo).
2. Add new specialist sub-agents.
3. Wire Zero into the rest of your toolchain (MCP, skills, hooks, plugins).
## 1. Drop a project `AGENTS.md`
When Zero starts in a directory, it looks for project-level instructions and injects them into the system prompt. The lookup walks from your current working directory **up to the nearest git root** and reads the first matching file at each level — general rules at the repo root, more specific rules in sub-trees. Files are labeled with their directory in the prompt (e.g. `## Project guidelines (services/api/AGENTS.md)`).
Accepted file names, in priority order at each level:
| Path | Notes |
| --- | --- |
| `./AGENTS.md` | The classic spot — committed to your repo, shared with the team. |
| `./ZERO.md` | Brand-specific alias. Same format, lower priority. |
| `./.zero/AGENTS.md` | Project-local, hidden, gitignored. Personal notes that stay out of git. |
Matching is **case-insensitive** on the basename, so `AGENTS.md`, `Agents.md`, and `agents.md` resolve to the same file on Windows and macOS. The git-tracked filename in this repo is `AGENTS.md` — keep that on case-sensitive filesystems (Linux, the WSL filesystem, or a CI runner) to match what the loader looks for.
Both files use the same format. YAML frontmatter is optional; the markdown body is loaded as instructions for the agent. Zero reads the file once at session start, so changes take effect on the next `zero` launch — not mid-session.
```markdown
# Project conventions for <your project>
- Build with `make`, not `go build` directly.
- Tests live next to the source file (`foo_test.go` next to `foo.go`).
- Run `make lint` before opening a PR.
- Never edit files under `third_party/` — those are vendored.
```
Tips:
- Keep each file under ~8 KiB. Zero caps the **total** across all matched files at 32 KiB; everything past the cap is dropped.
- Re-state rules in the imperative voice: "Run `make lint`", not "you should consider running the linter".
- Don't put secrets, model IDs, or environment-specific paths in `AGENTS.md`. Use `config.json` for those.
- In a monorepo, drop a narrower `AGENTS.md` in each sub-tree (e.g. `services/api/AGENTS.md`). Zero picks those up automatically when you launch from inside the sub-tree.
- A YAML frontmatter block (`---\n...\n---`) at the top is preserved verbatim in the injected prompt but is not parsed for `globs:` or `alwaysApply:` scoping today — keep the body self-contained.
### Personal guidelines, across every project
For preferences that follow *you*, not a specific repo (tone, tooling habits, workflow), drop a `ZERO.md` in your user config directory: `~/.config/zero/ZERO.md` on Linux/macOS, `%AppData%\zero\ZERO.md` on Windows — the same directory as `config.json` and your personal specialists. Same format and 8 KiB cap as the project files above, and the same case-insensitive basename match.
This file is injected as its own `## User guidelines` section, before the project's `AGENTS.md`/`ZERO.md`, and is labeled as personal preference in the prompt: project guidelines are the later, more specific instruction and take precedence over it when the two conflict.
## 2. Custom specialists
Specialists are Zero's sub-agents. Three scopes, in priority order:
| Scope | Path | Shared? |
| --- | --- | --- |
| Built-in | compiled into Zero | yes — `worker`, `explorer`, `code-review` |
| User | `~/.config/zero/specialists/*.md` | no — your machine only |
| Project | `./.zero/specialists/*.md` | yes — the repo team |
Project overrides user overrides built-in when names collide.
A specialist is a markdown manifest with frontmatter and a system prompt:
```markdown
---
description: Reviews API changes for breaking-change risk and missing tests.
tools: read-only,plan
---
You review API changes. For every changed hunk in `internal/api/` or any file
that ends in `_api.go`:
1. Confirm the public signature is backward-compatible, or note the breaking
change explicitly with the migration path.
2. Confirm a corresponding test exists in `internal/api/*_test.go` and that
the new behaviour is exercised.
3. Flag any new exported symbol without a doc comment.
Reply with one JSON object per finding: `{"file", "line", "severity", "message", "fix"}`.
```
CLI management (the prompt is passed inline via `--prompt`):
```bash
zero specialist list
zero specialist show api-reviewer
zero specialist create api-reviewer \
--project \
--description "Reviews API changes" \
--tools read-only,plan \
--prompt "$(cat api-reviewer.md)"
zero specialist edit api-reviewer --project
zero specialist delete api-reviewer --project
zero specialist path # prints the resolved specialists directory
```
The full format spec (frontmatter fields, tool scopes, prompt conventions) is in [`docs/SPECIALISTS.md`](SPECIALISTS.md).
> **Roadmap.** An in-UI specialist manager (create / edit / delete / preview) is on the backlog. Today you use the `zero specialist` CLI subcommands above.
## 3. Skills
Skills are markdown instruction packs the agent can pull in on demand. Each skill is a directory containing a `SKILL.md`. Standalone project skill directories are not supported in this version (shared project-wide skills must go in `AGENTS.md` or as a hook). However, project plugins (section 6) may bundle skills, which are merged into the active run.
Discovery roots (earlier wins on name collisions):
1. **Primary Zero dir** — `$ZERO_SKILLS_DIR` if set, else `$XDG_DATA_HOME/zero/skills`, else `~/.local/share/zero/skills/`
2. **Shared multi-agent dir** — `~/.agents/skills/` when present (read-only discovery; never an install target)
3. **Plugin skill roots** — skills bundled by active plugins (section 6)
A missing directory is fine — Zero just omits it. Management commands (`zero skill add` / `zero skill remove`) always write to the primary Zero dir only; `list` / `info` search primary + `~/.agents/skills`. `skill info` reports lock source/hash when present and whether the on-disk `SKILL.md` has drifted from the recorded hash.
```text
~/.local/share/zero/skills/ # primary (install/remove target)
run-benchmarks/
SKILL.md
write-changelog/
SKILL.md
~/.agents/skills/ # optional shared multi-agent root
shared-review/
SKILL.md
```
`SKILL.md` format:
```markdown
---
description: Run the project's benchmark suite and summarize the deltas.
---
# Run benchmarks
1. `make bench` — captures the wall-clock and RSS before and after.
2. `benchstat before.txt after.txt` — diffs the two.
3. Report any regression > 5% with the function name and the previous value.
```
Only `name` and `description` are recognized in the frontmatter today. The `name` defaults to the directory name. Within a single skills root, duplicate names are resolved by lexicographic directory order. Across roots, Zero loads the primary directory first, then `~/.agents/skills`, then plugin skill roots; earlier roots win name collisions. Plugin-declared skills (section 6) are merged into the active agent run at plugin activation time, so bundled skills appear in the available skills list and can be loaded with the `skill` tool.
The `skill` tool lets the agent load any discovered skill by name (primary, agents, or plugin).
## 4. Hooks
Hooks fire shell commands on lifecycle events. Configure them in JSON:
- User: `~/.config/zero/hooks.json`
- Project: `./.zero/hooks.json`
```json
{
"enabled": true,
"hooks": [
{
"id": "block-rm-rf",
"event": "beforeTool",
"matcher": "bash",
"command": "/usr/local/bin/zero-hook-block-rmrf.sh",
"enabled": true
},
{
"id": "log-session",
"event": "sessionStart",
"command": "/usr/local/bin/zero-hook-log.sh",
"enabled": true
}
]
}
```
The `args` array (when present) is passed verbatim to `exec.CommandContext`. The actual hook payload — event name, matcher, tool call id, tool name, tool input, tool output, status — is delivered to the command as **JSON on stdin**, not via `${...}` substitution. A typical handler reads stdin and decides what to do:
```bash
#!/usr/bin/env bash
# /usr/local/bin/zero-hook-block-rmrf.sh
set -euo pipefail
payload="$(cat)"
if printf '%s' "$payload" | grep -q '"input":"[^"]*rm[[:space:]]+-rf'; then
echo "refusing rm -rf" >&2
exit 1
fi
```
Events the agent emits (in dispatch order):
| Event | Fires when | Matcher allowed? |
| --- | --- | --- |
| `beforeTool` | A tool is about to run | yes (tool name) |
| `afterTool` | A tool just returned | yes (tool name) |
| `sessionStart` | A session begins | no |
| `sessionEnd` | A session ends | no |
| `specialistStart` | A sub-agent is spawned | yes (specialist name) |
| `specialistStop` | A sub-agent ends | yes (specialist name) |
A hook's exit code decides what happens next: `0` continues, non-zero blocks the tool call (`beforeTool`) or surfaces an error (`afterTool`). Hook execution is recorded in the audit log; the audit is reachable from the agent's view of past actions, not from a dedicated `zero doctor` check.
> **Roadmap.** An in-UI hooks manager is on the backlog. Today you edit the JSON directly.
## 5. MCP — Model Context Protocol
Zero is both an **MCP client** (it can call external MCP servers) and an **MCP server** (other agents can call its tools).
### As a client — configure MCP servers in `config.json`
```json
{
"mcp": {
"servers": {
"docs": {
"type": "stdio",
"command": "docs-mcp",
"args": ["--port", "7777"]
},
"github": {
"type": "http",
"url": "https://api.example.com/mcp",
"headers": { "Authorization": "Bearer YOUR_TOKEN_HERE" }
}
}
}
}
```
Manage via CLI:
```bash
zero mcp add docs --type stdio -- docs-mcp --port 7777
zero mcp add github --type http --url https://api.example.com/mcp \
--header "Authorization=Bearer YOUR_TOKEN_HERE"
zero mcp list
zero mcp check docs
zero mcp remove github
zero mcp oauth login github
```
Servers are merged from user and project configs (project wins on conflicts). Token-bearing values in `config.json` are sent verbatim — there is no `${env:...}` expansion — so prefer one of:
- A wrapper script that sources the secret and execs the real command.
- A `--header` value produced by command substitution (`"Authorization=Bearer $(print-token)"`) in a private shell config that you keep out of git.
- A secret manager that injects the env var your MCP server reads on its own (the `command` and `args` then run inside that environment).
Project MCP config remains supported for shared team servers, but a project layer
that changes an existing server's target (`url`, `command`, or `args`) does not
inherit user credentials. Clear or replace `headers`, `env`, or `oauth` explicitly,
or use a new server name. OAuth tokens are bound to the resolved server identity,
so changing a server target can require `zero mcp oauth login <server>` again.
OAuth server names ending in `.<32 hex chars>` are reserved for token storage.
### As a server — expose Zero's tools to another agent
```bash
zero serve --mcp
zero serve --mcp -C /path/to/workspace
zero serve --mcp --add-dir /path/to/extra
```
The server speaks MCP over stdio. Configure it from the receiving side as a `stdio` server whose command is `zero serve --mcp`.
`-C/--cwd` sets the workspace root exposed as MCP resources and used by core tools. `--add-dir` (repeatable) widens that resource/tool scope beyond the workspace without granting the sandbox temp roots used by interactive runs.
## 6. Plugins
A plugin is a self-contained directory that bundles tools, hooks, and skills for one capability. Plugins live at:
- User: `~/.config/zero/plugins/<id>/`
- Project: `./.zero/plugins/<id>/`
Each plugin has a `plugin.json` manifest:
```json
{
"id": "github-pr-review",
"name": "GitHub PR Review",
"description": "Adds review tools for GitHub PRs.",
"version": "1.0.0",
"tools": [
{ "name": "list_prs", "command": "./tools/list_prs.sh" }
],
"hooks": [
{ "name": "pre-merge-check", "event": "beforeTool", "command": "./hooks/pre-merge.sh" }
],
"skills": [
{ "path": "./skills/review-checklist/SKILL.md" }
]
}
```
Install and manage:
```bash
zero plugins add ./github-pr-review # copy into ~/.config/zero/plugins/ or ./.zero/plugins/
zero plugins list
zero plugins info github-pr-review # show manifest path, enabled state, lock metadata
zero plugins remove github-pr-review # alias: rm
```
A plugin is enabled by being present in the plugins directory and disabled by removing it (or by the user setting `"enabled": false` in its `plugin.json`). Plugins are not enabled or disabled by a CLI subcommand today.
Plugin commands run with the plugin directory as their working directory. Use relative paths; the loader resolves them at activation time.
> **Roadmap.** An in-UI plugins manager (browse, install, enable / disable) is on the backlog. Today you use the `zero plugins` CLI subcommands above.
## 7. Configuration locations
Five configuration sources, in precedence order (later sources override earlier ones):
| Source | Path / Key | Notes |
| --- | --- | --- |
| Built-in defaults | compiled in | Lowest priority. |
| User config | `~/.config/zero/config.json` | Your machine. Never committed. |
| Project config | `./.zero/config.json` | The repo. Committed (or not, your call). |
| Environment | `ZERO_*` | Provider commands, secrets, skills dir override. |
| CLI flags | `--model`, `--mode`, ... | Highest priority, per-invocation. |
The user config holds things that should follow the user across projects (default provider, default model, theme). The project config holds things the team agreed on (provider catalog, sandbox policies, model restrictions).
The sandbox `additionalWriteRoots` key is **ignored in project config** by design — a checked-out repo cannot widen its own sandbox. Set it in the user config or pass `--add-dir` per-invocation.
## 8. End-to-end example
A team that wants every contributor's Zero to behave the same way commits:
- `AGENTS.md` — project conventions, build commands, do-not-edit lists.
- `.zero/config.json` — provider catalog, default model, allowed tools.
- `.zero/specialists/api-reviewer.md` — the team's PR-review specialist.
- `.zero/hooks.json` — block `rm -rf` on `beforeTool`.
- `.zero/plugins/internal-tooling/` — a plugin that adds the team's internal CLI tools to the agent's toolset.
Each contributor adds only:
- `~/.config/zero/config.json` — their personal API keys, theme, default mode.
- `~/.config/zero/ZERO.md` — personal preferences that follow them across every project (see section 1).
- `~/.local/share/zero/skills/` — personal skills they keep across projects.
That's it. Run `zero` from the repo root and the agent has the team's full instruction set, every contributor's personal setup, and nothing else.
## 9. Reference
- [README](../README.md) — install, quickstart, command reference.
- [docs/SPECIALISTS.md](SPECIALISTS.md) — full specialist manifest spec.
- [docs/STREAM_JSON_PROTOCOL.md](STREAM_JSON_PROTOCOL.md) — `zero exec` I/O contract.

# How Zero Works
This document explains Zero's architecture at a high level: the layers, module
boundaries, data flow, and runtime concepts behind the interactive TUI and the
headless `zero exec` mode.
It is written as a progressive map: each high-level section introduces the
concepts you need for orientation, then points to the later section that explains
the mechanics in more detail.
## Big Picture
Zero is a Go CLI application with two main user-facing surfaces:
- **Interactive TUI** (`zero`): a Bubble Tea application that renders chat,
tool cards, permission prompts, model/provider pickers, and session controls.
- **Headless exec** (`zero exec ...`): a scriptable command runner that uses the
same agent loop and tools, but writes text, JSON, or stream-JSON events.
Both surfaces converge on the same core agent runtime:
```mermaid
flowchart TD
User[User / automation] --> CLI[cmd/zero -> internal/cli]
CLI --> TUI[Interactive TUI<br/>internal/tui]
CLI --> Exec[Headless exec<br/>internal/cli/exec.go]
CLI --> ACP[ACP / editor bridge<br/>internal/acp]
TUI --> Agent[Agent loop<br/>internal/agent]
Exec --> Agent
ACP --> Agent
Agent --> Provider[Provider runtime<br/>internal/zeroruntime.Provider]
Provider --> APIs[OpenAI / Anthropic / Gemini / compatible APIs]
Agent --> Registry[Tool registry<br/>internal/tools.Registry]
Registry --> CoreTools[Core tools<br/>read/edit/shell/search/plan]
Registry --> MCP[MCP tools<br/>internal/mcp]
Registry --> Specialists[Specialist tools<br/>internal/specialist]
Registry --> Plugins[Plugin tools<br/>internal/plugins]
Registry --> LocalControl[Browser / terminal / desktop helpers]
Agent --> Sandbox[Permission + sandbox engine<br/>internal/sandbox]
Agent --> Hooks[Hooks dispatcher<br/>internal/hooks]
Agent --> Sessions[Session event store<br/>internal/sessions]
```
The important split is:
- `internal/tui` is the **presentation layer**. For the mechanics, see
[Presentation Layer: Bubble Tea TUI](#presentation-layer-bubble-tea-tui) and
[How the TUI and Agent Loop Connect](#how-the-tui-and-agent-loop-connect).
- `internal/agent` is the **reasoning/tool loop**. For the per-turn mechanics,
see [Agent Loop](#agent-loop), [Tool Execution Lifecycle](#tool-execution-lifecycle),
and [Context Budget and Compaction](#context-budget-and-compaction).
- `internal/tools`, `internal/sandbox`, and provider packages are the **runtime
capability layer**. For the details, see [Runtime Provider Layer](#runtime-provider-layer),
[Tools and Capabilities](#tools-and-capabilities), and
[Permission and Sandbox Model](#permission-and-sandbox-model).
- `internal/sessions` is the **durable event log** used for resume, fork,
rewind, sub-agents, and history. See [Session Storage and History](#session-storage-and-history).
## Architecture Spine
The easiest way to understand Zero is not as a set of independent packages, but
as one spine with several mechanisms attached to it:
```mermaid
flowchart LR
Surface[Surface<br/>TUI / exec / ACP] --> Run[Run request<br/>prompt + runtime options]
Run --> Agent[Agent loop<br/>turns, tools, recovery]
Agent --> Capabilities[Capabilities<br/>providers + tools + sandbox]
Capabilities --> Events[Runtime events<br/>text, tool calls, permissions, usage]
Events --> Surface
Events --> Sessions[Session log<br/>resume, fork, rewind, history]
Config[Config / guidelines / skills] --> Run
Extensions[MCP / specialists / plugins / hooks] --> Capabilities
```
The **TUI + agent loop** is the main story because it explains the normal user
experience: type a prompt, watch the model stream, approve tool use, see file
changes, and receive a final answer. Other mechanisms are still important, but
most of them attach to the same spine:
| Mechanism | Where it attaches | What it changes |
| --- | --- | --- |
| Config, provider profiles, model registry | Before a run starts | Which provider/model is used and what defaults apply. |
| Project/user guidelines, skills, specialists context | Prompt construction | What instructions and available capabilities the model sees. |
| Tool registry, MCP, plugins, local-control helpers | Capability layer | Which actions the model may request. |
| Permission policy, sandbox, command-prefix grants | Tool execution | Whether a requested action can run, needs approval, or is denied. |
| Hooks | Tool lifecycle | Optional before/after observers or blockers around tool calls. |
| Sessions, checkpoints, compaction metadata | Event persistence/context | What can be resumed, forked, rewound, or summarized for later turns. |
| Stream-JSON | Surface layer | How the same runtime events are emitted for automation instead of rendered in the TUI. |
So this document focuses first on the TUI/agent-loop bridge, then explains the
supporting mechanisms in terms of where they connect to that bridge.
Use this as the reading path:
| If you see this concept in a high-level flow | Read this detail section |
| --- | --- |
| Surface submits a run | [Startup Flow](#startup-flow), then [How the TUI and Agent Loop Connect](#how-the-tui-and-agent-loop-connect) |
| Agent builds context and advances turns | [Agent Loop](#agent-loop) |
| “Maybe compact context” | [Context Budget and Compaction](#context-budget-and-compaction) |
| Model requests a tool | [Tool Execution Lifecycle](#tool-execution-lifecycle), then [Tools and Capabilities](#tools-and-capabilities) |
| Tool needs approval or sandbox access | [Permission and Sandbox Model](#permission-and-sandbox-model) |
| Events appear in the UI or stream-JSON | [How the TUI and Agent Loop Connect](#how-the-tui-and-agent-loop-connect), [Stream-JSON Protocol](#stream-json-protocol) |
| Resume, fork, rewind, or sub-agent history | [Session Storage and History](#session-storage-and-history) |
## Main Packages
The sections above describe the architecture in concepts. If you want to connect
those concepts to implementation details, use this table as the code map before
reading the deeper flows below.
| Package | Role |
| --- | --- |
| `cmd/zero` | Tiny binary entrypoint; calls `internal/cli.Run`. |
| `internal/cli` | Command parsing, config resolution, provider creation, registry setup, TUI/exec/ACP launch paths. |
| `internal/tui` | Bubble Tea model/update/view code, transcript rendering, composer, prompts, slash commands, setup wizard. |
| `internal/agent` | Core loop that sends messages to the model, streams output, executes tools, handles permissions, compaction, retries, and final answers. |
| `internal/zeroruntime` | Provider-neutral message, tool-call, stream, usage, and image types. Providers implement `Provider.StreamCompletion`. |
| `internal/providers` | Factory that turns a resolved provider profile into an OpenAI, Anthropic, Gemini, Codex, or compatible provider adapter. |
| `internal/tools` | Tool interface, registry, core read/write/shell/network tools, local-control wrappers, tool safety metadata, redaction, output ceilings. |
| `internal/sandbox` | Permission policy, path/network checks, grant store, command-prefix approvals, and platform sandbox backends. |
| `internal/sessions` | Local append-only session storage: `metadata.json` + `events.jsonl`. |
| `internal/config` | User/project config resolution, active provider, preferences, sandbox/tool settings. |
| `internal/mcp` | MCP server config, client runtime, permission store, and MCP tool registration. |
| `internal/specialist` / `internal/swarm` | Sub-agent manifests and team/member orchestration exposed as tools. |
| `internal/localcontrol` / `internal/browser` | Runtime helpers used by config-gated local-control tool wrappers. |
| `internal/plugins` / `internal/skills` / `internal/hooks` | Extension surfaces loaded into the agent context, tool registry, or tool lifecycle. |
| `internal/streamjson` | Machine-readable protocol for `zero exec --input-format/--output-format stream-json`. |

The TUI owns terminal interaction. It tracks composer state, transcript rows,
scrolling, permission dialogs, model/provider pickers, setup wizard state, and
visual updates. When the user submits a prompt, the TUI builds `agent.Options`
with callbacks like `OnText`, `OnToolCall`, `OnToolResult`, `OnPermission`,
`OnAskUser`, and `OnUsage`. Those callbacks convert runtime events into visible
transcript rows and session events.
### Headless exec (`zero exec`)
```mermaid

A[Parse exec flags] --> B[Resolve config + provider]
B --> C[Build tool registry]
C --> D[Resolve prompt / stream-json input / images]
D --> E[Prepare or resume session]
E --> F[Create stream-json/text/json writer]
F --> G[agent.Run]
G --> H[Write final output and exit code]
```
`zero exec` uses the same `agent.Run` loop as the TUI, but without interactive
terminal state. It can persist sessions, resume/fork existing sessions, run in
stream-JSON mode for automation, and always requires a stronger completion
signal so a no-tool assistant response is not treated as success while work is
still pending.
## Agent Loop
The core loop lives in `internal/agent.Run`. Conceptually, every turn follows
this cycle:
```mermaid
flowchart TD
Start[Build system prompt + user prompt] --> Expose[Partition visible tools]
Expose --> Compact[Maybe compact context]
Compact --> Request[Send CompletionRequest to provider]
Request --> Stream[Collect streamed text, reasoning, usage, tool calls]
Stream --> HasTools{Tool calls?}
HasTools -- No --> FinalCheck{Final answer acceptable?}
FinalCheck -- Yes --> Done[Return Result]
FinalCheck -- No --> Nudge[Append user nudge and continue]
HasTools -- Yes --> Execute[Execute tool calls]
Execute --> Permission[Permission / sandbox / hooks]
Permission --> ToolResult[Append tool result messages]
ToolResult --> Diagnostics[Post-edit diagnostics / self-correct]
Diagnostics --> Expose
```
Key responsibilities of the loop:
1. **Build prompt state** — combines the system prompt, project/user guidelines,
loaded skills/specialist instructions, the current user prompt, and images. The
resulting message list is the model-facing context that later tool results are
appended to. Resumed session history is replayed by the caller before a new run,
not passed as a separate `agent.Run` history field.
2. **Expose tools** — starts from the registry built by the CLI, then filters
tool definitions by permission mode, enabled or disabled filters, and
deferred-loading rules. Tool schemas also count toward context budget, so they
matter for compaction decisions.
3. **Call provider** — sends a provider-neutral `zeroruntime.CompletionRequest`.
4. **Stream events** — forwards text, reasoning, tool-call deltas, and usage to
the caller via callbacks.
5. **Execute tools** — decodes tool arguments, checks filters, applies
permissions and sandbox policy, dispatches hooks, runs the registered tool,
redacts output, and appends a tool message. See
[Tool Execution Lifecycle](#tool-execution-lifecycle).
6. **Recover and guard** — handles malformed tool calls, repeated failures,
empty turns, context pressure, stream reconnect/retry, and max-turn fallback.
Context pressure is handled by [Context Budget and Compaction](#context-budget-and-compaction).
7. **Finalize** — returns a final answer or a structured incomplete/stop reason.
The model never directly mutates the workspace. It asks for tool calls; Zero
validates and executes those calls through the registry, permission policy, and
sandbox engine.
## Tool Execution Lifecycle
A tool call is part of the model conversation, not a side channel that bypasses
it. The model proposes an action, Zero decides whether that action is allowed to
run, the tool returns a structured result, and that result becomes context for the
next provider request.
```mermaid

Agent-->>Surface: OnToolResult callback
Agent->>Transcript: append tool result message
end
Agent->>Model: next request includes prior assistant tool_call + tool result
Model-->>Agent: continue with more tools or final answer
```
Conceptually, one requested tool goes through these phases:
1. **Proposal** — the provider streams assistant content and may emit one or more
tool calls. Zero can show the partial tool arguments in the TUI while they are
still streaming, but nothing has executed yet.
2. **Decode and gate** — the agent validates JSON arguments, checks whether the
tool is enabled, applies permission mode, asks the sandbox engine about path,
network, shell, or command-prefix constraints, and may invoke permission
callbacks.
3. **Execute** — the selected registry entry runs locally, through MCP, as a
specialist/sub-agent, or through a plugin/local-control helper. Hooks can run
before or after this step.
4. **Normalize result** — Zero turns the outcome into an agent `ToolResult`: a
success, failure, denial, cancellation, timeout, or validation error with
output/metadata that may be redacted or truncated.
5. **Append to context** — the result is appended as a tool-result message paired
with the assistant tool call. The next model request includes that result, so
the model can inspect it and decide what to do next.
6. **Render and persist** — the result is surfaced to the TUI, stream-JSON
writer, or ACP client. TUI and exec record rich tool/session events for
resume/history; ACP currently persists conversational messages and streams
tool/permission updates to the client.
Tool success and failure are both informative context. A successful `read_file`
result gives the model file contents; a failed `edit_file` result gives the model
an error such as “old string not found”; a denied shell command tells the model
that the action is not currently permitted. The model is expected to use that
feedback to continue, choose another tool, ask the user, or explain the blocker.
The judgement that “information is sufficient” is made by the model, not by the
TUI. Zero controls the loop mechanics: it keeps appending messages, enforces
safety, retries or nudges around malformed/empty/incomplete turns, and stops on
hard limits. But the semantic decision to call another tool versus produce a
final answer comes from the next provider response. In other words:
```mermaid
flowchart TD
Result[Tool result appended to conversation] --> Next[Next provider request]
Next --> Decide{Model response}
Decide -- More information/action needed --> MoreTools[Request another tool]
MoreTools --> Result
Decide -- User input needed --> AskUser[Call ask_user or explain question]
AskUser --> Result
Decide -- Enough information --> Final[Final assistant answer]
Decide -- Invalid / empty / unsafe --> Guard[Agent guardrail, retry, denial, or stop reason]
Guard --> Next
```
This is why tool output is usually more than UI decoration. It is part of the
working memory for the next model turn, subject to context-window pressure and
compaction. The TUI may summarize or prettify it for the user, but the agent loop
also stores the machine-facing result that the model sees.
## Context Budget and Compaction
The `Maybe compact context` step in the agent-loop diagram is Zero's context-window
pressure valve. It is not a separate memory engine; it rewrites the current
model-facing conversation so the next provider request fits within the configured
context window.
Compaction is enabled only when the run knows a positive `ContextWindow`. When it
is enabled, the loop does this near the top of each turn:
```mermaid
flowchart TD
Tools[Partition visible tools] --> Estimate[Estimate messages + tool-definition tokens]
Estimate --> Under{Under threshold?}
Under -- Yes --> Keep[Keep context as-is]
Under -- No --> Grown{Grown past low-water mark?}
Grown -- No --> Keep
Grown -- Yes --> Prune[Prune stale large tool outputs]
Prune --> Recheck{Back under threshold?}
Recheck -- Yes --> KeepPruned[Use pruned context]
Recheck -- No --> Summarize[Summarize oldest middle]
Summarize --> Replace[system messages + summary + recent suffix]
```
The trigger is intentionally approximate:
- Zero estimates request size using message text, images, tool-call arguments, and
the tool definitions advertised on that turn.
- The proactive threshold is roughly **two-thirds of the context window**.
- Provider usage from completed turns is used to calibrate the rough estimate over
time, so the budget gauge and compaction decision track the provider more
closely after a few turns.
- A low-water mark prevents the loop from re-summarizing the same already-compacted
history on every turn.
When compaction actually runs, it tries to preserve the parts most likely to be
needed by the model:
- leading system messages stay verbatim;
- the most recent turns stay verbatim (`CompactionPreserveLast`, defaulting to the
agent's normal preserve count);
- the preserved suffix is widened to a provider-valid turn boundary so tool-result
messages are not replayed without their corresponding assistant tool call;
- the older middle is summarized into one user-role message labeled
`[Summary of earlier conversation]`;
- structured state that should not be paraphrased away, such as active plan/loaded
skill state, is preserved alongside the prose summary.
There are two compaction paths:
1. **Proactive compaction** runs before the provider call when the estimated
request is over threshold.
2. **Reactive compaction** runs after a provider returns a context-limit style
error. Zero compacts once and retries that same turn; if the provider still
rejects the request, the error is surfaced rather than looping forever.
Compaction failures are conservative. If the summarizer fails during proactive
compaction, Zero keeps the original messages and tries to continue. It does not
drop conversation history just to make room.
## Presentation Layer: Bubble Tea TUI
`internal/tui` is a Bubble Tea application. The usual Bubble Tea shape applies:
```mermaid
flowchart LR
Init[model.Init] --> Update[model.Update]
Update --> View[model.View]
View --> Terminal[Terminal frame]
Terminal --> Msg[tea.Msg: key, mouse, window, agent event]
Msg --> Update
```
The TUI is intentionally not the agent brain. It is responsible for:
- collecting user input from the composer;
- rendering assistant text, reasoning, tool cards, permissions, plans, usage,
files, and sidebars;
- handling slash commands and modal surfaces;
- converting agent callbacks into Bubble Tea messages;
- persisting visible session events;
- allowing live provider/model/permission changes.
When a prompt is submitted, the TUI starts a background command that invokes
`agent.Run`. Streaming callbacks send messages back into the Bubble Tea update
loop, so rendering remains responsive while the agent is working.
## How the TUI and Agent Loop Connect
A common source of confusion is that Zero has two event loops running at once:
1. **Bubble Tea loop** — owns terminal input, in-memory UI state, and frames.
2. **Agent loop** — owns model turns, tool execution, permissions, retries, and
stop conditions.
They are connected by `tea.Cmd` and `agent.Options` callbacks. The TUI never
runs provider/tool logic directly inside `Update`; instead, submit handling gates
and dispatches a prompt, the TUI starts a background command, and that command
calls `agent.Run` with callbacks that send runtime events back to the Bubble Tea
program. Function names in this section are illustrative code anchors, not API
boundaries.
```mermaid
sequenceDiagram

User->>TUI: type prompt / press Enter
TUI->>TUI: validate/gate submit and append visible user row
TUI->>Cmd: launch tea.Cmd with runID + cancellable context

Cmd->>Store: batch session events for resume/history
Cmd-->>TUI: final agentResponseMsg
TUI->>TUI: mark run complete, flush rows/events, unlock composer
```
In the TUI path, the same event can have three representations:
| Runtime thing | Agent representation | TUI representation | Session representation |
| --- | --- | --- | --- |
| Assistant text | streamed provider text forwarded through `OnText` | incremental assistant row text | assistant message event |
| Reasoning preview | `OnReasoning` callback | collapsible/preview reasoning row | usually not the same as final assistant text |
| Tool call | `agent.ToolCall` from collected provider stream | tool card, specialist card, or plan panel update | `EventToolCall` |
| Tool result | `agent.ToolResult` | result card/status, changed files, plan/specialist updates | `EventToolResult` |
| Permission prompt/audit | `PermissionRequest` / `PermissionEvent` | modal prompt or permission row | permission request/decision events |
| Usage/context | provider usage + measured context | context gauge / usage metadata | usage event |
### One interactive turn, end to end
For a normal prompt in the interactive TUI:
1. Submit handling validates composer state and command gates, then dispatches
the prompt to the launch path.
2. The launch path appends immediate UI rows, creates a cancellable run context,
and starts `runAgent` as a `tea.Cmd`; run bookkeeping assigns the `runID` used
to correlate later events.
3. `runAgentWithOptions` copies the current UI-controlled runtime choices into
`agent.Options`: provider/model labels, permission mode, cwd, session ID,
images, registry, response style, context window, and self-correction hooks.
4. The command wraps agent callbacks. For example:
- `OnText` sends incremental assistant text into the TUI message sink.
- `OnToolCallStart` / `OnToolCallDelta` show live tool-argument streaming.
- `OnToolCall` creates visible tool rows and appends session events.
- `OnToolResult` creates result rows, updates plan/specialist side panels, and
records changed files.
- `OnPermissionRequest` sends a prompt to the TUI and blocks the agent loop
until the user answers or the run context is cancelled.
- `OnAskUser` does the same for model-initiated clarification questions.
5. `agent.Run` builds provider-neutral messages and tool definitions, streams a
provider response, executes any requested tools through the registry/sandbox,
appends tool results back into the model conversation, and repeats until it has
a final answer or a stop condition.
6. When `agent.Run` returns, the command emits `agentResponseMsg`. The Bubble Tea
loop marks the run complete, flushes queued rows/session events, updates usage
and file state, and re-enables the composer.
The important architectural point: **the TUI is stateful and reactive, but the
agent loop is the source of runtime truth for model/tool progress**. Presentation
state is derived from callback events and persisted session events; workspace
changes happen only through tools executed by the agent runtime.
### Feature flows use the same bridge
For one interactive turn, the supporting systems do not run beside the TUI/agent
loop; they run inside or around it:
```mermaid
flowchart TD
Submit[TUI submit] --> Options[Build agent.Options]
Options --> Context[Assemble context<br/>config, guidelines, history, skills]
Context --> ProviderCall[Provider stream]
ProviderCall --> StreamEvents[Text/reasoning/tool-call events]
StreamEvents --> Render[TUI render callbacks]
ProviderCall --> ToolCall{Tool call?}
ToolCall -- No --> Final[Final response]
ToolCall -- Yes --> ToolGate[Tool gate<br/>filters, permissions, sandbox]
ToolGate --> HooksBefore[beforeTool hooks]
HooksBefore --> Execute[Tool / MCP / specialist / plugin]
Execute --> HooksAfter[afterTool hooks]
HooksAfter --> ToolResult[Tool result message]
ToolResult --> Persist[Session events]
ToolResult --> Context
Final --> Persist
Persist --> Resume[Resume / fork / rewind / parent metadata]
```
Most interactive features are variations of that same bridge rather than separate
architectures:
- **Slash commands** either mutate TUI state directly (`/model`, `/permission`,
`/help`) or start short `tea.Cmd` jobs that later return a message to `Update`
(`/doctor`, `/search`, `/compact`, session commands).
- **Permissions** sit between a model-requested tool call and actual execution:
the agent blocks on `OnPermissionRequest`, the TUI surfaces a modal and sends
the decision back through a channel, and the session log records the
request/decision events.
- **Plans, specialists/sub-agents, and ask-user prompts** all follow the same
runtime pattern: the model requests a capability, the agent records the
call/result in its conversation, and the TUI mirrors the visible state as plan
panels, specialist cards, or question forms. Specialist session metadata can
carry parent/root and sub-agent/spec fields, with richer linkage depending on
the specialist or swarm path.
- **Streaming tool writes** start as provider tool-call deltas before execution;
the TUI shows the arguments live, then replaces/augments them with the actual
`ToolResult` after the tool runs.
- **Compaction** is an agent-loop context-management step; the TUI may show that
it happened, but the purpose is to keep the next provider request within budget.
- **Stream-JSON** is another surface over the same callbacks: `zero exec`
serializes the events as JSON protocol events instead of Bubble Tea views.
So a feature-specific deep dive should usually explain: what user event starts it,
which `tea.Msg`/callback carries it, which agent/tool event is authoritative, and
which session events make it resumable.
## Runtime Provider Layer
Providers are hidden behind this interface in `internal/zeroruntime`:
```go
type Provider interface {
StreamCompletion(ctx context.Context, request CompletionRequest) (<-chan StreamEvent, error)
}
```
The agent loop only knows about provider-neutral messages, tool definitions,
stream events, reasoning blocks, images, and token usage. Provider adapters in
`internal/providers/*` translate those neutral types to provider-specific APIs:
- OpenAI and OpenAI-compatible APIs;
- Anthropic and Anthropic-compatible APIs;
- Gemini;
- Codex / ChatGPT OAuth-backed runtime.
`internal/providers.New` resolves the configured model through the model
registry/catalog, normalizes API model IDs and base URLs, attaches API keys or
OAuth resolvers, and returns the concrete adapter.
## Tools and Capabilities
Tools implement a common interface and are registered by name in
`internal/tools.Registry`.
```mermaid
flowchart TD
AgentToolCall[Tool call from model] --> Decode[Decode JSON args]
Decode --> Filter[Enabled/disabled + permission-mode filter]
Filter --> Precheck[Pre-permission rejecters]
Precheck --> SandboxEval[Sandbox Evaluate]
SandboxEval --> Prompt{Needs user approval?}
Prompt -- Yes --> Decision[Permission callback]
Prompt -- No --> Run[Registry.RunWithOptions]
Decision --> Run
Run --> Redact[Redact secrets]
Redact --> Budget[Token-aware semantic output budget]
Budget --> Ceiling[Existing hard byte ceiling]
Ceiling --> Message[Return one tool result to model]
```
Oversized results use deterministic, provider-neutral estimated-token budgets.
Policies retain useful structure for files, search matches, tests, process logs,
diffs, and worker conclusions; tools without a declared category use a UTF-8-safe
head/tail fallback. The estimate is intentionally conservative for non-ASCII
text and is not exact provider tokenization. Existing byte ceilings remain the
authoritative safety limit. When the existing spill mechanism can persist the
complete redacted text received by the budgeting layer, the result includes its
safe spill reference. This does not imply capture of subprocess bytes already
discarded by a tool's established internal buffer.
Core tool groups include:
- **Read-only tools**: file reads, directory listing, glob, grep, LSP navigation,
skills, `ask_user`, permission requests.
- **Write tools**: `write_file`, `edit_file`, `apply_patch`, `update_plan`.
- **Shell tools**: `exec_command`, `write_stdin`, legacy `bash`.
- **Network tools**: `web_fetch` and optional web search backend.
- **Local-control tools**: config-gated wrappers for browser, terminal, desktop,
and artifact helpers backed by packages such as `internal/localcontrol` and
`internal/browser`.
- **Extension tools**: MCP tools, specialists/sub-agents, swarm tools, plugins.
Tool definitions include safety metadata: side-effect class, permission level,
reason, and whether prompt-gated tools are advertised in auto-like modes. The
agent uses this metadata plus per-turn filters and deferred-loading state to
choose which registered tools the model can see and whether a call can run
immediately.
## Permission and Sandbox Model
Zero has two related but separate checks:
1. **Tool permission metadata** says whether a tool is allowed, denied, or needs
approval.
2. **Sandbox policy** evaluates the actual request: path scope, network access,
destructive shell patterns, explicit escalation, persistent/session grants,
and platform isolation availability.
```mermaid
flowchart TD
Call[Tool call] --> Safety[Tool Safety metadata]
Call --> Scope[Workspace/additional roots scope]
Safety --> Engine[Sandbox Engine Evaluate]
Scope --> Engine
Engine --> Allow[Allow]
Engine --> Prompt[Prompt user]
Engine --> Deny[Deny]
Prompt --> Grant[Turn/session/persistent grant]
Grant --> Execute[Execute tool]
Allow --> Execute
Deny --> Result[Return denied tool result]
```
The sandbox engine can:
- auto-allow workspace writes for safe file-edit tools;
- block reads/writes outside the allowed scope;
- prompt for recoverable outside-workspace access;
- deny or prompt for network depending on policy;
- detect destructive shell commands;
- run shell commands through a platform backend when available;
- remember session or persistent grants;
- support narrow command-prefix approvals.
The user-facing TUI and `zero exec` mode both route permission requests through
callbacks, but the TUI can show interactive modals while headless mode generally
returns non-interactive fallback behavior unless a protocol/client handles it.
## Session Storage and History
Sessions live locally under Zero's data directory. A session directory contains:
- `metadata.json` — session ID, title, cwd, provider/model, parent/root IDs,
spec/sub-agent fields, timestamps, and event count.
- `events.jsonl` — append-only event log with messages, tool calls/results,
permissions, usage, checkpoints, forks, compaction, and specs. TUI and exec use
the richer event stream; ACP currently records conversational message history
while streaming tool and permission updates to the client.
```mermaid
flowchart LR
TUI[TUI callbacks] --> Store[internal/sessions.Store]
Exec[exec recorder] --> Store
Store --> Metadata[metadata.json]
Store --> Events[events.jsonl]
Events --> Resume[resume]
Events --> Fork[fork]
Events --> Rewind[rewind/checkpoints]
Events --> Children[parent/root metadata]
```
This is why sessions can be resumed, forked, rewound, and inspected without a
remote service. Zero stores the local event history; providers only receive the
messages needed for the current completion request.
## Stream-JSON Protocol
`zero exec --output-format stream-json` emits newline-delimited JSON events for
integrations and CI. The protocol is implemented in `internal/streamjson` and is
specified in [STREAM_JSON_PROTOCOL.md](STREAM_JSON_PROTOCOL.md).
Common output event types include:
- `run_start`, `text`, `reasoning`, `tool_call`, `tool_result`;
- `permission`, `permission_request`, `permission_decision`;
- `checkpoint`, `restore`, `usage`, `final`, `warning`, `error`, `run_end`.
Input stream-JSON can provide `prompt` or `message` events and image payloads.
The CLI parses those events, resolves a single prompt, validates/decodes images,
and passes the result into the same agent loop used everywhere else.
## Extensibility Flow
Zero's extension surfaces are loaded before the agent loop starts:
```mermaid
flowchart TD
Config[Config resolution] --> Registry[Tool registry]
Registry --> Core[Core tools]
Registry --> MCP[MCP server tools]
Registry --> Specialist[Specialist / Task tools]
Registry --> Plugin[Plugin tools]
Config --> Prompt[System prompt context]
Prompt --> Guidelines[AGENTS.md / ZERO.md]
Prompt --> Skills[Skills list]
Prompt --> SpecialistContext[Specialist descriptions]
ToolLifecycle[Tool lifecycle] --> Hooks[beforeTool / afterTool hooks]
```
- **Project/user guidelines** become prompt context.
- **Skills** are instruction packs the model can load on demand.
- **Specialists** are sub-agents callable through the `Task` tool.
- **MCP servers** contribute external tools.
- **Plugins** can add tools, hooks, and skill roots. Bootstrap always registers a
multi-root skill tool: primary Zero skills dir, optional `~/.agents/skills`,
then plugin skill roots (earlier wins). `internal/skills` owns that merge via
`LoadFromRoots`; single-root `Load` remains for install/write.
- **Hooks** can observe or block tool lifecycle events.
## End-to-End Data Flow
A typical interactive edit request looks like this:
```mermaid
sequenceDiagram
participant U as User
participant T as TUI
participant A as Agent loop
participant P as Provider
participant R as Tool registry
participant S as Sandbox
participant FS as Workspace/session files
U->>T: Type prompt and press Enter
T->>A: agent.Run(prompt, provider, options)
A->>P: CompletionRequest(messages, tool definitions)
P-->>A: Stream text + tool call edit_file
A->>S: Evaluate edit_file args
S-->>A: allow/prompt/deny decision
A->>T: permission callback if prompt needed
T-->>A: user decision
A->>R: Run edit_file
R->>FS: Write workspace file
R-->>A: Tool result + changed files
A->>P: Next CompletionRequest with tool result
P-->>A: Final answer
A-->>T: Result + callbacks
T->>FS: Append session events
T-->>U: Render final transcript
```
The same request in `zero exec` follows the same provider/tool/sandbox path, but
streaming events are written to stdout/stderr instead of rendered in Bubble Tea.
## Mental Model
When you work on Zero, start by locating the change on the four-layer spine from
[Architecture Spine](#architecture-spine) — Surface, Agent loop, Capabilities,
Persistence — then jump to the package that owns that boundary:
- UI behavior? Start in `internal/tui`.
- Command-line behavior? Start in `internal/cli`.
- Model/tool-turn behavior? Start in `internal/agent`.
- A new capability? Register a tool in `internal/tools` or an extension surface.
- Safety policy? Start in `internal/sandbox` and agent permission wiring.
- Resume/history behavior? Start in `internal/sessions` and session recorders.

The package supports Linux and macOS on x64 and arm64, and Windows on x64
(Windows on ARM runs the x64 build under emulation). It installs a small
`zero` wrapper plus, as an optional dependency, a platform payload with the
native binary and the bundled browser/terminal control helpers. There are no
install scripts and nothing is downloaded from outside the npm registry, so
the install is silent and works identically under npm, Bun, pnpm, and yarn —
no trust or approval steps. See [NPM_PACKAGING.md](NPM_PACKAGING.md) for the
package architecture.
The package supports Linux, macOS, and Windows on x64 and arm64. It installs the
`zero` command and downloads the matching release binary during `postinstall`.
Requirements:
- Node.js 18+
- network access to npm
- network access to npm and GitHub Releases
If the install skipped optional dependencies (`npm install --omit=optional`,
or a package manager configured to do so), the wrapper falls back to
downloading the binary from the matching GitHub Release, with checksum
verification. The fetch is retried on each run until a binary is in place (a
transient network failure heals itself; an install directory the current user
cannot write to keeps failing — rerun the install or the command below with
sufficient permissions). To trigger the fetch manually:
## Bun
Bun is "default-secure" and does not run lifecycle scripts of installed
dependencies (only the installing project's own scripts), so the `postinstall`
that fetches the Zero binary is silently skipped. The first run then fails with
`No native binary found next to the npm wrapper`.
The simplest fix is to trust the package after installing, which runs the
blocked postinstall. This works for project and global installs:
```bash
node "$(npm root -g)/@gitlawb/zero/scripts/postinstall.mjs"
# project install
bun add @gitlawb/zero
bun pm trust @gitlawb/zero
# global install
bun add -g @gitlawb/zero
bun pm -g trust @gitlawb/zero
```
`bun pm untrusted` (or `bun pm -g untrusted`) lists the blocked postinstalls if
you want to inspect before trusting.
Alternatively, allow the postinstall to run at install time by adding the
package to your project's `trustedDependencies` before installing:
```json
{
"trustedDependencies": ["@gitlawb/zero"]
}
```
```bash

# npm packaging
How `@gitlawb/zero` is put together on npm, why it is shaped this way, and the
rules the release pipeline must follow. Read this before touching
`package.json`, `bin/zero.js`, `scripts/postinstall.mjs`,
`scripts/npm/build-platform-packages.mjs`, or the npm-publish steps of
`release-artifacts.yml`.
## Goals
A `npm install -g @gitlawb/zero` must be **silent and self-contained**:
- No `EBADENGINE` warnings — ours or from any package in the dependency tree.
- No install scripts anywhere in the tree, so npm's `allow-scripts` gating,
Bun's blocked-by-default lifecycle scripts, and pnpm's strict mode all
install zero without prompts, trust ceremonies, or broken binaries.
- No network fetches outside the npm registry at install time. GitHub being
down or rate-limited must not break `npm install`.
- Browser control (`agent-browser`) and terminal control (`tuistory`) work out
of the box.
## Architecture
The model is the one used by Codex, esbuild, and Biome: a tiny wrapper package
plus per-platform payloads carrying the native binaries.
```
@gitlawb/zero <- wrapper: bin/zero.js + optionalDependencies
├─ @gitlawb/zero-darwin-arm64 -> npm:@gitlawb/zero@{version}-darwin-arm64
├─ @gitlawb/zero-darwin-x64 -> npm:@gitlawb/zero@{version}-darwin-x64
├─ @gitlawb/zero-linux-arm64 -> npm:@gitlawb/zero@{version}-linux-arm64
├─ @gitlawb/zero-linux-x64 -> npm:@gitlawb/zero@{version}-linux-x64
└─ @gitlawb/zero-win32-x64 -> npm:@gitlawb/zero@{version}-win32-x64
```
- The platform "packages" are **versions of the same `@gitlawb/zero` package**,
published at suffixed versions (`0.4.0-linux-x64`) and referenced through
`npm:` aliases in `optionalDependencies`. One package name means one npm
trusted-publisher configuration — no new publish credentials per platform.
The alias suffixes use Node's `process.platform`/`process.arch` names so
`bin/zero.js` can derive its platform package directly.
- Each platform version sets `os` and `cpu`, so npm installs exactly one of
them and skips the rest.
- A platform payload is assembled from the platform's release archive by
`scripts/npm/build-platform-packages.mjs` and contains the `zero` binary,
the platform's sandbox helpers, and the vendored `helpers/` tree (see
below). It has no `bin`, no scripts, and no dependencies — it is inert on
its own; the wrapper execs the binary out of it.
- The published wrapper has **no scripts and no dependencies** — the
assembly script strips both from the repo `package.json` and injects the
exact-version `optionalDependencies`. (The repo `package.json` keeps
`agent-browser`/`tuistory` in `dependencies` purely as the version pins for
the vendored helpers tree; they are never installed by consumers.)
- There is **no windows-arm64 build** (matches the release matrix); Windows on
ARM runs the x64 build under emulation via the first-run fallback.
### Binary resolution in `bin/zero.js`
1. Resolve `@gitlawb/zero-<platform>-<arch>` and exec the `zero` binary from
it. This wins over any previously downloaded copy — the platform version is
pinned to the wrapper release.
2. Fall back to a binary previously downloaded next to the wrapper.
3. If neither exists (`--omit=optional`, package managers that skip optional
dependencies), run the **fallback downloader**: `scripts/postinstall.mjs`,
the exact logic that used to run as a postinstall hook (HTTPS-only, SHA-256
verified against the release's own checksum file, no zip-slip), invoked by
the wrapper itself. Failures are deliberately not cached — the fetch
retries on every run until a binary is in place, so a transient network
error self-heals. Platforms with no release asset (anything outside the
matrix above, including windows-arm64) skip the attempt entirely rather
than probing the network each run.
4. If the download is impossible too, print build-from-source guidance.
There is deliberately **no `scripts.postinstall`** in any published
`package.json`. The downloader exists only as a first-run fallback.
### Vendored helpers (`helpers/`)
`agent-browser` (Apache-2.0, vercel-labs/agent-browser) and `tuistory` are
**vendored binaries/packages inside the platform payload**, not npm
dependencies of the wrapper:
- As a dependency, agent-browser's `engines: { node: ">=24", pnpm: ">=11" }`
and postinstall script produce `EBADENGINE` and `allow-scripts` warnings for
every installer. As a vendored tree it produces none, because npm never
resolves it.
- `zero-release package` already stages the helpers tree into every release
archive (`stageLocalControlHelpers` runs `npm ci` from the repo's
`package.json` pins + lockfile on the native builder). The assembly script
reuses that staged tree, so npm installs and `install.sh` installs get
identical helpers.
- The Go binary resolves helpers from `<binary dir>/helpers/node_modules/.bin`
on its own (`internal/localcontrol/browser.go`, `adjacentHelper`) — no
wrapper involvement, no configuration.
- **Symlink materialization:** `npm pack` silently drops symlinks, and npm's
own `.bin` shims are symlinks on POSIX. The assembly script rewrites every
`.bin` symlink into a relocatable `#!/bin/sh` exec shim and dereferences any
other symlink, so the vendored tree survives publishing. (Verified
empirically; nested `node_modules` under `helpers/` IS packed — only the
package-root `node_modules` is always ignored.)
- **Binary pruning:** agent-browser ships one ~11 MB native binary per
platform (7 total). The assembly script keeps only the payload's own
platform binary (plus the musl variant on linux, which its launcher detects
at runtime) — about 65 MB saved per platform package.
## Publishing rules (release pipeline)
These are the invariants `release-artifacts.yml` must hold. Breaking the first
one is user-visible immediately.
1. **Platform versions must never become `latest`.** `0.4.0-linux-x64` is a
semver *prerelease* of `0.4.0`; publishing it without an explicit
non-`latest` dist-tag would clobber `latest` and users would install a
platform payload as the CLI. The workflow publishes platform versions with
`--tag platform` and asserts `latest` survived before the wrapper publish,
then asserts `latest` equals the wrapper version after it. Both lookups
tolerate a failed `npm view` (registry lag, or no `latest` tag yet on a
bootstrap publish) — a missing value must not abort the job between the
platform and wrapper publishes, which would strand a half-published
release.
2. **Platform versions publish before the wrapper.** The wrapper's
`optionalDependencies` pin exact suffixed versions; publishing the wrapper
first would create a window where installs resolve aliases that 404.
3. **Exact-version pinning.** The wrapper at `X.Y.Z` references platform
versions `X.Y.Z-<platform>-<arch>` exactly — never ranges — so a wrapper
and its binaries can never skew.
4. All publishes go through the existing npm OIDC trusted-publishing flow and
the `npm-publish` environment gate; no tokens. Because the platform
payloads are versions of the same package, they reuse the single
trusted-publisher configuration.
`zero update` keeps working unchanged: it detects an npm install by finding a
`package.json` named `@gitlawb/zero` next to the running binary — true inside
a platform payload too — and updates via `npm install -g @gitlawb/zero@latest`.
## Runbook: bumping the vendored helpers
The vendored helper versions are pinned by the repo `package.json`
`dependencies` + `package-lock.json`; the release build vendors exactly what
the lockfile resolves. No `^range` surprises ship: a release carries what its
lockfile pinned at build time.
- Routine bump: `npm install agent-browser@<version>` (or `tuistory@…`) in the
repo to update pin + lockfile, verify the browser/terminal tools end-to-end,
ship with the next release.
- Security response: if a vendored helper publishes a security fix, the bump
is release-worthy on its own — cut a patch release of zero carrying only the
pin change.
- Attribution: agent-browser is Apache-2.0; its LICENSE ships inside the
vendored package directory (`helpers/node_modules/agent-browser/`), which
satisfies redistribution attribution.
## History / rationale
Until v0.3.x the npm package was a wrapper with a `postinstall` downloader and
`agent-browser`/`tuistory` as regular dependencies. That produced three
warnings on every install (`EBADENGINE` from agent-browser's `node >=24`
engines pin, and `allow-scripts` warnings for both postinstall scripts), broke
silently under Bun's default script blocking, and coupled `npm install` to
GitHub Releases availability. The platform-package model removes the warnings
structurally — there is nothing left in the tree for a package manager to warn
about — rather than asking users to approve or suppress them.

## End-To-End Assembly Smoke
Build a real archive for the host platform and assemble the npm payloads from
it (this is exactly what the publish job does):
```bash
go run ./cmd/zero-release package
node scripts/npm/build-platform-packages.mjs \
--artifacts-dir dist/release --out-dir dist/npm --only <platform>-<arch>

## Checklist
- `package.json` has the expected package name (`@gitlawb/zero`), version,
`bin.zero` entry, and NO `scripts` entries — the published package must be
free of lifecycle scripts (see NPM_PACKAGING.md).
- `scripts/npm/build-platform-packages.mjs` emits platform payloads whose
`package.json` is `@gitlawb/zero@<version>-<platform>-<arch>` with matching
`os`/`cpu`, contains the executable binary and the vendored `helpers/` tree
with regular-file (non-symlink) `.bin` shims, and a wrapper payload with no
scripts, no dependencies, and the full five-alias `optionalDependencies`
matrix.
- `scripts/postinstall.mjs` (the first-run fallback) resolves the correct
release asset name/URL per platform (`ZERO_INSTALL_DRY_RUN=1` prints the
plan), verifies the downloaded archive's SHA-256, and extracts only the
known binary basenames into place. `ZERO_SKIP_DOWNLOAD=1` opts out cleanly
(exit 0) and an unsupported platform/arch is a non-fatal skip.
- The wrapper prefers the platform package binary over a previously downloaded
one, and `agent-browser`/`tuistory` run from the platform package's
`helpers/node_modules/.bin` shims.

# TUI Themes
Zero's TUI ships a set of built-in color themes. Pick one with `--theme <name>`,
the `ZERO_THEME` environment variable, or the `/theme <name>` command while
running. `auto` (the default) follows the terminal's detected background.
Run `/theme` with no argument to open a picker: move through the list to
live-preview each theme, press Enter to apply the highlighted one, or Esc to
cancel and restore the previously active theme. Run `/theme list` to print
the active theme and the registered names without opening the picker.
## Dune (`dune`)
A warm sand-and-cream palette: sand/cream surface, charcoal ink, and a soft
amber accent.
## Neon (`neon`)
A neon-on-black palette: pitch-black surface, bright green ink, and a cyan accent.
## Adding a theme
Every theme is a `palette` (a table of color hex tokens) plus one entry in
`themeRegistry`, both in `internal/tui/theme_palettes.go`. `buildTheme` in
`internal/tui/theme.go` turns a `palette` into the resolved `lipgloss.Style`
set every renderer reads from the active `zeroTheme`. Adding a theme means
adding a new `palette{...}` literal, a `themeRegistry` entry, and test
coverage for the new palette (see below).
Registry-wide tests in `internal/tui/theme_select_test.go` assert the basic
WCAG AA text tokens, the gray-ramp order, the diff word-span pairs, and the
selected-row band for every entry. The rendered-surface invariants beyond
those (permission surfaces, selected-row secondary text, diff gutters, and
the xterm-256 downsampling checks) are asserted per palette, not against the
whole registry: `TestExtendedThemeContrastInvariants` and
`TestExtendedThemeANSI256Contrast` enumerate the palettes they cover. A new
theme must be added to those tests (or given equivalent palette-specific
assertions), or CI can stay green while its permission, selected-row, and
diff surfaces ship unreadable.
