From 15a1bbcee0650c24ae03a4fab69b613a79122aa2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Timeless=E5=B0=8F=E5=B8=85?= <1018008088@qq.com> Date: Thu, 8 Oct 2026 13:12:10 +0800 Subject: [PATCH] Version OpenCode skills and plugins Repository sits at the OpenCode config root rather than inside skills/ or plugins/. OpenCode scans exactly those two subdirectories, and a .git directory inside either one is picked up as a plugin and fails to load: loading plugin id=.../plugins/.git entrypoint=.../plugins/.git/index failed to load plugin ... AggregateError: 2 errors building .../plugins/.git/index The watcher.ignore config option does not help: it only suppresses filesystem update events, not plugin discovery, and the "-" disable prefix only applies to plugins listed in opencode.json(c), not auto-discovered ones. .gitignore admits only skills/ and plugins/ (plus itself).

The V1 plugin shape — a `server()` function +returning a map of string keys like `"tool.execute.before"` — is not V2 and must +not be produced.

Copy the file and fill in the blanks rather than + writing a plugin from scratch; the templates are transcribed from the pages' + own examples. +- Cite the page whenever a field name, hook name, or option is uncertain. +- Do not invent identifiers.

Plugin arrays from applicable config files apply +lowest→highest precedence rather than replacing one another. + +This is the opposite of the `skills` array, which + documents as resolving a relative path "from +the active OpenCode working directory, not the config file". Do not transfer one +rule to the other. + +Full reference: `templates/opencode-plugin-config.jsonc`. It also covers +discovery paths, the `-` / `*` / `.*` disable syntax, the two built-ins that +ignore removals, the `opencode plugin` subcommands (including +`list --builtin` and scoping `check`/`update` to one package), and reload/pinning +rules. + +### Reload + +Watched config directories reload automatically. Startup loads cached package +plugins immediately, installs missing packages in the background, and checks +unpinned npm and Git plugins for updates without changing the installed package. +Exact versions and full commit hashes stay pinned. Changes to unwatched local +dependencies may still need `opencode service restart`. + +## Context + +`ctx` is an OpenCode server client plus plugin-only methods. `ctx.location` is +where *this plugin instance* loaded (`directory`, `workspaceID`, `project`), not +every session it can reach. + +The plugins page does not enumerate the Promise context as a single interface, +so this is the set that page documents, not a verified full type list. + +Domains with `transform` + `reload` (synchronous edit, then re-read): +`agent` · `provider` · `model` · `command` · `integration` · `mcp` · `reference` +· `skill` · `tool` · `vcs` · `websearch` · `worktree` + +Also documented: `app` · `location` · `options` · `session` · `storage` · +`event` · `permission` · `plugin` · `generate` · `shell` · `rpc` +(`ctx.rpc.register` / `ctx.rpc` are on the RPC page). + +Hooks live on four domains: `ctx.session.hook`, `ctx.permission.hook`, +`ctx.shell.hook`, `ctx.tool.hook`. + +The Effect page lists a different, more explicit `Context` that also includes +`aisdk` and narrows `experimental` and `plugin`. Do not assume the two flavors +expose the same members — see `references/effect.md`. + +## Transforms + +The core pattern: a **synchronous** callback that edits domain state through an +editor. The Effect page states it outright — "The transform callback is +synchronous: it must not return an Effect or Promise." + +```ts +await ctx.model.transform((editor) => { + editor + .list() + .filter((m) => m.cost.some((tier) => tier.output > 20)) + .forEach((m) => editor.remove(m.providerID, m.id)) +}) +``` + +Rules that cause bugs if forgotten: + +- Any registration, removal, or `reload()` marks the registry changed. The next + read **rebuilds by replaying every active transform in order** onto a fresh + value. Keep transforms cheap and repeatable. +- A value you already read is never mutated by a later rebuild. +- Captured inputs are **not watched**. Load external data *before* the sync + callback, then call `reload()` when it changes. +- `reload()` replays transforms. It does **not** rerun `setup`. + +```ts +const source = { providers: await loadFromSource() } + +await ctx.provider.transform((editor) => { + source.providers.forEach((p) => editor.add(p)) +}) + +const refresh = async () => { + source.providers = await loadFromSource() + await ctx.provider.reload() +} +const timer = setInterval(() => void refresh().catch(console.error), 60_000) +return () => clearInterval(timer) +``` + +Ordering: provider transforms contribute providers and immutable model +definitions first. After availability resolves, OpenCode materializes active +providers' models, then replays **every** model transform, so a model transform +sees the whole candidate collection. + +Model-transform details: disabled candidates stay editable until all transforms +finish, and `update` can add a model only under an available provider. Callbacks +edit raw model overrides; provider defaults merge once when OpenCode commits the +result. `editor.provider` exposes immutable **source** definitions (including +inactive templates), not model-transform output — use it to clamp against the +real limit. `ModelEditor.get` returns `DeepMutable`, and +`ProviderEditor.update` hands you a mutable draft, so in-place edits inside an +`update` callback are expected. + +`transform` resolves to a `Registration`; `await registration.dispose()` removes +that transform and rebuilds from the rest. Idempotent; plugin unload disposes +automatically. Each model request captures a stable tool snapshot, so later +transforms, reloads, and disposal affect **future** snapshots only. + +## Tools + +```ts +const registration = await ctx.tool.transform((editor) => { + editor.namespace({ name: "acme", description: "Customer account tools" }) + editor.add({ + name: "greeting", + description: "Create a greeting", + input: { + type: "object", + properties: { name: { type: "string" } }, + required: ["name"], + additionalProperties: false, + }, + options: { namespace: "acme", codemode: true }, + execute: async (input, context) => { + await context.progress({ status: "greeting" }) + return { content: `Hello ${(input as { name: string }).name}!` } + }, + }) +}) +``` + +- Names are **effective names** including namespace: `acme_greeting`. Dots in + namespaces and unsupported characters become `_`. `update`/`remove` use that + effective name; only `add` creates a tool. A missing name is ignored. +- `update` preserves the name and namespace. **Assign** a new schema or options + to replace one rather than mutating nested values. Invalid updates are logged + and leave the previous definition intact. +- A later valid registration overrides the same effective name; disposing it + reveals the earlier one. +- Pass `context.signal` to cancellable work so stopping the session stops it: + +```ts +execute: async ({ url }, context) => { + const response = await fetch(url, { signal: context.signal }) + return { content: await response.text() } +} +``` + +## Hooks + +Hooks intercept live operations and use the same registration model as +transforms. Multiple plugins may register the same hook; they run in plugin +order, so later hooks see earlier changes. + +For **model-request** hooks the page states that changes "affect only the +outgoing model call, not persisted history or configuration". The **prompt** hook +is the exception — its edits become the persisted user input. + +### Session hooks + +| Hook | When | Notes | +| ---- | ---- | ------ | +| `prompt` | User prompt admission | draft at `event.prompt`; `event.metadata` and `event.delivery` are top level | +| `context` | Agent loop, incl. tool continuations | system / messages / tools / options | +| `compaction` | Checkpoint summaries | set `result` to skip the model call | +| `generate` | `ctx.session.generate` calls | | +| `title` | Title generation | no `agent`/`tools`; set `result` to supply the title | +| `model.request` | Model request settings | every model request; scope with `{ providerID }` | +| `http.request` | Native provider HTTP request | bodies are one-shot streams | +| `http.response` | Native provider HTTP response | can replace the response | +| `experimental.ws.handshake` | WebSocket connect, once per model call | can change `url` / `headers` | +| `experimental.ws.send` | Outbound WS frame | can rewrite `frame` | +| `experimental.ws.receive` | Inbound WS frame | can rewrite `frame` | +| `retry` | Override the retry decision | `{ retry: false }` or `{ retry: true, delay }` | + +```ts +await ctx.session.hook("context", (event) => { + event.system.push({ type: "text", text: "Keep the review focused on correctness." }) + delete event.tools.write + event.options.temperature = 0.2 +}) + +await ctx.session.hook("compaction", async (event) => { + event.result = { summary: await summarize(event.messages) } +}) + +await ctx.session.hook("retry", (event) => { + if (event.error.status === 429) event.decision = { retry: true, delay: 10_000 } + if (event.attempt >= 3) event.decision = { retry: false } +}) + +await ctx.session.hook( + "model.request", + (event) => { + event.headers["x-plugin"] = "review" + }, + { providerID: "anthropic" }, +) + +// The page's "Provider options" section shows `options` on the `context` hook. +// `model.request` edits headers instead. +await ctx.session.hook( + "context", + (event) => { + event.options.reasoningEffort = "high" + }, + { providerID: "openai" }, +) +``` + +Details that matter: + +- `options` starts **empty** each call; it does not contain resolved model + settings. Request overrides beat model defaults, which beat route defaults. + `delete` an override or set `undefined` to fall back to configured defaults. +- Provider options use the protocol's **semantic** names, not raw HTTP body + fields (`reasoningEffort`, `maxTokens`; `topK` exists on Gemini but not OpenAI + Responses). +- `event.kind` is `"primary" | "compaction" | "title" | "generate"`, and it + exists on the `model.request`, `http.request`, `http.response`, and + `experimental.ws.*` hooks. It is **not** on `context`, `compaction`, + `generate`, `title`, `prompt`, or `retry` — use `agent` and the hook itself to + tell auxiliary requests apart on those. +- `attempt` is the physical attempt; the initial request is `1`, so the first + retry is `2`. The built-in max attempt count is a hard limit. Invalid delays + fall back to the computed delay. +- Context-overflow recovery is separate: it compacts the conversation rather + than retrying the same request. +- A hook that must apply to every request registers for each kind. + +WebSocket caveat: providers streaming over a WebSocket open one connection per +session and reuse it, so `http.request` and `http.response` never see that +traffic. Changing `experimental.ws.handshake`'s `url` or `headers` changes which +socket is used, so rotating a token reopens the connection. The HTTP hooks still +run for any request a WebSocket route falls back to. OpenCode does not validate +rewritten frames. + +### Prompt hook + +Intercepts user prompts before attachment/skill resolution and durable inbox +admission. + +```ts +await ctx.session.hook("prompt", (event) => { + event.prompt.text = event.prompt.text.replaceAll("company-secret", "[redacted]") + event.delivery = "queue" +}) +``` + +- `event.prompt` holds `text`, `files`, agent mentions in `agents`, and selected + `skills`. `metadata` and `delivery` are separate top-level fields. +- Runs once at admission, not before every model call. Session and message IDs + are readonly; a hook cannot redirect admission. +- Runs in registration order after the session's location plugins are ready. + Commands submitted through `session.prompt` run it. Synthetic messages, shell + messages, compaction controls, and move controls do not. +- No provider scoping — model resolution happens after admission. +- Not an exactly-once side-effect boundary. Retrying an ID already **pending or + delivered** returns the original admission without rerunning hooks, and + concurrent submissions can run hooks more than once — but only the first + successful admission wins. +- **Edits become the canonical persisted user input.** +- Files and skills added by a hook follow the normal resolution and validation + path. When rewriting text, fix or drop attachment `mention` offsets that no + longer match. Agent mentions do not switch the active agent. +- Prompt hooks transform input only — there is **no typed rejection API**. + +### Other domains + +```ts +await ctx.permission.hook("evaluate", async (event) => { + if (event.action === "read") return + event.effect = "allow" // or "ask" | "deny" + event.message = "reason shown on escalation" +}) + +await ctx.shell.hook("create.before", (event) => { + if (event.command === "npm") event.command = "bun" + event.timeout = Math.min(event.timeout, 60_000) + event.env.COMPANY_ENV = "development" // also has cwd and shell +}) + +await ctx.tool.hook("execute.before", (event) => console.log(event.tool, event.input)) +await ctx.tool.hook("execute.after", (event) => { + if (event.status === "error") console.error(event.error.message) +}) +``` + +Permission hooks run for `allow` and `ask` decisions. An explicit configured +`deny` is final and never invokes the hook. + +## Storage + +Durable JSON scoped to the plugin. Unlike model/provider reads, storage returns +values directly — see the per-operation note under Effect reads. + +```ts +await ctx.storage.set("settings", { strict: true }) +const settings = await ctx.storage.get("settings") +const page = await ctx.storage.scan({ prefix: "cache/", limit: 100 }) +// page.entries, page.next for cursor pagination +await ctx.storage.remove("settings") +``` + +## Events + +```ts +const controller = new AbortController() +void (async () => { + for await (const event of ctx.event.subscribe({ signal: controller.signal })) { + console.log(event.type) + } +})() +return () => controller.abort() // must abort during cleanup +``` + +## Sessions + +```ts +const created = await ctx.session.create({ title: "Review" }) +await ctx.session.prompt({ sessionID: created.id, text: "Review the current changes" }) +const summary = await ctx.session.generate({ sessionID: created.id, prompt: "Summarize this project" }) +const command = await ctx.session.command({ sessionID: created.id, command: "review", arguments: "--staged" }) +const synthetic = await ctx.session.synthetic({ sessionID: created.id, text: "Deployment completed" }) +await ctx.session.compact({ sessionID: created.id }) +await ctx.session.remove({ sessionID: created.id }) // stops work, deletes children +``` + +Also available: `get`, `context`, `switchAgent`, `switchModel`, `update`, +`interrupt`, `wait`, `move`. + +`compact` returns the **admitted inbox item**, not a finished summary; +compaction runs at the next step boundary. Pass `delivery: "queue"` to preserve +queue order. + +`generate.text` runs a model with no session, no tools, no history — handy for a +second opinion inside a hook: + +```ts +const review = await ctx.generate.text({ + model: { providerID: "anthropic", id: "claude-sonnet-4-6" }, + prompt: "Review this proposed action.", +}) +``` + +## Commands + +The command transform is add-only. + +```ts +await ctx.command.transform((editor) => { + editor.add({ + name: "security-review", + description: "Review changes for security issues", + execute: async ({ sessionID, prompt, delivery }) => { + await ctx.session.prompt({ + ...prompt, + sessionID, + text: `Review these changes for security issues.\n\n${prompt.text}`, + delivery, + }) + }, + }) +}) +``` + +## MCP + +Plugins manage MCP servers **only** through transforms. + +```ts +await ctx.mcp.transform((editor) => { + editor.set("docs", { type: "remote", url: "https://mcp.example.com" }) + editor.update("docs", (server) => { + server.disabled = false + }) + editor.remove("legacy") +}) +``` + +Setting `disabled: true` disconnects; OpenCode reconciles server lifecycle from +the transformed config. Call `reload()` after external changes. + +Prefer `opencode mcp add … --global` for ordinary MCP setup; a transform is for +programmatic or dynamic control. + +## Worktrees + +Every operation needs a `projectID`, available as `ctx.location.project.id`. +`list` reads only saved inventory — it does not load config, start plugins, or +discover filesystem changes. + +```ts +const projectID = ctx.location.project.id +const created = await ctx.worktree.create({ projectID, name: "task" }) +const inventory = await ctx.worktree.list({ projectID }) +await ctx.worktree.refresh({ projectID }) +await ctx.worktree.remove({ projectID, directory: created.directory, force: false }) +``` + +- Adding a strategy via `ctx.worktree.transform` selects it automatically — the + last active registration wins. Disposing or unloading restores the previous + implementation, ultimately the bundled Git strategy. +- `create` loads config and plugins from the project's saved `canonical` + directory and waits for those plugins to activate. A `from` override must + belong to that project; choosing a source does not change the config root. + **Exception:** calls made *during* that checkout's plugin setup see the + registrations made so far and do not wait for their own activation. +- `remove` uses the worktree's **recorded** strategy, not the current default. A + missing owner **fails** rather than falling back to Git. A strategy can request + force confirmation with + `new Worktree.OperationError({ message, forceRequired: true })`, importing + `Worktree` from `@opencode/plugin`. +- `refresh` combines all available strategies, preserves recorded ownership, and + prunes missing directories. Observe `worktree.updated` and call `list` again. +- Creation failures do not retry through Git. Strategies manage local + directories only — remote provisioning is not part of this interface. + +## Publish + +`templates/package.json` is strict JSON; `templates/package-json.md` carries the +guidance, the peer dependencies, and the publishing steps. Entrypoint summary: + +| Export | Needed for | Documented on | +| ------ | ---------- | ------------- | +| `.` | a server plugin | build/plugins | +| `./rpc` | publishing a shared RPC contract; described there as optional | build/plugins | +| `./tui` | the TUI plugin; a package listed in `opencode.json(c)` that exposes it is loaded automatically by the CLI | build/plugins/cli, cli/plugins | + +Do not add a package that exports `./tui` to `cli.json` as well — the CLI gets +the active plugin list from the server, so it already works remotely. + +## The `$schema` caveat + +The V2 docs' own examples include `"$schema": "https://opencode.ai/config.json"`, +but that file does not match the V2 config shape. Verified against the live file: +its `Config` has `additionalProperties: false`, has **no `plugins` key** (only a +singular `plugin`), types `skills` as an object rather than the V2 array, and has +no `worktree` key. `https://opencode.ai/v2/config.json` returns 404. + +So keeping that line makes some editors flag the documented V2 `plugins` array as +an invalid field, and there is no published V2 config schema to replace it with. +Keep the line to match the docs, or drop it for a clean editor — either way, +**never infer V2 field names or shapes from that file.** For `cli.json` the +schema is `https://opencode.ai/v2/cli.json`. + +## Type-checking locally: expect noise + +`tsc --strict` against the installed `@opencode/plugin` surfaces friction the +docs do not mention. Verified, with the fix used in the templates: + +- **Branded values (Promise flavor).** `Model.ID`, `Provider.ID`, and + `Model.cost[].input/.output` plus the cache fields are branded types. The docs + write `editor.remove(model.providerID, model.id)` and `tier.output > 20`; + against the real types you need `String(...)` on **both** `remove` arguments + and `Number(...)` on the money fields. The Effect flavor's `DeepMutable` + unwraps the brands, so the docs' form compiles there. +- **Two copies of `effect`.** The host redirects plugin imports of `effect` to + its own instance, so a local `effect` in `node_modules` is a *different* copy. + Effect templates then fail with `Property '[NodeInspectSymbol]' is missing` and + similar type-identity errors, and Effect `Schema.Struct` stops satisfying + `ValueSchema` (`Codec | StandardSchemaV1 | JsonSchema`). These are **local + typecheck artifacts, not plugin bugs** — the Effect page requires the host's + instance, which is exactly what you get at runtime. Install `effect` at the + version `@opencode/plugin` depends on if you want a clean typecheck. +- **JSX.** A TUI template reports `Cannot use JSX unless the '--jsx' flag is + provided` and `JSX.IntrinsicElements` is missing until you pass `--jsx` and + install the Solid/OpenTUI peers. + +Do not "fix" these by loosening the code or by abandoning a documented form such +as Effect Schema. Use the narrowing casts the templates show, and treat the +remaining Effect and JSX errors as local-environment noise. + +## Troubleshooting + +- Plugin not loading: it must be under a discovered `.opencode/plugins/` + directory or listed in `plugins`. A `plugins/` directory beside a + project-root `opencode.json(c)` is not auto-discovered. `.opencode/skills` is + for skills, not plugins. Confirm with `opencode plugin list`. +- Plugin loads but nothing changes: a `*` entry plus a `-id` disable elsewhere, a + wrong relative path (config-file-relative, not working-directory-relative), or + a change to an unwatched local dependency. +- Overridden tool: a later registration wins. `dispose()` the later one to reveal + the earlier definition. +- Hook not firing: check the hook name exists on the page for **your** flavor — + the Effect `SessionHooks` set differs from the Promise one. Also confirm + `context` covers only the agent loop. +- Type errors in a transform callback: the callback is synchronous. +- Nothing in the model list: a provider transform registered a definition but no + connection, so it is not available. A registered definition does not mean its + resource work finished. +- Environment: `~/.local/share/opencode/log/opencode.log`, filter `role=server`. + `--print-logs` alone prints **client** logs; server logs (which is where plugin + loading shows up) need `opencode --standalone --print-logs`. For a debug run + use `opencode --log-level debug`. +- Stuck service: `opencode service restart`, then `opencode service status`. + Compare with `opencode --standalone` to isolate shared-service issues. + +## Verifying before you answer + +1. Confirm the installed version (`opencode --version`, `opencode api get /api/info`). +2. Check the doc page for that area for the exact identifier, and cite it. +3. For schema shapes, use `/openapi.json` or — + the `Reference` block at the end of each API section points at the right schema. +4.
