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). Personal config
(opencode.jsonc, cli.json, service.json) and node_modules stay local.

# OpenCode V2 Plugins
|
||||||
|
|
||||||
|
OpenCode plugins extend the service and the terminal. Pick the flavor first,
|
||||||
|
copy the matching file from `templates/`, then read the matching reference.
|
||||||
|
|
||||||
|
**V2 only.** V1 is out of scope: V1 plugins, `server()`-returned hook maps, the
|
||||||
|
`opencode.ai/docs/` site, and the V1→V2 migration material are all out of scope
|
||||||
|
here. See "Version scope" below.
|
||||||
|
|
||||||

|
The running server serves an OpenAPI document at `/openapi.json`
|
||||||
|
(`opencode api get /openapi.json`). It self-describes as an experimental
|
||||||
|
HttpApi surface for selected instance routes, so it covers the HTTP contract,
|
||||||
|
not the plugin API — transforms, hooks, and `Plugin.define` are not routes. Use
|
||||||
|
the `/api` reference page for schemas.
|
||||||
|
|
||||||
|
## Check the installed version first
|
||||||
|
|
||||||
|
Plugin APIs **and package names** change between releases, so confirm what the
|
||||||
|
user actually has before writing anything.
|
||||||
|
|
||||||
|
```sh
|
||||||
|
opencode --version # e.g. v2.0.24
|
||||||
|
opencode api get /api/info # version + pid + urls + capabilities
|
||||||
|
opencode plugin list # what is loaded right now
|
||||||
|
opencode service status # the background service URL
|
||||||
|
```
|
||||||
|
|
||||||
|
### Install the package that matches your release
|
||||||
|
|
||||||
|
The docs' import specifiers are correct. The package is **not bundled with the
|
||||||
|
CLI** — you install it yourself, at the version matching your OpenCode release:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
opencode --version # e.g. v2.0.24
|
||||||
|
cd ~/.config/opencode
|
||||||
|
npm install @opencode/plugin@$(opencode --version | sed 's/^v//')
|
||||||
|
opencode service restart # required: the running
|
||||||
|
# service caches resolution
|
||||||
|
```
|
||||||
|
|
||||||
|
A missing package fails loudly per-plugin rather than breaking the whole
|
||||||
|
instance:
|
||||||
|
|
||||||
|
```
|
||||||
|
failed to load plugin … Cannot find package '@opencode/plugin' imported from
|
||||||
|
/home/you/.config/opencode/plugins/<name>/index.ts
|
||||||
|
```
|
||||||
|
|
||||||
|
A **stale `@opencode-ai/plugin`** (the V1-era package name) sitting in
|
||||||
|
`~/.config/opencode/node_modules` is a red herring. It is a leftover user-side
|
||||||
|
dependency; it does **not** reflect what the host provides. Do not read its
|
||||||
|
export list and conclude that `@opencode/plugin` "does not exist" — check npm
|
||||||
|
(`npm view @opencode/plugin version`) instead. The real `@opencode/plugin`
|
||||||
|
ships a `Plugin` namespace with `Plugin.define`, plus `Model`, `Provider`,
|
||||||
|
`Rpc`, `WebSearch`, `Vcs`, and `Worktree`, and its `./*` subpath resolves
|
||||||
|
`@opencode/plugin/rpc`.
|
||||||
|
|
||||||
|
TUI plugins also need the peers from that package (`solid-js`,
|
||||||
|
`@opentui/core`, `@opentui/solid`, `@opencode/theme`).
|
||||||
|
|
||||||
|
### Verify the default export
|
||||||
|
|
||||||
|
The host requires a **default export** carrying `id` and either `setup` or
|
||||||
|
`effect`. Without one:
|
||||||
|
|
||||||
|
```
|
||||||
|
failed to load plugin … Plugin must export a default definition with an id and
|
||||||
|
an effect or setup function.
|
||||||
|
```
|
||||||
|
|
||||||
|
If a plugin loads but does nothing, check the log at
|
||||||
|
`~/.local/share/opencode/log/opencode.log`, filtering on the plugin directory
|
||||||
|
name.
|
||||||
|
|
||||||
|
To confirm the runtime context on an unfamiliar machine, write a read-only probe
|
||||||
|
under `~/.config/opencode/plugins/` that dumps `Object.keys(ctx)` to a file from
|
||||||
|
`setup` — do not register hooks, transforms, or tools.
|
||||||
|
|
||||||
|
## Version scope
|
||||||
|
|
||||||
|
Answer for the V2 plugin API. 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. A V2 plugin uses `Plugin.define` with typed hooks.
|
||||||
|
|
||||||
|
Never cite <https://opencode.ai/docs/>. It documents V1. If a question only makes
|
||||||
|
sense for V1, say so rather than answering from memory.
|
||||||
|
|
||||||
|
## Follow the docs and the templates
|
||||||
|
|
||||||
|
- Start from `templates/`. 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. A plausible-sounding hook name that is not in the
|
||||||
|
docs silently never fires, and an invented config field can fail to parse.
|
||||||
|
- Do not "improve" on the documented shape. If you need behavior the docs do
|
||||||
|
not describe, say so and propose the closest supported approach.
|
||||||
|
- Prefer the page's own example over any type signature quoted here. Several
|
||||||
|
reference types in these docs are simplified and omit real parameters.
|
||||||
|
|
||||||
|
## Entrypoints
|
||||||
|
|
||||||
|
Four entrypoints. The RPC contract has a Promise and an Effect variant, so it
|
||||||
|
appears as two rows:
|
||||||
|
|
||||||
|
| Entrypoint | Import | Runs in | Reference | Template |
|
||||||
|
| ---------- | ------ | ------- | --------- | -------- |
|
||||||
|
| Server (Promise) | `@opencode/plugin` | background service | this file | `templates/promise-plugin.ts` |
|
||||||
|
| Server (Effect) | `@opencode/plugin/effect` | background service | `references/effect.md` | `templates/effect-plugin.ts` |
|
||||||
|
| RPC contract | `@opencode/plugin/rpc` | contract only, no code | `references/rpc.md` | `templates/rpc.ts` |
|
||||||
|
| RPC (Effect contract) | `@opencode/plugin/rpc` | contract only, no code | `references/rpc.md` | `templates/rpc-effect.ts` |
|
||||||
|
| TUI / CLI | `@opencode/plugin/tui` | terminal frontend | `references/cli.md` | `templates/tui-plugin.tsx` |
|
||||||
|
|
||||||
|
Supporting files: `templates/rpc-implementation.ts` (Promise registration),
|
||||||
|
`templates/rpc-implementation-effect.ts` (Effect registration),
|
||||||
|
`templates/opencode-plugin-config.jsonc` (config reference),
|
||||||
|
`templates/package.json` + `templates/package-json.md` (publishing).
|
||||||
|
|
||||||
|
Default to the Promise server flavor. Use Effect only when the project already
|
||||||
|
uses Effect. A TUI plugin is a separate export from a server plugin.
|
||||||
|
|
||||||
|
## Shape
|
||||||
|
|
||||||
|
```ts
|
||||||
|
import { Plugin } from "@opencode/plugin"
|
||||||
|
|
||||||
|
export default Plugin.define({
|
||||||
|
id: "example",
|
||||||
|
async setup(ctx) {
|
||||||
|
await ctx.storage.set("loaded", true)
|
||||||
|
},
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
`setup` runs at load and may return a cleanup function that runs at unload.
|
||||||
|
Pick an `id` that will not collide — the page does not give naming guidance.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
setup(ctx) {
|
||||||
|
const timer = setInterval(() => void refresh(), 60_000)
|
||||||
|
return () => clearInterval(timer)
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Options arrive on the untyped `ctx.options` — narrow before use:
|
||||||
|
`const strict = ctx.options.strict === true`.
|
||||||
|
|
||||||
|
## Loading
|
||||||
|
|
||||||
|
Plugins under a discovered `.opencode/plugins/` directory load automatically.
|
||||||
|
Packages and directories elsewhere must be listed in `plugins` in
|
||||||
|
`opencode.json(c)`:
|
||||||
|
|
||||||
|
```jsonc
|
||||||
|
{
|
||||||
|
"$schema": "https://opencode.ai/config.json",
|
||||||
|
"plugins": [
|
||||||
|
"opencode-acme-plugin",
|
||||||
|
"opencode-acme-plugin@1.2.0",
|
||||||
|
"@acme/opencode-plugin",
|
||||||
|
"./plugins/local",
|
||||||
|
"../shared/plugin.ts",
|
||||||
|
"/absolute/path/plugin.ts",
|
||||||
|
"file:///home/me/plugins/local",
|
||||||
|
{ "package": "./plugins/company", "options": { "strict": true } }
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Relative paths resolve from the config file containing the entry**, not from
|
||||||
|
the working directory. Plugin arrays from applicable config files apply
|
||||||
|
lowest→highest precedence rather than replacing one another.
|
||||||
|
|
||||||
|
This is the opposite of the `skills` array, which
|
||||||
|
<https://opencode.ai/v2/docs/skills> 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<Model.Info>`, 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 <https://opencode.ai/v2/docs/api> —
|
||||||
|
the `Reference` block at the end of each API section points at the right schema.
|
||||||
|
4. If a page is silent, or a claim cannot be traced to a page, say so and mark it
|
||||||
|
as inference. Do not guess a field name or present an inference as documented.
|
||||||
|
|
||||||
|
## Rules the pages state
|
||||||
|
|
||||||
|
- A `transform` callback is typed `(editor) => void` in both flavors.
|
||||||
|
- Tool `update` preserves name and namespace; assign new schemas or options
|
||||||
|
rather than mutating nested values.
|
||||||
|
- `reload()` replays transforms. It does not rerun `setup` (Promise) or the
|
||||||
|
plugin `effect` (Effect).
|
||||||
|
- Use the effective tool name including its namespace for `update`/`remove`.
|
||||||
|
- Tear down event subscriptions: `AbortController` in Promise, `forkScoped` in
|
||||||
|
Effect.
|
||||||
|
- Prefer a page's example over any simplified type signature quoted in a
|
||||||
|
reference — the docs' shared `Hooks<Spec, Failures>` type, for instance, omits
|
||||||
|
the provider-scoping argument their own examples pass.

# TUI / CLI Plugins
|
||||||
|
|
||||||
|
**Docs: <https://opencode.ai/v2/docs/build/plugins/cli/>** — fetch this page
|
||||||
|
before writing a TUI plugin. This file is a summary of it.
|
||||||
|
**Loading: <https://opencode.ai/v2/docs/cli/plugins>**
|
||||||
|
**Template: `../templates/tui-plugin.tsx`**
|
||||||
|
|
||||||
|
`@opencode/plugin/tui` extends the **terminal frontend** with commands, routes,
|
||||||
|
slots, Markdown renderers, notifications, and local state. A TUI plugin is a
|
||||||
|
separate export from a server plugin — one package can have both.
|
||||||
|
|
||||||
|
```ts title="src/tui.ts"
|
||||||
|
import { Plugin } from "@opencode/plugin/tui"
|
||||||
|
|
||||||
|
export default Plugin.define({
|
||||||
|
id: "acme.cli",
|
||||||
|
setup(context) {
|
||||||
|
context.ui.toast.show({ message: "CLI plugin loaded", variant: "success" })
|
||||||
|
},
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Import `@opencode/plugin/tui` directly. OpenCode resolves it at runtime, so a
|
||||||
|
local plugin needs no absolute path to an OpenCode checkout. `setup` may return
|
||||||
|
a cleanup function.
|
||||||
|
|
||||||
|
## Context
|
||||||
|
|
||||||
|
`setup` receives configuration, app metadata, the current location, the client,
|
||||||
|
cached data, theme tokens, the OpenTUI renderer, and the UI APIs.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
setup(context) {
|
||||||
|
const compact = context.options.compact === true
|
||||||
|
const location = context.location ?? context.data.location.default()
|
||||||
|
const version = context.app.version
|
||||||
|
const channel = context.app.channel
|
||||||
|
const client = context.client
|
||||||
|
const renderer = context.renderer
|
||||||
|
const theme = context.theme
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
`context.client` is the generated client and works against a remote server.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const response = await context.client.plugin.list({
|
||||||
|
location: context.location ?? context.data.location.default(),
|
||||||
|
})
|
||||||
|
const plugins = response.data
|
||||||
|
```
|
||||||
|
|
||||||
|
## Events
|
||||||
|
|
||||||
|
`data.on` handles one typed event, `data.listen` handles every server event.
|
||||||
|
Both return an unsubscribe function.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const stopPermission = context.data.on("permission.asked", (event) => {
|
||||||
|
context.ui.toast.show({ message: `Permission ${event.data.id}` })
|
||||||
|
})
|
||||||
|
const stopAll = context.data.listen(({ details }) => console.log(details.type))
|
||||||
|
|
||||||
|
return () => {
|
||||||
|
stopPermission()
|
||||||
|
stopAll()
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Cached data
|
||||||
|
|
||||||
|
Reads are served from local cached data; the page also exposes `sync` and
|
||||||
|
invalidation ("synchronization, and invalidation" for sessions, "refresh
|
||||||
|
controls" for location). Do not assume `invalidate` empties the cache or that a
|
||||||
|
`list()` immediately after it returns an empty array — the page does not say
|
||||||
|
that.
|
||||||
|
|
||||||
|
Most collections expose `list`, `sync`, and `invalidate`, but the exact set varies
|
||||||
|
and **`get` is not universal**. Documented `get` / lookup: `session.get`,
|
||||||
|
`session.message.get`, and the "lookup" mentioned for pending items; `project.get`
|
||||||
|
and the lookup for saved project permissions; and `shell.get`. The
|
||||||
|
location-scoped catalogs (agents, commands, integrations, models, providers,
|
||||||
|
references, skills, MCP servers and resources) are documented with `list`,
|
||||||
|
`sync`, and `invalidate` only. Other exceptions: `session.root` / `family` /
|
||||||
|
`cost` / `status` are separate, `location.default()` has no `list`/`get`, and
|
||||||
|
version control uses `vcs.info(...)`. Check the name in the page's example.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
// sessions: list, get, root, family, cost, status, sync, invalidate
|
||||||
|
const rootID = context.data.session.root(sessionID)
|
||||||
|
const cost = context.data.session.cost(sessionID)
|
||||||
|
const status = context.data.session.status(sessionID)
|
||||||
|
await context.data.session.sync(sessionID)
|
||||||
|
context.data.session.invalidate(sessionID)
|
||||||
|
|
||||||
|
// pending inbox items and messages
|
||||||
|
await context.data.session.pending.sync(sessionID)
|
||||||
|
const pending = context.data.session.pending.list(sessionID)
|
||||||
|
await context.data.session.message.sync(sessionID)
|
||||||
|
const messages = context.data.session.message.list(sessionID)
|
||||||
|
|
||||||
|
// permissions, and forms at a location
|
||||||
|
await context.data.session.permission.sync(sessionID)
|
||||||
|
const requests = context.data.session.permission.list(sessionID) ?? []
|
||||||
|
await context.data.session.form.sync(sessionID, location)
|
||||||
|
const forms = context.data.session.form.list(sessionID, location) ?? []
|
||||||
|
await context.data.session.form.reply(reply, location)
|
||||||
|
await context.data.session.form.cancel(cancel, location)
|
||||||
|
|
||||||
|
// projects, shells, location, and version control
|
||||||
|
await context.data.project.sync()
|
||||||
|
await context.data.shell.sync(context.location)
|
||||||
|
await context.data.location.vcs.sync(context.location)
|
||||||
|
const branch = context.data.location.vcs.info(context.location)?.branch.current
|
||||||
|
```
|
||||||
|
|
||||||
|
Location-scoped catalogs — agents, commands, integrations, models, providers,
|
||||||
|
references, skills, MCP servers, MCP resources — all take a `location` and
|
||||||
|
return `?? []` when empty.
|
||||||
|
|
||||||
|
## Attention
|
||||||
|
|
||||||
|
System notification, sound, or both, based on terminal focus.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const result = await context.attention.notify({
|
||||||
|
title: "OpenCode",
|
||||||
|
message: "Session done",
|
||||||
|
notification: { when: "blurred" },
|
||||||
|
sound: { name: "done", volume: 0.5, when: "always" },
|
||||||
|
})
|
||||||
|
// result.ok, result.notification, result.sound, result.skipped
|
||||||
|
```
|
||||||
|
|
||||||
|
## Theme and renderer
|
||||||
|
|
||||||
|
Use semantic theme tokens with OpenTUI elements and pass `context.renderer` to
|
||||||
|
renderer-specific helpers.
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
const Status = () => <text fg={context.theme.text.base}>Ready</text>
|
||||||
|
```
|
||||||
|
|
||||||
|
Inside JSX rendered by a route, dialog, or slot, get the context with
|
||||||
|
`usePlugin`:
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import { usePlugin } from "@opencode/plugin/tui"
|
||||||
|
|
||||||
|
function Status() {
|
||||||
|
const context = usePlugin()
|
||||||
|
return <text fg={context.theme.text.base}>{context.app.version}</text>
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Storage
|
||||||
|
|
||||||
|
`store` persists JSON across restarts and syncs across TUI instances. `memory`
|
||||||
|
survives plugin reloads but dies with the TUI.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const [settings, updateSettings] = context.storage.store("settings", {
|
||||||
|
initial: { compact: false },
|
||||||
|
})
|
||||||
|
await updateSettings((draft) => {
|
||||||
|
draft.compact = true
|
||||||
|
})
|
||||||
|
|
||||||
|
const [state, updateState] = context.storage.memory("state", { initial: { count: 0 } })
|
||||||
|
```
|
||||||
|
|
||||||
|
## Commands and keymaps
|
||||||
|
|
||||||
|
```ts
|
||||||
|
context.keymap.layer(() => ({
|
||||||
|
mode: "global",
|
||||||
|
priority: 10,
|
||||||
|
commands: [
|
||||||
|
{
|
||||||
|
id: "acme.status",
|
||||||
|
title: "Show Acme status",
|
||||||
|
group: "Acme",
|
||||||
|
bind: "ctrl+g",
|
||||||
|
palette: true,
|
||||||
|
slash: { name: "acme", aliases: ["status"], arguments: true },
|
||||||
|
enabled: () => true,
|
||||||
|
suggested: true,
|
||||||
|
run: async (input) => context.ui.toast.show({ message: input ?? "Ready" }),
|
||||||
|
},
|
||||||
|
],
|
||||||
|
bindings: ["acme.status"],
|
||||||
|
}))
|
||||||
|
```
|
||||||
|
|
||||||
|
Call `layer` from `setup` — including after an `await` — or from a component.
|
||||||
|
The **layer factory must be pure**. OpenCode evaluates it once without
|
||||||
|
dependency tracking to validate the initial command shape, then reactively.
|
||||||
|
|
||||||
|
A layer is removed at the first of: the plugin is disabled/reloaded/fails
|
||||||
|
setup, or the component that created it is disposed. A layer may target one
|
||||||
|
renderable and return `false` from a command to continue keyboard dispatch.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
context.keymap.layer(() => ({
|
||||||
|
target: () => panel,
|
||||||
|
commands: [{ bind: "escape", run: (_input, event) => (event ? false : undefined) }],
|
||||||
|
}))
|
||||||
|
```
|
||||||
|
|
||||||
|
Initial shape errors — a palette command with no ID — throw from `layer()`.
|
||||||
|
Binding-parse errors are handled by OpenTUI; errors from later reactive
|
||||||
|
updates follow Solid's rules.
|
||||||
|
|
||||||
|
Dispatch and inspection:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
context.keymap.dispatch("acme.status", "verbose")
|
||||||
|
context.keymap.shortcuts("acme.status")
|
||||||
|
context.keymap.commands()
|
||||||
|
context.keymap.pending()
|
||||||
|
context.keymap.active()
|
||||||
|
const popMode = context.keymap.mode.push("acme-search")
|
||||||
|
popMode()
|
||||||
|
```
|
||||||
|
|
||||||
|
## Dialogs and toasts
|
||||||
|
|
||||||
|
```ts
|
||||||
|
await context.ui.dialog.alert({ title: "Acme", message: "Ready" })
|
||||||
|
|
||||||
|
const confirmed = await context.ui.dialog.confirm({
|
||||||
|
title: "Continue?",
|
||||||
|
message: "Run the Acme action?",
|
||||||
|
label: { confirm: "Run", cancel: "Cancel" },
|
||||||
|
})
|
||||||
|
|
||||||
|
const name = await context.ui.dialog.prompt({ title: "Name", placeholder: "release" })
|
||||||
|
|
||||||
|
const mode = await context.ui.dialog.select({
|
||||||
|
title: "Mode",
|
||||||
|
current: "safe",
|
||||||
|
options: [
|
||||||
|
{ title: "Safe", value: "safe", description: "Ask before changes" },
|
||||||
|
{ title: "Fast", value: "fast", category: "Advanced" },
|
||||||
|
],
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Custom `search` owns matching and order. It runs for **every** query including
|
||||||
|
the empty one, and receives only enabled options.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const project = await context.ui.dialog.select({
|
||||||
|
title: "Projects",
|
||||||
|
options: [
|
||||||
|
{ title: "Alpha", value: "alpha", category: "Recent" },
|
||||||
|
{ title: "Beta", value: "beta", category: "Pinned" },
|
||||||
|
],
|
||||||
|
search: (query, options) =>
|
||||||
|
options
|
||||||
|
.filter((o) => o.title.toLowerCase().includes(query.toLowerCase()))
|
||||||
|
.toSorted((l, r) => r.title.localeCompare(l.title)),
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Select **actions** appear in the footer and run from their keyboard binding, a
|
||||||
|
click, or Tab focus followed by Enter. By default they receive the selected value
|
||||||
|
and are **unavailable without a selection** — use `selection: "none"` for actions
|
||||||
|
that need none. They do not close the dialog or settle the promise.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
await context.ui.dialog.select({
|
||||||
|
title: "Projects",
|
||||||
|
options: [{ title: "Alpha", value: "alpha" }],
|
||||||
|
actions: [
|
||||||
|
{ bind: "ctrl+o", title: "Inspect", onTrigger: (value) => context.ui.toast.show({ message: value }) },
|
||||||
|
{ bind: "ctrl+a", title: "Close", side: "right", selection: "none", onTrigger: () => context.ui.dialog.clear() },
|
||||||
|
],
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
- An action does not close the dialog or settle the promise.
|
||||||
|
- Enter or a click resolves the selected value. Escape, `clear()`, or another
|
||||||
|
dialog resolves `undefined`.
|
||||||
|
- **Do not bind `ctrl+n` or `ctrl+p`.** The dialog reserves them for navigation
|
||||||
|
and its own bindings win.
|
||||||
|
|
||||||
|
Custom JSX dialogs set their own size and close themselves:
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
context.ui.dialog.set({ size: "large", centered: true })
|
||||||
|
context.ui.dialog.show(
|
||||||
|
() => (
|
||||||
|
<box>
|
||||||
|
<text>Acme</text>
|
||||||
|
</box>
|
||||||
|
),
|
||||||
|
() => console.log("closed"),
|
||||||
|
)
|
||||||
|
context.ui.dialog.clear()
|
||||||
|
```
|
||||||
|
|
||||||
|
Toasts take `title`, `message`, `variant`, and `duration`.
|
||||||
|
|
||||||
|
## Markdown
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const unregister = context.markdown.registerCodeBlockRenderer("acme", (_token, render) => render.defaultRender())
|
||||||
|
return unregister
|
||||||
|
```
|
||||||
|
|
||||||
|
## Routes and tabs
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
const unregister = context.ui.router.register({
|
||||||
|
name: "dashboard",
|
||||||
|
render: ({ data }) => <text>{String(data?.title ?? "Acme")}</text>,
|
||||||
|
})
|
||||||
|
context.ui.router.navigate({ type: "plugin", name: "dashboard", data: { title: "Status" } })
|
||||||
|
context.ui.router.navigate({ type: "session", sessionID })
|
||||||
|
context.ui.router.navigate({ type: "home" })
|
||||||
|
```
|
||||||
|
|
||||||
|
```ts
|
||||||
|
if (context.ui.tabs.enabled()) {
|
||||||
|
context.ui.tabs.open(backgroundSessionID) // leaves focus unchanged
|
||||||
|
context.ui.tabs.focus(sessionID) // opens if needed
|
||||||
|
const tabs = context.ui.tabs.list()
|
||||||
|
context.ui.tabs.move(backgroundSessionID, tabs.length - 1)
|
||||||
|
context.ui.tabs.close(sessionID)
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Model
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const selected = context.ui.model.current()
|
||||||
|
const variants = context.ui.model.variant.list()
|
||||||
|
context.ui.model.variant.set("high")
|
||||||
|
context.ui.model.variant.set(undefined) // back to the model default
|
||||||
|
```
|
||||||
|
|
||||||
|
`current()` and `variant.list()` are reactive when read in a Solid computation.
|
||||||
|
`variant.set` returns `false` when no model is selected or the variant does not
|
||||||
|
exist. A common use is replacing the built-in variant cycle:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
context.keymap.layer(() => ({
|
||||||
|
commands: [
|
||||||
|
{
|
||||||
|
id: "acme.variant.cycle",
|
||||||
|
title: "Cycle variants",
|
||||||
|
bind: "tab",
|
||||||
|
run() {
|
||||||
|
const variants = context.ui.model.variant.list()
|
||||||
|
if (variants.length === 0) return
|
||||||
|
const index = variants.indexOf(context.ui.model.current()?.variant ?? "")
|
||||||
|
context.ui.model.variant.set(variants[(index + 1) % variants.length])
|
||||||
|
},
|
||||||
|
},
|
||||||
|
],
|
||||||
|
}))
|
||||||
|
```
|
||||||
|
|
||||||
|
## Slots
|
||||||
|
|
||||||
|
Insert or replace JSX at `app`, `home.footer`, `home.footer.status`,
|
||||||
|
`prompt.footer`, `prompt.footer.status`, `prompt.footer.file`,
|
||||||
|
`session.composer.top`, `sidebar.content`, or `sidebar.footer`.
|
||||||
|
|
||||||
|
Placements: `prepend`, `append`, `before`, `after`, `replace`.
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
return context.ui.slot({
|
||||||
|
append: "sidebar.content",
|
||||||
|
render: ({ sessionID }) => <text>{context.data.session.get(sessionID)?.title}</text>,
|
||||||
|
})
|
||||||
|
|
||||||
|
context.ui.slot({ append: "home.footer.status", render: () => <text>SYNCED</text> })
|
||||||
|
```
|
||||||
|
|
||||||
|
Use `home.footer.status` to add to the built-in footer row **without replacing
|
||||||
|
it**; status contributions appear after health indicators and before the version.
|
||||||
|
|
||||||
|
### Session panels
|
||||||
|
|
||||||
|
Register a contribution to `session.panel`, then open it from a command. The
|
||||||
|
host owns sizing, focus, and full-screen presentation; the plugin owns content.
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import { Show } from "solid-js"
|
||||||
|
|
||||||
|
context.ui.slot({
|
||||||
|
append: "session.panel",
|
||||||
|
render: (panel) => (
|
||||||
|
<Show when={panel.name === "acme.review"}>
|
||||||
|
<ReviewPanel panel={panel} />
|
||||||
|
</Show>
|
||||||
|
),
|
||||||
|
})
|
||||||
|
|
||||||
|
context.ui.slot({
|
||||||
|
append: "app",
|
||||||
|
render: () => {
|
||||||
|
context.keymap.layer(() => ({
|
||||||
|
mode: "global",
|
||||||
|
commands: [
|
||||||
|
{
|
||||||
|
id: "acme.review",
|
||||||
|
title: "Open review",
|
||||||
|
slash: { name: "review" },
|
||||||
|
run: () => context.ui.panel.open("acme.review"),
|
||||||
|
},
|
||||||
|
],
|
||||||
|
}))
|
||||||
|
return null
|
||||||
|
},
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
- Opening outside a session returns `false`.
|
||||||
|
- This is an ordinary slot: all five placements and the existing replacement
|
||||||
|
ordering rules apply. `append` is what lets independently selectable
|
||||||
|
contributions coexist; `replace` still takes over the slot.
|
||||||
|
- Names are **shared selection values, not registered claims**. Use a
|
||||||
|
plugin-prefixed name. Opening a name with no matching renderer leaves the slot
|
||||||
|
empty.
|
||||||
|
- Changing presentation preserves mounted contributions. Closing the panel
|
||||||
|
disposes them; disabling a plugin removes its contributions through normal
|
||||||
|
slot cleanup.
|
||||||
|
- Its keyboard layers and input modes are active only while the panel owns input.
|
||||||
|
- The slot receives reactive `name`, `sessionID`, `width`, `presentation`, and
|
||||||
|
`focused`, plus `focus`, `close`, and `toggleFullscreen`. The host keeps narrow
|
||||||
|
terminals full-screen, so `toggleFullscreen` does nothing until there is room.
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import type { PanelInput } from "@opencode/plugin/tui/context"
|
||||||
|
import { usePlugin } from "@opencode/plugin/tui"
|
||||||
|
|
||||||
|
function ReviewPanel(props: { panel: PanelInput }) {
|
||||||
|
const context = usePlugin()
|
||||||
|
context.keymap.layer(() => ({
|
||||||
|
commands: [{ id: "acme.review.fullscreen", bind: "f", run: props.panel.toggleFullscreen }],
|
||||||
|
}))
|
||||||
|
return <text>Reviewing {props.panel.sessionID}</text>
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
```ts
|
||||||
|
context.ui.panel.open("acme.review", { presentation: "fullscreen" })
|
||||||
|
const current = context.ui.panel.current()
|
||||||
|
context.ui.panel.close()
|
||||||
|
```
|
||||||
|
|
||||||
|
## Formatting
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const displayPath = context.ui.format.path(context.location?.directory ?? "/home/me/project")
|
||||||
|
```
|
||||||
|
|
||||||
|
Abbreviates the home directory.
|
||||||
|
|
||||||
|
## Publish and load
|
||||||
|
|
||||||
|
Expose the TUI plugin through `./tui` and add OpenTUI peers when rendering JSX.
|
||||||
|
|
||||||
|
```json title="package.json"
|
||||||
|
{
|
||||||
|
"name": "opencode-acme-plugin",
|
||||||
|
"type": "module",
|
||||||
|
"exports": {
|
||||||
|
".": "./src/index.ts",
|
||||||
|
"./tui": "./src/tui.tsx"
|
||||||
|
},
|
||||||
|
"dependencies": { "@opencode/plugin": "latest" },
|
||||||
|
"peerDependencies": {
|
||||||
|
"@opentui/core": ">=0.5.8",
|
||||||
|
"@opentui/solid": ">=0.5.8",
|
||||||
|
"solid-js": ">=1.9.0"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Exporting `./tui` beside the main plugin makes the CLI load it automatically.
|
||||||
|
The docs say you **do not need** to add the same package to `cli.json` — the CLI
|
||||||
|
gets the active plugin list from the connected OpenCode server, so this also
|
||||||
|
works when the server is remote.
|
||||||
|
|
||||||
|
Use `cli.json` only for **CLI-only** plugins that run locally in the terminal and
|
||||||
|
must stay active against a remote server:
|
||||||
|
|
||||||
|
```json title="cli.json"
|
||||||
|
{
|
||||||
|
"$schema": "https://opencode.ai/v2/cli.json",
|
||||||
|
"plugins": [
|
||||||
|
"opencode.example",
|
||||||
|
"opencode.example@1.0.0",
|
||||||
|
"@example/opencode-tui",
|
||||||
|
"@example/opencode-tui@1.0.0",
|
||||||
|
"./plugins/status",
|
||||||
|
"../plugins/status",
|
||||||
|
"/home/user/plugins/status",
|
||||||
|
"file:///home/user/plugins/status"
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Entries are processed in order. Prefix an ID or wildcard with `-` to disable
|
||||||
|
matching plugins. The `cli/plugins` page shows `["*", "-opencode.notifications",
|
||||||
|
"-team.*"]` as its example; the explicit meaning of `*` and `.*` is spelled out
|
||||||
|
only on the `plugins` config page, so treat the wildcard semantics here as
|
||||||
|
inferred from that example.
|
||||||
|
|
||||||
|
```json title="cli.json"
|
||||||
|
{ "plugins": ["*", "-opencode.notifications", "-team.*"] }
|
||||||
|
```
|
||||||
|
|
||||||
|
Options use the object form:
|
||||||
|
|
||||||
|
```json title="cli.json"
|
||||||
|
{
|
||||||
|
"$schema": "https://opencode.ai/v2/cli.json",
|
||||||
|
"plugins": [{ "package": "@example/opencode-tui", "options": { "compact": true } }]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
`cli.json` lives at `~/.config/opencode/cli.json`, or
|
||||||
|
`$XDG_CONFIG_HOME/opencode/cli.json`. **There is no project-local CLI settings
|
||||||
|
file** — a `cli.json` next to a project `opencode.json(c)` is not read.
|
||||||
|
(Source: <https://opencode.ai/v2/docs/cli/config>)
|
||||||
|
|
||||||
|
Server plugins belong in `opencode.json(c)`.
|
||||||
|
|
||||||
|
OpenCode also discovers plugins under the global config directory and project
|
||||||
|
`.opencode` directories, each using the published-package layout with server and
|
||||||
|
TUI entrypoints together:
|
||||||
|
|
||||||
|
```text title="Plugin discovery paths"
|
||||||
|
<global-config>/plugins/status/index.ts

# Effect Plugins
|
||||||
|
|
||||||
|
**Docs: <https://opencode.ai/v2/docs/build/plugins/effect/>** — fetch this page
|
||||||
|
before writing an Effect plugin. This file is a summary of it.
|
||||||
|
**Template: `../templates/effect-plugin.ts`**
|
||||||
|
|
||||||
|
`@opencode/plugin/effect` is the Effect-native flavor of the server plugin API.
|
||||||
|
Context operations return Effects or Streams, callbacks return Effects, and
|
||||||
|
lifetime is a `Scope`. Use it when the project already uses Effect. Otherwise
|
||||||
|
use the Promise flavor in `SKILL.md`.
|
||||||
|
|
||||||
|
## Install
|
||||||
|
|
||||||
|
OpenCode provides `effect`, `effect/*`, and `@opencode/plugin` at runtime. Do
|
||||||
|
**not** bundle them. The page says to install `effect` and `@opencode/plugin` as
|
||||||
|
peer/dev dependencies for local type-checking and testing.
|
||||||
|
|
||||||
|
```sh
|
||||||
|
bun add --peer @opencode/plugin effect
|
||||||
|
```
|
||||||
|
|
||||||
|
```json title="package.json"
|
||||||
|
{
|
||||||
|
"peerDependencies": { "effect": ">=4.0.0-rc.112" }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
If you bundle with a bundler, mark `effect` and `effect/*` external. OpenCode
|
||||||
|
redirects these imports (including from your `node_modules`) to the host's
|
||||||
|
runtime so fibers, loggers, and `Schema` parsers share one copy. Dependencies
|
||||||
|
built on another Effect major (e.g. Effect 3) are **not** supported. Importing a
|
||||||
|
private `effect/internal/*` path fails to load with an error naming the path.
|
||||||
|
|
||||||
|
## Shape
|
||||||
|
|
||||||
|
```ts
|
||||||
|
import { Plugin } from "@opencode/plugin/effect"
|
||||||
|
import { Effect } from "effect"
|
||||||
|
|
||||||
|
export default Plugin.define({
|
||||||
|
id: "example",
|
||||||
|
effect: (ctx) =>
|
||||||
|
Effect.gen(function* () {
|
||||||
|
yield* ctx.storage.set("loaded", true)
|
||||||
|
}),
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Use `effect:`, not `setup:`. Exporting from `.opencode/plugins/` loads it
|
||||||
|
automatically; packages use the same `plugins` config as Promise plugins.
|
||||||
|
|
||||||
|
## Lifecycle
|
||||||
|
|
||||||
|
The scope closes on reload or unload, releasing registrations, scoped fibers, and
|
||||||
|
finalizers together.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
effect: (ctx) =>
|
||||||
|
Effect.gen(function* () {
|
||||||
|
yield* Effect.addFinalizer(() => Effect.logInfo("unloaded"))
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Background work uses scoped fibers; the scope interrupts them at cleanup.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
yield* Effect.repeat(
|
||||||
|
storage.set("heartbeat", { time: Date.now() }),
|
||||||
|
{ schedule: Schedule.spaced("1 minute") },
|
||||||
|
).pipe(Effect.forkScoped)
|
||||||
|
```
|
||||||
|
|
||||||
|
`Effect.repeat` takes an Effect **value**, not a function.
|
||||||
|
|
||||||
|
## Key differences from Promise plugins
|
||||||
|
|
||||||
|
| Aspect | Promise | Effect |
|
||||||
|
| ------ | ------- | ------ |
|
||||||
|
| Entry | `setup(ctx)` returning `Promise`/cleanup fn | `effect(ctx)` returning `Effect` |
|
||||||
|
| Reads | `await ctx.model.list()` | `yield* ctx.model.list()` |
|
||||||
|
| Transforms | `await ctx.model.transform(cb)` — cb sync | `yield* ctx.model.transform(cb)` — cb **still sync** |
|
||||||
|
| Cleanup | `return () => {}` | `Effect.addFinalizer` / `forkScoped` |
|
||||||
|
| Events | `for await (…)` + manual `AbortController` | `Stream` + `forkScoped` |
|
||||||
|
| Tool I/O | raw JSON Schema | Effect `Schema` |
|
||||||
|
| Hooks | no rejection API documented for tool hooks | `Effect.fail(new Tool.Error(...))` |
|
||||||
|
| Registration | `await reg.dispose()` | `yield* reg.dispose` |
|
||||||
|
|
||||||
|
`Hooks<Spec, Failures>` and `Transform<Input>` are the shared registration types.
|
||||||
|
Both return an Effect that requires the plugin scope, which is why
|
||||||
|
`transform`/`hook`/`dispose` are all yieldable and scoped:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
type Hooks<Spec, Failures extends Record<keyof Spec, unknown> = Record<keyof Spec, never>> = <Name extends keyof Spec>(
|
||||||
|
name: Name,
|
||||||
|
callback: (input: Spec[Name]) => Effect.Effect<void, Failures[Name]>,
|
||||||
|
) => Effect.Effect<Registration, never, Scope.Scope>
|
||||||
|
|
||||||
|
type Transform<Input> = (callback: (input: Input) => void) => Effect.Effect<Registration, never, Scope.Scope>
|
||||||
|
```
|
||||||
|
|
||||||
|
These are the page's simplified shared types. They are **not** the complete
|
||||||
|
signature for the session domain: the page's session hook type is
|
||||||
|
`SessionHookDomain { readonly hook: ModelHooks<SessionHooks> }`, `ModelHooks` is
|
||||||
|
not defined on the page, and the page's own examples pass a third
|
||||||
|
`{ providerID }` argument that the `Hooks` type above does not accept. Trust the
|
||||||
|
page's examples over the simplified type.
|
||||||
|
|
||||||
|
The transform callback is still synchronous in both flavors. It must not return
|
||||||
|
an Effect or a Promise.
|
||||||
|
|
||||||
|
Result shape is **per operation, not per flavor**. Some reads are enveloped and
|
||||||
|
some are not, in both flavors — check the doc example for the call you are using.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
// enveloped
|
||||||
|
const models = yield* ctx.model.list().pipe(Effect.orDie)
|
||||||
|
models.data.length
|
||||||
|
|
||||||
|
// returned directly
|
||||||
|
const created = yield* ctx.session.create({ title: "Review" }).pipe(Effect.orDie)
|
||||||
|
created.id
|
||||||
|
const settings = yield* ctx.storage.get("settings")
|
||||||
|
```
|
||||||
|
|
||||||
|
The page states direct returns for storage ("Storage accepts Effect's JSON type
|
||||||
|
and returns Effects directly"), for `integration.connection.active` (`Effect<ConnectionInfo | undefined>`) and
|
||||||
|
`integration.connection.resolve` (a `Credential.Value | undefined`), and for
|
||||||
|
`ToolDomain.list`
|
||||||
|
(`Effect<readonly (Tool.Info & { id: string })[]>`); editor `list()` calls also
|
||||||
|
return plain arrays. For everything else, mirror the page's own example rather
|
||||||
|
than assuming either shape.
|
||||||
|
|
||||||
|
Many examples in the page pipe reads through `Effect.orDie` to drop the error
|
||||||
|
channel, then read `.data` — copy that shape when the example uses it.
|
||||||
|
|
||||||
|
## Transforms
|
||||||
|
|
||||||
|
```ts
|
||||||
|
effect: (ctx) =>
|
||||||
|
Effect.gen(function* () {
|
||||||
|
const provider = ctx.provider
|
||||||
|
const source = { providers: yield* loadFromSource() }
|
||||||
|
|
||||||
|
yield* provider.transform((editor) => {
|
||||||
|
source.providers.forEach((p) => editor.add(p))
|
||||||
|
})
|
||||||
|
|
||||||
|
yield* Effect.repeat(
|
||||||
|
Effect.gen(function* () {
|
||||||
|
source.providers = yield* loadFromSource()
|
||||||
|
yield* provider.reload()
|
||||||
|
}),
|
||||||
|
{ schedule: Schedule.spaced("1 minute") },
|
||||||
|
).pipe(Effect.forkScoped)
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Rebuild, replay-order, and no-implicit-watch semantics are identical to the
|
||||||
|
Promise flavor. See `SKILL.md`.
|
||||||
|
|
||||||
|
## Tools
|
||||||
|
|
||||||
|
Effect plugins register tools with Effect `Schema` instead of raw JSON Schema,
|
||||||
|
and the executor returns typed output.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
effect: (ctx) =>
|
||||||
|
Effect.gen(function* () {
|
||||||
|
yield* ctx.tool.transform((editor) => {
|
||||||
|
editor.namespace({ name: "acme", description: "Customer account tools" })
|
||||||
|
editor.add({
|
||||||
|
name: "greeting",
|
||||||
|
description: "Create a greeting",
|
||||||
|
input: Schema.Struct({ name: Schema.String }),
|
||||||
|
output: Schema.Struct({ greeting: Schema.String }),
|
||||||
|
options: { namespace: "acme", codemode: true },
|
||||||
|
execute: ({ name }, context) =>
|
||||||
|
Effect.gen(function* () {
|
||||||
|
yield* context.progress({ status: "greeting" })
|
||||||
|
return { output: { greeting: `Hello ${name}!` } }
|
||||||
|
}),
|
||||||
|
})
|
||||||
|
})
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Return `{ output }` for typed output — that is the shape the page's executor
|
||||||
|
example uses. The page also says an executor may return "typed output, display
|
||||||
|
content, or metadata" without showing those other shapes, so confirm on the page
|
||||||
|
before relying on a `{ content }` form in an Effect plugin.
|
||||||
|
Effective-name rules (`acme_greeting`), `update`/`remove` semantics, snapshot
|
||||||
|
behavior, and `dispose` are the same as the Promise flavor.
|
||||||
|
|
||||||
|
## Hooks
|
||||||
|
|
||||||
|
Callbacks return Effects. Registration stays in the plugin scope.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
effect: (ctx) =>
|
||||||
|
Effect.gen(function* () {
|
||||||
|
const session = ctx.session
|
||||||
|
|
||||||
|
yield* session.hook("context", (event) =>
|
||||||
|
Effect.sync(() => {
|
||||||
|
event.system.push({ type: "text", text: "Keep the review focused on correctness." })
|
||||||
|
delete event.tools.write
|
||||||
|
}),
|
||||||
|
)
|
||||||
|
|
||||||
|
yield* session.hook("compaction", (event) =>
|
||||||
|
Effect.map(summarize(event.messages), (summary) => {
|
||||||
|
event.result = { summary }
|
||||||
|
}),
|
||||||
|
)
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Failing a tool hook with `Tool.Error`:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
yield* ctx.tool.hook("execute.before", (event) =>
|
||||||
|
event.tool === "write"
|
||||||
|
? Effect.fail(new Tool.Error({ message: "Writes are disabled" }))
|
||||||
|
: Effect.logDebug("tool input", { tool: event.tool, input: event.input }),
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
Hook names, event fields, ordering, and override precedence are the same
|
||||||
|
**where the Effect page documents them** — but the two flavors do not have the
|
||||||
|
same hook set:
|
||||||
|
|
||||||
|
- The Effect `SessionHooks` type lists `context`, `compaction`, `generate`,
|
||||||
|
`title`, `model.request`, `http.request`, `http.response`, the three
|
||||||
|
`experimental.ws.*`, and `retry`. **It has no `prompt` hook.** Do not carry
|
||||||
|
the Promise `prompt` example over without confirming it on this page.
|
||||||
|
- Provider scoping (`{ providerID: "anthropic" }` as a third argument) is
|
||||||
|
documented here for `model.request`, `experimental.ws.handshake`, and
|
||||||
|
`experimental.ws.send`. The simplified `Hooks<Spec, Failures>` type quoted
|
||||||
|
earlier in this file does not show that third parameter, so do not treat it as
|
||||||
|
the complete signature.
|
||||||
|
|
||||||
|
For the request-hook rules that both flavors share, see `SKILL.md`.
|
||||||
|
|
||||||
|
Effect callbacks use Effect interruption instead of `signal`; the other
|
||||||
|
`experimental.ws.*` and `retry` hooks behave as documented there.
|
||||||
|
|
||||||
|
## Events
|
||||||
|
|
||||||
|
`ctx.event.subscribe()` is a `Stream`. Fork it in scope for automatic
|
||||||
|
interruption — no `AbortController` needed.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
yield* ctx.event.subscribe().pipe(
|
||||||
|
Stream.tap((item) => Effect.logDebug("OpenCode event", { type: item.type })),
|
||||||
|
Stream.runDrain,
|
||||||
|
Effect.forkScoped,
|
||||||
|
)
|
||||||
|
|
||||||
|
yield* ctx.event.subscribe().pipe(
|
||||||
|
Stream.filter((item) => item.type === "config.updated"),
|
||||||
|
Stream.runForEach(() => Effect.logInfo("configuration changed")),
|
||||||
|
Effect.forkScoped,
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Branded values
|
||||||
|
|
||||||
|
The re-exported Effect schema constructors produce branded IDs rather than bare
|
||||||
|
strings. Narrow and construct with them:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const providerID = Provider.ID.make("acme")
|
||||||
|
const modelID = Model.ID.make("claude-sonnet-4-5")
|
||||||
|
|
||||||
|
const created = yield* ctx.session.create({ title: "Review" }).pipe(Effect.orDie)
|
||||||
|
|
||||||
|
yield* ctx.session
|
||||||
|
.switchModel({ sessionID: created.id, model: { providerID, id: modelID } })
|
||||||
|
.pipe(Effect.orDie)
|
||||||
|
|
||||||
|
yield* ctx.skill.transform((editor) => {
|
||||||
|
editor.add(Skill.Info.make({
|
||||||
|
id: Skill.ID.make("review"),
|
||||||
|
name: Skill.Name.make("Review"),
|
||||||
|
description: "Review the current changes",
|
||||||
|
path: "/workspace/.opencode/skills/review/SKILL.md",
|
||||||
|
content: "Review the current changes for correctness and missing tests.",
|
||||||
|
}))
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
## Commands
|
||||||
|
|
||||||
|
The command transform is add-only here too. The executor returns an Effect.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
yield* command.transform((editor) => {
|
||||||
|
editor.add({
|
||||||
|
name: "security-review",
|
||||||
|
description: "Review changes for security issues",
|
||||||
|
execute: (input) =>
|
||||||
|
session.prompt({
|
||||||
|
...input.prompt,
|
||||||
|
sessionID: input.sessionID,
|
||||||
|
text: `Review these changes for security issues.\n\n${input.prompt.text}`,
|
||||||
|
delivery: input.delivery,
|
||||||
|
}).pipe(Effect.asVoid),
|
||||||
|
})
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
## Integrations
|
||||||
|
|
||||||
|
OAuth method callbacks are Effects and may acquire scoped resources.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
yield* integration.transform((editor) => {
|
||||||
|
editor.method.update({
|
||||||
|
integrationID: "acme",
|
||||||
|
method: { id: "device", type: "oauth", label: "Sign in with Acme" },
|
||||||
|
authorize: () =>
|
||||||
|
Effect.succeed({
|
||||||
|
mode: "code",
|
||||||
|
url: "https://acme.example/device",
|
||||||
|
instructions: "Enter the displayed code",
|
||||||
|
callback: (code) => exchangeCode(code),
|
||||||
|
}),
|
||||||
|
})
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
`authorize` returns `mode: "auto"` (callback is the Effect that performs the
|
||||||
|
flow) or `mode: "code"` (callback takes the code). The Effect's `R` may include
|
||||||
|
`Scope.Scope`, so it can hold scoped resources for the attempt's duration.
|
||||||
|
|
||||||
|
## Context shape
|
||||||
|
|
||||||
|
`Context` declares `app`, `location`, `options`, and these domains: `agent`,
|
||||||
|
`aisdk`, `command`, `event`, `experimental`, `integration`, `mcp`, `model`,
|
||||||
|
`generate`, `permission`, `plugin`, `provider`, `reference`, `rpc`, `session`,
|
||||||
|
`shell`, `skill`, `storage`, `tool`, `vcs`, `websearch`, `worktree`.
|
||||||
|
|
||||||
|
Three narrowed members worth noting:
|
||||||
|
|
||||||
|
- `experimental` is only
|
||||||
|
`{ terminal: Pick<ExperimentalApi<unknown>["persistentPty"], "read"> }`. The
|
||||||
|
narrowed member is `experimental.terminal`, not `experimental`.
|
||||||
|
- `plugin` is only `Pick<PluginApi<unknown>, "list">`; `list` reports active,
|
||||||
|
failed, and resolved plugins, so filter in a pipeline when you need only
|
||||||
|
active ones. The page's example filters on `item.status === "active"`, but
|
||||||
|
the shipped `Plugin.Info` nests that as `state.status` — trust the type.
|
||||||
|
- `vcs` omits `init` as a client method, but a registered VCS **definition** may
|
||||||
|
still implement it.
|
||||||
|
|
||||||
|
This is the **Effect** `Context`. Do not assume it matches the Promise context
|
||||||
|
member for member — this page does not state that they are identical, and
|
||||||
|
`aisdk` appears here with no Promise-page counterpart.
|
||||||
|
|
||||||
|
The context exposes the Effect client plus plugin-only transforms, hooks,
|
||||||
|
storage, reloads, and options. It does **not** expose OpenCode's private Core
|
||||||
|
services.
|
||||||
|
|
||||||
|
## Plugin type
|
||||||
|
|
||||||
|
```ts
|
||||||
|
interface Plugin<R = Scope.Scope> {
|
||||||
|
readonly id: string
|
||||||
|
readonly effect: (context: Context) => Effect.Effect<void, never, R>
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
The `R` defaults to `Scope.Scope`, so registrations and scoped fibers are
|
||||||
|
released when the plugin scope closes.
|
||||||
|
|
||||||
|
Two runtime caveats:
|
||||||
|
|
||||||
|
- Only **public** `effect` subpaths are provided. Importing an `internal` module
|
||||||
|
fails to load with an error naming the path.
|
||||||
|
- The compiled OpenCode binary omits the Scalar/Swagger UI assets used by
|
||||||
|
Effect's HTTP API doc pages; serving those from a plugin shows a notice.
|
||||||
|
|
||||||
|
## Publish
|
||||||
|
|
||||||
|
Declare `effect` as a `peerDependency` and export the Effect implementation from
|
||||||
|
the main entrypoint.
|
||||||
|
|
||||||
|
```json title="package.json"
|
||||||
|

# RPC Plugins
|
||||||
|
|
||||||
|
**Promise docs: <https://opencode.ai/v2/docs/build/plugins/rpc/>**
|
||||||
|
**Effect docs: <https://opencode.ai/v2/docs/build/plugins/effect/rpc/>**
|
||||||
|
**Templates: `../templates/rpc.ts` + `rpc-implementation.ts` (Promise),
|
||||||
|
`../templates/rpc-effect.ts` + `rpc-implementation-effect.ts` (Effect)**
|
||||||
|
|
||||||
|
RPC lets a plugin expose custom **methods and events that run on the server** and
|
||||||
|
can be called by other plugins or by clients. It is a contract plus a
|
||||||
|
registration — the contract file itself contains no implementation.
|
||||||
|
|
||||||
|
There are two flavors with the same shape but different types and calling
|
||||||
|
conventions. Check the differences table at the end before copying a snippet,
|
||||||
|
and confirm each identifier on the page for your flavor.
|
||||||
|
|
||||||
|
## Define (Promise page)
|
||||||
|
|
||||||
|
Everything from here down to the Effect section documents the **Promise** page
|
||||||
|
(<https://opencode.ai/v2/docs/build/plugins/rpc/>). The Effect flavor follows below.
|
||||||
|
|
||||||
|
Use `Rpc.define` in a file that other packages can import without loading your
|
||||||
|
plugin. Publish it as the `./rpc` export.
|
||||||
|
|
||||||
|
```ts title="src/rpc.ts"
|
||||||
|
import { Rpc } from "@opencode/plugin/rpc"
|
||||||
|
|
||||||
|
export const Acme = Rpc.define({
|
||||||
|
id: "acme",
|
||||||
|
methods: {
|
||||||
|
search: {
|
||||||
|
input: {
|
||||||
|
type: "object",
|
||||||
|
properties: { query: { type: "string" } },
|
||||||
|
required: ["query"],
|
||||||
|
additionalProperties: false,
|
||||||
|
},
|
||||||
|
output: {
|
||||||
|
type: "object",
|
||||||
|
properties: { text: { type: "string" } },
|
||||||
|
required: ["text"],
|
||||||
|
additionalProperties: false,
|
||||||
|
},
|
||||||
|
errors: {
|
||||||
|
not_found: {
|
||||||
|
type: "object",
|
||||||
|
properties: { query: { type: "string" } },
|
||||||
|
required: ["query"],
|
||||||
|
additionalProperties: false,
|
||||||
|
},
|
||||||
|
},
|
||||||
|
},
|
||||||
|
},
|
||||||
|
events: {
|
||||||
|
updated: {
|
||||||
|
schema: {
|
||||||
|
type: "object",
|
||||||
|
properties: { itemID: { type: "string" }, text: { type: "string" } },
|
||||||
|
required: ["itemID", "text"],
|
||||||
|
additionalProperties: false,
|
||||||
|
},
|
||||||
|
},
|
||||||
|
},
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
The RPC page does not describe what `id` affects; it only shows received event
|
||||||
|
types arriving prefixed — `rpc.acme.updated` for an event named `updated` under `id: "acme"` —
|
||||||
|
and does not otherwise describe how `id` affects method routing, so do not rely
|
||||||
|
on that beyond what the page states. Pick a name that will not collide.
|
||||||
|
|
||||||
|
The `./rpc` export is described as optional on the **plugins** page
|
||||||
|
(<https://opencode.ai/v2/docs/build/plugins>), not on the RPC page:
|
||||||
|
|
||||||
|
```json title="package.json"
|
||||||
|
{
|
||||||
|
"name": "opencode-acme-plugin",
|
||||||
|
"version": "1.0.0",
|
||||||
|
"type": "module",
|
||||||
|
"exports": {
|
||||||
|
".": "./src/index.ts",
|
||||||
|
"./rpc": "./src/rpc.ts"
|
||||||
|
},
|
||||||
|
"dependencies": { "@opencode/plugin": "latest" }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Schemas (Promise page)
|
||||||
|
|
||||||
|
Two formats are supported:
|
||||||
|
|
||||||
|
- **JSON Schema** — simple, no dependencies. Values are `unknown` in
|
||||||
|
TypeScript, so **narrow them before use**.
|
||||||
|
- **Any Standard Schema validator** — Zod, Valibot, ArkType. Types are inferred.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
import * as z from "zod"
|
||||||
|
|
||||||
|
search: { input: z.object({ query: z.string() }), output: z.object({ text: z.string() }) }
|
||||||
|
```
|
||||||
|
|
||||||
|
Omit `input` or `output` when the method takes or returns nothing.
|
||||||
|
|
||||||
|
## Errors (Promise page)
|
||||||
|
|
||||||
|
Add an `errors` map for expected failures. Each key becomes the error's `type`;
|
||||||
|
its schema defines the error's `data`. Names beginning with `rpc.` are reserved
|
||||||
|
by OpenCode.
|
||||||
|
|
||||||
|
## Events (Promise page)
|
||||||
|
|
||||||
|
Top-level `events` map. Event data must be an object — scalars, arrays, `null`,
|
||||||
|
and `undefined` are invalid. Use an empty object schema for no data:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
events: { refreshed: { schema: { type: "object", additionalProperties: false } } }
|
||||||
|
```
|
||||||
|
|
||||||
|
## Implement (Promise page)
|
||||||
|
|
||||||
|
Register inside `setup`:
|
||||||
|
|
||||||
|
```ts title="src/index.ts"
|
||||||
|
import { Plugin } from "@opencode/plugin"
|
||||||
|
import { Acme } from "./rpc.js" // your contract file, e.g. src/rpc.ts
|
||||||
|
|
||||||
|
export default Plugin.define({
|
||||||
|
id: "acme-plugin",
|
||||||
|
async setup(ctx) {
|
||||||
|
const registration = await ctx.rpc.register(Acme, {
|
||||||
|
search: async (input, context) => {
|
||||||
|
const { query } = input as { query: string }
|
||||||
|
const text = await findText(query, { signal: context.signal })
|
||||||
|
if (!text) return context.error("not_found", "Result not found", { query })
|
||||||
|
return { text }
|
||||||
|
},
|
||||||
|
})
|
||||||
|
|
||||||
|
// the same plugin can call its own RPC
|
||||||
|
const acme = ctx.rpc(Acme)
|
||||||
|
const result = await acme.search({ query: "hello" })
|
||||||
|
|
||||||
|
await registration.events.emit("updated", { itemID: "item-1", text: "ready" })
|
||||||
|
},
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
The second argument gives `signal` for cancellation and `context.error(...)` for
|
||||||
|
declared errors — return it or throw it. One plugin may register several RPCs;
|
||||||
|
the page states that disposing the registration removes it.
|
||||||
|
|
||||||
|
## Call (Promise page)
|
||||||
|
|
||||||
|
### From a client over HTTP
|
||||||
|
|
||||||
|
```ts
|
||||||
|
import { OpenCode } from "@opencode/client"
|
||||||
|
import { Acme } from "opencode-acme-plugin/rpc"
|
||||||
|
|
||||||
|
const client = OpenCode.make({ baseUrl: "http://localhost:4096" })
|
||||||
|
const acme = client.rpc(Acme)
|
||||||
|
const result = await acme.search({ query: "hello" })
|
||||||
|
```
|
||||||
|
|
||||||
|
### From another plugin
|
||||||
|
|
||||||
|
Plugins already hold a client. A TUI plugin uses `context.client`:
|
||||||
|
|
||||||
|
```ts title="src/tui.ts"
|
||||||
|
import { Plugin } from "@opencode/plugin/tui"
|
||||||
|
import { Acme } from "opencode-acme-plugin/rpc"
|
||||||
|
|
||||||
|
export default Plugin.define({
|
||||||
|
id: "acme-tui",
|
||||||
|
async setup(context) {
|
||||||
|
const acme = context.client.rpc(Acme)
|
||||||
|
const result = await acme.search({ query: "hello" })
|
||||||
|
console.log(result)
|
||||||
|
},
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
## Subscribe (Promise page)
|
||||||
|
|
||||||
|
Promise flavor. Callback form returns an unsubscribe function:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const unsubscribe = acme.events.on("updated", (event) => {
|
||||||
|
console.log(event.type, event.location.directory, event.data.text)
|
||||||
|
})
|
||||||
|
unsubscribe()
|
||||||
|
```
|
||||||
|
|
||||||
|
Async iterable form:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
for await (const event of acme.events.subscribe("updated")) {
|
||||||
|
console.log(event.data.text)
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Details stated on the Promise page:
|
||||||
|
|
||||||
|
- Subscribe with the **local** name (`updated`). The received `type` is
|
||||||
|
**prefixed** (`rpc.acme.updated`).
|
||||||
|
- Every event carries `data` and `location`.
|
||||||
|
- Subscriptions are **live only** — a disconnected subscriber misses events.
|
||||||
|
- Plugin unload closes its subscriptions.
|
||||||
|
- External clients receive events from **every** location, so check
|
||||||
|
`event.location`. The server plugin must still be configured and running.
|
||||||
|
|
||||||
|
## Effect flavor
|
||||||
|
|
||||||
|
The Effect page
|
||||||
|
(<https://opencode.ai/v2/docs/build/plugins/effect/rpc/>) has the same contract
|
||||||
|
shape but Effect types and conventions. `Rpc.define` is imported from
|
||||||
|
`@opencode/plugin/rpc` here too — not from `@opencode/plugin/effect`.
|
||||||
|
|
||||||
|
```ts title="src/rpc.ts"
|
||||||
|
import { Rpc } from "@opencode/plugin/rpc"
|
||||||
|
import { Schema } from "effect"
|
||||||
|
|
||||||
|
export const Acme = Rpc.define({
|
||||||
|
id: "acme",
|
||||||
|
methods: {
|
||||||
|
search: {
|
||||||
|
input: Schema.Struct({ query: Schema.String }),
|
||||||
|
output: Schema.Struct({ text: Schema.String }),
|
||||||
|
errors: { not_found: Schema.Struct({ query: Schema.String }) },
|
||||||
|
},
|
||||||
|
},
|
||||||
|
events: {
|
||||||
|
updated: {
|
||||||
|
schema: Schema.Struct({ itemID: Schema.String, text: Schema.String }),
|
||||||
|
},
|
||||||
|
},
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Effect Schema validates and infers types, so no casts. The page also states that
|
||||||
|
JSON Schema and Standard Schema are supported, so an Effect contract is not
|
||||||
|
restricted to Effect Schema.
|
||||||
|
|
||||||
|
Registration happens inside the plugin `effect`, not `setup`:
|
||||||
|
|
||||||
|
```ts title="src/index.ts"
|
||||||
|
import { Plugin } from "@opencode/plugin/effect"
|
||||||
|
import { Effect } from "effect"
|
||||||
|
import { Acme } from "./rpc.js"
|
||||||
|
|
||||||
|
export default Plugin.define({
|
||||||
|
id: "acme-effect-plugin",
|
||||||
|
effect: (ctx) =>
|
||||||
|
Effect.gen(function* () {
|
||||||
|
const registration = yield* ctx.rpc.register(Acme, {
|
||||||
|
search: ({ query }, context) =>
|
||||||
|
findText(query).pipe(
|
||||||
|
Effect.flatMap((text) =>
|
||||||
|
text
|
||||||
|
? Effect.succeed({ text })
|
||||||
|
: Effect.fail(context.error("not_found", "Result not found", { query })),
|
||||||
|
),
|
||||||
|
),
|
||||||
|
})
|
||||||
|
|
||||||
|
const acme = ctx.rpc(Acme)
|
||||||
|
const result = yield* acme.search({ query: "hello" })
|
||||||
|
|
||||||
|
yield* registration.events.emit("updated", { itemID: "item-1", text: result.text })
|
||||||
|
}).pipe(Effect.orDie),
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Input arrives already decoded, so the handler destructures instead of casting.
|
||||||
|
A declared error is raised with `Effect.fail(context.error(type, message, data))`.
|
||||||
|
`context.signal` is **not** mentioned on the Effect page.
|
||||||
|
|
||||||
|
Calling over HTTP needs the Effect client plus an HTTP client layer:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
import { OpenCode } from "@opencode/client/effect"
|
||||||
|
import { Effect } from "effect"
|
||||||
|
import { FetchHttpClient } from "effect/unstable/http"
|
||||||
|
import { Acme } from "opencode-acme-plugin/rpc"
|
||||||
|
|
||||||
|
const program = Effect.gen(function* () {
|
||||||
|
const client = yield* OpenCode.make({ baseUrl: "http://localhost:4096" })
|
||||||
|
const acme = client.rpc(Acme)
|
||||||
|
return yield* acme.search({ query: "hello" })
|
||||||
|
})
|
||||||
|
|
||||||
|
const result = await Effect.runPromise(program.pipe(Effect.provide(FetchHttpClient.layer)))
|
||||||
|
```
|
||||||
|
|
||||||
|
Subscriptions are a Stream; `events.on` is not mentioned on this page:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
import { Effect, Stream } from "effect"
|
||||||
|
|
||||||
|
const acme = ctx.rpc(Acme)
|
||||||
|
yield* acme.events.subscribe("updated").pipe(
|
||||||
|
Stream.runForEach((event) => Effect.logInfo(event.data.text)),
|
||||||
|
Effect.forkScoped,
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
"Subscriptions are live only and close when Stream consumption stops."
|
||||||
|
|
||||||
|
## Promise vs Effect
|
||||||
|
|
||||||
|
| Aspect | Promise | Effect |
|
||||||
|
| ------ | ------- | ------ |
|
||||||
|
| `Rpc.define` import | `@opencode/plugin/rpc` | `@opencode/plugin/rpc` (same) |
|
||||||
|
| Schemas | JSON Schema or Standard Schema; JSON Schema values are `unknown`, narrow them | Effect `Schema`, types inferred. JSON Schema and Standard Schema also supported |
|
||||||
|
| Handler signature | `async (input, context)`, then `input as { … }` | `({ … }, context) => Effect`, input already decoded |
|
||||||
|
| Success | `return { text }` | `Effect.succeed({ text })` |
|
||||||
|
| Declared error | `return context.error("not_found", msg, data)` | `Effect.fail(context.error("not_found", msg, data))` |
|
||||||
|
| Cancellation | pass `context.signal` to the work | not documented on that page; use interruption |
|
||||||
|
| Registered in | `await ctx.rpc.register` in `async setup` | `yield* ctx.rpc.register` in `Effect.gen` under `effect:` |
|
||||||
|
| Emit | `await registration.events.emit(…)` | `yield* registration.events.emit(…)` |
|
||||||
|
| HTTP client | `OpenCode.make({…})` from `@opencode/client` | `yield* OpenCode.make({…})` from `@opencode/client/effect`, plus `FetchHttpClient.layer` |
|
||||||
|
| Another plugin calls it | TUI plugin: `context.client.rpc(Acme)` | Effect plugin: `ctx.rpc(Acme)` |
|
||||||
|
| Subscribe | `events.on(…)` → unsubscribe fn, or `events.subscribe(…)` → async iterable | `events.subscribe(…)` → Stream + `Effect.forkScoped` |
|
||||||
|
|
||||||
|
Stated only on the **Promise** page — do not assume these carry over to the
|
||||||
|
Effect flavor without checking that page: `rpc.`-prefixed error names being
|
||||||
|
reserved, the "scalars, arrays, `null`, and `undefined` are not valid event
|
||||||
|
data" rule and its empty-object-schema form, the prefixed `rpc.acme.updated`
|
||||||
|
type, `event.location`, plugin unload closing subscriptions, `events.on`, and
|
||||||
|
disposing the registration.

# Templates
|
||||||
|
|
||||||
|
Starter files transcribed from the OpenCode V2 doc pages. **Copy one and fill in
|
||||||
|
the blanks** rather than writing a plugin from scratch.
|
||||||
|
|
||||||
|
| Template | Use for | Source doc |
|
||||||
|
| -------- | ------- | ---------- |
|
||||||
|
| `promise-plugin.ts` | Server plugin, Promise flavor (default) | <https://opencode.ai/v2/docs/build/plugins> |
|
||||||
|
| `effect-plugin.ts` | Server plugin, Effect-native | <https://opencode.ai/v2/docs/build/plugins/effect/> |
|
||||||
|
| `rpc.ts` | RPC contract, Promise flavor (copy to `src/rpc.ts`) | <https://opencode.ai/v2/docs/build/plugins/rpc/> |
|
||||||
|
| `rpc-implementation.ts` | RPC registration + calls, Promise | <https://opencode.ai/v2/docs/build/plugins/rpc/> |
|
||||||
|
| `rpc-effect.ts` | RPC contract, Effect flavor | <https://opencode.ai/v2/docs/build/plugins/effect/rpc/> |
|
||||||
|
| `rpc-implementation-effect.ts` | RPC registration + calls, Effect | <https://opencode.ai/v2/docs/build/plugins/effect/rpc/> |
|
||||||
|
| `tui-plugin.tsx` | TUI / CLI plugin | <https://opencode.ai/v2/docs/build/plugins/cli/> |
|
||||||
|
| `opencode-plugin-config.jsonc` | `plugins` in `opencode.json(c)` | <https://opencode.ai/v2/docs/plugins> |
|
||||||
|
| `package.json` | Publishing a plugin package (strict JSON) | <https://opencode.ai/v2/docs/build/plugins> |
|
||||||
|
| `package-json.md` | Publishing guidance, peer deps, entrypoints | build/plugins, build/plugins/effect, build/plugins/cli |
|
||||||
|
| `README.md` | This index | — |
|
||||||
|
|
||||||
|
`package.json` is strict JSON with no comments, because Node, bun, npm, and
|
||||||
|
bundlers parse it with a strict parser. Publishing guidance therefore lives in
|
||||||
|
`package-json.md` rather than inside the manifest.
|
||||||
|
|
||||||
|
The two RPC template pairs are **not** interchangeable: same contract shape,
|
||||||
|
different schema dialect, handler signature, and registration entrypoint. See the
|
||||||
|
Promise-vs-Effect table in `../references/rpc.md`.
|
||||||
|
|
||||||
|
## Before you write code
|
||||||
|
|
||||||
|
1. Check the version: `opencode --version`, `opencode api get /api/info`.
|
||||||
|
2. Pick the flavor. Default to Promise. Effect only if the project already uses
|
||||||
|
Effect. TUI is a separate export. RPC is a contract plus a registration.
|
||||||
|
3. Open the source doc in the table above and keep it open.
|
||||||
|
4. Copy the template. Delete the sections you do not need.
|
||||||
|
5. Verify every field name against that page. Do not guess.
|
||||||
|
|
||||||
|
## Rules the templates encode
|
||||||
|
|
||||||
|
These are the constraints the pages state, not stylistic preferences. Note which
|
||||||
|
are type-level rather than documented runtime failures.
|
||||||
|
|
||||||
|
- A `transform` callback is typed `(editor) => void` in both flavors — no
|
||||||
|
Promise, no Effect.
|
||||||
|
- Tool `update` preserves name and namespace. **Assign** a new schema or options
|
||||||
|
object to replace one rather than mutating nested values. In-place edits inside
|
||||||
|
an `update` callback are fine — that is what the mutable draft is for.
|
||||||
|
- `reload()` replays transforms. It does **not** rerun `setup` / `effect`.
|
||||||
|
- Captured inputs are not watched. Load external data before the sync callback,
|
||||||
|
then call `reload()` when it changes.
|
||||||
|
- Use the **effective** tool name — including its namespace — for `update` and
|
||||||
|
`remove` (`example_greeting`, not `greeting`). Only `add` creates a tool.
|
||||||
|
- A `context` hook covers the agent loop only. Register each request kind you
|
||||||
|
actually need.
|
||||||
|
- Result shape is **per operation, not per flavor**: `storage.get` returns a
|
||||||
|
value, `model.list()` is enveloped. Copy the page's example for the call you
|
||||||
|
use.
|
||||||
|
- Effect plugins use `effect`, not `setup`. The two flavors do not have the same
|
||||||
|
context members or the same hook set.
|
||||||
|
- Relative plugin paths in config resolve from the **config file**, not the
|
||||||
|
working directory.
|
||||||
|
- Registering an event subscription without tearing it down leaks it.
|
||||||
|
`forkScoped` handles this in Effect; `AbortController` in Promise.
|
||||||
|
- `package.json` must be strict JSON — `//` comments there break `bun`, `npm`,
|
||||||
|
and every bundler. `opencode.jsonc` may use them.
|
||||||
|
|
||||||
|
## Anything not in a template
|
||||||
|
|
||||||
|
The pages carry more detail than fits here. When you need something not in these
|
||||||
|
files, go to the source doc rather than improvising:
|
||||||
|
|
||||||
|
- Every `Agent.Info`, `Provider.Info`, `Model.Info`, `Session.Info`,
|
||||||
|
`Tool.Content`, `Mcp.Server`, `Skill.Info`, `Vcs.Info`, `Reference.Info`,
|
||||||
|
`Integration.Info`, `Connection.Info`, `Form.Answer`, `Command.Info`,
|
||||||
|
`Plugin.Info`, `WebSearch.*`, `Worktree*` shape:
|
||||||
|
<https://opencode.ai/v2/docs/api>
|
||||||
|
- The exact contract of the running server: `/openapi.json` on that server.
|
||||||
|
- Hook event fields: the `Reference` code block at the end of each section on
|
||||||
|
the relevant page.

# Publishing a plugin package
|
||||||
|
|
||||||
|
`package.json` here is **strict JSON with no comments**, because Node, bun, npm,
|
||||||
|
and every bundler parse it with a strict parser. Copy it as-is and delete the
|
||||||
|
entrypoints you do not implement. Guidance lives in this file rather than in
|
||||||
|
comments inside the manifest.
|
||||||
|
|
||||||
|
Source: <https://opencode.ai/v2/docs/build/plugins> (Publish)
|
||||||
|
|
||||||
|
## Entrypoints
|
||||||
|
|
||||||
|
```json title="package.json"
|
||||||
|
{
|
||||||
|
"name": "opencode-acme-plugin",
|
||||||
|
"version": "1.0.0",
|
||||||
|
"type": "module",
|
||||||
|
"exports": {
|
||||||
|
".": "./src/index.ts",
|
||||||
|
"./rpc": "./src/rpc.ts",
|
||||||
|
"./tui": "./src/tui.tsx"
|
||||||
|
},
|
||||||
|
"dependencies": {
|
||||||
|
"@opencode/plugin": "latest"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
| Export | Needed for | Documented on |
|
||||||
|
| ------ | ---------- | ------------- |
|
||||||
|
| `.` | a server plugin | <https://opencode.ai/v2/docs/build/plugins> |
|
||||||
|
| `./rpc` | publishing a shared RPC contract others can import without loading your implementation. The docs call this export **optional**. | <https://opencode.ai/v2/docs/build/plugins> |
|
||||||
|
| `./tui` | the TUI plugin. Exporting it makes the CLI load the plugin automatically when the package is listed in `opencode.json(c)`. **Do not also add the package to `cli.json`** — the CLI gets the active plugin list from the server. | <https://opencode.ai/v2/docs/build/plugins/cli/> and <https://opencode.ai/v2/docs/cli/plugins> |
|
||||||
|
|
||||||
|
## Effect plugin
|
||||||
|
|
||||||
|
The documented manifest puts `effect` in `peerDependencies`, not
|
||||||
|
`dependencies`:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"dependencies": { "@opencode/plugin": "latest" },
|
||||||
|
"peerDependencies": { "effect": ">=4.0.0-rc.112" }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Do **not** bundle `effect`. OpenCode provides `effect`, `effect/*`, and
|
||||||
|
`@opencode/plugin` at runtime and redirects imports — including from your
|
||||||
|
`node_modules` — to the host instance, so fibers, loggers, and `Schema` parsers
|
||||||
|
share one runtime copy. If you bundle, mark `effect` and `effect/*` external.
|
||||||
|
|
||||||
|
The same Effect page also says to install `effect` and `@opencode/plugin` as
|
||||||
|
peer/dev dependencies for local type-checking:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
bun add --peer @opencode/plugin effect
|
||||||
|
```
|
||||||
|
|
||||||
|
Plugins always execute against the host release's `effect`. Using APIs or module
|
||||||
|
paths from another `effect` major (such as Effect 3) is not supported. Only
|
||||||
|
public `effect` subpaths are provided; importing an `internal` module fails to
|
||||||
|
load with an error naming the path. The compiled OpenCode binary omits the
|
||||||
|
Scalar/Swagger UI assets used by Effect's HTTP API doc pages, so serving those
|
||||||
|
from a plugin shows a notice.
|
||||||
|
|
||||||
|
## TUI plugin rendering JSX
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"peerDependencies": {
|
||||||
|
"@opentui/core": ">=0.5.8",
|
||||||
|
"@opentui/solid": ">=0.5.8",
|
||||||
|
"solid-js": ">=1.9.0"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
From <https://opencode.ai/v2/docs/build/plugins/cli/>. Confirm the version floors
|
||||||
|
against that page before publishing; they are the kind of value that goes stale.
|
||||||
|
|
||||||
|
## Testing before publishing
|
||||||
|
|
||||||
|
Test the **installed** package, not only a workspace-linked copy:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
bun pm pack
|
||||||
|
bun add ./opencode-acme-plugin-1.0.0.tgz
|
||||||
|
```
|
||||||
|
|
||||||
|
Use versions compatible with the OpenCode release you target — check with
|
||||||
|
`opencode --version`. If a release changes the plugin API, publish a compatible
|
||||||
|
update rather than leaving an old contract in place.
