-description: ALWAYS use this when writing docs
-color: "#38A3EE"
----
-
-You are an expert technical documentation writer
-
-You are not verbose
-
-Use a relaxed and friendly tone
-
-The title of the page should be a word or a 2-3 word phrase
-
-The description should be one short line, should not start with "The", should
-avoid repeating the title of the page, should be 5-10 words long
-
-Chunks of text should not be more than 2 sentences long
-
-Each section is separated by a divider of 3 dashes
-
-The section titles are short with only the first letter of the word capitalized
-
-The section titles are in the imperative mood
-
-The section titles should not repeat the term used in the page title, for
-example, if the page title is "Models", avoid using a section title like "Add
-new models". This might be unavoidable in some cases, but try to avoid it.
-
-Check out the /packages/web/src/content/docs/docs/index.mdx as an example.
-
-For JS or TS code snippets remove trailing semicolons and any trailing commas
-that might not be needed.
-
-If you are making a commit prefix the commit message with `docs:`

+
+`util/filesystem.ts` (raw fs wrapper) is used by **64 files**. The effectified `AppFileSystem` service (`filesystem/index.ts`) exists but only has **8 consumers**.

+# TUI plugins
+
+Technical reference for the current TUI plugin system.
+
+## Overview
+
+- TUI plugin config lives in `tui.json`.
+- Author package entrypoint is `@opencode-ai/plugin/tui`.
+- Internal plugins load inside the CLI app the same way external TUI plugins do.
+- Package plugins can be installed from CLI or TUI.
+- v1 plugin modules are target-exclusive: a module can export `server` or `tui`, never both.
+- Server runtime keeps v0 legacy fallback (function exports / enumerated exports) after v1 parsing.
+
+## TUI config
+
+Example:
+
+```json
+{
+  "$schema": "https://opencode.ai/tui.json",
+  "theme": "smoke-theme",
+  "plugin": ["@acme/opencode-plugin@1.2.3", ["./plugins/demo.tsx", { "label": "demo" }]],
+  "plugin_enabled": {
+    "acme.demo": false
+  }
+}
+```
+
+- `plugin` entries can be either a string spec or `[spec, options]`.
+- Plugin specs can be npm specs, `file://` URLs, relative paths, or absolute paths.
+- Relative path specs are resolved relative to the config file that declared them.
+- A file module listed in `tui.json` must be a TUI module (`default export { id?, tui }`) and must not export `server`.
+- Duplicate npm plugins are deduped by package name; higher-precedence config wins.
+- Duplicate file plugins are deduped by exact resolved file spec. This happens while merging config, before plugin modules are loaded.
+- `plugin_enabled` is keyed by plugin id, not by plugin spec.
+- For file plugins, that id must come from the plugin module's exported `id`. For npm plugins, it is the exported `id` or the package name if `id` is omitted.
+- Plugins are enabled by default. `plugin_enabled` is only for explicit overrides, usually to disable a plugin with `false`.
+- `plugin_enabled` is merged across config layers.
+- Runtime enable/disable state is also stored in KV under `plugin_enabled`; that KV state overrides config on startup.
+
+## Author package shape
+
+Package entrypoint:
+
+- Import types from `@opencode-ai/plugin/tui`.
+- `@opencode-ai/plugin` exports `./tui` and declares optional peer deps on `@opentui/core` and `@opentui/solid`.
+
+Minimal module shape:
+
+```tsx
+/** @jsxImportSource @opentui/solid */
+import type { TuiPlugin, TuiPluginModule } from "@opencode-ai/plugin/tui"
+
+const tui: TuiPlugin = async (api, options, meta) => {
+  api.command.register(() => [
+    {
+      title: "Demo",
+      value: "demo.open",
+      onSelect: () => api.route.navigate("demo"),
+    },
+  ])
+
+  api.route.register([
+    {
+      name: "demo",
+      render: () => (
+        <box>
+          <text>demo</text>
+        </box>
+      ),
+    },
+  ])
+}
+
+const plugin: TuiPluginModule & { id: string } = {
+  id: "acme.demo",
+  tui,
+}
+
+export default plugin
+```
+
+- Loader only reads the module default export object. Named exports are ignored.
+- TUI shape is `default export { id?, tui }`; including `server` is rejected.
+- A single module cannot export both `server` and `tui`.
+- `tui` signature is `(api, options, meta) => Promise<void>`.
+- If package `exports` contains `./tui`, the loader resolves that entrypoint. Otherwise it uses the resolved package target.
+- If a package supports both server and TUI, use separate files and package `exports` (`./server` and `./tui`) so each target resolves to a target-only module.
+- File/path plugins must export a non-empty `id`.
+- npm plugins may omit `id`; package `name` is used.
+- Runtime identity is the resolved plugin id. Later plugins with the same id are rejected, including collisions with internal plugin ids.
+- If a path spec points at a directory, that directory must have `package.json` with `main`.
+- There is no directory auto-discovery for TUI plugins; they must be listed in `tui.json`.
+
+## Package manifest and install
+
+Package manifest is read from `package.json` field `oc-plugin`.
+
+Example:
+
+```json
+{
+  "name": "@acme/opencode-plugin",
+  "type": "module",
+  "main": "./dist/index.js",
+  "engines": {
+    "opencode": "^1.0.0"
+  },
+  "oc-plugin": [
+    ["server", { "custom": true }],
+    ["tui", { "compact": true }]
+  ]
+}
+```
+
+### Version compatibility
+
+npm plugins can declare a version compatibility range in `package.json` using the standard `engines` field:
+
+```json
+{
+  "engines": {
+    "opencode": "^1.0.0"
+  }
+}
+```
+
+- The value is a semver range checked against the running OpenCode version.
+- If the range is not satisfied, the plugin is skipped with a warning and a session error.
+- If `engines.opencode` is absent, no check is performed (backward compatible).
+- File plugins are never checked; only npm package plugins are validated.
+
+- Install flow is shared by CLI and TUI in `src/plugin/install.ts`.
+- Shared helpers are `installPlugin`, `readPluginManifest`, and `patchPluginConfig`.
+- `opencode plugin <module>` and TUI install both run install → manifest read → config patch.
+- Alias: `opencode plug <module>`.
+- `-g` / `--global` writes into the global config dir.
+- Local installs resolve target dir inside `patchPluginConfig`.
+- For local scope, path is `<worktree>/.opencode` only when VCS is git and `worktree !== "/"`; otherwise `<directory>/.opencode`.
+- Root-worktree fallback (`worktree === "/"` uses `<directory>/.opencode`) is covered by regression tests.
+- `patchPluginConfig` applies all declared manifest targets (`server` and/or `tui`) in one call.
+- `patchPluginConfig` returns structured result unions (`ok`, `code`, fields by error kind) instead of custom thrown errors.
+- Without `--force`, an already-configured npm package name is a no-op.
+- With `--force`, replacement matches by package name. If the existing row is `[spec, options]`, those tuple options are kept.
+- Tuple targets in `oc-plugin` provide default options written into config.
+- A package can target `server`, `tui`, or both.
+- If a package targets both, each target must still resolve to a separate target-only module. Do not export `{ server, tui }` from one module.
+- There is no uninstall, list, or update CLI command for external plugins.
+- Local file plugins are configured directly in `tui.json`.
+
+When `plugin` entries exist in a writable `.opencode` dir or `OPENCODE_CONFIG_DIR`, OpenCode installs `@opencode-ai/plugin` into that dir and writes:
+
+- `package.json`
+- `bun.lock`
+- `node_modules/`
+- `.gitignore`
+
+That is what makes local config-scoped plugins able to import `@opencode-ai/plugin/tui`.
+
+## TUI plugin API
+
+Top-level API groups exposed to `tui(api, options, meta)`:
+
+- `api.app.version`
+- `api.command.register(cb)` / `api.command.trigger(value)`
+- `api.route.register(routes)` / `api.route.navigate(name, params?)` / `api.route.current`
+- `api.ui.Dialog`, `DialogAlert`, `DialogConfirm`, `DialogPrompt`, `DialogSelect`, `ui.toast`, `ui.dialog`
+- `api.keybind.match`, `print`, `create`
+- `api.tuiConfig`
+- `api.kv.get`, `set`, `ready`
+- `api.state`
+- `api.theme.current`, `selected`, `has`, `set`, `install`, `mode`, `ready`
+- `api.client`, `api.scopedClient(workspaceID?)`, `api.workspace.current()`, `api.workspace.set(workspaceID?)`
+- `api.event.on(type, handler)`
+- `api.renderer`
+- `api.slots.register(plugin)`
+- `api.plugins.list()`, `activate(id)`, `deactivate(id)`, `add(spec)`, `install(spec, options?)`
+- `api.lifecycle.signal`, `api.lifecycle.onDispose(fn)`
+
+### Commands
+
+`api.command.register` returns an unregister function. Command rows support:
+
+- `title`, `value`
+- `description`, `category`
+- `keybind`
+- `suggested`, `hidden`, `enabled`
+- `slash: { name, aliases? }`
+- `onSelect`
+
+Command behavior:
+
+- Registrations are reactive.
+- Later registrations win for duplicate `value` and for keybind handling.
+- Hidden commands are removed from the command dialog and slash list, but still respond to keybinds and `command.trigger(value)` if `enabled !== false`.
+
+### Routes
+
+- Reserved route names: `home` and `session`.
+- Any other name is treated as a plugin route.
+- `api.route.current` returns one of:
+  - `{ name: "home" }`
+  - `{ name: "session", params: { sessionID, initialPrompt? } }`
+  - `{ name: string, params?: Record<string, unknown> }`
+- `api.route.navigate("session", params)` only uses `params.sessionID`. It cannot set `initialPrompt`.
+- If multiple plugins register the same route name, the last registered route wins.
+- Unknown plugin routes render a fallback screen with a `go home` action.
+
+### Dialogs and toast
+
+- `ui.Dialog` is the base dialog wrapper.
+- `ui.DialogAlert`, `ui.DialogConfirm`, `ui.DialogPrompt`, `ui.DialogSelect` are built-in dialog components.
+- `ui.toast(...)` shows a toast.
+- `ui.dialog` exposes the host dialog stack:
+  - `replace(render, onClose?)`
+  - `clear()`
+  - `setSize("medium" | "large" | "xlarge")`
+  - readonly `size`, `depth`, `open`
+
+### Keybinds
+
+- `api.keybind.match(key, evt)` and `print(key)` use the host keybind parser/printer.
+- `api.keybind.create(defaults, overrides?)` builds a plugin-local keybind set.
+- Only missing, blank, or non-string overrides are ignored. Key syntax is not validated.
+- Returned keybind set exposes `all`, `get(name)`, `match(name, evt)`, `print(name)`.
+
+### KV, state, client, events
+
+- `api.kv` is the shared app KV store backed by `state/kv.json`. It is not plugin-namespaced.
+- `api.kv` exposes `ready`.
+- `api.tuiConfig` and `api.state` are live host objects/getters, not frozen snapshots.
+- `api.state` exposes synced TUI state:
+  - `ready`
+  - `config`
+  - `provider`
+  - `path.{state,config,worktree,directory}`
+  - `vcs?.branch`
+  - `workspace.list()` / `workspace.get(workspaceID)`
+  - `session.count()`
+  - `session.diff(sessionID)`
+  - `session.todo(sessionID)`
+  - `session.messages(sessionID)`
+  - `session.status(sessionID)`
+  - `session.permission(sessionID)`
+  - `session.question(sessionID)`
+  - `part(messageID)`
+  - `lsp()`
+  - `mcp()`
+- `api.client` always reflects the current runtime client.
+- `api.scopedClient(workspaceID?)` creates or reuses a client bound to a workspace.
+- `api.workspace.set(...)` rebinds the active workspace; `api.client` follows that rebind.
+- `api.event.on(type, handler)` subscribes to the TUI event stream and returns an unsubscribe function.
+- `api.renderer` exposes the raw `CliRenderer`.
+
+### Theme
+
+- `api.theme.current` exposes the resolved current theme tokens.
+- `api.theme.selected` is the selected theme name.
+- `api.theme.has(name)` checks for an installed theme.
+- `api.theme.set(name)` switches theme and returns `boolean`.
+- `api.theme.mode()` returns `"dark" | "light"`.
+- `api.theme.install(jsonPath)` installs a theme JSON file.
+- `api.theme.ready` reports theme readiness.
+
+Theme install behavior:
+
+- Relative theme paths are resolved from the plugin root.
+- Theme name is the JSON basename.
+- Install is skipped if that theme name already exists.
+- Local plugins persist installed themes under the local `.opencode/themes` area near the plugin config source.
+- Global plugins persist installed themes under the global `themes` dir.
+- Invalid or unreadable theme files are ignored.
+
+### Slots
+
+Current host slot names:
+
+- `app`
+- `home_logo`
+- `home_bottom`
+- `sidebar_title` with props `{ session_id, title, share_url? }`
+- `sidebar_content` with props `{ session_id }`
+- `sidebar_footer` with props `{ session_id }`
+
+Slot notes:
+
+- Slot context currently exposes only `theme`.
+- `api.slots.register(plugin)` returns the host-assigned slot plugin id.
+- `api.slots.register(plugin)` does not return an unregister function.
+- Returned ids are `pluginId`, `pluginId:1`, `pluginId:2`, and so on.
+- Plugin-provided `id` is not allowed.
+- The current host renders `home_logo` with `replace`, `sidebar_title` and `sidebar_footer` with `single_winner`, and `app`, `home_bottom`, and `sidebar_content` with the slot library default mode.
+- Plugins cannot define new slot names in this branch.
+
+### Plugin control and lifecycle
+
+- `api.plugins.list()` returns `{ id, source, spec, target, enabled, active }[]`.
+- `enabled` is the persisted desired state. `active` means the plugin is currently initialized.
+- `api.plugins.activate(id)` sets `enabled=true`, persists it into KV, and initializes the plugin.
+- `api.plugins.deactivate(id)` sets `enabled=false`, persists it into KV, and disposes the plugin scope.
+- `api.plugins.add(spec)` trims the input and returns `false` for an empty string.
+- `api.plugins.add(spec)` treats the input as the runtime plugin spec and loads it without re-reading `tui.json`.
+- `api.plugins.add(spec)` no-ops when that resolved spec (or resolved plugin id) is already loaded.
+- `api.plugins.add(spec)` assumes enabled and always attempts initialization (it does not consult config/KV enable state).
+- `api.plugins.install(spec, { global? })` runs install -> manifest read -> config patch using the same helper flow as CLI install.
+- `api.plugins.install(...)` returns either `{ ok: false, message, missing? }` or `{ ok: true, dir, tui }`.
+- `api.plugins.install(...)` does not load plugins into the current session. Call `api.plugins.add(spec)` to load after install.
+- For packages that declare a tuple `tui` target in `oc-plugin`, `api.plugins.install(...)` stages those tuple options so a following `api.plugins.add(spec)` uses them.
+- If activation fails, the plugin can remain `enabled=true` and `active=false`.
+- `api.lifecycle.signal` is aborted before cleanup runs.
+- `api.lifecycle.onDispose(fn)` registers cleanup and returns an unregister function.
+
+## Plugin metadata
+
+`meta` passed to `tui(api, options, meta)` contains:
+
+- `state`: `first | updated | same`
+- `id`, `source`, `spec`, `target`
+- npm-only fields when available: `requested`, `version`
+- file-only field when available: `modified`
+- `first_time`, `last_time`, `time_changed`, `load_count`, `fingerprint`
+
+Metadata is persisted by plugin id.
+
+- File plugin fingerprint is `target|modified`.
+- npm plugin fingerprint is `target|requested|version`.
+- Internal plugins get synthetic metadata with `state: "same"`.
+
+## Runtime behavior
+
+- Internal TUI plugins load first.
+- External TUI plugins load from `tuiConfig.plugin`.
+- `--pure` / `OPENCODE_PURE` skips external TUI plugins only.
+- External plugin resolution and import are parallel.
+- External plugin activation is sequential to keep command, route, and side-effect order deterministic.
+- File plugins that fail initially are retried once after waiting for config dependency installation.
+- Runtime add uses the same external loader path, including the file-plugin retry after dependency wait.
+- Runtime add skips duplicates by resolved spec and returns `true` when the spec is already loaded.
+- Runtime install and runtime add are separate operations.
+- Plugin init failure rolls back that plugin's tracked registrations and loading continues.
+- TUI runtime tracks and disposes:
+  - command registrations
+  - route registrations
+  - event subscriptions
+  - slot registrations
+  - explicit `lifecycle.onDispose(...)` handlers
+- Cleanup runs in reverse order.
+- Cleanup is awaited.
+- Total cleanup budget per plugin is 5 seconds; timeout/error is logged and shutdown continues.
+
+## Built-in plugins
+
+- `internal:home-tips`
+- `internal:sidebar-context`
+- `internal:sidebar-mcp`
+- `internal:sidebar-lsp`
+- `internal:sidebar-todo`
+- `internal:sidebar-files`
+- `internal:sidebar-footer`
+- `internal:plugin-manager`
+
+Sidebar content order is currently: context `100`, mcp `200`, lsp `300`, todo `400`, files `500`.
+
+The plugin manager is exposed as a command with title `Plugins` and value `plugins.list`.
+
+- Keybind name is `plugin_manager`.
+- Default keybind is `none`.
+- It lists both internal and external plugins.
+- It toggles based on `active`.
+- Its own row is disabled only inside the manager dialog.
+- It also exposes command `plugins.install` with title `Install plugin`.
+- Inside the Plugins dialog, key `shift+i` opens the install prompt.
+- Install prompt asks for npm package name.
+- Scope defaults to local, and `tab` toggles local/global.
+- Install is blocked until `api.state.path.directory` is available; current guard message is `Paths are still syncing. Try again in a moment.`.
+- Manager install uses `api.plugins.install(spec, { global })`.
+- If the installed package has no `tui` target (`tui=false`), manager reports that and does not expect a runtime load.
+- If install reports `tui=true`, manager then calls `api.plugins.add(spec)`.
+- If runtime add fails, TUI shows a warning and restart remains the fallback.
+
+## Current in-repo examples
+
+- Local smoke plugin: `.opencode/plugins/tui-smoke.tsx`
+- Local smoke config: `.opencode/tui.json`
+- Local smoke theme: `.opencode/plugins/smoke-theme.json`
