          },
        },
      ],
    }`

See Configure plugins for more loading and configuration options.

## Lifecycle

`setup` runs when the plugin loads. It may return a cleanup function that runs when the plugin unloads.
    
    `import { Plugin } from &quot;@opencode/plugin&quot;
    
    export default Plugin.define({
      id: &quot;example&quot;,
      setup(ctx) {
        console.log(`loaded in OpenCode ${ctx.app.version}`)
        return () =&gt; console.log(&quot;unloaded&quot;)
      },
    })`

### Context

The plugin context is essentially an OpenCode server client. Its read and action methods use the same inputs and responses as the client. It adds plugin-only methods for transforms, runtime hooks, reloads, registrations, and plugin options.
    
    `setup(ctx) {
      console.log(ctx.app.version)
    }`

`ctx.location` describes the location where this plugin instance is loaded. It includes `directory`, optional `workspaceID`, and `project` metadata (`id`, `directory`, and `canonical`). It is available in both Promise and Effect plugins. This is the plugin instance’s location, not the location of every session it can access or event it receives.
    
    `setup(ctx) {
      console.log(ctx.location.directory)
      console.log(ctx.location.project.canonical)
    }`

### Options

Pass plugin options with the object form in `opencode.json(c)`.

opencode.jsonc
    
    `{
      &quot;plugins&quot;: [
        {
          &quot;package&quot;: &quot;./plugins/company&quot;,
          &quot;options&quot;: {
            &quot;strict&quot;: true,
          },
        },
      ],
    }`

Read those values from `ctx.options` during `setup`.

plugins/company/index.ts
    
    `import { Plugin } from &quot;@opencode/plugin&quot;
    
    export default Plugin.define({
      id: &quot;company&quot;,
      setup(ctx) {
        const strict = ctx.options.strict === true
      },
    })`

## Transforms

Transforms are synchronous edits to OpenCode’s domain state, and each builds on earlier registrations. Registry reads such as `ctx.catalog.model.list()` reflect every registration so far, including during plugin setup; startup batching only coalesces update notifications and never delays what a read returns. ## API

### Agent

Read all agents or fetch one by ID.
    
    `const agents = await ctx.agent.list()
    const build = await ctx.agent.get({ agentID: &quot;build&quot; })`

Register a transform to inspect, update, remove, or select the default agent.
    
    `await ctx.agent.transform((editor) =&gt; {
      const agents = editor.list()
      const build = editor.get(&quot;build&quot;)
    
      editor.default(&quot;build&quot;)
      editor.update(&quot;build&quot;, (agent) =&gt; {
        agent.description = &quot;Builds features and fixes bugs&quot;
      })
      editor.remove(&quot;legacy&quot;)
    })`

Reload agents after external state used by a transform changes.
    
    `await ctx.agent.reload()`

#### Reference

Schema: `Agent.Info`
    
    `interface AgentContext {
      list(input?: AgentListInput, requestOptions?: RequestOptions): Promise&lt;AgentListOutput&gt;
      get(input: AgentGetInput, requestOptions?: RequestOptions): Promise&lt;AgentGetOutput&gt;
      transform(callback: (editor: AgentEditor) =&gt; void): Promise&lt;Registration&gt;
      reload(): Promise&lt;void&gt;
### Plugins

List the plugins currently active for a location.
    
    `const plugins = await ctx.plugin.list()`

#### Reference

Schemas: `Plugin.Info`, `Plugin.Source`
    
    `interface PluginContext {
      list(input?: PluginListInput, requestOptions?: RequestOptions): Promise&lt;PluginListOutput&gt;
    }`

### References

Read the references available at a location.
    
    `const references = await ctx.reference.list()`

Register a transform to inspect, add, or remove local and Git references. `get(name)` returns the current configured source, or `undefined` when the name is absent.
    
    `await ctx.reference.transform((editor) =&gt; {
      const references = editor.list()
      editor.add(&quot;handbook&quot;, { type: &quot;local&quot;, path: &quot;/workspace/docs/handbook&quot; })
      editor.add(&quot;standards&quot;, { type: &quot;git&quot;, repository: &quot;https://github.com/acme/standards&quot;, branch: &quot;main&quot; })
      const handbook = editor.get(&quot;handbook&quot;)
      editor.remove(&quot;legacy&quot;)
    })`

Reload references after external state used by a transform changes.
### Tools

Register, update, and remove tools with a synchronous transform, including in Promise plugins. Load external data before registering or reloading. A later valid registration overrides the same effective tool name.
    
    `const registration = await ctx.tool.transform((editor) =&gt; {
      editor.namespace({
        name: &quot;acme&quot;,
        description: &quot;Customer account tools&quot;,
      })
      editor.add({
        name: &quot;greeting&quot;,
        description: &quot;Create a greeting&quot;,
        input: {
          type: &quot;object&quot;,
          properties: { name: { type: &quot;string&quot; } },
          required: [&quot;name&quot;],
          additionalProperties: false,
        },
        options: { namespace: &quot;acme&quot;, codemode: true },
        execute: async (input, tool) =&gt; {
          await tool.progress({ status: &quot;greeting&quot; })
          return { content: `Hello ${(input as { name: string }).name}!` }
        },
      })
    })`

Call `reload()` after changing source data captured by the callback. Reload replays the active transforms without changing their order; it does not rerun plugin setup.
    
    `await ctx.tool.reload()`

Use `list()` and `get()` to inspect tools currently in the editor. Tools have an `id` containing their effective name, and `get()` returns `undefined` when that ID is not present. Use `update` and `remove` with the effective tool name, including its namespace (`acme_greeting` above). Dots in namespaces and unsupported characters in tool names become `_`. Missing names are ignored; creating a tool requires `add` with a complete definition. Updates preserve the name and namespace. Assign new schemas or options to replace them rather than mutating nested values. Invalid updates are logged and leave the previous definition intact.
    
    `await ctx.tool.transform((editor) =&gt; {
      editor.update(&quot;acme_greeting&quot;, (tool) =&gt; {
        tool.description = &quot;Greet the user by name&quot;
      })
      editor.remove(&quot;acme_obsolete&quot;)
    })`

Updates and removals replay in order with additions, including after MCP catalog refreshes. Disposing their registration removes those changes and rebuilds from the remaining transforms.

Dispose a registration to remove its transform and rebuild from the remaining transforms, revealing any earlier definition it overrode. Disposal is idempotent, and unloading the plugin also disposes its registrations.
    
    `await registration.dispose()`

Each model request captures a stable, executable tool snapshot. Later transforms, reloads, and disposal affect future snapshots, not the definitions, Code Mode namespace descriptions, or executors already captured. Executors that close over mutable plugin data still observe that data; capture a value inside the transform when it must remain tied to that definition.

#### Reference

Schemas: `Tool.Content`, `Tool.TextContent`, `Tool.FileContent`
    
    `interface ToolContext {
      transform(callback: (editor: ToolEditor) =&gt; void): Promise&lt;Registration&gt;
      reload(): Promise&lt;void&gt;
    }
    
    interface ToolEditor {
      list(): readonly (ToolInfo &amp; { readonly id: string })[]
      get(id: string): (ToolInfo &amp; { readonly id: string }) | undefined
      namespace(namespace: { name: string; description: string }): void
      add(tool: ToolInfo): void
      update(id: string, update: (tool: Types.Mutable&lt;ToolInfo&gt;) =&gt; void): void
      remove(id: string): void
    }`


Both hooks run for every request a session issues. `event.kind` says which flow issued it: `&quot;primary&quot;` for the agent loop, `&quot;compaction&quot;` for checkpoint summaries, `&quot;title&quot;` for title generation, and `&quot;generate&quot;` for transient `ctx.session.generate` calls. Use it instead of the agent ID to tell auxiliary requests apart.
    
    `await ctx.session.hook(&quot;http.request&quot;, (event) =&gt; {
      event.request.headers.set(&quot;x-session-id&quot;, event.sessionID)
      if (event.kind === &quot;title&quot;) event.request.headers.set(&quot;x-priority&quot;, &quot;background&quot;)
    })
    
    await ctx.session.hook(&quot;http.response&quot;, (event) =&gt; {
      event.response = new Response(event.response.body, {
        status: event.response.status,
        headers: { ...Object.fromEntries(event.response.headers), &quot;x-plugin&quot;: &quot;review&quot; },
      })
    })`

#### Retry policy

Override the retry decision for a provider failure or replace its delay in milliseconds. The hook runs after OpenCode classifies the failure and proposes its policy, but before any retry is scheduled. It does not expose how OpenCode internally performs the next attempt.
    
    `await ctx.session.hook(&quot;retry&quot;, (event) =&gt; {
      if (event.error.status === 429) {
        event.decision = { retry: true, delay: 10_000 }
        return
      }
      if (event.error.type === &quot;provider.invalid-request&quot; &amp;&amp; event.attempt === 2) {
        event.decision = { retry: true, delay: 0 }
        return
      }
      if (event.attempt &gt;= 3) event.decision = { retry: false }
    })`

Retry hooks can change OpenCode’s initial `decision` by making a terminal failure retryable or vetoing a proposed retry.

Retry decisions follow these rules:

  * Multiple hooks run in registration order, and later hooks see the current decision.
  * The built-in maximum attempt count remains a hard limit.
  * `attempt` is the physical attempt under consideration. The initial request is `1`, so the first retry is `2`.
  * Invalid delays such as `NaN`, infinity, or negative values fall back to the computed delay.
  * Context-overflow recovery is separate because it compacts the conversation instead of retrying the same request.

#### Session reference
    
    `import type { SessionPrompt } from &quot;@opencode/plugin/promise/session&quot;
    
    interface SessionHooks {
      prompt: SessionPrompt
      context: SessionContextHook
      compaction: SessionContextHook &amp; { result?: SessionCompactionResult }
      generate: SessionContextHook
      title: SessionRequestHook &amp; { result?: string }
      &quot;model.request&quot;: SessionModelRequestHook
      &quot;http.request&quot;: SessionHttpRequestHook
      &quot;http.response&quot;: SessionHttpResponseHook
      retry: SessionRetryHook
    }
    
    type RetryDecision = { retry: false } | { retry: true; delay: number }
    
    interface SessionRetryHook {
      readonly sessionID: string
      readonly agent: string
      readonly model: { providerID: string; id: string; variant?: string }
      readonly error: { type: string; message: string; status?: number }
      readonly attempt: number
      decision: RetryDecision
    }
    
    interface SessionRequestHook {
      readonly sessionID: string
      readonly model: { providerID: string; id: string; variant?: string }

<excerpt>citeturn0search1 [wordlim: 200] Crawled: today;     import { type Plugin, tool } from &quot;@opencode-ai/plugin&quot;

### Custom tools

Plugins can also add custom tools to opencode:

.opencode/plugins/custom-tools.ts
    
    `
    
    import { type Plugin, tool } from &quot;@opencode-ai/plugin&quot;
    
    
    
    
    export const CustomToolsPlugin: Plugin = async (ctx) =&gt; {
    
      return {
    
        tool: {
    
          mytool: tool({
    
            description: &quot;This is a custom tool&quot;,
    
            args: {
    
              foo: tool.schema.string(),
    
            },
    
            async execute(args, context) {
    
              const { directory, worktree } = context
    
              return `Hello ${args.foo} from ${directory} (worktree: ${worktree})`
    
            },
    
          }),
    
        },
    
      }
    
    }
    
    `

The `tool` helper creates a custom tool that opencode can call. It takes a Zod schema function and returns a tool definition with:

  * `description`: What the tool does
  * `args`: Zod schema for the tool’s arguments
  * `execute`: Function that runs when the tool is called

Your custom tools will be available to opencode alongside built-in tools.

Note

If a plugin tool uses the same name as a built-in tool, the plugin tool takes precedence.

### Logging

Use `client.app.log()` instead of `console.log` for structured logging:

.opencode/plugins/my-plugin.ts
    
    `
    
    export const MyPlugin = async ({ client }) =&gt; {
    
      await client.app.log({
    
        body: {
    
          service: &quot;my-plugin&quot;,
    
          level: &quot;info&quot;,
    
          message: &quot;Plugin initialized&quot;,
    
          extra: { foo: &quot;bar&quot; },
    
        },
    
      })
    
    }
    
    `

Levels: `debug`, `info`, `warn`, `error`. See SDK documentation for details.

### Compaction hooks

Customize the context included when a session is compacted:

.opencode/plugins/compaction.ts
    
    `
    
    import type { Plugin } from &quot;@opencode-ai/plugin&quot;
    
    
    
    
    export const CompactionPlugin: Plugin = async (ctx) =&gt; {
    
      return {

<title>Migrate plugins from V1 | OpenCode</title>
<location>https://dev.opencode.ai/v2/docs/build/plugins/migrate-v1</location>
<excerpt>citeturn0search2 [wordlim: 200] Crawled: yesterday; Register a command with `ctx.command.transform` when the plugin owns that command. ...     `import { tool } from &quot;@opencode-ai/plugin&quot;
            throw new Error(&quot;Do not read .env files&quot;)
          }
        })
    
        await ctx.shell.hook(&quot;create.before&quot;, (event) =&gt; {
          event.env.COMPANY_ENV = &quot;development&quot;
        })
      },
    })`

Registrations stay active for the plugin’s lifetime and are disposed when it unloads. Retain the returned registration only when the plugin needs to remove that particular hook or transform earlier with `registration.dispose()`.

Use this table to find the closest V2 API for each V1 hook:

V1 hook  | V2 API
--- | ---
`event`  | `ctx.event.subscribe()`
`dispose`  | cleanup function returned by `setup`
`config`  | transforms on the affected domains
`tool` map  | `ctx.tool.transform(...)`
`auth`  | `ctx.integration.transform(...)` and integration APIs
`provider`  | `ctx.provider.transform(...)` and `ctx.model.transform(...)`
`chat.message`  | `ctx.session.hook(&quot;prompt&quot;, ...)`
`chat.params`  | `ctx.session.hook(&quot;context&quot;, ...)`
`chat.headers`  | `ctx.session.hook(&quot;model.request&quot;, ...)` or `&quot;http.request&quot;`
`permission.ask`  | `ctx.permission.hook(&quot;evaluate&quot;, ...)`
`command.execute.before`  | command transforms or the prompt hook, depending on intent
`tool.execute.before`  | `ctx.tool.hook(&quot;execute.before&quot;, ...)`
`tool.execute.after`  | `ctx.tool.hook(&quot;execute.after&quot;, ...)`
`shell.env`  | `ctx.shell.hook(&quot;create.before&quot;, ...)`
`tool.definition`  | `ctx.tool.transform(...)`
`experimental.chat.system.transform`  | `ctx.session.hook(&quot;context&quot;, ...)` and edit `event.system`
`experimental.chat.messages.transform`  | `ctx.session.hook(&quot;context&quot;, ...)` and edit `event.messages`
`experimental.session.compacting`  | `ctx.session.hook(&quot;compaction&quot;, ...)`

These are migration destinations, not always exact renames. In particular, the V2 `prompt` hook runs before durable prompt admission, while `context` runs immediately before an agent model request. Register `context`, `compaction`, `generate`, and `title` separately if a transformation must apply to every model request kind.

There is no direct V2 hook corresponding to every experimental V1 hook. Re-evaluate plugins that use `experimental.compaction.autocontinue`, `experimental.provider.small_model`, or `experimental.text.complete` against the V2 session, provider, model, and event APIs rather than preserving an internal lifecycle assumption.

`command.execute.before` also has no one-to-one global hook. Register a command with `ctx.command.transform` when the plugin owns that command. Use the prompt hook when the real intent is to modify prompts submitted by commands and other prompt sources.
        })
    
        await ctx.session.hook(&quot;model.request&quot;, (event) =&gt; {
          event.headers[&quot;x-plugin&quot;] = &quot;review&quot;
        })
      },
    })`

Use semantic provider options in `event.options`. Use `model.request` for model request headers and raw request settings, and use `http.request` or `http.response` only when the plugin needs the native provider HTTP exchange. Provider-specific hooks can pass `{ providerID: &quot;...&quot; }` as the third argument to `ctx.session.hook`.

## Migrate custom tools

V1 returns a `tool` map built with the old `tool()` helper. V2 registers tool definitions through a synchronous `ctx.tool.transform` editor. Tool schemas use JSON Schema, and execution returns structured content.

V1
    
    `import { tool } from &quot;@opencode-ai/plugin&quot;
    
    export const ToolsPlugin = async () =&gt; ({
      tool: {
        greeting: tool({
          description: &quot;Create a greeting&quot;,
          args: { name: tool.schema.string() },
          async execute(args) {
            return `Hello ${args.name}!`
          },
        }),
      },
    })`

V2
    
    `import { Plugin } from &quot;@opencode/plugin&quot;
    
    export default Plugin.define({
      id: &quot;greeting&quot;,
      async setup(ctx) {
        await ctx.tool.transform((editor) =&gt; {
          editor.add({
            name: &quot;greeting&quot;,
            description: &quot;Create a greeting&quot;,
            input: {
              type: &quot;object&quot;,
              properties: { name: { type: &quot;string&quot; } },
              required: [&quot;name&quot;],
              additionalProperties: false,
            },
            async execute(input) {
              return { content: `Hello ${(input as { name: string }).name}!` }
            },
          })
        })
      },
    })`

Transforms are replayable state edits. Keep their callback synchronous, cheap, and free of one-time side effects. Load external data before registration, capture it in the callback, and call the domain’s `reload()` method when that data changes. A later plugin transform sees earlier changes and may update, replace, or remove them.

The same transform pattern replaces V1 `config` and `provider` hooks, but V2 does not expose one mutable global config object. Register the change with the domain that owns it: `ctx.agent`, `ctx.provider`, `ctx.model`, `ctx.command`, `ctx.integration`, `ctx.mcp`, `ctx.reference`, `ctx.skill`, `ctx.tool`, `ctx.vcs`, `ctx.websearch`, or `ctx.worktree`. Authentication methods belong to integrations; provider transforms contribute source definitions and provider settings, while model transforms apply restrictions and overrides to the complete active-provider model collection.
    
    `await ctx.provider.transform((editor) =&gt; {
      editor.update(&quot;anthropic&quot;, (provider) =&gt; {
        provider.headers = { ...provider.headers, &quot;x-company&quot;: &quot;engineering&quot; }
      })
    })
    
    await ctx.model.transform((editor) =&gt; {
      editor.list(&quot;anthropic&quot;).forEach((model) =&gt; {
        if (!model.capabilities.tools) editor.remove(model.providerID, model.id)
      })
    })`

This tool is only available when `OPENCODE_EXPERIMENTAL_LSP_TOOL=true` (or `OPENCODE_EXPERIMENTAL=true`). ...

# Tools

Manage the tools an LLM can use.

Tools allow the LLM to perform actions in your codebase. OpenCode comes with a set of built-in tools, but you can extend it with custom tools or MCP servers.

By default, all tools are enabled and don’t need permission to run. You can control tool behavior through permissions.

## Configure

Use the `permission` field to control tool behavior. You can allow, deny, or require approval for each tool.

opencode.json
    
    `
    
    {
    
      &quot;$schema&quot;: &quot;https://opencode.ai/config.json&quot;,
    
      &quot;permission&quot;: {
    
        &quot;edit&quot;: &quot;deny&quot;,
    
        &quot;bash&quot;: &quot;ask&quot;,
    
        &quot;webfetch&quot;: &quot;allow&quot;
    
      }
    
    }
    
    `

You can also use wildcards to control multiple tools at once. For example, to require approval for all tools from an MCP server:

opencode.json
    
    `
    
    {
    
      &quot;$schema&quot;: &quot;https://opencode.ai/config.json&quot;,
    
      &quot;permission&quot;: {
    
        &quot;mymcp_*&quot;: &quot;ask&quot;
    
      }
    
    }
    
    `

Learn more about configuring permissions.

## Built-in

Here are all the built-in tools available in OpenCode.

Execute shell commands in your project environment.

opencode.json
    
    `
    
    {
    
      &quot;$schema&quot;: &quot;https://opencode.ai/config.json&quot;,
    
      &quot;permission&quot;: {
    
        &quot;bash&quot;: &quot;allow&quot;
    
      }
    
    }
    
    `

This tool allows the LLM to run terminal commands like `npm install`, `git status`, or any other shell command.

Denying `execute` with resource `*` removes Code Mode and every tool reached only through it, including MCP tools from servers that do not set `codemode: false`. Nested built-in and MCP tools still enforce their own permissions, and plugin tools enforce the permissions they assert.

The ID must be in the advertised skill list or explicitly named by the user. Permission: `skill` with the skill ID as its resource. See Skills for creation, discovery, and loading rules.

## Automation

### Subagent

`subagent` starts a child session with a configured subagent. Supply the agent ID, a short `description`, and a complete `prompt`.
    
    `Ask the explore subagent to map the authentication flow and return the key files.`

Foreground calls wait for the result. `background: true` returns immediately and notifies the parent when the child finishes. Pass the returned `sessionID` to continue that same child conversation. Only subagent-mode agents can be used, and the default nesting depth is one.

Permission: `subagent` with the selected agent ID as its resource.

### Execute

`execute` runs JavaScript in Code Mode so the agent can call and combine tools from the catalog. It is useful for parallel independent calls and for processing results without adding every intermediate value to the model context.
    
    `Read package.json and README.md in parallel, then return their relevant setup details.`

The runtime has no direct filesystem access, imports, or timers. It provides `fetch` for HTTP requests; everything else goes through tools in its catalog. Denying `execute` with resource `*` removes Code Mode and every tool reached only through it, including MCP tools from servers that do not set `codemode: false`. Nested built-in and MCP tools still enforce their own permissions, and plugin tools enforce the permissions they assert.

Update the registerTools rejection handler in the plugin setup flow to report
the registration error through the host logging API instead of silently
swallowing it. Preserve the existing non-aborting setup behavior and session
hooks.

Update forget in the viaDaemon error path to clear missedAt when invalidating a

honoring the discovery cooldown.

Update annotation handling in annotation() so viaCLI binary-produced results are
not labeled as answered by the chosen daemon; append this annotation only to
responses known to come from that daemon, or use wording that does not claim
which daemon answered.

Update applyChoice so session-scoped daemon choices are stored by sessionID
rather than in the runtime-wide chosen and found state. Pass sessionID through
look(), daemon(), and the tool executors, and use it to retrieve the correct
session’s choice so one session cannot route through another session’s daemon.

Update the daemon_select schema and execute input to use the candidate’s
