# Building Plugins

Plugins extend OpenClaw with new capabilities: channels, model providers, speech,
image generation, web search, agent tools, or any combination.

You do not need to add your plugin to the OpenClaw repository. Publish to
[ClawHub](/tools/clawhub) or npm and users install with
`openclaw plugins install <package-name>`. OpenClaw tries ClawHub first and
falls back to npm automatically.

## Prerequisites

- Node >= 22 and a package manager (npm or pnpm)
- Familiarity with TypeScript (ESM)
- For in-repo plugins: repository cloned and `pnpm install` done

## Quick start: tool plugin

This walkthrough creates a minimal plugin that registers an agent tool. Channel
and provider plugins have dedicated guides linked above.

<Steps>
  <Step title="Create the package and manifest">
    <CodeGroup>
    ```json package.json
    {
      "name": "@myorg/openclaw-my-plugin",
      "version": "1.0.0",
      "type": "module",
      "openclaw": {
        "extensions": ["./index.ts"],
        "compat": {
          "pluginApi": ">=2026.3.24-beta.2",
          "minGatewayVersion": "2026.3.24-beta.2"
        },
        "build": {
          "openclawVersion": "2026.3.24-beta.2",
          "pluginSdkVersion": "2026.3.24-beta.2"
        }
      }
    }
    ```

    ```json openclaw.plugin.json
    {
      "id": "my-plugin",
      "name": "My Plugin",
      "description": "Adds a custom tool to OpenClaw",
      "configSchema": {
        "type": "object",
        "additionalProperties": false
      }
    }
    ```
    </CodeGroup>

    Every plugin needs a manifest, even with no config. See
    [Manifest](/plugins/manifest) for the full schema. The canonical ClawHub
    publish snippets live in `docs/snippets/plugin-publish/`.

  </Step>

  <Step title="Write the entry point">

    ```typescript
    // index.ts
    import { definePluginEntry } from "openclaw/plugin-sdk/plugin-entry";
    import { Type } from "@sinclair/typebox";

    export default definePluginEntry({
      id: "my-plugin",
      name: "My Plugin",
      description: "Adds a custom tool to OpenClaw",
      register(api) {
        api.registerTool({
          name: "my_tool",
          description: "Do a thing",
          parameters: Type.Object({ input: Type.String() }),
          async execute(_id, params) {
            return { content: [{ type: "text", text: `Got: ${params.input}` }] };
          },
        });
      },
    });
    ```

    `definePluginEntry` is for non-channel plugins. For channels, use
    `defineChannelPluginEntry` — see [Channel Plugins](/plugins/sdk-channel-plugins).
    For full entry point options, see [Entry Points](/plugins/sdk-entrypoints).

  </Step>

  <Step title="Test and publish">

    **External plugins:** validate and publish with ClawHub, then install:

    ```bash
    clawhub package publish your-org/your-plugin --dry-run
    clawhub package publish your-org/your-plugin
    openclaw plugins install clawhub:@myorg/openclaw-my-plugin
    ```

    OpenClaw also checks ClawHub before npm for bare package specs like
    `@myorg/openclaw-my-plugin`.

    **In-repo plugins:** place under the bundled plugin workspace tree — automatically discovered.

    ```bash
    pnpm test -- <bundled-plugin-root>/my-plugin/
    ```

  </Step>
</Steps>

## Plugin capabilities

A single plugin can register any number of capabilities via the `api` object:

| Capability            | Registration method                           | Detailed guide                                                                  |

For the full registration API, see [SDK Overview](/plugins/sdk-overview#registration-api).

Hook guard semantics to keep in mind:

- `before_tool_call`: `{ block: true }` is terminal and stops lower-priority handlers.
- `before_tool_call`: `{ block: false }` is treated as no decision.
- `before_tool_call`: `{ requireApproval: true }` pauses agent execution and prompts the user for approval via the exec approval overlay, Telegram buttons, Discord interactions, or the `/approve` command on any channel.
- `before_install`: `{ block: true }` is terminal and stops lower-priority handlers.
- `before_install`: `{ block: false }` is treated as no decision.
- `message_sending`: `{ cancel: true }` is terminal and stops lower-priority handlers.
- `message_sending`: `{ cancel: false }` is treated as no decision.

The `/approve` command handles both exec and plugin approvals with automatic fallback. Plugin approval forwarding can be configured independently via `approvals.plugin` in config.

See [SDK Overview hook decision semantics](/plugins/sdk-overview#hook-decision-semantics) for details.

## Registering agent tools

Tools are typed functions the LLM can call. They can be required (always
available) or optional (user opt-in):

```typescript
register(api) {
  // Required tool — always available
  api.registerTool({
    name: "my_tool",
    description: "Do a thing",
    parameters: Type.Object({ input: Type.String() }),
    async execute(_id, params) {
      return { content: [{ type: "text", text: params.input }] };
    },
  });

  // Optional tool — user must add to allowlist
  api.registerTool(
    {
      name: "workflow_tool",
      description: "Run a workflow",
      parameters: Type.Object({ pipeline: Type.String() }),
      async execute(_id, params) {
        return { content: [{ type: "text", text: params.pipeline }] };
      },
    },
    { optional: true },
  );
}
```

Users enable optional tools in config:

```json5
{
  tools: { allow: ["workflow_tool"] },
}
```

- Tool names must not clash with core tools (conflicts are skipped)
- Use `optional: true` for tools with side effects or extra binary requirements
- Users can enable all tools from a plugin by adding the plugin id to `tools.allow`

## Import conventions

Always import from focused `openclaw/plugin-sdk/<subpath>` paths:

```typescript
import { definePluginEntry } from "openclaw/plugin-sdk/plugin-entry";
import { createPluginRuntimeStore } from "openclaw/plugin-sdk/runtime-store";

// Wrong: monolithic root (deprecated, will be removed)
import { ... } from "openclaw/plugin-sdk";
```

For the full subpath reference, see [SDK Overview](/plugins/sdk-overview).

Within your plugin, use local barrel files (`api.ts`, `runtime-api.ts`) for
internal imports — never import your own plugin through its SDK path.

## Pre-submission checklist

<Check>**package.json** has correct `openclaw` metadata</Check>
<Check>**openclaw.plugin.json** manifest is present and valid</Check>
<Check>Entry point uses `defineChannelPluginEntry` or `definePluginEntry`</Check>
<Check>All imports use focused `plugin-sdk/<subpath>` paths</Check>
<Check>Internal imports use local modules, not SDK self-imports</Check>
<Check>Tests pass (`pnpm test -- <bundled-plugin-root>/my-plugin/`)</Check>
<Check>`pnpm check` passes (in-repo plugins)</Check>

## Beta Release Testing

1. Watch for GitHub release tags on [openclaw/openclaw](https://github.com/openclaw/openclaw/releases) and subscribe via `Watch` > `Releases`. Beta tags look like `v2026.3.N-beta.1`. You can also turn on notifications for the official OpenClaw X account [@openclaw](https://x.com/openclaw) for release announcements.
2. Test your plugin against the beta tag as soon as it appears. The window before stable is typically only a few hours.
3. Post in your plugin's thread in the `plugin-forum` Discord channel after testing with either `all good` or what broke. If you do not have a thread yet, create one.
4. If something breaks, open or update an issue titled `Beta blocker: <plugin-name> - <summary>` and apply the `beta-blocker` label. Put the issue link in your thread.
5. Open a PR to `main` titled `fix(<plugin-id>): beta blocker - <summary>` and link the issue in both the PR and your Discord thread. Contributors cannot label PRs, so the title is the PR-side signal for maintainers and automation. Blockers with a PR get merged; blockers without one might ship anyway. Maintainers watch these threads during beta testing.
6. Silence means green. If you miss the window, your fix likely lands in the next cycle.
