  - You want to create a new Nodmix plugin
  - You need a quick-start for plugin development
  - You are choosing between channel, provider, CLI backend, tool, or hook docs
---

Plugins extend Nodmix without changing core. A plugin can add a messaging
channel, model provider, local CLI backend, agent tool, hook, media provider,
or another plugin-owned capability.

You do not need to add an external plugin to the Nodmix repository. Publish
the package to [skills.nodmix.com](/clawhub) and users install it with:

```bash
nodmix plugins install clawhub:<package-name>
```

Bare package specs still install from npm during the launch cutover. Use the
`clawhub:` prefix when you want skills.nodmix.com resolution.

## Requirements

- Use Node 22.19 or newer and a package manager such as `npm` or `pnpm`.
- Be familiar with TypeScript ESM modules.
- For in-repo bundled plugin work, clone the repository and run `pnpm install`.
  Source-checkout plugin development is pnpm-only because Nodmix loads bundled
  plugins from `extensions/*` workspace packages.

## Quickstart

Build a minimal tool plugin by registering one required agent tool. This is the
shortest useful plugin shape and shows the package, manifest, entry point, and
local proof.

<Steps>
  <Step title="Create package metadata">
    <CodeGroup>

```json package.json
{
  "name": "@myorg/nodmix-my-plugin",
  "version": "1.0.0",
  "type": "module",
  "nodmix": {
    "extensions": ["./index.ts"],
    "compat": {
      "pluginApi": ">=2026.3.24-beta.2",
      "minGatewayVersion": "2026.3.24-beta.2"
    },
    "build": {
      "nodmixVersion": "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 Nodmix",
  "contracts": {
    "tools": ["my_tool"]
  },
  "activation": {
    "onStartup": true
  },
  "configSchema": {
    "type": "object",
    "additionalProperties": false
  }
}
```

    </CodeGroup>

    Published external plugins should point runtime entries at built JavaScript
    files. See [SDK entry points](/plugins/sdk-entrypoints) for the full entry
    point contract.

    Every plugin needs a manifest, even when it has no config. Runtime tools
    must appear in `contracts.tools` so Nodmix can discover ownership without
    eagerly loading every plugin runtime. Set `activation.onStartup`
    intentionally. This example starts on Gateway startup.

    For every manifest field, see [Plugin manifest](/plugins/manifest).

  </Step>

  <Step title="Register the tool">
    ```typescript index.ts
    import { Type } from "typebox";
    import { definePluginEntry } from "nodmix/plugin-sdk/plugin-entry";

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

    Use `definePluginEntry` for non-channel plugins. Channel plugins use
    `defineChannelPluginEntry`.

  </Step>

  <Step title="Test the runtime">
    For an installed or external plugin, inspect the loaded runtime:

    ```bash
    nodmix plugins inspect my-plugin --runtime --json
    ```

    If the plugin registers a CLI command, run that command too. For example,
    a demo command should have an execution proof such as
    `nodmix demo-plugin ping`.

    For a bundled plugin in this repository, Nodmix discovers source-checkout
    plugin packages from the `extensions/*` workspace. Run the closest targeted
    test:

    ```bash
    pnpm test -- extensions/my-plugin/
    pnpm check
    ```

  </Step>

  <Step title="Publish">
    Validate the package before publishing:

    ```bash
    clawhub package publish your-org/your-plugin --dry-run
    clawhub package publish your-org/your-plugin
    ```

    The canonical skills.nodmix.com snippets live in `docs/snippets/plugin-publish/`.

  </Step>

  <Step title="Install">
    Install the published package through skills.nodmix.com:

    ```bash
    nodmix plugins install clawhub:your-org/your-plugin
    ```

  </Step>
</Steps>

## Registering tools

Tools can be required or optional. Required tools are always available when the
plugin is enabled. Optional tools require user opt-in.

```typescript
register(api) {
  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 },
  );
}
```

Every tool registered with `api.registerTool(...)` must also be declared in the
plugin manifest:

```json
{
  "contracts": {
    "tools": ["workflow_tool"]
  },
  "toolMetadata": {
    "workflow_tool": {
      "optional": true
    }
  }
}
```

Users opt in with `tools.allow`:

```json5
{
  tools: { allow: ["workflow_tool"] }, // or ["my-plugin"] for all tools from one plugin
}
```

Optional tools control whether a tool is exposed to the model. Use
[plugin permission requests](/plugins/plugin-permission-requests) when a tool
or hook should ask for approval after the model selects it and before the
action runs.

Use optional tools for side effects, unusual binaries, or capabilities that
should not be exposed by default. Tool names must not conflict with core tools;
conflicts are skipped and reported in plugin diagnostics. Malformed
registrations, including tool descriptors without `parameters`, are skipped and
reported the same way. Registered tools are typed functions the model can call
after policy and allowlist checks pass.

Tool factories receive a runtime-supplied context object. Use `ctx.activeModel`
when a tool needs to log, display, or adapt to the active model for the current
turn. The object can include `provider`, `modelId`, and `modelRef`. Treat it as
informational runtime metadata, not as a security boundary against the local
operator, installed plugin code, or a modified Nodmix runtime. Sensitive local
tools should still require an explicit plugin or operator opt-in and fail closed
when active-model metadata is missing or unsuitable.

The manifest declares ownership and discovery; execution still calls the live
registered tool implementation. Keep `toolMetadata.<tool>.optional: true`
aligned with `api.registerTool(..., { optional: true })` so Nodmix can avoid
loading that plugin runtime until the tool is explicitly allowlisted.

## Import conventions

Import from focused SDK subpaths:

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

Do not import from the deprecated root barrel:

```typescript
import { definePluginEntry } from "nodmix/plugin-sdk";
```

Within your plugin package, use local barrel files such as `api.ts` and
`runtime-api.ts` for internal imports. Do not import your own plugin through an
SDK path. Provider-specific helpers should stay in the provider package unless
the seam is truly generic.

Custom Gateway RPC methods are an advanced entry point. Keep them on a
plugin-specific prefix; core admin namespaces such as `config.*`,
`exec.approvals.*`, `operator.admin.*`, `wizard.*`, and `update.*` stay reserved
and resolve to `operator.admin`. The
`nodmix/plugin-sdk/gateway-method-runtime` bridge is reserved for plugin HTTP
routes that declare `contracts.gatewayMethodDispatch: ["authenticated-request"]`.

For the full import map, see [Plugin SDK overview](/plugins/sdk-overview).

## Pre-submission checklist

<Check>**package.json** has correct `nodmix` 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>

## Test against beta releases

1. Watch for GitHub release tags on [nodmix/nodmix](https://github.com/nodmix/nodmix/releases) and subscribe via `Watch` > `Releases`. Beta tags look like `v2026.3.N-beta.1`. You can also turn on notifications for the official Nodmix X account [@nodmix](https://x.com/nodmix) 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.
