# Plugin SDK Overview

The plugin SDK is the typed contract between plugins and core. This page is the
reference for **what to import** and **what you can register**.

<Tip>
  **Looking for a how-to guide?**
  - First plugin? Start with [Getting Started](/plugins/building-plugins)
  - Channel plugin? See [Channel Plugins](/plugins/sdk-channel-plugins)
  - Provider plugin? See [Provider Plugins](/plugins/sdk-provider-plugins)
</Tip>

## Import convention

Always import from a specific subpath:

```typescript
import { definePluginEntry } from "openclaw/plugin-sdk/plugin-entry";
import { defineChannelPluginEntry } from "openclaw/plugin-sdk/channel-core";
```

Each subpath is a small, self-contained module. This keeps startup fast and
prevents circular dependency issues. For channel-specific entry/build helpers,
prefer `openclaw/plugin-sdk/channel-core`; keep `openclaw/plugin-sdk/core` for
the broader umbrella surface and shared helpers such as
`buildChannelConfigSchema`.

Do not add or depend on provider-named convenience seams such as
`openclaw/plugin-sdk/slack`, `openclaw/plugin-sdk/discord`,
`openclaw/plugin-sdk/signal`, `openclaw/plugin-sdk/whatsapp`, or
channel-branded helper seams. Bundled plugins should compose generic
SDK subpaths inside their own `api.ts` or `runtime-api.ts` barrels, and core
should either use those plugin-local barrels or add a narrow generic SDK
contract when the need is truly cross-channel.

The generated export map still contains a small set of bundled-plugin helper
seams such as `plugin-sdk/feishu`, `plugin-sdk/feishu-setup`,
`plugin-sdk/zalo`, `plugin-sdk/zalo-setup`, and `plugin-sdk/matrix*`. Those
subpaths exist for bundled-plugin maintenance and compatibility only; they are
intentionally omitted from the common table below and are not the recommended
import path for new third-party plugins.

## Subpath reference

The most commonly used subpaths, grouped by purpose. The generated full list of
200+ subpaths lives in `scripts/lib/plugin-sdk-entrypoints.json`.

Reserved bundled-plugin helper subpaths still appear in that generated list.
Treat those as implementation detail/compatibility surfaces unless a doc page
explicitly promotes one as public.

## Registration API

The `register(api)` callback receives an `OpenClawPluginApi` object with these
methods:

| `api.registerHook(events, handler, opts?)`     | Event hook                              |
| `api.registerHttpRoute(params)`                | Gateway HTTP endpoint                   |
| `api.registerGatewayMethod(name, handler)`     | Gateway RPC method                      |
| `api.registerCli(registrar, opts?)`            | CLI subcommand                          |
| `api.registerService(service)`                 | Background service                      |
| `api.registerInteractiveHandler(registration)` | Interactive handler                     |
| `api.registerMemoryPromptSupplement(builder)`  | Additive memory-adjacent prompt section |
| `api.registerMemoryCorpusSupplement(adapter)`  | Additive memory search/read corpus      |

Reserved core admin namespaces (`config.*`, `exec.approvals.*`, `wizard.*`,
`update.*`) always stay `operator.admin`, even if a plugin tries to assign a
narrower gateway method scope. Prefer plugin-specific prefixes for
plugin-owned methods.

### CLI registration metadata

`api.registerCli(registrar, opts?)` accepts two kinds of top-level metadata:

- `commands`: explicit command roots owned by the registrar
- `descriptors`: parse-time command descriptors used for root CLI help,
  routing, and lazy plugin CLI registration

If you want a plugin command to stay lazy-loaded in the normal root CLI path,
provide `descriptors` that cover every top-level command root exposed by that
registrar.

```typescript
api.registerCli(
  async ({ program }) => {
    const { registerMatrixCli } = await import("./src/cli.js");
    registerMatrixCli({ program });
  },
  {
    descriptors: [
      {
        name: "matrix",
        description: "Manage Matrix accounts, verification, devices, and profile state",
        hasSubcommands: true,
      },
    ],
  },
);
```

Use `commands` by itself only when you do not need lazy root CLI registration.
That eager compatibility path remains supported, but it does not install
descriptor-backed placeholders for parse-time lazy loading.

### CLI backend registration

`api.registerCliBackend(...)` lets a plugin own the default config for a local
AI CLI backend such as `codex-cli`.

- The backend `id` becomes the provider prefix in model refs like `codex-cli/gpt-5`.
- The backend `config` uses the same shape as `agents.defaults.cliBackends.<id>`.
- User config still wins. OpenClaw merges `agents.defaults.cliBackends.<id>` over the
  plugin default before running the CLI.
- Use `normalizeConfig` when a backend needs compatibility rewrites after merge
  (for example normalizing old flag shapes).

### Exclusive slots

| Method                                     | What it registers                     |
| ------------------------------------------ | ------------------------------------- |
| `api.registerContextEngine(id, factory)`   | Context engine (one active at a time) |
| `api.registerMemoryCapability(capability)` | Unified memory capability             |
| `api.registerMemoryPromptSection(builder)` | Memory prompt section builder         |
| `api.registerMemoryFlushPlan(resolver)`    | Memory flush plan resolver            |
| `api.registerMemoryRuntime(runtime)`       | Memory runtime adapter                |

### Memory embedding adapters

| Method                                         | What it registers                              |
| ---------------------------------------------- | ---------------------------------------------- |
| `api.registerMemoryEmbeddingProvider(adapter)` | Memory embedding adapter for the active plugin |

- `registerMemoryCapability` is the preferred exclusive memory-plugin API.
- `registerMemoryCapability` may also expose `publicArtifacts.listArtifacts(...)`
  so companion plugins can consume exported memory artifacts through
  `openclaw/plugin-sdk/memory-host-core` instead of reaching into a specific
  memory plugin's private layout.
- `registerMemoryPromptSection`, `registerMemoryFlushPlan`, and
  `registerMemoryRuntime` are legacy-compatible exclusive memory-plugin APIs.
- `registerMemoryEmbeddingProvider` lets the active memory plugin register one
  or more embedding adapter ids (for example `openai`, `gemini`, or a custom
  plugin-defined id).
- User config such as `agents.defaults.memorySearch.provider` and
  `agents.defaults.memorySearch.fallback` resolves against those registered
  adapter ids.

### Events and lifecycle

| Method                                       | What it does                  |
| -------------------------------------------- | ----------------------------- |
| `api.on(hookName, handler, opts?)`           | Typed lifecycle hook          |
| `api.onConversationBindingResolved(handler)` | Conversation binding callback |

### Hook decision semantics

- `before_tool_call`: returning `{ block: true }` is terminal. Once any handler sets it, lower-priority handlers are skipped.
- `before_tool_call`: returning `{ block: false }` is treated as no decision (same as omitting `block`), not as an override.
- `before_install`: returning `{ block: true }` is terminal. Once any handler sets it, lower-priority handlers are skipped.
- `before_install`: returning `{ block: false }` is treated as no decision (same as omitting `block`), not as an override.
- `reply_dispatch`: returning `{ handled: true, ... }` is terminal. Once any handler claims dispatch, lower-priority handlers and the default model dispatch path are skipped.
- `message_sending`: returning `{ cancel: true }` is terminal. Once any handler sets it, lower-priority handlers are skipped.
- `message_sending`: returning `{ cancel: false }` is treated as no decision (same as omitting `cancel`), not as an override.

### API object fields

| `api.config`             | `OpenClawConfig`          | Current config snapshot (active in-memory runtime snapshot when available)                  |
| `api.pluginConfig`       | `Record<string, unknown>` | Plugin-specific config from `plugins.entries.<id>.config`                                   |

## Internal module convention

Within your plugin, use local barrel files for internal imports:

```
my-plugin/
  api.ts            # Public exports for external consumers
  runtime-api.ts    # Internal-only runtime exports
  index.ts          # Plugin entry point
  setup-entry.ts    # Lightweight setup-only entry (optional)
```

<Warning>
  Never import your own plugin through `openclaw/plugin-sdk/<your-plugin>`
  from production code. Route internal imports through `./api.ts` or
  `./runtime-api.ts`. The SDK path is the external contract only.
</Warning>

Facade-loaded bundled plugin public surfaces (`api.ts`, `runtime-api.ts`,
`index.ts`, `setup-entry.ts`, and similar public entry files) now prefer the
active runtime config snapshot when OpenClaw is already running. If no runtime
snapshot exists yet, they fall back to the resolved config file on disk.

Provider plugins can also expose a narrow plugin-local contract barrel when a
helper is intentionally provider-specific and does not belong in a generic SDK
subpath yet. Current bundled example: the Anthropic provider keeps its Claude
stream helpers in its own public `api.ts` / `contract-api.ts` seam instead of
promoting Anthropic beta-header and `service_tier` logic into a generic
`plugin-sdk/*` contract.

Other current bundled examples:

- `@openclaw/openai-provider`: `api.ts` exports provider builders,
  default-model helpers, and realtime provider builders
- `@openclaw/openrouter-provider`: `api.ts` exports the provider builder plus
  onboarding/config helpers

<Warning>
  Extension production code should also avoid `openclaw/plugin-sdk/<other-plugin>`
  imports. If a helper is truly shared, promote it to a neutral SDK subpath
  such as `openclaw/plugin-sdk/speech`, `.../provider-model-shared`, or another
  capability-oriented surface instead of coupling two plugins together.
</Warning>
