| Reference for defineToolPlugin, definePluginEntry, defineChannelPluginEntry, and defineSetupPluginEntry | Plugin entry points | Entry Points |
|
Every plugin exports a default entry object. The SDK provides a helper for
each entry shape: defineToolPlugin, definePluginEntry,
defineChannelPluginEntry, defineSetupPluginEntry.
Package entries
Installed plugins point package.json openclaw fields at both source and
built entries:
{
"openclaw": {
"extensions": ["./src/index.ts"],
"runtimeExtensions": ["./dist/index.js"],
"setupEntry": "./src/setup-entry.ts",
"runtimeSetupEntry": "./dist/setup-entry.js"
}
}
extensionsandsetupEntryare source entries, used for workspace and git checkout development.runtimeExtensionsandruntimeSetupEntryare preferred for installed packages: they let npm packages skip runtime TypeScript compilation.runtimeExtensions, when present, must matchextensionsin array length (entries pair positionally).runtimeSetupEntryrequiressetupEntry.- If a
runtimeExtensions/runtimeSetupEntryartifact is declared but missing, install/discovery fails with a packaging error; OpenClaw does not silently fall back to source. Source fallback (below) only applies when no runtime entry is declared at all. - If an installed package declares only a TypeScript source entry, OpenClaw
looks for a matching built
dist/*.js(or.mjs/.cjs) peer and uses it; otherwise it falls back to the TypeScript source. - All entry paths must stay inside the plugin package directory. Runtime
entries and inferred built-JS peers do not make an escaping
extensionsorsetupEntrysource path valid.
defineToolPlugin
Import: openclaw/plugin-sdk/tool-plugin
For plugins that only add agent tools. Keeps the source small, infers config
and tool-parameter types from TypeBox schemas, wraps plain return values in
the OpenClaw tool-result format, and exposes static metadata that
openclaw plugins build writes into the plugin manifest (contracts.tools,
configSchema).
import { Type } from "typebox";
import { defineToolPlugin } from "openclaw/plugin-sdk/tool-plugin";
export default defineToolPlugin({
id: "stock-quotes",
name: "Stock Quotes",
description: "Fetch stock quotes.",
configSchema: Type.Object({
apiKey: Type.Optional(Type.String({ description: "API key." })),
}),
tools: (tool) => [
tool({
name: "quote",
label: "Quote",
description: "Fetch a quote.",
parameters: Type.Object({
symbol: Type.String({ description: "Ticker symbol." }),
}),
execute: async ({ symbol }, config) => ({ symbol, hasKey: Boolean(config.apiKey) }),
}),
],
});
configSchemais optional; omitting it uses a strict empty object schema (the generated manifest still includesconfigSchema).executereturns a plain string or JSON-serializable value; the helper wraps it as a text tool result withdetailsset to the original (unstringified) return value.- For custom tool results,
openclaw/plugin-sdk/tool-resultsexportstextResultandjsonResult. - Tool names are static, so
openclaw plugins buildderivescontracts.toolsfrom the declared tools without hand-duplicated names. - Runtime loading stays strict: installed plugins still need
openclaw.plugin.jsonandpackage.jsonopenclaw.extensions. OpenClaw never executes plugin code to infer missing manifest data.
definePluginEntry
Import: openclaw/plugin-sdk/plugin-entry
For provider plugins, advanced tool plugins, hook plugins, and anything that is not a messaging channel.
import { definePluginEntry } from "openclaw/plugin-sdk/plugin-entry";
export default definePluginEntry({
id: "my-plugin",
name: "My Plugin",
description: "Short summary",
register(api) {
api.registerProvider({
/* ... */
});
api.registerTool({
/* ... */
});
},
});

idmust match youropenclaw.plugin.jsonmanifest.kindis deprecated: declare an exclusive slot ("memory"or"context-engine") in theopenclaw.plugin.jsonmanifestkindfield instead. Runtime-entrykindremains only as a compatibility fallback for older plugins.configSchemacan be a function for lazy evaluation. OpenClaw resolves and memoizes the schema on first access, so expensive schema builders only run once.
defineChannelPluginEntry
Import: openclaw/plugin-sdk/channel-core
Wraps definePluginEntry with channel-specific wiring: it automatically
calls api.registerChannel({ plugin }), exposes an optional root-help CLI
metadata seam, and gates registerFull on registration mode.
import { defineChannelPluginEntry } from "openclaw/plugin-sdk/channel-core";
export default defineChannelPluginEntry({
id: "my-channel",
name: "My Channel",
description: "Short summary",
plugin: myChannelPlugin,
setRuntime: setMyRuntime,
registerCliMetadata(api) {
api.registerCli(/* ... */);
},
registerFull(api) {
api.registerGatewayMethod(/* ... */);
},
});

Callbacks run per registration mode (full table under Registration mode):
setRuntimeruns in every mode except"cli-metadata"and"tool-discovery". Store the runtime reference here, typically viacreatePluginRuntimeStore.registerCliMetadataruns for"cli-metadata","discovery", and"full". Use it as the canonical place for channel-owned CLI descriptors so root help stays non-activating, discovery snapshots include static command metadata, and normal CLI registration stays compatible with full plugin loads.registerFullruns only for"full"and"tool-discovery". For"tool-discovery"it runs instead of channel registration: OpenClaw skipsregisterChannel/setRuntimeentirely and calls onlyregisterFull, so any provider/tool registration your channel needs for standalone tool discovery or execution must live there, not behind normal channel setup.- Discovery registration is non-activating, not import-free: OpenClaw may
evaluate the trusted plugin entry and channel plugin module to build the
snapshot. Keep top-level imports side-effect-free and put sockets,
clients, workers, and services behind
"full"-only paths. - Like
definePluginEntry,configSchemacan be a lazy factory; OpenClaw memoizes the resolved schema on first access.
CLI registration:
- Use
api.registerCli(..., { descriptors: [...] })for plugin-owned root CLI commands you want lazy-loaded without disappearing from the root CLI parse tree. Descriptor names must match letters, numbers, hyphen, and underscore, starting with a letter or number; OpenClaw rejects other shapes and strips terminal control sequences from descriptions before rendering help. Cover every top-level command root the registrar exposes.commandsalone stays on the eager compatibility path. - Use
api.registerNodeCliFeature(...)for paired-node feature commands so they land underopenclaw nodes(equivalent toregisterCli(registrar, { parentPath: ["nodes"], ... })). - For other nested plugin commands, add
parentPathand register commands on theprogramobject passed to the registrar; OpenClaw resolves it to the parent command before calling the plugin. - For channel plugins, register CLI descriptors from
registerCliMetadataand keepregisterFullfocused on runtime-only work. - If
registerFullalso registers gateway RPC methods, keep them on a plugin-specific prefix. Reserved core admin namespaces (config.*,exec.approvals.*,wizard.*,update.*) always coerce tooperator.admin.
defineSetupPluginEntry
Import: openclaw/plugin-sdk/channel-core
For the lightweight setup-entry.ts file. Returns just { plugin } with no
runtime or CLI wiring.
import { defineSetupPluginEntry } from "openclaw/plugin-sdk/channel-core";
export default defineSetupPluginEntry(myChannelPlugin);
OpenClaw loads this instead of the full entry when a channel is disabled, unconfigured, or when deferred loading is enabled. See Setup and Config for when this matters.
Pair defineSetupPluginEntry(...) with the narrow setup helper families:
| Import | Use for |
|---|---|
openclaw/plugin-sdk/setup-runtime |
Runtime-safe setup helpers: createSetupTranslator, import-safe setup patch adapters, lookup-note output, promptResolvedAllowFrom, splitSetupEntries, delegated setup proxies |
openclaw/plugin-sdk/channel-setup |
Optional-install setup surfaces |
openclaw/plugin-sdk/setup-tools |
Setup/install CLI, archive, and docs helpers |
Keep heavy SDKs, CLI registration, and long-lived runtime services in the full entry.
Bundled workspace channels that split setup and runtime surfaces can use
defineBundledChannelSetupEntry(...) from
openclaw/plugin-sdk/channel-entry-contract instead. It lets the setup
entry keep setup-safe plugin/secrets exports while still exposing a runtime
setter:
import { defineBundledChannelSetupEntry } from "openclaw/plugin-sdk/channel-entry-contract";
export default defineBundledChannelSetupEntry({
importMetaUrl: import.meta.url,
plugin: {
specifier: "./channel-plugin-api.js",
exportName: "myChannelPlugin",
},
runtime: {
specifier: "./runtime-api.js",
exportName: "setMyChannelRuntime",
},
registerSetupRuntime(api) {
api.registerHttpRoute({
path: "/my-channel/events",
auth: "plugin",
handler: async (req, res) => {
/* setup-safe route */
},
});
},
});
Use this only when a setup flow truly needs a lightweight runtime setter or
setup-safe gateway surface before the full channel entry loads.
registerSetupRuntime runs only for "setup-runtime" loads; keep it
limited to config-only routes or methods that must exist before deferred
full activation.
Registration mode
api.registrationMode tells your plugin how it was loaded:
| Mode | When | What to register |
|---|---|---|
"full" |
Normal gateway startup | Everything |
"discovery" |
Read-only capability discovery | Channel registration plus static CLI descriptors; entry code may load, but skip sockets, workers, clients, and services |
"tool-discovery" |
Scoped load to list or run specific plugins' tools | Capability/tool registration only; no channel activation |
"setup-only" |
Disabled/unconfigured channel | Channel registration only |
"setup-runtime" |
Setup flow with runtime available | Channel registration plus only the lightweight runtime needed before the full entry loads |
"cli-metadata" |
Root help / CLI metadata capture | CLI descriptors only |
defineChannelPluginEntry handles this split automatically. If you use
definePluginEntry directly for a channel, check mode yourself and remember
"tool-discovery" skips channel registration:
register(api) {
if (
api.registrationMode === "cli-metadata" ||
api.registrationMode === "discovery" ||
api.registrationMode === "full"
) {
api.registerCli(/* ... */);
if (api.registrationMode === "cli-metadata") return;
}
if (api.registrationMode === "tool-discovery") {
// Register capability-only surfaces (providers/tools), no channel.
return;
}
api.registerChannel({ plugin: myPlugin });
if (api.registrationMode !== "full") return;
// Heavy runtime-only registrations
api.registerService(/* ... */);
}
Discovery mode builds a non-activating registry snapshot. It may still evaluate the plugin entry and the channel plugin object so OpenClaw can register channel capabilities and static CLI descriptors. Treat module evaluation in discovery as trusted but lightweight: no network clients, subprocesses, listeners, database connections, background workers, credential reads, or other live runtime side effects at top level.
Treat "setup-runtime" as the window where setup-only startup surfaces must
exist without re-entering the full bundled channel runtime. Good fits are
channel registration, setup-safe HTTP routes, setup-safe gateway methods,
and delegated setup helpers. Heavy background services, CLI registrars, and
provider/client SDK bootstraps still belong in "full".
Plugin shapes
OpenClaw classifies loaded plugins by their registration behavior:
| Shape | Description |
|---|---|
| plain-capability | One capability type (e.g. provider-only) |
| hybrid-capability | Multiple capability types (e.g. provider + speech) |
| hook-only | Only hooks, no capabilities |
| non-capability | Tools/commands/services but no capabilities |
Use openclaw plugins inspect <id> to see a plugin's shape.
