Extensions Boundary

This directory contains bundled plugins. Treat it as the same boundary that third-party plugins see.

Public Contracts

• Docs:
  • docs/plugins/building-plugins.md
  • docs/plugins/architecture.md
  • docs/plugins/sdk-overview.md
  • docs/plugins/sdk-entrypoints.md
  • docs/plugins/sdk-runtime.md
  • docs/plugins/sdk-channel-plugins.md
  • docs/plugins/sdk-provider-plugins.md
  • docs/plugins/manifest.md
• Definition files:
  • src/plugin-sdk/plugin-entry.ts
  • src/plugin-sdk/core.ts
  • src/plugin-sdk/provider-entry.ts
  • src/plugin-sdk/channel-contract.ts
  • scripts/lib/plugin-sdk-entrypoints.json
  • package.json

Boundary Rules

• Extension production code should import from openclaw/plugin-sdk/* and its own local barrels such as ./api.ts and ./runtime-api.ts.
• Do not import core internals from src/**, src/channels/**, src/plugin-sdk-internal/**, or another extension's src/**.
• Do not use relative imports that escape the current extension package root.
• Keep plugin metadata accurate in openclaw.plugin.json and the package openclaw block so discovery and setup work without executing plugin code.
• Plugin runtime dependencies belong to the owning plugin package. If a plugin dependency has a runtime peer, declare/provide it in that plugin's package.json; do not move it to root unless root/package dist owns the import. Runtime never installs deps; install/update/doctor are repair points.
• Keep plugin dependency assertions in generic contracts (package-manifest.contract.test.ts, extension-runtime-dependencies.contract.test.ts) rather than plugin e2e tests when they express package ownership.
• Treat files like src/**, onboard.ts, and other local helpers as private unless you intentionally promote them through api.ts and, if needed, a matching src/plugin-sdk/<id>.ts facade.
• If core or core tests need a bundled plugin helper, export it from api.ts first instead of letting them deep-import extension internals.
• For provider plugins, keep auth, onboarding, catalog selection, and vendor-only product behavior local to the plugin. Do not move those into core just because two providers look similar.
• Before adding a new provider-local wrapStreamFn, buildReplayPolicy, normalizeToolSchemas, inspectToolSchemas, or compat patch helper, check whether the same behavior already exists through openclaw/plugin-sdk/*. Reuse shared family helpers first.
• If two bundled providers share the same replay policy shape, tool-schema compat rewrite, payload patch, or stream-wrapper chain, stop copying the logic. Extract one shared helper and migrate both call sites in the same change.
• Prefer named provider-family helpers over repeating raw option bags. If a provider needs OpenAI-style Anthropic tool payload compat, Gemini schema cleanup, or an XAI compat patch, use a named shared helper instead of inlining the policy knobs again.
• Keep control-plane metadata separate from runtime logic. Discovery, config validation, setup hints, onboarding hints, and activation planning should be expressible from manifest/descriptors whenever possible.
• If setup truly requires runtime execution, make that explicit in the plugin's declared setup/runtime surface instead of letting metadata flows import runtime code accidentally.
• Do not rely on eager global registry seeding or import-time side effects to make a plugin “available”. Plugin availability should come from manifest ownership plus targeted activation.
• When core needs plugin-owned static data on a hot path, expose a lightweight top-level artifact such as gateway-auth-api.ts, message-tool-api.ts, or a similarly narrow *-api.ts. Reuse the same local helper from the artifact and the full plugin so fast paths do not drift from runtime behavior.

Expanding The Boundary

• If an extension needs a new seam, add or replace a typed Plugin SDK subpath instead of reaching into core.
• ALL bundled plugins must move to modern SDK seams in the same change. Do not keep extension-local compat paths for internal callers.
• When intentionally expanding the contract, update the docs, exported subpath list, package exports, and API/contract checks in the same change.
