title: "Plugin SDK subpaths"
---

The plugin SDK contains narrow public subpaths and repository-only bundled
helpers under `openclaw/plugin-sdk/`. This page catalogs every typed public
subpath and labels selected private-local entries explicitly; it is not an
inventory of every internal runtime helper. Four files define the boundary:

- `scripts/lib/plugin-sdk-entrypoints.json`: the maintained entrypoint inventory
  the build compiles.
- `scripts/lib/plugin-sdk-private-local-only-subpaths.json`: internal subpaths
  excluded from the typed, documented SDK. Production entries remain available
  as JavaScript-only host runtime exports for separately published official
  plugins; test-only entries stay unexported.
- `scripts/lib/plugin-sdk-deprecated-public-subpaths.json`: public compatibility
  subpaths retained only through their documented removal windows.
- `scripts/lib/plugin-sdk-entries.mts`: derived public/private export metadata,
  supported bundled facades, and plugin-owned public surfaces.

Maintainers audit the public export count with `pnpm plugin-sdk:surface` and
the compatibility queue with `pnpm plugins:boundary-report:summary`.

For the plugin authoring guide, see [Plugin SDK overview](/plugins/sdk-overview).

| `plugin-sdk/provider-entry`         | Private-local after July 2026; `defineSingleProviderPluginEntry`                                                                                                                                        |

| `plugin-sdk/health`                 | Doctor health-check registration, detection, repair, selection, severity, and finding types for bundled health consumers                                                                                |

### Compatibility and private-local helpers

Only the later-window deprecated subpaths remain exported. July 2026 aliases and
unused subpaths were deleted, while bundled-only helpers were removed from the
public package and are labeled private-local below. The maintained list is
`scripts/lib/plugin-sdk-deprecated-public-subpaths.json`; CI rejects bundled
imports of these compatibility-only subpaths. The broad domain barrels
`plugin-sdk/agent-runtime`, `plugin-sdk/channel-lifecycle`,
`plugin-sdk/conversation-runtime`, `plugin-sdk/hook-runtime`,
`plugin-sdk/media-runtime`, `plugin-sdk/plugin-runtime`, and
`plugin-sdk/security-runtime` are likewise deprecated in favor of focused
subpaths.

OpenClaw's Vitest-backed test-helper subpaths are repo-local only and are no
longer package exports: `agent-runtime-test-contracts`,
`channel-contract-testing`, `channel-target-testing`, `channel-test-helpers`,
`plugin-state-test-runtime`, `plugin-test-api`, `plugin-test-contracts`,
`plugin-test-runtime`, `provider-http-test-mocks`, `provider-test-contracts`,
`reply-payload-testing`, `sqlite-runtime-testing`, `test-env`, `test-fixtures`,
`test-live`, `test-live-auth`, `test-media-generation`,
`test-media-understanding`, `test-node-mocks`, and `testing`.
`ssrf-runtime-internal` is a JavaScript-only host runtime reserved for exact
trusted local-service plugins; it is not a public plugin authoring API.

### Bundled plugin helper subpaths

Bundled-only helper modules are private-local after the July 2026 sweep.
Package contract guardrails classify the supported bundled facades that remain
public until generic contracts replace them. Those facades are deprecated for
new code; see the per-row notes below.

registry dates. July aliases such as direct-DM access, reply-options, pairing
paths, and channel runtime splinters have been removed; bundled-only helpers
are private-local.

  </Accordion>

`createBoundedProviderBinaryStream` requires a request `cleanup` callback.
Stream cancellation and `release()` start source cancellation, unlock the reader,
and run cleanup once, then wait for both operations. Cancellation propagates
source failures; `release()` ignores them. Cleanup failures take precedence in
both cases. Overflow preserves its fitting prefix and error without waiting for
cleanup; later `release()` reports cleanup failure. After EOF or a read error,
the caller must still invoke and await `release()`.

Provider usage snapshots normally report one or more quota `windows`, each with
a label, percent used, and optional reset time. Providers that expose balance or
account-state text instead of resettable quota windows should return
`summary` with an empty `windows` array rather than fabricating percentages.
OpenClaw displays that summary text in status output; use `error` only when the
usage endpoint failed or returned no usable usage data.

  </Accordion>

Use `isLoopbackHost(host)` when a plugin must accept only the local machine. It accepts `localhost`, IPv4 loopback literals across `127.0.0.0/8`, `::1`, bracketed IPv6, and IPv4-mapped IPv6 loopback literals. It parses IP literals rather than matching text prefixes, so a DNS name such as `127.0.0.1.evil.com` is not loopback. Use `isPrivateOrLoopbackHost(host)` only when private-network hosts such as RFC 1918 addresses are also valid.

  <Accordion title="Runtime and storage subpaths">

  <Accordion title="Reserved bundled-helper subpaths">
    Reserved bundled-helper SDK subpaths are narrow owner-specific surfaces for
    bundled plugin code. They are tracked in the SDK inventory so package
    builds and aliasing stay deterministic, but they are not general plugin
    authoring APIs. New reusable host contracts should use generic SDK subpaths
    such as `plugin-sdk/gateway-runtime` and `plugin-sdk/ssrf-runtime`.

    | Subpath | Owner and purpose |
