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({/* ... */});  },});

• id must match your openclaw.plugin.json manifest.

• External session catalogs use openclaw/plugin-sdk/session-catalog and register a SessionCatalogProvider with api.registerSessionCatalog(...). Required provider fields are id, label, list, and read; optional hooks are resolveCreateSession, continueSession, copyToGatewaySession, checkUpstreamActivity, archive, openTerminal, and startTerminalSession. Core owns the sessions.catalog.* Gateway methods; providers return host, session, transcript, and terminal-plan projections without registering RPCs. A list provider should call the optional onHost(host) callback as each host settles; the returned host array remains required as the final compatibility snapshot.

  If a host can finish after list returns a fail-soft snapshot, register its bounded completion with the optional waitUntil(completion: Promise<void>) hook before list settles. Include host mapping and the onHost call in that promise. Use publishSessionCatalogHost({ onHost, waitUntil }, pendingHost) from the same SDK entry point to publish the host and register the complete callback chain. Registration after list settles is rejected. Providers that do not register completion work finish publishing when their list settles.

  The optional signal: AbortSignal belongs to the catalog operation or provider lifetime. Pass it to cancellable work, including the top-level signal field of api.runtime.nodes.invoke(...). A requesting client disconnect only removes that client's subscription; it does not cancel shared discovery. Retaining completion does not extend native invocation or fail-soft response deadlines, grant new authority, or permit starting work after the owner retires. Providers remain responsible for bounded work that settles after cancellation.

  Keep onHost, waitUntil, and signal separate from validated catalog query objects and node command payloads. The request-owned sessionEntries snapshot and listNodes hook still must not be retained past list; prepare any facts needed by late host mapping before returning.

  Transcript items may include a sender with a qualified SessionParticipant identity and optional display label or avatar. Supply only source-known attribution; the viewer and the session adopter are not transcript authors. Core resolves profile identities against current profile data, including merges. User items without attribution display as User.

  A Gateway-hosted catalog may set audience: "gateway-operators" when every authenticated operator with operator.read may view its rows. Such a provider may implement copyToGatewaySession(...) to return a bounded display name and optional preferred model for an independent Gateway-owned continuation. Core owns operator and agent authorization, session creation, model readiness and policy checks, rollback, and untrusted-content wrapping. The provider supplies transcript text through read(...); it must not write the destination session.

  Native source titles are presentation, not unique session labels. When adopting a new source, pass its title as displayName to the owner-authorized session creator; the host bounds and stores that snapshot with the new row. Keep source identity independent of naming, preserve existing labels and snapshots on reuse or recovery, and do not resync native renames.

  A provider may declare one readable transcript route with shareRoute. This is a closed contract, not a free-form routing hint:

  const shareRoute = {  kind: "thread-id-prefix",  routeSegment: "my-sessions",  hostId: "gateway",  identifierAlphabet: "lowercase-hex",  fullLength: 32,  minPrefixLength: 12,  lookup: "catalog-list-search-by-thread-id-prefix",  ambiguity: "multiple-results-or-next-cursor",} as const;

  The provider must return lowercase hexadecimal threadId values of exactly 32 characters on the declared host. When list(...) receives a search value that is a valid 12-32 character prefix, that host must return only rows whose threadId starts with the prefix. Return every match up to the requested limit and set nextCursor when more may exist. The Control UI resolves only one result with no next page; multiple rows or nextCursor are explicitly ambiguous and never select the first row.

  Named share links use /<routeSegment>/<title-slug>-<id-prefix> with the same bounded slug as regular session links. Return the title in the catalog row's name; the Control UI uses it to refresh the decorative slug. Only the id suffix selects the transcript. Bare-id and stale-title links remain valid, and titles never resolve an ambiguous id.

  routeSegment must not use the first segment of a built-in Control UI route or alias, and it must be unique across active session catalogs. Invalid, unsupported, reserved, or multiply owned descriptors fail closed; catalog sessions remain available through the generic /chat/<agent>?catalog=...&host=...&thread=... URL. The shared session URL contract owns the built-in reservation decision: its share-path builder returns null for reserved segments, and the Gateway omits reserved descriptors before publishing catalogs. Keep one plugin-owned descriptor constant and reuse it for registration, prefix lookup, and URL generation so those obligations cannot drift.

  CLI-backed catalogs that expose the same local-plus-paired-node shape can use createSessionCatalogFamily(...). The family composer owns canonical cursor validation, node payload validation, host projection, adopted-session projection, per-host publication, read routing, single-flight continuation per resolved agent and source, and terminal plan routing. Different agents do not share in-flight adoption results; adopted-source lookup keys remain host/thread pairs. The provider must supply its local store reads, identifiers and commands, error text, capability projection, continuation availability and persistence operations, upstream-activity check, and terminal executable/arguments. There are no default continuation, capability-mutation, or terminal authorities. Use createSessionCatalogNodeHostBindings(...) to build the matching list/read/terminal node commands and terminal-only invoke policy from those explicit provider inputs.

  The same entrypoint exports sessionCatalogPaging, which groups the bounded list/read parameter parsers, canonical base64url cursor codec, and bounded UTF-8 transcript pager. Providers pass their own identifier pattern and validation messages into parseReadParams(...) and parseListParams(...).

  resolveCreateSession({ agentId }) must return a config-derived model/runtime target before OpenClaw advertises model-chat creation. Native terminal readiness is independent of this target. Use api.runtime.agent.resolveSessionCatalogCreateTarget(...) to apply the host's runtime and model-allowlist policy instead of duplicating it.

  startTerminalSession advertises capabilities.startTerminal: true independently of model-chat creation. Return canStartTerminal: true on each eligible host from the ordinary catalog list callback, including empty hosts. Publish the same flag in progressive onHost frames and final results; explicitly return false when readiness changes. A failed transcript listing does not revoke an otherwise available CLI. Node hosts require their exact connected, invocable fresh-start command; start-only nodes must not invoke a missing list command. Preserve local source IDs and process-home isolation. The shipped createSession.startTerminal field remains model-chat metadata; new terminal callers use the independent capability and raw catalog hosts.

  startTerminalSession({ agentId, cwd, initialMessage?, nodeId?, hostId? }) creates a fresh CLI terminal plan. Return either a local plan (kind: "local", argv, and the exact cwd, plus optional env, pathEnv, and title) or a paired-node plan (kind: "node", nodeId, command, paramsJSON, and the exact cwd). The sessions.catalog.startTerminal RPC requires operator.admin plus gateway.cliAgents.enabled and gateway.terminal.enabled. The caller provisions cwd; the Gateway requires an existing absolute local directory, rejects a changed plan cwd or host, and applies the normal agent-sandbox, node-pairing, deadline, and connection-ownership checks before opening the PTY. hostId carries the selected local source; nodeId identifies a node. Initial prompts are bounded to 16,384 characters and cwd to 4,096 characters (4,096 UTF-8 bytes on nodes). Fresh node commands use decodeNodePtyStartParams from node-host and runNodePtyCommand({ ..., requiredCwd: true }, io) to require an existing absolute node directory, including a recheck immediately before spawning. Resume retains its existing cwd fallback contract. Node payloads must not accept executable, argv, environment, credentials, or a Gateway agent as native account selection.

  Paired-node plans that run an interactive CLI directly can declare uploadPathStyle: "native" when it accepts double-quoted POSIX paths and simple double-quoted Windows drive or UNC paths as file references. Native Windows formatting preserves apostrophes and backslashes, and rejects double quotes and control characters. Declare the same contract through terminal.uploadPathStyle in createSessionCatalogFamily(...). Leave the field absent for shells or other input syntaxes. The Gateway includes it in terminal.upload results only for clients advertising terminal-upload-path-style. Without an upload style, clients use the terminal's shell quoting rules.

  The terminal manager retains the native title and actual connection/agent owner across attach and reconnect. Clients advertise terminal-session-metadata to receive attach title/owner and list titles; older closed response shapes stay unchanged.

• kind is deprecated: declare an exclusive slot ("memory" or "context-engine") in the openclaw.plugin.json manifest kind field instead. Runtime-entry kind remains only as a compatibility fallback for older plugins.

• configSchema can be a function for lazy evaluation. OpenClaw resolves and memoizes the schema on first access, so expensive schema builders only run once.

• A nodeHostCommands descriptor can define isAvailable({ config, env }). Returning false omits that command and its capability from the headless node's Gateway declaration. OpenClaw evaluates it against the node-local startup config; command handlers should still validate availability when invoked.
