Tools

tool	what it does
`postbridge_accounts`	List connected accounts with their ids. Call this first.
`postbridge_upload_media`	Upload a local image or video, returns a media id.
`postbridge_post`	Publish or schedule one post to any subset of accounts.
`postbridge_list_posts`	List existing and scheduled posts.
`postbridge_results`	Read per-account results for a post.

Five tools on purpose: the smallest set that covers a real workflow. An agent choosing from a long list of near-identical tools chooses worse, so analytics, media listing and post editing are left to npx postbridge-cli.

Notes for anyone building an OpenClaw plugin

Three things the published SDK docs get wrong, each found by building against OpenClaw's own type definitions and then actually installing the result:

registerTool takes a SINGLE object, not ({id, inputSchema}, {handler}). Its parameters field is a TypeBox schema, not JSON Schema.
definePluginEntry requires id, name and description alongside register. The docs example passes register alone and does not compile.
package.json must contain openclaw.extensions pointing at the built entry, for example ["./dist/index.js"]. This appears nowhere in the SDK docs and only surfaces as an install-time error.

Develop

bash

npm install
npm run build
openclaw plugins install --link . --force --accept-capabilities
openclaw plugins inspect post-bridge --runtime --json
