1# Channel Publish
2 
3Publish through Channel Accounts. Limits come from `get_channel_platform`, not from this file.

5## Environment
6 
7Some domestic platforms are not available on this edition — treat `list_channel_platforms` as the source of truth and never promise an unlisted platform. When the user asks to publish to a platform that is not listed, say it is not supported here and guide them to the domestic edition.

9## Tools
10 
11- `list_channel_accounts` / `get_channel_account`: pick `accountId` and platform. Account `status`: `1` usable, `0` offline (authorization lost) — only `status: 1` accounts can publish. Not required for plugin publish (`xhs / wxSph`, see Workflow step 1).
12- `list_channel_platforms`: directory of publish support and assembled tool ids. For `authType==='plugin'` platforms (`xhs / wxSph`) `assembledToolIds` is empty — `create_rednote/wechat_channels_publish_flow` does not exist and is not searchable via `toolSearch`.
13- `get_channel_platform`: required before create. Follow the returned text for title, body, media count/format/duration, cover, topics, and publish mode. For `xhs / wxSph` it returns “不支持服务端发布，请使用浏览器插件发布（guide_{slug}_plugin_publish）”.
14- `list_channel_publish_records` / `get_channel_publish_record`: inspect flows and tasks. Use `flowId` / `taskId` to get `ChannelPublishRecord.id(recordId)` when you need a `recordId`.
