220220A session reads its own thread and its channel. Mentioning `@Claude` partway into an existing thread gives it a window of the thread's messages, not the whole thread, with other bots' replies filtered out. In long threads, restate anything critical.

222Claude works in channels it has been added to, but workspace search can still find messages by keyword from public channels it's not a member of (the same search any Slack user has). Workspace search is unavailable in [channels that include guests](/docs/claude-tag/admins/restrict-access#restrict-guest-channels). Finding something is broader than being able to act somewhere; to have it participate in a channel directly, invite it with `/invite @Claude`.
