Key Patterns & Gotchas

• Two workspaces supported via workspace parameter ("primary" / "secondary")
• getChannelHistory auto-joins channels on "not_in_channel" error, then retries — requires channels:join scope
• If auto-join fails, throws a detailed message explaining how to invite the bot
• searchMessages may require user token; bot token tried first
• listChannels paginates via cursor; only first page is cached
• getUserInfo resolves bots via getBotInfo when needed
