Tiger-Slack presents a solid foundation with 7 well-named, read-only tools backed by clear descriptions and proper parameter schemas. All tools follow verb_noun naming (getChannels, getConversationsInChannel, search) and descriptions are substantive (average ~100 chars). Parameter schemas are present with type declarations and descriptions for all parameters. However, critical gaps prevent a higher score: (1) Output schemas are NOT documented anywhere in the code provided, no TypeScript return types visible in tool definitions, no response field listings, no guidance on what fields the agent should expect; (2) No pagination support despite tools returning potentially large result sets (getChannels, getConversationsInChannel could return hundreds of items); (3) Error handling is not visible, no evidence of actionable error messages, recovery guidance, or invalid-input feedback; (4) Some descriptions lack specificity about use cases and prerequisite conditions. The codebase references `@tigerdata/mcp-boilerplate` which likely provides the HTTP transport layer, but tool-specific implementation details for error handling and response shaping are not visible in the provided source excerpts.

• Document output schemas for all 7 tools. For each, specify the returned object structure, field types, and descriptions. Example: getChannels should document that it returns [{ id: string; name: string; topic?: string; created_at: ISO8601 }]. Make schemas visible in code (TypeScript interfaces or JSDoc comments).
• Add pagination to list-returning tools: getChannels, getUsers, getConversationsInChannel, search. Accept optional limit (1 - 100, default 20) and offset or cursor parameters. Return total_count or next_cursor in responses. Document in descriptions: 'Returns up to 20 channels per page.'
• Implement structured error handling with recovery guidance. For example: if channelId is not found, return { error: 'Channel not found', code: 'CHANNEL_NOT_FOUND', available_channels: ['general', 'random', 'dev'] } so the LLM can self-correct. Document error codes in tool descriptions.
• Support human-friendly identifiers. Enhance getConversationsInChannel, getMessageContext, getThreadMessages, and search to accept channelName or channelId (try name first, fall back to ID). This reduces forced discovery calls and matches chat data model (users say '#general', not 'C12345').
• Enrich tool descriptions with prerequisite and context hints. For example: 'Call getChannels first if you only have a channel name' for getConversationsInChannel. Clarify distinctions: 'Use getMessageContext for surrounding messages, getThreadMessages for all messages in a thread.'
• Add response field cleanup. Strip internal database columns (created_at timestamps, audit fields) unless essential. Return only fields agents need: id, name, message text, sender, timestamp. Every extra token costs money and dilutes signal.
