Nine tools with basic descriptions and schemas, but significant gaps in parameter documentation and error handling. Tool names follow verb_noun convention (send, join, part, connect, list_*, get_*, whois). Descriptions exist but are terse (10-50 chars), below the 50-200 char baseline for LLM optimization. Most parameters lack descriptions entirely, e.g., 'send' tool has 'target', 'text', 'server' with minimal guidance on format or constraints. No enum constraints on channel names or server keys. No documented output schemas. Error handling absent, no recovery guidance, no actionable error messages. Composition is reasonable (each tool does one thing), but parameter naming could be clearer (e.g., 'target' vs 'channel' or 'user_nick' for disambiguation).

• Expand all tool descriptions to 50-200 characters. Include WHAT, WHEN, and any side effects. E.g., 'Send a message to an IRC channel or user. Use after join() to post in a channel. Messages are sent immediately and cannot be edited.'
• Add descriptions to every parameter. For 'target' in send, specify: 'Channel name (e.g., #general) or user nickname for direct message. Required.' For 'limit' in get_messages, add: 'Maximum messages to retrieve (1-100, default 20).'
• Document output schemas for all tools. E.g., list_channels returns {channels: [{name: string, users: number, topic: string}], total: number}. This enables tool chaining.
• Add error handling with recovery hints. E.g., 'Channel not found. Call list_channels() to see available channels.' or 'Connection failed: server offline. Retry in 30s or try a different server.'
• Constrain 'server' parameter with enum of configured server keys or document default behavior. Add 'limit' bounds (1-100) and 'port' bounds (1-65535) to numeric parameters.
