Critical gaps across all dimensions. Tool descriptions are in Chinese and extremely brief (5-15 chars), far below the 10-1024 char baseline. Input schemas present but lack proper type definitions for most parameters, many are inferred from context rather than explicitly declared. No output schemas documented. Parameters lack descriptions in English (descriptions exist only in Chinese). No error handling guidance. Tools like poll_for_messages and process_pending_messages have empty input schemas but no documentation of side effects. The server exposes internal queue mechanics (msg_id, status enums) rather than abstracting them. No security considerations visible (credentials, permissions, audit trails). Composition is poor: send_message, send_to_hermes, and poll_for_messages overlap in responsibility without clear delineation.

• Rewrite all tool descriptions in English, 50-200 chars each, answering: What does it do? When to use it? What does it return? Example: 'send_message: Queue a message from one agent to another. Use to initiate async communication. Returns message_id for tracking.'
• Add English descriptions to every parameter. For 'status', specify: 'Message status filter: pending (not yet processed), processing (in progress), completed (success), failed (error). Default: pending.'
• Document output schemas for all tools. E.g., get_messages returns {messages: [{id, timestamp, sender, receiver, content, status}], total_count, next_cursor}.
• Add error handling guidance. E.g., mark_as_processed: 'Returns {success: true, processed_at} on success. If msg_id not found, returns {success: false, error: "Message not found. Call get_messages() to list available messages."}.'
• Clarify tool composition: document that send_message is internal queue API, send_to_hermes is the public interface, and poll_for_messages is a background worker, not meant for direct agent calls.
