The txcript MCP server exposes a single tool 'search' with minimal definition quality. The tool has a basic description ('Fuzzy/substring search over transcripts') and a simple input schema with two parameters (query: string, limit: integer). However, critical gaps exist: no output schema is documented, parameter descriptions are minimal (query and limit lack context about expected formats, ranges, or constraints), no error handling guidance is provided, and the description lacks WHEN/WHY context for LLM selection. The tool name 'search' is generic and lacks a verb prefix (should be 'search_transcripts'). No tool annotations (readOnlyHint, idempotentHint) are present. The server appears to be a thin wrapper around the txcript library's search functionality, but the MCP interface does not follow production-grade tool definition patterns.

• Rename tool from 'search' to 'search_transcripts' to follow verb_noun convention and improve LLM intent recognition.
• Document the complete output schema: return type (array of objects?), fields (transcript_id, content, timestamp, match_score, speaker?), and field types. Include example response.
• Add parameter constraints: 'limit' should specify range (1 - 100, default 20); 'query' should clarify format (fuzzy string, case-insensitive, supports partial word matches).
• Expand tool description to 100 - 200 characters explaining WHAT (search transcripts), WHEN (to find messages by content/speaker), and WHAT IT RETURNS (matching messages with context).
• Add tool annotations: mark as readOnlyHint=true (search does not modify state) and idempotentHint=true (repeated calls with same input return same results).
