Server has 4 well-named tools with complete input schemas and reasonable descriptions. All tools follow verb_noun naming (get_*, search_*, summarize_*). Schemas include proper types and descriptions for all parameters. However, output schemas are not formally documented, responses are plain text strings rather than structured objects. Error handling returns error strings inline rather than guiding recovery. Parameter descriptions lack constraint details (e.g., no mention of valid language code formats, no bounds on gap_seconds/min_chunk_seconds). Tool descriptions are adequate (100-200 chars) but could better explain when to use each tool vs. alternatives.

• Return structured JSON objects instead of plain text. E.g., get_transcript should return {transcript: string, duration_seconds: number, language: string, has_timestamps: boolean} so LLMs can extract and chain data.
• Add constraint details to parameter descriptions: 'languages: ISO 639-1 codes (e.g., en, fr, de, en-GB). Defaults to ["en"].' and 'gap_seconds: silence threshold in seconds (0.1 - 60, default 4).'
• Enhance error messages with recovery guidance. Instead of 'Error: No transcript found...', return 'No transcript in [en]. Try: search_transcript with a different language, or check if captions are disabled.'
• Document output schemas in tool descriptions. E.g., 'Returns: {matches: [{timestamp: string, text: string}], count: number, query: string}'.
• Add result limits and pagination hints. E.g., 'search_transcript returns up to 50 matches; use offset/limit parameters for additional results.' (requires schema update).
