This server has a single tool with a moderately clear name but lacks essential definition quality. The tool description is present but generic (97 chars, below the 194-char baseline for A+ tools). Input schema is visible with basic type information, but parameter descriptions are minimal and lack actionable constraints. No output schema is documented, the tool returns a dict with 'summary', 'action_items', and 'decisions_made' fields, but this structure is inferred from example_usage.py, not formally specified in the tool definition. The tool lacks error handling guidance, no idempotency hints, and no guidance on when to use it vs. alternative approaches. This is characteristic of a prototype rather than a production-grade tool.

• Document the complete output schema including field types and nullability: { summary: string, action_items: [{ owner: string, task: string, due: string (ISO 8601) }], decisions_made: [string] }
• Expand tool description to 150-200 chars, answering: (1) What formats are supported (plaintext, JSON with speaker labels)? (2) How are speakers matched to participants? (3) Does it handle multi-language or accented speaker names? Example: 'Extracts action items, summary, and decisions from meeting transcripts. Speakers must be clearly labeled (e.g. 'Speaker: text'). Supports plaintext and JSON transcripts. Returns structured action items with assigned owners and deadlines.'
• Add explicit parameter constraints: transcript_text should specify 'Plaintext or JSON transcript. Must include speaker labels (e.g., 'Alice: ...'). Minimum 100 characters. Supports English, Spanish, French.' participant_names should specify 'Optional. If provided, names used to disambiguate speakers in transcript. Example: ["Alice Smith", "Bob Johnson"]. Names are matched case-insensitively to speaker labels.'
• Add error handling guidance: 'If no action items are detected, response returns empty action_items array. If speaker names cannot be matched, use transcript speaker labels as-is in owner field. Retry with clearer speaker labels if accuracy is low.'
• Add idempotency and read-only annotations to the tool schema: { idempotentHint: true, readOnlyHint: true }
• Define valid output constraints: Ensure 'due' dates are ISO 8601 strings (YYYY-MM-DD) or document fallback (null if not detected). Specify that summary is a paragraph (not bullets) and decisions_made is an array of 1-sentence statements.
