The server defines 3 tools with names that follow verb_noun convention (get_components, get_node, get_workflow). Tool descriptions exist but are minimal (34-200 chars) and lack context about when to use each tool or what differentiates them. Parameter descriptions are present but inconsistent in quality. Schemas are visible but incomplete, parameters lack explicit type declarations in some cases. Error handling is basic (returns error dicts) but does not guide recovery. No output schemas documented. The codebase shows tool definitions via @mcp.tool() decorators with descriptions in docstrings, making them verifiable. However, per the rubric's conservative calibration, community STDIO servers typically land in the 50-59 range, and this server's gaps (missing output schema documentation, minimal descriptions, no parameter constraints) prevent a higher score.

• Document output schemas for each tool. Example: 'Returns list of dicts with keys: {id (string), name (string), description (string)}' for get_components.
• Expand tool descriptions to 50-200 chars with explicit WHEN/WHY guidance. Example: 'Get all reusable components from a Figma file. Call this first to understand what design elements are available before fetching specific nodes. Returns component IDs, names, and descriptions.'
• Add constraint descriptions to parameters. Example for file_key: 'The Figma file key (24+ alphanumeric chars, found in shared URL after /file/ segment). Example: do4pJqHwNwH1nBrrscu6Ld'.
• Add node_id format constraint to get_node description: 'The node ID in colon format (e.g. 0:3). If you have hyphenated URL format (0-3), the tool will auto-convert.'
• Implement actionable error messages. On 401, return: 'Authentication failed. Verify FIGMA_API_TOKEN environment variable is set and valid.' On 404, return: 'File not found. Check file_key matches the Figma URL segment (e.g. do4pJqHwNwH1nBrrscu6Ld).'
• Add limit parameter to get_components with default 50, document: 'Maximum components to return (1-500, default 50). Set higher for large design systems, lower for faster queries.'
• Clarify tool selection: add to get_workflow description 'Returns prototype interaction connections (transitions). Use get_node for individual node details, get_components for reusable design elements, and get_workflow for flow diagrams.'
• Add examples to parameter descriptions (in code comments, not docstrings). Example: 'node_id: The ID in format x:y. E.g., if Figma URL has node-id=0-3, use node_id=0:3'.
