Single tool 'find_overlaps' has a reasonable name and description (89 chars), but critical gaps undermine quality. Input schema is visible with array type and description, but lacks critical constraints: no enum for tool names, no format validation, no min/max array bounds. Parameter description mentions examples ('HubSpot', 'Salesforce') which violates the pattern of using enums instead. Output schema is completely undocumented, the client code shows result.content[0]?.text but no formal schema is declared. No error handling guidance, no pagination support despite potentially returning large overlap matrices, no per-tool success/failure breakdown. The tool does one thing (find overlaps) which is good, but the definition lacks the rigor expected of production tools.

• Add formal output schema: {type: 'object', properties: {overlaps: {type: 'array', items: {type: 'object', properties: {tool_a: string, tool_b: string, overlap_percentage: number, cost_savings: string}}}, total_count: number, next_cursor?: string}}
• Replace example values with enum constraint: tools parameter should list all valid tool names (HubSpot, Salesforce, Outreach, ZoomInfo, etc.) as enum values
• Add min/max constraints: tools array must have min 2 items, max 10 items; each tool name 2-50 chars
• Add error handling guidance to description: 'Returns empty overlaps if tool names are invalid. Call with known tool names from the StackSwap registry.'
• Add pagination: accept optional limit (1-100, default 20) and cursor parameters; return next_cursor if more results exist
