Critical gaps across all dimensions. Tool definitions are inferred from examples (stdio-client/index.mjs) rather than visible in source code, no explicit schema registration found in provided code. Descriptions are present but generic (10-60 chars, well below 50-200 char baseline). No input schemas visible in source. Parameters undocumented. No output schema documentation. Error handling absent. This server fails to meet production-grade tool definition standards.

• Add explicit JSON Schema definitions for all tools in create-server.ts. Each tool must register with server.tool() including inputSchema with type, properties, required, and descriptions for every parameter.
• Expand tool descriptions to 50-200 characters. Example: 'generate_issue' should be: 'Generate a structured GitHub issue from provided details. Validates title, body, and labels before creation. Returns a formatted issue object ready for create_github_issue. Call this first to preview the issue before committing.'
• Document every parameter with type and constraints. Example: 'title' (string, 1-200 chars, required), 'body' (string, optional, supports markdown), 'labels' (array of strings, max 5, must exist in repo).
• Add output schema documentation in tool descriptions or as a separate schema field. Example: 'Returns {issue_id: string, url: string, number: integer, created_at: ISO8601}' so LLMs know what fields to expect for chaining.
• Implement error handling with recovery guidance. Wrap GitHub API calls with try-catch that returns structured errors: '{error: 'not_found', message: 'Repository not found', suggestion: 'Verify GITHUB_OWNER and GITHUB_REPO environment variables'}'.
