RepoFather MCP exposes 9 specialized analysis tools with clear domain focus (repository scoring, launch readiness, compliance). However, critical gaps undermine production readiness: (1) Parameter descriptions are sparse or missing entirely, most tools accept 'files' (object) and 'packageJson' (unknown type) with minimal guidance on expected structure; (2) Output schemas are completely undocumented, no tool declares what fields it returns, forcing LLMs to guess; (3) Error handling is absent, no recovery guidance, retryability classification, or actionable error messages; (4) Tool names lack action verbs (e.g., 'score_repository_snapshot' vs 'analyze_repository', 'generate_launch_assets' is vague about what 'assets' means); (5) Descriptions are domain-specific but lack LLM-optimization, they assume domain knowledge rather than explaining WHEN to call each tool vs. alternatives. The 'unknown' type for packageJson violates schema rigor. No tool documents pagination, limits, or response structure. Composition is reasonable (each tool has one concern), but chaining is impossible without documented outputs.

• Document output schema for every tool. Example: 'Returns {score: number (0-100), launchReadiness: string, viralityFactors: string[], recommendations: string[]}'. This enables LLMs to chain tools and extract data.
• Replace 'packageJson: unknown' with 'packageJson: object' and add description: 'Parsed package.json object with keys: name (string), version (string), description (string), dependencies (object), devDependencies (object), scripts (object), keywords (array), license (string), repository (object), homepage (string).'
• Add description to 'files' parameter: 'Map of repository-relative file paths to file content strings. Example: {"README.md": "# Project...", "package.json": "{...}", "src/index.ts": "export..."}. Include at least README, package.json, and key source files.'
• Add error handling to tool descriptions. Example: 'Returns analysis results or error object {error: string, retryable: boolean, suggestion: string}. If files are malformed, returns retryable error with guidance on expected format.'
• Rename tools to use clearer action verbs: 'score_repository_snapshot' → 'analyze_repository_readiness', 'generate_launch_assets' → 'create_launch_copy', 'repo_context_pack' → 'extract_agent_context'. Add 1-2 sentence descriptions explaining WHEN to call each vs. alternatives.
