This server exposes 5 tools for querying Google's deps.dev API. While all tools have basic schemas and descriptions, the implementation has significant gaps: (1) Parameter descriptions lack detail, most are single-word or generic (e.g., 'system_' has no format guidance, 'query' just says 'Query body'); (2) No enum constraints on system_ or project_type despite known valid values; (3) Output schemas are completely undocumented, LLMs cannot plan downstream calls; (4) Error messages are minimal and non-actionable; (5) Tool names lack action verbs (e.g., 'project', 'package', 'version' are nouns, not verb_noun patterns like 'get_project', 'get_package'); (6) No pagination support documented despite deps.dev API likely returning large result sets. The code shows basic input validation but no guidance for LLM recovery.

• Rename tools to verb_noun pattern: get_project, get_package, get_version, get_dependencies, query_packages. This makes intent explicit and helps LLMs disambiguate.
• Add enum constraints to schemas: system_ should be enum: ['NPM', 'PYPI', 'GO', 'MAVEN', 'NUGET', 'CARGO', 'RUBYGEMS']; project_type should be enum: ['github', 'gitlab', 'bitbucket'].
• Expand parameter descriptions with format and constraints. E.g., 'system_: Package ecosystem (one of: NPM, PYPI, GO, MAVEN, NUGET, CARGO, RUBYGEMS)' and 'project_key: Repository identifier in format owner/repo (e.g., facebook/react)'.
• Document output schemas for each tool. Specify returned fields, types, and which IDs are available for chaining. E.g., 'Returns: {project: {key, name, repo_url}, ...}'.
• Improve error messages with recovery guidance. E.g., 'Package not found. Try query_packages() to search by hash or repo URL' or 'Invalid system: got "npm", must be one of: NPM, PYPI, GO, MAVEN, NUGET, CARGO, RUBYGEMS'.
