Server has 5 tools with basic schemas and minimal descriptions. All tools have input schemas with type definitions, but descriptions are extremely terse (10-35 chars, well below the 50-200 char baseline for LLM-optimized tools). Parameter descriptions are completely absent, only parameter names and types are present. No output schemas documented. Error handling is minimal (generic 404/status errors). Tools lack verb-noun naming convention (e.g., 'module' should be 'get_module'). No pagination support despite search tool returning potentially large result sets. No tool annotations (readOnlyHint, etc.). This is a functional but minimal implementation.

• Rename tools to verb_noun pattern: 'get_module', 'list_versions', 'get_version', 'search_modules', 'get_dependencies'. This enables LLMs to parse intent from names alone.
• Expand tool descriptions to 80-150 chars. Example: 'Get metadata and latest version for a Deno module. Use this to check if a module exists and see its current release. Returns name, description, star count, and latest version tag.'
• Add parameter descriptions to all inputs. Example for 'limit': 'Maximum number of search results to return (1-100, default 20). Larger limits may slow queries.'
• Document output schemas for each tool. Example: 'Returns {name: string, description: string, star_count: number, latest_version: string, upload_options?: {dependencies?: Record<string, string>}}'.
• Add pagination to search tool: accept 'offset' parameter, return 'total_count' and 'has_more' fields, and document in description: 'Results are paginated; use offset to fetch additional pages.'
