This server has critical gaps in definition quality. Tool names lack action verbs (module, versions, version_info, go_mod are nouns or incomplete verbs). Descriptions are extremely terse (8-27 chars, well below the 50-200 char baseline for LLM-optimized tools). No parameter descriptions exist, LLMs cannot infer what module_path or version mean. Output schemas are completely undocumented. Error handling is minimal (raw HTTP status codes). The server reads from an external API but provides no guidance on rate limits, timeouts, or recovery. Tool composition is reasonable (each does one thing), but the interface is opaque to LLMs.

• Rename tools with action verbs: get_module, list_versions, get_version_info, get_go_mod. This lets LLMs infer intent from the name alone.
• Expand descriptions to 80 - 150 chars each. Example: 'get_module: Fetch the latest version and metadata (time, hash, go.mod) for a Go module. Use this to check the current stable release.' Include when to use it and what it returns.
• Add descriptions to every parameter. Example: 'module_path (string, required): Go module import path (e.g., github.com/gin-gonic/gin). Must be a valid Go module name.' Include format constraints and examples.
• Document output schemas in tool descriptions or as a separate schema field. Example: 'Returns {Version: string, Time: ISO8601, Hash: string}.' This enables LLMs to plan chained calls.
• Enhance error messages with recovery guidance. Instead of 'Go proxy: 404', return 'Module not found. Verify the module path is correct (e.g., github.com/user/repo). Check https://pkg.go.dev for available modules.' This guides the LLM to self-correct.
