This MCP server defines 6 read-only Git inspection tools with reasonable naming (verb-noun convention) and complete input schemas. However, descriptions lack depth and actionability, they explain WHAT tools do but rarely explain WHEN to use them or how they chain together. Most parameter descriptions are minimal (often just restating the parameter name). Output schemas are not documented, forcing LLMs to infer response structure. Error handling is absent from tool definitions. All tools are read-only (low risk), but the lack of rich context makes this a C-grade implementation suitable for Git inspection workflows but not production-grade agent orchestration.

• Add output schema documentation to every tool. Document the structure, field names, types, and meanings of returned objects. E.g., hug_log should document it returns an array of commit objects with fields: {commit_hash: string, message: string, author: string, date: ISO8601}.
• Expand tool descriptions from single sentences to 2-3 sentences that answer: What does this tool do? When should I use it instead of similar tools? What does it return? Example: 'hug_log shows commit history with messages and metadata. Use this to understand change history over time. Call hug_h_files if you need to see which files were modified in a commit.'
• Add per-parameter guidelines in descriptions. For numeric parameters (count, minimum, default values), state typical ranges. For enum-like parameters (format: 'short'|'long'), replace examples with formal constraints. For temporal parameters, define the exact format (ISO 8601, RFC 3339, or 'relative strings like "3 days ago"' with validation rules).
• Rename 'hug_h_files' to 'get_commit_files' and 'hug_h_steps' to 'get_steps_to_file_change' for clarity. These names better match LLM expectations and avoid domain-specific abbreviations that require prior knowledge.
• Add mutual-exclusivity documentation. E.g., in hug_h_files, note that 'commit' and 'count' are mutually exclusive, and 'temporal' overrides 'count' if both are provided.
• Implement error documentation pattern. For each tool, document expected error conditions: 'Returns error if file path is invalid or does not exist. Suggestion: verify the file exists in the current branch.' This guides LLM recovery.
