Two tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Tool names follow verb_noun convention (list_, run_) which is good. However, the run_git_quick_stats tool has 14 parameters with minimal descriptions, most lack guidance on format, constraints, or when to use them. No output schema documented for either tool. Error handling is absent from descriptions. The server exposes git-quick-stats functionality but does not optimize the interface for LLM reasoning.

• Add detailed descriptions to all 14 parameters in run_git_quick_stats. For each, specify: valid values/format, when to use it, and any constraints. Example: 'since: Start date for filtering commits (ISO 8601 format, e.g. 2025-01-01). Only used with options that support date filtering.'
• Document the output schema for both tools. For list_git_quick_stats_options, specify the structure of the returned dict (e.g. {option_name: {description, requires_env, stdin_hint}}). For run_git_quick_stats, document whether output is JSON, plain text, or structured object, and what fields/format to expect.
• Add enum constraints to the 'option' parameter in run_git_quick_stats. Extract valid options from OPTION_SPECS keys and declare them as an enum in the schema so LLMs see valid choices.
• Add bounds to numeric parameters: limit (1 - 1000?), days (1 - 365?), timeout_seconds (1 - 3600?). Include these in both the schema and parameter descriptions.
• Add error handling guidance to run_git_quick_stats description: 'Returns error if repo_path is not a git repository, option is unsupported, or timeout_seconds is exceeded. If timeout occurs, increase timeout_seconds or simplify the query.'
