This git server has 11 tools with inconsistent quality. Naming is verb-forward and clear (git_clone, git_status, git_commit, etc.), which is good. However, tool descriptions are short and lack context about when to use each tool vs. alternatives. Parameter descriptions are present but minimal. Input schemas are properly defined with Zod and converted to JSON Schema, but output schemas are completely undocumented, tools return generic text content with no structure. Error handling is basic and often returns raw error strings without recovery guidance. The server demonstrates basic MCP patterns but lacks the production-grade polish expected in a B-tier tool. Most significantly: no output schema documentation, no tool annotations (readOnly/destructive hints), and tool descriptions average ~50 chars (well below the 194-char production baseline).

• Document output schemas for all tools. Specify what fields are returned (e.g., git_log returns commit hashes, authors, messages; git_branch returns branch names and tracking info). Use structured JSON responses, not raw text.
• Expand tool descriptions to 100 - 200 chars. Include: WHAT the tool does, WHEN to use it vs. alternatives, WHAT data is returned. Example: 'Get the current state of a repository: untracked files, staged changes, commit history. Use before committing to see what will be included.'
• Add tool annotations: mark git_clone, git_pull, git_push, git_commit, git_checkout, git_add, git_init, git_remote with destructiveHint: true and appropriate idempotency guidance.
• Improve error messages with recovery guidance. Example: Instead of 'repository "invalid-url" does not exist', return 'Repository URL invalid or unreachable. Verify URL format (https://...) and network access. You may need to authenticate with git config.'
• Add limit/pagination to git_log. Accept 'limit' (default 20, max 100) and 'offset' (or 'skip'). Return total commit count so agents know if more data exists.
• Document parameter constraints in descriptions. E.g., 'directory' for git_clone: 'Target directory path. If omitted, clones to a folder named after the repo.' Add length/format constraints to all string parameters.
• Implement permission checks and audit logging. Gate destructive operations (push, force-push, delete) behind authorization checks. Log caller identity, tool name, parameters, and outcome to stderr or a structured audit trail.
