Server provides 5 well-scoped Git analysis tools with complete input schemas and Italian descriptions. All tools are READ_ONLY and follow verb_noun naming (repositoryOverview, fileHistory, blameLines, searchHistory, inspectCommit). Schemas are properly typed with required fields marked. However, descriptions are brief (avg ~80 chars) and lack actionable context for LLM selection. No output schemas documented. Parameter descriptions are minimal, e.g., 'Percorso relativo del file nel repository' lacks format guidance or examples. No error handling guidance visible. Tool composition is sound (each does one thing), but descriptions don't explain WHEN to use each tool vs. alternatives or what downstream tools might need.

• Document output schemas for all 5 tools. Specify: field names, types (string, integer, array, object), required vs. optional, and what each field represents. Example: repositoryOverview returns {branch: string, commit_hash: string, author: string, timestamp: ISO8601, stats: {files_changed: int, insertions: int, deletions: int}}.
• Expand parameter descriptions to 50 - 150 chars with format constraints. E.g., 'filePath: Relative path from repo root (e.g., src/main.java). Max 255 chars, no ../ traversal.' For searchHistory.query: 'Literal string search in commit messages and diffs. Case-sensitive. Max 256 chars.'
• Add WHEN/WHY context to tool descriptions. E.g., fileHistory: 'Shows all commits affecting a file, including renames and deletions. Use this to understand a file's evolution; use blameLines to attribute specific lines to commits.' Baseline: 150 - 250 chars.
• Include error recovery hints in descriptions. E.g., 'If file not found, verify the path is relative to repo root and the file exists in the current branch. Call repositoryOverview first to confirm branch and recent files.'
• Ensure output includes chaining IDs. If fileHistory returns commits, include commit_hash so LLM can call inspectCommit. If searchHistory finds commits, return commit_hash, author, timestamp, and message_preview to enable downstream analysis.
