Mixed quality across 23 tools. Strengths: all tools have descriptions (10-200 chars, mostly adequate); input schemas present with type definitions for most parameters. Weaknesses: descriptions are often generic and lack actionable context (e.g., 'Create a Git branch' vs 'Create a feature branch for isolated development; use conventional names like feature/*, bugfix/*, or hotfix/*'); many parameters lack detailed constraints or format guidance; no documented output schemas; error handling is minimal; tool annotations (readOnlyHint, destructiveHint) are absent despite clear risk levels (WRITE, DESTRUCTIVE). Composition is reasonable, tools are single-purpose, but chaining context is missing (e.g., create_branch output should include branch name for downstream push/commit calls). Exa and Ref tools delegate to external APIs, reducing local schema visibility.

• Add tool annotations: mark merge_pr, commit, push, bump_version, create_release with destructiveHint=true; mark repo_info, check_ci, get_latest_tag with readOnlyHint=true. This guides agent caution and prevents accidental destructive calls.
• Document output schemas for all tools. For repo_info, specify: {branch: string, changes: {staged: string[], unstaged: string[]}, commits: {hash: string, message: string}[]}. For web_search_exa, specify: {results: [{title: string, url: string, snippet: string}], total: number}.
• Enhance descriptions with constraints and context. E.g., 'Create a feature branch (naming: feature/*, bugfix/*, hotfix/*). If branch exists, fails with 'branch already exists', use checkout to switch instead. Returns branch name for downstream push/commit calls.'
• Add error recovery guidance. E.g., merge_pr: 'If merge fails due to conflicts, return error with conflict details and suggest resolve_conflicts tool or manual resolution steps.'
• For Exa/Ref tools, document expected response structure in descriptions or add a separate schema reference. E.g., 'Returns {results: [{title, url, snippet}], total_count}' for web_search_exa.
