The server defines 11 tools across multiple example files. While tool names follow action-verb conventions and input schemas are present with proper JSON Schema structure, descriptions are minimal (many under 50 chars), parameter annotations are sparse or missing, and output schemas are entirely undocumented. Tool definitions appear duplicated (github_search_repos, github_list_issues, github_create_issue, github_create_pr each appear twice), suggesting either incomplete tool registry management or example file fragmentation. No error guidance, no output structure documentation, and no parameter validation constraints visible. This is typical of proof-of-concept code that has not been hardened for production agent use.

• Deduplicate tool registry: merge the four duplicated tool definitions (github_search_repos×2, github_list_issues×2, github_create_issue×2, github_create_pr×2) into single canonical entries with proper tool composition logic.
• Expand descriptions to 50 - 150 chars with explicit WHEN guidance: 'Search GitHub repositories by query string (keywords, language, stars) to discover open-source projects. Returns up to 30 results; use pagination for more.'
• Document output schemas for every tool. For github_list_issues, specify: {issues: [{id, number, title, state, created_at, user: {login}}], total_count, has_more}. For fetch_html/txt, specify: {content: string, status: int, url: string}.
• Add parameter descriptions: fetch_html headers → 'Optional HTTP headers object (e.g., {"Authorization": "Bearer token", "User-Agent": "agent/1.0"})'; github_search_repos query → 'Search query using GitHub search syntax (e.g., "language:rust stars:>1000").'
• Implement pagination for github_list_issues: add limit (1 - 100, default 20) and page (1 - N) parameters; return total_count and next_page indicator.
• Add tool annotations via schema extensions: mark github_create_issue and github_create_pr with destructiveHint: true so agents know these are write operations; mark fetch_html/txt with idempotentHint: true (safe to retry).
• Implement error recovery: if github API returns 404, respond with 'Repository not found. Check owner and repo name. Available repos: [suggestions]. Did you mean: <similar name>?'
• Add confirmation flow for destructive ops: tools should support a dry_run parameter or return a confirmation_required response before actual execution (Multi Round-Trip Request pattern).
