Server has 9 tools with consistent naming (verb_noun pattern) and basic descriptions. All tools are READ_ONLY, reducing risk. However, descriptions are generic (avg ~60 chars, well below the 194-char baseline for A+ tools), parameter descriptions lack detail about constraints and formats, and output schemas are not documented. Tools return JSON strings rather than structured objects, forcing LLMs to parse unstructured text. No error handling guidance, no pagination support despite list tools, and no tool annotations (readOnlyHint, etc.). GitHub tools lack enum constraints for 'state' parameters. RAG tools lack documentation of index format and search scoring. Overall: functional but below production baseline.

• Expand tool descriptions to 100 - 200 chars. Example: 'github_list_issues: List open/closed/all issues in a GitHub repository. Returns issue metadata (title, state, labels, assignee, created_at). Use this to discover issues before fetching details or creating related PRs. Supports filtering by labels and limiting results.'
• Add enum constraints to 'state' parameters in JSON Schema: {"type": "string", "enum": ["open", "closed", "all"], "description": "Issue state filter..."}
• Document output schemas in tool descriptions. Example: 'Returns a JSON object with fields: id (int), title (string), state (string), labels (array of strings), assignee (object with login, id), created_at (ISO 8601 date).'
• Add offset/cursor pagination to list tools. Example: github_list_issues(owner, repo, state='open', labels='', limit=10, offset=0) → returns {issues: [...], total_count: 42, has_more: true}
• Wrap error handling with actionable messages. Example: if client is None, return 'GitHub tools unavailable: GITHUB_TOKEN environment variable not set. Configure it and restart the server.' instead of raising RuntimeError.
