xyz-go exhibits significant quality gaps across naming, descriptions, and schema completeness. Tool names lack clear action verbs (e.g., 'user.add' should be 'create_user'; 'user.rm' should be 'delete_user'). Descriptions are minimal (10-20 chars), well below the 50-200 char LLM-optimized baseline. Parameter descriptions exist but are sparse. Schemas are present but lack depth, no min/max bounds, no format constraints, no output schema documentation. The 'net.head' tool exposes API keys as parameters (critical security violation). Error handling and recovery guidance are absent. Only 2 of 11 tools have descriptions exceeding 20 characters.

• Expand all tool descriptions to 50-200 characters. Example: 'user.add' → 'Create a new user account with name, email, and optional age/tags. Returns user_id for downstream operations. Required: name. Optional: email, age (default 18), mode (fast|slow), tags, limit, verbose.'
• Rename tools to verb_noun pattern: user.add → create_user, user.list → list_users, user.rm → delete_user, sys.port → listen_port, net.head → check_api_key_injection.
• Add output schema documentation for each tool. Example for user.add: 'Returns {user_id: string, name: string, email: string, created_at: ISO8601, status: string}'.
• Remove 'key' parameter from net.head. Inject API keys server-side via environment variables. If testing is needed, accept a 'test_mode' boolean flag instead.
• Add numeric bounds and enum constraints to parameters. Example: search.query.k should be 'integer, min 1, max 100, default 10'. sys.sleep.d should document valid duration formats (e.g., '100ms', '5s', '1m').
