Server has 41 tools with consistent naming (verb_noun pattern) and descriptions present for all. However, parameter descriptions are minimal (typically 1-2 lines), output schemas are not documented, and error handling guidance is absent. Most tools accept a 'format' parameter but lack constraints (enum). No evidence of pagination support despite many list/get tools. Security model is sound (no secrets in params, server-side injection via lifespan context), but tool composition could be tighter, several tools do similar things (e.g., moodle_get_user_courses vs moodle_get_enrolled_courses_by_user). Average tool description ~80 chars, below the 194-char baseline for A+ tools.

• Document output schemas for all tools. Specify field names, types, and which IDs/references are returned for chaining. Example: moodle_get_user_profile should document that it returns user_id, email, username, and full_name.
• Add enum constraints to the 'format' parameter across all tools. Change from free-form string to enum: ['markdown', 'json']. This prevents invalid values and self-documents valid options.
• Implement pagination for list/search tools. Add limit (default 20, max 100) and offset/cursor parameters. Document total_count or next_cursor in output. Prevents context window exhaustion.
• Consolidate overlapping tools. Merge moodle_list_user_courses and moodle_get_enrolled_courses_by_user into one canonical tool. Merge moodle_get_calendar_events and moodle_get_upcoming_events. Reduces LLM confusion.
• Add error recovery guidance to tool descriptions. Example: 'If user not found, call moodle_search_users() with a partial name or email.' Include actionable next steps for common failure modes (not found, permission denied, invalid input).
