This server has severe definition quality gaps. Tool descriptions are present but minimal (10-30 chars), far below the 50-200 char LLM-optimized baseline. Most parameters lack type information in visible schemas, only 'state' and 'payload' show Path types; others are inferred. No output schemas documented. Error handling is absent. Tools like 'start_session' and 'show_session' are vague about what state they manage. The naming is inconsistent: 'preference_show' vs 'preference_always' lacks verb-noun clarity. No tool declares permissions, error recovery paths, or idempotency guarantees. This is a D-grade server with fundamental definition deficiencies.

• Expand all tool descriptions to 50-200 characters. Example: 'start_session' should explain: 'Initialize a new task-scoped session for tracking SolidWorks feedback submissions. Creates or loads session state file to track payload builds and feedback IDs. Call this before marking payloads or submitting feedback.'
• Document output schemas for all tools. Example: 'show_session' should return {session_id: string, created_at: ISO8601, payloads: [{part_id, part_number, timestamp}], feedback_ids: [string]}.
• Rename preference tools: 'preference_show' → 'get_preference', 'preference_always' → 'set_preference_always', 'preference_clear' → 'clear_preference' for verb-noun clarity.
• Add error handling guidance to 'submit_feedback': document retryable errors (network timeout, 5xx), user-fixable errors (invalid payload), and fatal errors (auth failure). Include recovery hints.
• Enhance parameter descriptions with context. For 'state' param, add: 'Session state file tracks feedback submissions and build history. Defaults to .sw-learner-state.json in current directory. Created automatically if missing.'
