BrewMe exhibits significant definition quality gaps across all dimensions. While 21 tools are registered with basic descriptions (10-50 chars, well below the 194-char baseline), most lack depth and actionable guidance. Input schemas are present but minimal: parameters have types and brief descriptions, but lack enums for constrained values, format specifications, and dependency documentation. Output schemas are entirely undocumented, LLMs cannot predict response structure or chain tools effectively. Error handling is absent; no recovery guidance, categorization, or actionable error messages. Naming is generally verb-first (good), but several tools conflate multiple concerns (e.g., 'computer_use' with generic 'action' parameter). No evidence of idempotency guarantees, pagination support, or rate-limiting. Security concerns: 'computer_use' and 'ingest_content' accept broad parameters without validation hints. Overall, this server reads as a rapid prototype rather than production-grade tooling.

• Document output schemas for all 21 tools. Specify field names, types, and required fields. Example: 'Returns {subscription_id: string, name: string, platform: string, enabled: boolean, created_at: ISO8601}'. This enables tool chaining.
• Expand descriptions to 100-200 chars. Add WHEN to call, WHAT it returns, and any prerequisites. Example: 'List all subscriptions or filter to enabled ones. Call this first to discover available feeds before ingesting content. Returns array of {subscription_id, name, platform, enabled}.'
• Add enum constraints to all string parameters. Replace 'platform' free-form with enum: ['youtube', 'bilibili', 'rss']. Replace 'status' with enum: ['pending', 'running', 'completed', 'failed']. Replace 'audit_type' with enum: ['accessibility', 'performance', 'all'].
• Implement error handling patterns. Return structured errors with recovery hints: '{error: "Subscription not found", code: "NOT_FOUND", recovery: "Call list_subscriptions() to find valid IDs"}'. Categorize as retryable, user-fixable, or fatal.
• Split 'computer_use' into focused tools (e.g., 'execute_script', 'click_element', 'type_text') with explicit parameters, validation, and security boundaries. Or document the exact action types and parameter schemas it accepts.
