This server exposes 4 tools via AWS Bedrock AgentCore, but critical definition elements are missing or severely underdeveloped. Tool names follow verb_noun convention (get*), which is good. However, descriptions are generic and lack actionable context for LLM selection. Most critically: NO input schemas are visible in the source code for 3 of 4 tools. Only getUserFoodPreferences shows a partial schema (season parameter). Parameter descriptions are absent or trivial. Output schemas are completely undocumented. Error handling guidance is missing. The codebase shows infrastructure (Dockerfile, CDK, Flask backend) but does NOT expose the actual tool definitions, schemas, or implementation details needed for evaluation. Tool definitions appear to be generated or registered dynamically by the Bedrock AgentCore framework, making them impossible to verify from static code analysis.

• Add explicit input schemas to all tools in the MCP tool registration. For getUserProfileComplete, document required/optional parameters (e.g. user_id: string, include_conversations: boolean). Use JSON Schema with type and description for each parameter.
• Expand tool descriptions to 150-250 characters. Example: 'Retrieve complete user profile including identity, account status, conversation history, and food preferences. Use this when you need comprehensive user context; use getUserBasicInfo for quick identity lookups only.'
• Document output schemas for each tool. E.g. getUserProfileComplete returns {user_id, name, email, account_status, conversation_count, food_preferences: []}. Include field types and whether fields are always present or conditional.
• Add parameter descriptions. For getUserFoodPreferences, document: 'season (optional): Filter preferences by season (spring|summer|fall|winter). If omitted, returns all-season preferences.'
• Implement error handling with recovery guidance. E.g. 'User not found. Try search_users() with a partial name, or verify the user_id is correct.'

Inferred effective spec: 2026-07-28+.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
