Single tool 'grill_with_form' has a well-structured JSON Schema with comprehensive parameter definitions, clear descriptions, and proper type constraints. The tool description is detailed (280+ chars) and explains the use case, mandatory questions, and optional 'Other' field behavior. Input schema includes nested object definitions for questions and choices with required fields and descriptions. However, output schema is not documented in the visible code, the tool returns an Outcome but the structure of answers is not formally specified. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) are present. Error handling and recovery guidance are not visible in the tool definition itself.

• Document the output schema explicitly. Define the structure of the Outcome object and the answers map (e.g., {answers: {[questionId]: string | string[]}, kind: 'submitted' | 'abandoned' | 'timeout'}).
• Add tool annotations: mark as readOnlyHint=false (it collects user input), destructiveHint=false (no data destruction), idempotentHint=false (user input is non-deterministic).
• Add error handling documentation to the tool description: 'Returns abandoned if user closes tab or timeout expires. Returns submitted with answers if all questions answered. All questions are mandatory.'
• Rename tool to 'present_form' or 'collect_form_answers' for clearer verb-first naming that immediately signals the action to LLMs.
• Document the 'choices' array structure more explicitly: clarify that description is optional per choice, and that empty choices array means free-text-only question.
