Two simple tools with minimal documentation. Both have valid input schemas with typed parameters and descriptions, but tool descriptions are extremely brief (16-34 chars, well below the 50-200 char baseline for LLM-optimized descriptions). No output schemas documented. No error handling guidance. No parameter constraints (enums, ranges, formats). Naming is acceptable but generic. No composition or chaining support evident.

• Expand tool descriptions to 50-200 chars. Example: 'add: Adds two integers and returns their sum. Use for arithmetic operations. Returns an integer result. Parameters a and b must be valid integers.'
• Document output schemas explicitly. Declare that both tools return type 'integer' with a description of the result (e.g., 'The sum of a and b' for add).
• Add parameter constraints: specify min/max for a and b (e.g., -2^31 to 2^31-1 for 32-bit integers, or document your actual limits).
• Implement error handling: catch overflow, type errors, and return actionable messages like 'Invalid input: a and b must be integers. Got a={value}, b={value}.'
• Rename tools to verb_noun style: 'add_numbers' and 'multiply_numbers' for clarity and consistency with production baselines.
