Single tool 'use_aws' has a reasonable description (194 chars, within baseline 34-392) and comprehensive parameter documentation. However, critical gaps undermine production readiness: (1) Output schema is completely undocumented, tool returns a string with no structure specification, forcing LLMs to parse unstructured text; (2) No error handling guidance, tool delegates to strands_tools but provides no recovery hints for common AWS CLI failures (invalid credentials, malformed commands, rate limits); (3) Parameters lack validation constraints, 'service_name' and 'operation_name' accept free-form strings with no enum or pattern, inviting hallucinated AWS service/operation names; (4) No pagination or result limiting despite AWS APIs often returning large datasets; (5) Security concern: profile_name parameter could be abused to access unintended AWS credentials if not validated server-side. Tool naming 'use_aws' is generic and does not follow verb_noun pattern (should be 'call_aws_api' or 'execute_aws_operation'). Parameter descriptions are adequate but lack format constraints (e.g., 'service_name must match AWS CLI service names like ec2, s3api, iam').

• Document output schema explicitly. Specify that the tool returns a string containing AWS CLI output, and provide examples of success vs. error responses. If possible, return structured JSON with fields like {status, output, error_message, suggestion}.
• Add error handling guidance to the tool description. Include recovery hints: 'If output indicates InvalidParameterValue, check parameter syntax against AWS CLI docs. If UnauthorizedOperation, verify AWS credentials and permissions.'
• Constrain 'service_name' and 'operation_name' parameters. Either enumerate valid AWS services (ec2, s3api, iam, lambda, etc.) or document the exact validation rules applied server-side.
• Rename tool from 'use_aws' to 'call_aws_api' or 'execute_aws_operation' to follow verb_noun pattern and clarify that this invokes AWS APIs, not just any AWS tool.
• Document profile_name validation and restrictions. Specify which AWS profiles are allowed, whether profile switching is restricted, and how credentials are injected securely server-side.
