Practical Utility
- warning:Usage examplesWhile the skill describes its capabilities, it lacks concrete, ready-to-use examples that demonstrate input, invocation, and observable output for each major function.
- warning:Edge casesThe skill mentions core competencies but does not explicitly document failure modes, their observable symptoms, or recovery steps for edge cases like malformed input or missing dependencies.
- warning:Production readinessWhile the skill outlines capabilities, it lacks concrete examples and detailed handling of edge cases, which are crucial for production readiness.
Code Execution
- warning:ValidationWhile the skill implies structured output for queries and code, there's no explicit mention or evidence of schema validation libraries being used for input or output sanitization.
- warning:Error HandlingThe skill description focuses on capabilities but does not detail how errors, unexpected states, or failure modes are caught, categorized, or reported meaningfully to the agent.
