improve_test_case

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden but only vaguely mentions 'optional automatic fixes' without detailing what changes are made, permissions required, or side effects. It doesn't specify if improvements are saved automatically, require review, or affect other test cases, leaving key behavioral traits unclear.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that front-loads the core purpose. It uses an emoji for visual emphasis but avoids unnecessary elaboration, though it could be slightly more structured by separating analysis from fixes.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 7 parameters, no annotations, and no output schema, the description is minimally adequate. It covers the basic purpose but lacks details on behavior, output format implications, or integration with sibling tools, leaving gaps in understanding how to effectively use it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema fully documents all 7 parameters. The description adds no additional meaning beyond what's in the schema, such as explaining how 'rulesFilePath' or 'checkpointsFilePath' influence analysis. Baseline 3 is appropriate since the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('analyze and improve') and resource ('test case'), with additional detail about providing 'detailed suggestions and optional automatic fixes'. It distinguishes from siblings like 'validate_test_case' or 'get_test_case_by_key' by focusing on enhancement rather than retrieval or validation, though it doesn't explicitly name alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives like 'validate_test_case' or 'get_enhanced_test_coverage_with_rules'. The description implies usage for test case improvement but lacks context on prerequisites, constraints, or specific scenarios where it's most appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
