get_test_case

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

No annotations are provided, so the description carries the full burden. It mentions the output includes 'parameters, request body, and assertions', which gives some idea of the return content, but it does not state that the operation is read-only (though likely), what happens if the test case ID does not exist, or any authentication or access requirements.

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, well-structured sentence that immediately states the tool's purpose. It is front-loaded with the action and resource, and includes important specifics about the output. No unnecessary words.

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?

Given only one parameter and no output schema, the description provides a reasonable level of completeness by listing the key components of the returned details. However, for a tool returning potentially complex data, a more detailed list of output fields or structure would enhance completeness.

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?

With 100% schema description coverage, the single parameter 'testCaseId' is already well-documented in the schema. The description adds no additional semantic meaning beyond 'by its ID', leaving the baseline score at 3.

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 specifies the action ('Get full details'), the resource ('single test case'), and the identifier ('by its ID'). It also lists what is included (parameters, request body, assertions), distinguishing it from sibling tools like list_test_cases which returns multiple test cases without full details.

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?

The description implies usage for retrieving details of one test case given its ID, but provides no explicit guidance on when not to use it or alternatives. For example, it could mention that for listing all test cases, use list_test_cases instead.

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