get_test_run_test_cases

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

Annotations declare it as read-only, idempotent, non-destructive, and open-world, which covers the safety profile. The description adds some context by specifying 'assigned to a specific test run', but doesn't disclose pagination, ordering, or potential latency. With annotations providing the core behavioral hints, a 3 is appropriate.

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 two sentences, front-loaded with the core purpose. The second sentence repeats the first with slightly more detail but doesn't introduce errors, making it efficient though slightly redundant.

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 the tool has one required parameter, no output schema, and annotations covering safety, the description is adequate but not thorough. It doesn't mention the return structure or whether test cases include metadata, which could help an agent interpret results, but the basic invocation is clear.

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?

The schema has 0% description coverage, but the description implies the parameter is a unique test run identifier, which aligns with the schema's 'testRunId'. However, it doesn't add format details or clarify that the parameter is nested under 'path', so it only partially compensates for the schema gap.

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 states a clear verb (Get) and resource (test cases for a test run), leaving no ambiguity about what the tool returns. However, it doesn't distinguish itself from related tools like get_test_case_test_runs or get_test_run_test_results beyond the resource name, which is a minor gap given the large sibling set.

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?

There is no guidance on when to use this tool versus alternatives. The description merely restates the operation without context on prerequisites, such as whether the test run must be open or exist, or when to prefer other test case retrieval tools.

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