get_test_case_collection

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is fully covered. The description adds that results can be filtered/sorted/paginated and that relations can be expanded, which is useful but shallow; it does not disclose default page limits, default relation behavior, or result shape.

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?

Front-loads the core action and then enumerates capabilities in three short sentences with no filler. The first two sentences ('Get all test cases.' / 'Retrieve all test cases from a project.') are near-duplicates, a minor redundancy that costs the top score.

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 complex filtered-list endpoint with a ~25-option nested filter object, the description covers project scoping, folder filtering, generic filtering/sorting/pagination, and relation expansion. Combined with the richly documented nested schema and read-only annotations, and given no output schema exists, nothing essential for correct invocation is missing.

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?

Top-level schema coverage is 0% (the single 'query' object has no description), but its nested properties are densely documented with per-field descriptions and an enum for 'with' and 'order'. The description touches the key concepts (folder identifier, filters, sorting, pagination, relations) but adds no syntax, defaults, or formats beyond what the nested schema already provides.

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?

States a specific verb and resource: 'Get all test cases. Retrieve all test cases from a project.' An agent knows this is the project-scoped collection endpoint. It does not, however, distinguish itself from the sibling get_test_case (singular) or explain why one would list rather than fetch one directly.

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 by naming three mechanisms (folder identifier, custom filters/sorting/pagination, relations), which tells the agent what can be done. It offers no explicit when-to-use vs alternatives, no prerequisites, and no exclusions, so routing guidance remains implicit.

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