list_test_sets

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

No annotations provided, and the description only adds that test sets contain scenarios. It does not disclose pagination behavior, rate limits, or response structure, which is insufficient for a listing tool.

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 concise sentences. The first defines the tool, the second adds a practical usage hint. No extraneous information, well structured.

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 no output schema and 4 optional parameters, the description is incomplete. It does not specify what fields are returned, how filter works, or how to use pagination tokens, leaving the agent underinformed.

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 coverage is 100% with descriptions for all 4 parameters. The description adds no additional parameter-level meaning, so baseline 3 is appropriate.

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 tool's purpose: listing test sets (collections of test cases). It distinguishes from siblings by mentioning test_set_id usage in runs, which is unique among sibling tools.

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?

Provides a hint about using test_set_id when creating runs, but lacks explicit guidance on when to use this tool vs alternatives like list_test_cases, or context on filtering and pagination.

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