set-test-case-relations

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

The description highlights the key behavioral trait of replacing all existing relations, which is critical. However, with no annotations provided, it misses details such as side effects, authorization requirements, what happens with an empty relation array, or idempotency. The description carries the full burden but is not exhaustive.

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 action and behavior, and includes a concise list of types. Every word is necessary, and there is no redundancy or fluff.

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 mutation tool without an output schema, the description covers the essential behavior (set and replace) and valid input types. It could mention prerequisites (e.g., test case existence) or error handling, but given the simplicity, it is fairly complete.

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 input schema already covers 100% of parameters with descriptions, so the baseline is 3. The description adds the 'replaces all existing' context but does not provide new parameter-level semantics beyond what the schema offers. The listed types are already in the schema enum.

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 verb 'Set relations' and the resource 'test case', with the specific behavior 'replaces all existing'. It lists the allowed relation types, distinguishing this from the read-only sibling tool 'get-test-case-relations' and other set 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?

The description implies the tool is used to update relations with a full replacement model, but it does not explicitly mention when to use it versus alternatives like 'get-test-case-relations' to first view existing relations. The clarity of 'replaces all existing' provides some context, but no explicit when-not or alternative guidance.

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