update_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 of explaining behavioral traits. It does not disclose whether updates are partial or full replacement, how non-existing case IDs are handled, or any error/response behavior. The description is purely declarative with no transparency into side effects or limits.

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 sentence, but it is under-specified and does not earn its place. It adds no information beyond the tool name. This is under-specification rather than concise, valuable content.

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 with no annotations and no output schema, the description should explain update semantics, error conditions, and response handling. It provides none of this. The schema covers parameters but not behavioral context, leaving the tool significantly incomplete for an agent to invoke correctly.

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 description coverage is 100%, so the schema already fully documents each parameter (e.g., optional nature, priorities, automation ID). The description adds no extra parameter information. Baseline is 3 because the schema does the heavy lifting, and the description neither enhances nor contradicts it.

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 'Update a test case with new information' essentially restates the tool name 'update_test_case' without adding specific scope or behavioral detail. It does not mention which fields can be updated or how it differs from other tools. While it is a clear verb+resource, the lack of any additional context makes it tautological.

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 provides no guidance on when to use this tool versus alternatives such as creating a test run or getting test case details. There is no mention of prerequisites, typical use cases, or when not to use it. The sibling list is not leveraged to differentiate usage.

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