test_cases_get

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

With no annotations, the description carries full responsibility. It only states a simple retrieval operation, omitting behavioral traits like idempotence, error handling (e.g., what happens if ID not found), or authentication requirements. This is insufficient for a safe read operation.

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 short but includes an extraneous line 'Tag: Test Cases' that does not clarify functionality. While the core sentence is concise, the unnecessary tag reduces efficiency and clarity.

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?

The description lacks essential context: it does not indicate what the response contains (e.g., full test case object), nor does it address error scenarios. Given no output schema, the description should provide more completeness about expected return or behavior.

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 a description for 'id'. The tool description reinforces that the ID is used to fetch the test case but adds no new semantic meaning beyond the schema. Baseline of 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 action ('Get') and the resource ('test case by ID'), distinguishing it from sibling tools like test_cases_list (returns multiple) or test_cases_create (creates). However, it could be more explicit about the scope or what fields are returned.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., test_cases_list, test_cases_archived_list). There are no usage conditions, prerequisites, or exclusions mentioned.

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