get_test_case

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It only states the action 'Get' (read), but does not mention potential errors (e.g., if ID not found), authentication requirements, or return format. For a simple getter, this is insufficient transparency.

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, concise sentence that is front-loaded with the verb and resource. It contains no redundant words or unnecessary details, earning a perfect score for conciseness and structure.

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 tool is a simple get-by-ID operation, and the schema fully documents the parameter. However, with no output schema or annotations, the description does not explain the return value or error behavior. It is adequate but leaves gaps that could affect an agent's confidence in using it 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%, with parameter 'case_id' clearly described as 'The ID of the test case'. The description's 'by ID' adds no new meaning beyond what the schema provides, so a 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 'Get a specific test case by ID' uses a specific verb ('Get') and resource ('test case') with a clear identifier ('by ID'). It clearly distinguishes from sibling tools such as list_test_cases (which lists multiple) and update_test_case (which modifies).

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 use when a single test case is needed by ID, but it does not explicitly state when to use this tool versus alternatives. No exclusions or alternative tool names are mentioned, leaving the usage context implicit.

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