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

No annotations are provided, so the description carries the burden of behavioral disclosure. It does indicate a read operation and enumerates some returned content: steps signature, earnings/cost, and source record. However, it does not mention missing-case behavior, error semantics, or what 'signature of its steps' actually means.

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 one sentence, front-loaded with the primary action, and contains no filler. However, the trailing clause is tangled with repeated 'and' and uses unexplained jargon ('signature of its steps'), which hurts readability.

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 single-parameter, by-id lookup, the description provides the basic call purpose and a partial view of the return shape. But with no output schema and no annotations, it leaves unaddressed the meaning of 'signature,' what happens when a case is not found, and any relationship to list_cases.

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 schema has one required parameter, caseId, with no description and 0% coverage. The description's 'by its id' only restates what the parameter name already says and adds no details about the id's format, origin, or how to obtain valid case IDs.

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 states a specific action and resource: retrieving one case by its id. It is clearly distinct from list-oriented siblings like list_cases, and it previews what the result contains. The phrase 'signature of its steps' is somewhat cryptic but does not obscure the core purpose.

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 explicit when-to-use guidance or named alternatives are provided. The by-id phrasing implies this is for fetching a single known case, while list_cases would be used for collections, but that distinction is left to the agent to infer.

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