check_coverage

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

No annotations are provided, so the description must carry the burden of behavioral disclosure. The description reveals nothing about what the tool does, what it returns, side effects, or prerequisites. It is completely opaque.

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 this is under-specification, not conciseness. It has only a tautological phrase that earns its place by no informative value. A description this short would be acceptable only if the name were self-explanatory, which it is not.

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?

Given the tool's complexity (13 parameters, nested objects, enums, no output schema, no annotations), the description is drastically incomplete. An agent lacks even the most basic understanding of what to pass or expect. This is far below the minimum viable definition.

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?

With 13 parameters, 2 required, and 0% schema description coverage, the description must compensate. It provides no information about any parameter, not even confirming which are required. An agent cannot infer the meaning of context, operation_id, or any other field.

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 is a tautology: "check coverage" merely restates the tool name. It does not specify what entity is being checked, what coverage means here, or any verb+resource structure. An agent has no idea what this tool actually does.

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?

There is zero guidance on when to use this tool versus its many siblings, such as check_coverage vs business_coverage_record or edge_validate. No context, alternatives, or exclusions are mentioned.

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