get_coverage

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states what the tool does (gets coverage) without revealing whether it is a read-only operation, any performance implications, or what the response format looks like. For a tool with zero parameters and no output schema, this is a notable gap.

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, well-formed sentence that front-loads the action and scope. It contains no extraneous words and is immediately understandable.

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 tool with no parameters and no output schema, the description provides a minimal but sufficient idea of the tool's purpose. However, it does not clarify what 'coverage' means in terms of output structure, such as whether it returns counts, percentages, or per-framework breakdowns. An agent might need more detail to interpret the result 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?

The input schema has 0 parameters, so the baseline is 4. The description does not need to explain parameters, and it correctly omits any parameter-specific information. This score reflects the absence of parameter complexity rather than any descriptive effort.

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 verb 'Get', the resource 'component availability coverage', and the scope 'across all frameworks'. This differentiates it from sibling tools like list_components (which lists components) and get_component (which fetches a specific component) by focusing on coverage metrics.

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 that this tool is used when coverage data is needed, but it does not explicitly state when to prefer it over alternatives or mention any exclusion criteria. No alternatives are referenced, leaving the agent to infer the appropriate context from the tool's purpose.

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