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

With no annotations, the description must disclose behavioral traits. It fails to mention prerequisites (e.g., resume/job description being available), side effects, or the nature of the 'evidence-based' output. The tool is likely read-only, but this is not explicitly stated.

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, clear sentence that immediately conveys the tool's purpose. Every word is necessary, and there is no wasted space.

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?

Although an output schema exists, the description omits important context: how the resume and job description are 'uploaded' (likely via sibling tools), what constitutes 'evidence-based' coverage, and whether any preconditions must be met. This brevity leaves gaps for an AI agent.

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 zero parameters, so schema coverage is 100% by default. No parameter details are needed, matching the baseline score of 4 for no-parameter tools.

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 tool's function: comparing an uploaded resume and job description to return skill coverage. The verb 'compare' and noun phrase 'evidence-based skill coverage' are specific, and the tool is distinct from siblings like 'get_resume' or 'evaluate_answer'.

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 on when to use this tool or how it relates to siblings. For instance, it doesn't specify that the resume and job description must be uploaded first via other tools, nor does it indicate when this tool is appropriate versus 'evaluate_answer' or 'generate_interview_questions'.

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