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

With no annotations, the description carries the full disclosure burden. It adds one useful behavioral trait: the résumé is not stored. It also points to an external service for a full check and rewrite, implying this tool is a limited comparison. However, it does not describe return format, rate limits, authentication, or what happens to the submitted résumé during processing.

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?

Two short sentences, with the core comparison stated first and the non-storage note second. There is no filler, though the external URL is slightly promotional. Overall the text is appropriately sized and front-loaded.

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?

No output schema exists, so the description should clarify what a comparison returns, but it does not. The family parameter is unexplained, and there is no indication of response format, limits, or how results should be interpreted. For a two-parameter tool with no annotations, this leaves important gaps.

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 50%: resume_text is documented in the schema, while the family enum has no description. The description says the résumé is not stored, which adds privacy meaning for resume_text, but it never mentions the family parameter or its allowed values. It therefore does not compensate for the missing parameter documentation.

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 verb and resource: compare résumé skills with Columbus, Ohio job postings. It is clearly distinct from the sibling tools, which handle data lookup, transcripts, QR codes, and page conversion. It does not explicitly frame the result as a gap analysis, but the core purpose is unambiguous.

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?

It explains what the tool does but gives no guidance on when to use it versus alternatives or prerequisites. There is no mention of when not to use it, what input is required, or what the tool is not suitable for. The external link suggests a fuller service exists, but does not help an agent choose this tool over anything else.

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