Behavior1/5

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

No annotations are provided, so the description must carry the full burden of behavioral transparency. The one-sentence description discloses no behavioral traits: it does not mention authentication needs, page loading behavior, JavaScript execution, or any side effects. This is insufficient for a tool with 10 parameters.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise (one short sentence), but conciseness should not sacrifice usefulness. The single sentence does not provide enough information to be valuable, and it is not structured to convey key points. The description should be expanded to cover behavioral and parametric aspects.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (10 parameters, nested objects, and 18 sibling tools) and the absence of an output schema, the description is woefully incomplete. It fails to explain what the PDF output contains, how dynamic content is handled, or the effect of parameters like 'hideCookie' and 'skipCaptcha'. The description adds no context beyond the tool's name.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 30%, yet the description adds no information about any parameters. It does not explain the meaning of 'device', 'format', 'proxyCountry', 'margin', or other options. The nested object for margin is completely undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states 'Convert a URL to PDF', which is a clear verb+resource combination. However, it does not differentiate this tool from siblings like screenshot or webScrape, which also capture web content. The lack of scoping reduces clarity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. The sibling list includes tools for screenshots, web scraping, and performance audits, but the description gives no indication of when PDF conversion is preferred. There are no when-to-use or when-not-to-use instructions.

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