Audit a public page

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

Annotations already declare read-only, idempotent, open-world, non-destructive, so the safety profile is covered. The description adds genuinely useful behavior beyond that: server-delivered HTML only, no JavaScript execution (so client-rendered content is invisible), and the explicit exclusions of vendor impersonation and citation prediction.

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?

Three short sentences, zero filler, and the core action (fetch + audit a public page) is front-loaded. Every clause carries information the agent needs.

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 single-parameter read-only tool with no output schema, the description does the right work: it summarizes the return shape (evidence, scored checks, unknowns, prioritized fixes) and bounds the analysis. It could say more about failure modes for non-public or JS-rendered pages, but nothing critical is missing.

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 description adds the meaningful qualifier that the target must be 'one public page', but says nothing about URL format, length limits, or whether redirects/query strings are accepted. With only one parameter and 0% schema description coverage, the schema's uri format and maxLength carry the remaining semantics.

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?

States a specific verb and resource: fetch one public page and audit server-delivered HTML. The 'fetch' framing implicitly distinguishes it from the sibling audit_html (which presumably audits supplied markup), but no sibling is named explicitly, so the differentiation is left to inference.

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?

Usage is implied rather than stated: this is the tool for auditing a live public URL. There is no explicit when-to-use/when-not guidance, no mention of when to prefer audit_html or compare_audits, and the 'no JavaScript execution' line is a capability limit rather than routing advice.

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