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

No annotations are provided, so the description carries the burden. It usefully discloses the paid x402 USDC cost/chain and the local signals it inspects, and 'Score + fixes' hints at output, but it does not state read-only/safety behavior, rate limits, failure modes, or detailed return format.

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 dense but informative sentence, front-loading the paid-call notice before enumerating the local-presence checks. It could be more scannable, but every clause adds useful signal.

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 one-parameter paid SEO report with no output schema, the description covers payment and the kinds of local signals inspected. However, the scoring scale, fix format, and returned data structure are unspecified, leaving meaningful gaps for an agent interpreting the result.

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?

There is one parameter with 100% schema description coverage, and the schema already defines it as a public page URL or domain. The description adds no additional URL constraints or syntax beyond 'from the website', so the schema does the heavy lifting.

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 scope: local SEO/listings readiness signals from a website, including phone, address, JSON-LD, Maps/reviews, social profiles, plus score and fixes. This clearly distinguishes it from generic SEO audit siblings by local-presence focus, though it does not explicitly name those alternatives.

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 by 'local SEO / listings readiness' and the listed local signals, but there is no explicit when-to-use/when-not guidance or routing versus siblings like seo_full_audit, seo_technical_audit, or seo_keywords_content.

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