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

Adds real context beyond annotations: a fixed bounded plan (implying bounded crawl scope/cost), observation timestamps retained on source and image facts, and an explicit statement of what the output does NOT prove (current indexing or full site coverage). This is exactly the kind of caveat an agent needs to avoid over-claiming. It stops short of stating auth needs, runtime, or failure modes.

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 with no filler, which is good, but the lead sentence is vague phrasing ("explicit observation scope and missing evidence") rather than a concrete statement of function. The most useful content, the bounded plan and evidence caveats, is not 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?

With no output schema, two undocumented parameters, and openWorldHint=true, the description should say what the summary contains and how BASE vs ENRICHED differ. As written, an agent cannot predict the response shape or the cost/scope tradeoff of the profile flag.

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 0%, so the description must carry parameter meaning and it does not. The required "target" is never described (URL format? domain only? max 253 chars), and the BASE/ENRICHED enum — the single most consequential choice for cost and richness — is completely unexplained.

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?

"Website audit summary" restates the name/title and the two follow-up sentences describe caveats about evidence rather than what the audit actually covers (pages, links, resources, SEO signals). There is no differentiation from closely related siblings such as nexscope_website_page_checks, nexscope_page_lighthouse, or nexscope_seo_page_evidence. The agent knows roughly the domain but not the exact deliverable.

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 statement of when to pick this over the many other website/SEO tools in the sibling list, and no prerequisites (e.g., a resolvable URL). The line about screenshots not proving current indexing is interpretive guidance for reading results, not selection guidance for invoking the tool.

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