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

Annotations already declare openWorldHint=true and readOnlyHint=false, and the description adds useful behavioral context: it operates on a 'bounded crawl sample,' checks ownership/version/expiry/membership 'when run,' and explicitly warns it does not cover every page. However it does not explain what task_id represents, whether a crawl must be started first, or what the output looks like, so disclosure is partial.

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?

Four short sentences, front-loaded with the scope and evidence statement, with no filler. The opening sentence redundantly restates the name, which is the only real waste.

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 and 0% parameter coverage, the description would need to explain what 'typed source evidence' and 'missing-field diagnostics' contain and how task_id/limit behave. Instead it stays at a high level, leaving an agent unable to call the tool confidently or anticipate results.

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% and neither parameter (task_id, limit) is mentioned in the description. An agent cannot learn from the description that task_id is a required crawl task handle or that limit caps results at 10 (maximum). The description does not compensate for the undocumented schema.

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 restates the name ('Website Page Checks from a bounded crawl sample') rather than stating a precise verb+resource, and it never clarifies what a 'check' actually inspects or how it differs from siblings like nexscope_website_audit_summary or nexscope_page_structured_data. The phrase 'Returns typed source evidence and missing-field diagnostics' adds some specificity, but the overall purpose remains abstract.

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 when-to-use guidance is given and no alternative tools are named despite a large set of related page/website siblings. The line 'This sample does not describe every page of a website' is a coverage caveat, not usage guidance; nothing tells an agent when to prefer this over the audit or page-analysis tools.

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