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

With annotations already covering the read-only and non-destructive profile, the description adds meaningful context beyond them: results come from a bounded sample, output includes typed evidence plus diagnostics for missing fields, and source ownership/version/expiry/membership are validated at run time (implying entitlement failures are possible). It stops short of describing pagination or result volume behavior.

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 resource and scope, and each sentence contributes something (output shape, runtime checks, coverage caveat). Minor boilerplate in the entitlement sentence but no 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?

Safety and coverage context is decent and no output schema is needed, but with three undocumented parameters at 0% schema coverage the definition leaves the agent unclear on how to obtain task_id and how to page through results. It is adequate but has a clear, actionable gap for a tool that requires an opaque task identifier.

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 carries the full burden, yet it never mentions task_id, limit, or offset. Nothing explains where task_id comes from or that limit/offset drive pagination over the sample, leaving the required parameter's meaning entirely implicit.

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 states a concrete resource (website links) and an explicit scope (a bounded crawl sample), and it clarifies the output shape with 'typed source evidence and missing-field diagnostics'. It does not, however, distinguish this tool from nearby siblings such as nexscope_website_page_checks, nexscope_website_resource_status or nexscope_website_redirect_chains, so an agent still has to guess which website tool to pick.

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?

There is no guidance on when to call this rather than a sibling, and no prerequisites or exclusions are named. The only usage-adjacent statement is a limitation ('This sample does not describe every page of a website'), which describes coverage, not tool selection.

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