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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds useful context by naming the returned fields (status code, response time, size, depth, indexable) and the 200-row window, but it does not explain ordering, how to reach older pages, or whether the window is a hard cap versus a page size.

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?

One tight sentence with the resource and scope front-loaded, plus a short constraint clause. Nothing is wasted, though 'Windowed at 200 rows' is slightly terse relative to the limit parameter's own 1-200 range.

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, the description carries the burden of describing returns; it partially does so by listing the columns but omits record shape, ordering guarantees, and how to page beyond the newest window. Adequate for a simple read tool, but gaps remain for an agent planning a multi-call crawl analysis.

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 100% for both site_id and limit, so the schema already carries the parameter semantics. The description mentions the 200-row window but adds no meaning beyond what the limit property already documents.

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+resource: retrieving page-level records from a site's most recent crawl. That distinguishes it from audit/issue siblings like get_site_audit and get_audit_issues, though it never names a sibling explicitly to sharpen the boundary.

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 when-to-use guidance, no prerequisites, and no mention of alternatives. 'Latest crawl' implies a scope but not a selection condition, so an agent must infer whether this or get_site_audit is the right call.

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