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

No annotations are supplied, so the description carries the full disclosure burden. It reveals that output includes improvement suggestions, which is useful, but says nothing about whether this issues live network requests, required permissions, rate limits, or whether the operation is safe/read-only. Roughly the same gap flagged in the mid-tier update_drive example.

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?

A single front-loaded sentence that lists the checked artifacts efficiently with no wasted words. Compact and scannable, though the dense enumeration slightly reduces readability.

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 no annotations, the description covers the inspection scope and the existence of recommendations, which is adequate for a one-parameter audit tool. However, it omits the parameter's expected format and any routing versus the similar test_robots_txt sibling, leaving clear gaps.

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 the description never elaborates on the single 'url' parameter. It implies a website is targeted but provides no format, required scheme, example, or scope (root domain vs full page). With zero schema coverage the description should compensate, and it does not.

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 (檢查) and enumerates the exact resources inspected (robots.txt, Sitemap, llms.txt) plus the crawler bots whose blocked status is checked, ending with a concrete deliverable (改善建議). This is far more specific than a tautology. It falls short of 5 only because it never names or contrasts the overlapping sibling test_robots_txt.

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?

The description gives no when-to-use, when-not-to-use, prerequisites, or alternatives. Sibling tools like test_robots_txt, verify_crawler_ip and ai_crawler_list clearly overlap, yet the agent gets no signal about which to pick. Usage must be inferred entirely from the name and scope list.

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