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

Annotations already declare readOnlyHint/openWorldHint, so the safety profile is covered. The description adds genuinely extra behavior beyond the annotations: the per-row output shape (HTTP code, inbound-link count, decoded labels) and the notConfigured:true fallback when no Bing Webmaster API key exists — useful edge-case disclosure.

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?

Two tight sentences, front-loaded with the core purpose and issue enumeration, then the fallback-state caveat. Every clause carries information; no padding.

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 an output schema present, return values needn't be restated. The description covers the resource, its issue taxonomy, and the missing-key edge case, so an agent has enough to call it correctly. The one omission is guidance on when to pick this over get_bing_crawl_stats.

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 coverage is 50%: limit is well documented in the schema, but siteUrl has no description. The description adds only a loose hint ('for a property') that maps to siteUrl, and does nothing to clarify the limit semantics already in the schema. Adequate but with a clear gap it does not compensate for.

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 ('URLs where Bing found crawl issues for a property') and enumerates the exact issue categories (4xx/5xx, redirects, robots.txt, DNS/timeout, malware) plus per-row fields. This detail naturally distinguishes it from the sibling get_bing_crawl_stats, which is aggregated counts rather than a per-URL list.

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 explicit when-to-use, when-not, or alternative is named. Usage is only implied by the resource itself, and the sibling get_bing_crawl_stats (closest alternative) is never referenced. The stated notConfigured prerequisite is the only contextual guidance.

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