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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds the default row cap (200) and the workspace-optional rule, but says nothing about ordering, whether results are per-site or per-workspace, rate limits, or how the issue list is aggregated in by_issue.

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?

It is front-loaded with the resource definition and the prioritization hint, which earns its place. However, the long enumeration of issue codes duplicates what the existing output schema already provides, making the block denser than necessary; the German text also sits oddly against otherwise English tooling.

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?

For a two-parameter, read-only report with an output schema present, most fundamentals are covered. The notable gaps are which site/domain is being reported on (only workspace is discussed) and whether the limit truncates silently or reports a total, which matters for an agent deciding how many calls to make.

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 burden and largely does: it states limit is the maximum number of rows with a default of 200, and that workspace is an optional customer-workspace slug when only one workspace exists. Both parameters get meaning the bare schema lacks; only the valid range/ceiling for limit is unstated.

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 identifies a specific resource: URLs on which Bingbot encountered problems, plus the exact issue categories returned (4xx, 5xx, robots-blocked, malware, DNS, timeout). That is far more concrete than a restatement of the name. It never names a sibling, though, so the boundary against bing_crawl_stats or bing_url_info must be inferred.

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 explicit when-to-use or when-not-to-use statement and no alternative is named. The one actionable cue is 'inbound_links ... hoch = zuerst beheben', which implies a prioritization workflow but leaves the choice against sibling tools (bing_crawl_stats, bing_url_info, dfs_onpage_crawl) to the agent.

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