bing_list_sites

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is covered. The description adds the useful fact that each entry carries a verification status, but says nothing about authentication requirements against Bing Webmaster Tools or how many sites come back.

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 sentence with the resource front-loaded and no filler. Every clause (Bing Webmaster Tools + verification status) carries information the agent needs.

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 parameterless list tool with no output schema, telling the agent what the records contain (site + verification status) is adequate. However, nothing is said about auth requirements, result volume, or whether an empty list is possible, which are real gaps given openWorldHint=true.

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?

The schema has zero parameters at 100% coverage, so there is nothing for the description to disambiguate. Baseline 4 applies; no parameter semantics are needed or missing.

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?

Names a specific verb ("Lista") and resource ("los sitios de Bing Webmaster Tools") plus what is returned ("su estado de verificación"). The explicit "Bing" qualifier separates it from the sibling gsc_list_sites without needing to reference it by name.

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 never says when to call this versus the Google counterpart (gsc_list_sites) or when site data should be fetched another way. It offers no prerequisites, no ordering guidance, and no exclusions, leaving the agent to infer that this is a discovery entry point.

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