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

With no annotations provided, the description carries the burden of explaining behavior. It discloses what the tool returns: organic results with title, URL, snippet, displayed URL, position, related searches, answer boxes/knowledge panels, and pagination metadata. It does not mention rate limits, authentication, or error behavior, but for a read-only search fetch the disclosed behavior is reasonably complete.

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?

The description is compact and front-loaded, starting with the tool's core purpose and then covering capabilities, return values, and use cases without redundancy. Every sentence adds value, and the structure is easy for an agent to parse quickly.

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 tool with 11 parameters and no output schema, the description does well by summarizing return fields and listing all major parameter groups. It does not detail exact response structures or edge cases, but the combination of full schema coverage and the return-value overview gives an agent enough context to select and invoke the tool correctly.

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%, so the schema already documents every parameter individually. The description adds grouping context (e.g., 'geo targeting (location/lat/lon), market (mkt), country (cc)') but does not introduce semantic detail beyond the schema. Baseline 3 is appropriate.

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 clearly states 'Fetches Bing SERPs for a query' with a specific verb and resource, and enumerates the key capabilities like geo targeting, market, safesearch, and pagination. It also names concrete use cases (SEO rank tracking, Bing-specific visibility audits), making it easy to distinguish from the many sibling search tools for Google, DuckDuckGo, and other engines.

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 clear application contexts: 'Use for SEO rank tracking, SERP feature monitoring, Bing-specific visibility audits, and training/eval data for search agents.' This implies when to choose Bing SERP over alternatives, though it does not explicitly name sibling tools or state when not to use it.

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