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

With readOnlyHint=true and openWorldHint=false already declaring the safety profile, the description still adds real context: the answers are grounded in FAQ sections of guides/statistics pages, and each result carries its source URL. That grounding scope and the return shape are useful disclosures beyond the annotations.

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 action and corpus, followed by the return-content note. No filler or restatement of the title.

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?

There is no output schema, and the description does cover the essential return shape (answers plus source URL). However, it leaves the 'limit' parameter entirely unexplained and gives no sense of answer volume or ranking behavior, which a retrieval tool of this kind should clarify.

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% for both parameters. The 'question' parameter is self-evident, but 'limit' (default 3, max 8) is undocumented in both schema and description, so the agent has no guidance on result-count control. The description compensates for neither.

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: finding closest published answers to a B2B GTM question, and pins the corpus to FAQ sections of guides and statistics pages. It implicitly separates itself from search_guides/search_statistics by returning synthesized answers rather than raw pages, but it never names those siblings explicitly.

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 implies usage (use it when you have a GTM question you want a direct answer to) but gives no explicit when-to-use vs. search_guides or search_statistics, and no exclusions or prerequisites. An agent must infer the routing decision itself.

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