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

The description fully aligns with annotations (readOnly, openWorld, idempotent, non-destructive) and adds valuable behavioral details: the cost model (free default, BYO key for Anthropic), the return structure per model and combined, and the pass-through of the API key. No contradictions.

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 a single, well-structured paragraph of four sentences. It is front-loaded with the main purpose and covers all key aspects without unnecessary detail. Every sentence adds value, making it both concise and informative.

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?

Given the tool's moderate complexity (4 parameters, no output schema), the description adequately explains the core function, return format, and usage scenarios. It could briefly mention the nature of 'signals' in the response, but overall it provides sufficient context for an agent to use the tool appropriately.

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 description adds meaning beyond the input schema by explaining the default model and the purpose of the API key (passed through to Anthropic). Although schema coverage is 100%, the description enriches understanding by giving context about the models and pricing, which is not in the schema.

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 that the tool probes LLMs about an entity and scores visibility (0-100). It specifies the default model and optional Anthropic with BYO key, and lists use cases like AI-marketing audits and pre-launch brand checks. It distinguishes from sibling tools such as 'scan_competitor_ai_presence' by focusing on scoring visibility across models.

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 provides clear usage contexts (AI-marketing audits, pre-launch brand checks, competitive monitoring) and explains when to use the default vs. the Anthropic model. However, it does not explicitly compare to alternative tools or state when not to use this tool, missing an opportunity to guide agent decision-making.
