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

Description adds context beyond annotations by mentioning 'Claude grounded by web search' and '0 ScrapeCreators credits', indicating read-only nature and cost. 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?

Description is concise and front-loaded, but could benefit from slightly more structure (e.g., separate lines for modes).

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?

Output schema exists, reducing need for return value description. However, description could mention output format or include more usage context.

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 coverage is 100%, and description adds value by explaining enum values for mode with concrete examples, while domain is straightforward.

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?

Description clearly states the tool discovers competitor brands from a domain, with explicit modes. It distinguishes itself from siblings by focusing on competitor discovery via web search.

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?

Description explains modes and default behavior but does not provide explicit guidance on when to use this tool versus sibling tools like competitor_teardown or search tools.

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