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

No annotations provided, so description carries full burden. It discloses cost ($0.01 USDC) and methods, but does not state whether the tool fetches the URL (potential side effects), what the output format is, or if it is read-only. Significant behavioral gaps.

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?

Single sentence front-loads cost and methods, with comparative statement. No waste; efficient and to the point.

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 this is a paid tool with no output schema, the description lacks details on what the tool returns (e.g., a boolean, score, or report). Also does not explain when to use this over other siblings besides linkrisk. Incomplete for a tool that costs money.

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 0% (no description on the 'url' parameter). The description only implies the parameter is a URL via 'URL safety check'. While the parameter is self-explanatory, the description adds minimal additional meaning beyond the parameter name.

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 it is a 'definitive URL safety check' using specific methods (Playwright sandbox, VirusTotal, redirect tracing) and distinguishes from sibling 'linkrisk' by claiming 'More thorough than linkrisk'. Verb+resource+scope well-defined.

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?

Provides clear context by stating 'More thorough than linkrisk', implying this tool should be used when a more thorough check is needed. However, lacks explicit when-not-to-use or other alternatives beyond linkrisk.

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