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

Only behavioral note is 'no disk access'; no mention of return values, errors, or what happens with invalid paths, and no annotations exist to fill the gap.

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 short and front-loaded, but the brevity omits essential context; still, it is not padded or disorganized.

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?

With nine optional parameters, no output schema, and no usage/return details, the description is far too thin for an agent to call this tool confidently.

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 descriptions are present but most are unrelated to path safety (ref, url, city, feed, host, json, zone, query) and the description does not explain their role; only 'path' is clarified.

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 it checks whether a path looks safe, but 'safe' is undefined and the schema exposes nine unrelated parameters; it does not clearly distinguish this shape check from sibling URL/query tools.

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?

No guidance on when to use this instead of similar validators, what inputs are expected, or what conditions make a path unsafe.

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