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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does mention 'No disk access', which is a useful safety trait, but it fails to explain what 'looks safe' means, what the return format is, whether it returns a boolean, or how it behaves for the other 8 parameters. The behavior for most of the tool's surface area is completely undisclosed.

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 extremely short (two sentences), which is concise, but it under-specifies the tool's actual scope. It front-loads the path check but ignores the other parameters, making the description unhelpful. Every sentence could be retained, but the content is incomplete, so it fails the 'earn its place' test because it misleads by omission.

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 complexity of 9 parameters, no output schema, and no annotations, the description is severely inadequate. It only addresses one parameter and provides no information on return values, error behavior, or the purpose of the remaining parameters. An agent cannot correctly invoke this tool for anything other than the path parameter, and even that is ambiguous.

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 schema has 100% description coverage, so each parameter has a basic description. The tool description adds no extra meaning for the parameters beyond the path one, and even for that it only restates 'no disk access'. Since the schema already documents all parameters, the baseline is 3. The description does not help clarify the role of the unrelated parameters, but it doesn't actively contradict them either.

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 states a specific action ('Check whether a path looks safe') but it only covers the 'path' parameter. The input schema includes 8 other unrelated parameters (ref, url, city, feed, host, json, zone, query), suggesting the tool is a generic shape-checker, yet the description does not mention these. The purpose is unclear and potentially misleading, as it doesn't distinguish what this tool does for the other parameters or how it differs from sibling shape-check tools like 'browser-url-ok' or 'figma-url-shape'.

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 is provided on when to use this tool versus alternatives. The description contains no mention of context, conditions, or exclusions. It does not reference any sibling tool or explain the appropriate scenarios for checking a path versus other shape checks. Agents receive no help selecting this tool from the large sibling list.

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