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

The description mentions 'No disk access,' which is a useful behavioral note, but it does not disclose how the other parameters are handled, what the tool returns, or any side effects. Since annotations are absent, the description carries the full burden, and it fails to explain the behavior for most of the schema fields.

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, but this is under-specification rather than efficient conciseness. For a tool with 9 parameters and no output schema, a one-sentence description is inadequate and fails to front-load essential information. The brevity is not earned because it leaves critical details out.

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 has 9 parameters, no output schema, and no annotations, the description is severely incomplete. It does not explain what the tool does with the majority of the parameters, what it returns, or how the parameters relate to the stated path-safety purpose. An agent would have no way to correctly invoke this tool for any of the non-path parameters.

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 is documented in the schema itself. The tool description adds no additional meaning about the parameters, so the baseline of 3 applies. It neither clarifies the relationship between the parameters nor provides any usage hints beyond 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 states 'Check whether a path looks safe' which is a specific verb and resource, but the input schema contains 9 unrelated parameters (ref, url, city, feed, host, json, zone, query, etc.), making the actual purpose ambiguous. It does not distinguish from sibling tools like browser-url-ok or validate-json, and the name suggests a narrow scope that the schema contradicts.

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?

There is no guidance on when to use this tool vs alternatives. The description provides no context about when it is appropriate, what it does with the non-path parameters, or how it relates to sibling tools. This is a complete absence of usage direction.

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