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

Without annotations, the description must convey behavior. It notes 'No disk access' but omits return values, error behavior, side effects, or what constitutes a 'safe' path. This leaves significant 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?

The description is very short and free of fluff, which is positive. It lacks structure (e.g., no mention of parameters or behavior domains), but the brevity itself is not problematic.

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 9 parameters, no output schema, and no annotations, the description is severely incomplete. It does not explain how the parameters interact, what the tool returns, or how to interpret results.

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?

All 9 parameters have schema descriptions, so coverage is complete. However, the description itself adds no extra meaning beyond the schema, and several parameters seem unrelated to the tool's purpose (e.g., 'query', 'zone').

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') and identifies the resource ('path'), but does not clarify what 'safe' means or the tool's broader purpose. It is clear enough for basic intent but lacks depth.

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, prerequisites, or how it relates to sibling tools. The description gives no context for selection or invocation.

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