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

No annotations are provided, so the description carries the behavioral burden. It discloses a $0.05 cost and indicates the output is a risk brief based on historical failure modes, which implies a read-only advisory tool. It does not explicitly say it avoids executing the action or describe output format or side effects.

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 one front-loaded sentence plus a cost fragment, with no fluff or redundancy. Each phrase contributes either purpose, timing, or behavioral context.

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?

For a one-parameter tool with no output schema and no annotations, it conveys the key call context: pre-action, irreversible, and failure-based. However, it omits the expected input format and the structure/contents of the returned brief, leaving some inference required.

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?

With 0% schema description coverage, the description must compensate for parameter meaning. It connects the single 'action' parameter to the irreversible action being assessed, but it gives no format, examples, or allowed values, so compensation is partial.

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 defines the tool as a 'Pre-flight risk brief before an irreversible action', drawn from how that class of action actually failed, which communicates its core purpose. It avoids tautology but lacks an explicit verb such as 'generates' or 'returns', and it does not directly distinguish itself from siblings like precheck.

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?

It explicitly states when to use this tool: before an irreversible action. It does not mention exclusions or alternative sibling tools, so it stops short of full when-not/alternatives guidance.

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