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

Annotations already establish the read-only, non-destructive, closed-world profile, and the description still adds substantive behavior: no assessment or charge is created, the limits are per-process and reset on restart rather than being remaining purchased quota, account-level limits still apply, and request keys count attempted unique operations including rejected ones but not reports or charges. That is genuinely non-obvious operational context an agent could not infer from the annotations.

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 content is front-loaded on usage, which is reasonable, but the text is a dense run-on with redundancy: 'does not order or charge' and 'No assessment or charge is created' say the same thing twice, and 'Account limits still apply' dangles without a referent. Several sentences could be tightened without losing information.

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 no output schema, the description must convey what comes back, and it largely does by listing the topics returned (permissions, environment, limits, pricing/quote paths). It does not describe the response shape or how the limit counters are presented, which is a minor gap for a zero-parameter informational tool.

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 tool takes zero parameters and the schema is empty, so there is no parameter semantics to clarify; baseline for a no-parameter tool is 4. Nothing in the description is needed or missing on this dimension.

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 enumerates the concrete resources it reports on (connection permissions, Live vs Sandbox, local request limits, pricing links, quote paths, paid-report requirements), so the agent knows exactly what this returns. It never names its siblings, but the repeated 'does not order or charge' / 'No assessment or charge is created' implicitly separates it from scanverity_request_assessment.

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?

'Use this when checking...' gives an explicit, itemized trigger list covering the main reasons an agent would call it. There is no explicit when-not statement or named alternative, but the negative scoping ('does not order or charge') steers the agent away from the ordering siblings.

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