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

With no annotations the description carries the full burden, and it does disclose two real traits: execution is paid, and a completed run returns an RVO plus a signed Verification Receipt. However, it omits permissions/auth needs, what happens on unpaid or failed execution, and what 'RVO' actually is, leaving meaningful 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?

Only two sentences and front-loaded, but the 'R/IV ai.use.audit —' branding prefix consumes the prime opening slot without conveying meaning. Compact overall, yet the space is not fully earned.

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?

No output schema exists, so the description should explain return values, and it does so only cryptically ('RVO plus signed R/IV Verification Receipt'). For a no-param enterprise assurance tool with zero annotations, it leaves the agent without routing guidance or clear expectations about cost and 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?

The tool takes zero parameters, so the baseline is 4 and there is nothing for the description to clarify. No param-level information is expected or missing.

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 leans on branded jargon ('R/IV', 'RVO') and the abstract phrase 'evidence-verification primitive' rather than a concrete verb+resource. It never states what is being audited or how it differs from the many sibling verifiers (answer.audit, evidence.bundle, provenance.receipt, agent.action.verify). The name is essentially restated rather than explained.

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 explicit when-to-use, when-not-to-use, or alternative routing, which is critical given 30+ sibling audit/verify tools. 'For enterprise assurance' is the only hint of context and is too vague to guide selection over claim.check or citation.verify.

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