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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so safety/idempotency behavior is covered structurally. The description contributes the gate taxonomy and the three-valued verdict vocabulary (publish/caution/abstain), which is genuinely useful behavioral context, but it says nothing about preconditions, what the caller must supply for the gates to resolve, or what an abstain verdict implies.

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?

A single front-loaded sentence with no filler or repetition, ending on the concrete outcomes. It is dense but every clause carries content; the only cost is that terseness makes it opaque rather than wasteful.

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?

An output schema exists, so return values need not be described, but a 10-parameter gate-evaluation tool with 0% schema coverage needs far more than one clause about which gates run. Missing are the meaning of the inputs, the required claim format, and any routing against the sibling audit/readiness tools. The description is insufficient for correct invocation even though the verdict vocabulary is present.

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?

Schema description coverage is 0% across 10 parameters, so the description carries the full burden and mostly fails it. The gate names hint at a few inputs (calculation→calculationCertified, approved-rule→approvedRules, opposition→opposingEvidence, harm→harmClass), but format, optionality, and the roles of claimClass, nearBoundary, unresolvedSourceKeys and supportingEvidence are never explained. With 0% coverage a 2 is generous but the implicit mapping does add a little signal.

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 names a concrete mechanism (five named gates) and concrete outputs (publish, caution or abstain), which tells an agent roughly what happens. However, it never states the resource being audited (a single prediction claim) or how it differs from the many adjacent audit/assess siblings such as audit_reading_evidence, audit_chart_calculation and assess_prediction_readiness. Purpose is inferable but not sharply differentiated.

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 when-to-use, when-not-to-use, or alternative-tool guidance anywhere in the description. Given the sibling list contains at least three other auditing/readiness tools, an agent has no stated signal for choosing audit_prediction_claim over them. Nothing in the text is misleading, but no routing help is offered.

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