The Cure Protocol

check_evidence_gate

Read-only

CHECK THE PUBLICATION GATE for a set of evidence claims: verified or preliminary, and which claims keep it preliminary. Preliminary is fine to publish when labelled.

Input Schema

Name	Required	Description	Default
`ids`	Yes	Comma-separated claim ids.

Output Schema

Name	Required	Description	Default
`data`	No	The answer. Shape depends on the tool; describe_tool documents it.
`_meta`	No	source, generatedAt, sources (per-source lastSyncedAt and ageHours), rateLimit, disclaimer.

A3.5/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds a genuine business rule about preliminary claims being publishable when labelled, but says nothing about cost, failure modes on unknown ids, or what the gate actually inspects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded with the action and outcome, with the policy caveat last. Minor capitalisation noise aside, every clause carries information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present and annotations covering safety, the description need only frame the decision the tool supports, which it does. Remaining gaps concern error behavior and next steps after a preliminary verdict, both minor.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Only one parameter ('ids') with 100% schema description coverage, so the schema carries the burden and baseline 3 applies. The description adds no detail on id format, batch limits, or behavior on unresolvable ids.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('check the publication gate') plus the two possible outcomes (verified / preliminary) and the diagnostic it returns (which claims keep it preliminary). This is clear enough to distinguish it from list_claims or find_evidence_contradictions, though it never names a sibling to sharpen that boundary.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Preliminary is fine to publish when labelled' implies when the result matters, but that is a policy on the outcome, not a rule for choosing this tool over alternatives. No exclusions or prerequisites are stated, so the agent must infer the call context.

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