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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety and locality are covered and the description need not repeat them. The description does add useful content scope by saying what the payload contains: the verdict categories, the signals, and overall health. It says nothing about whether this output is static documentation or computed live, or how large it is, which is the remaining behavioral gap.

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?

One sentence, front-loaded with the use case and followed by the concrete list of what the rules cover. Nothing is padded or repeated. The parenthetical enumeration is long but earns its place by naming the exact verdict values.

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 parameters, no output schema and full schema coverage, the description's job is mainly to say what reference material comes back, and it does that by naming verdicts, signals and overall health. An agent knows enough to call it correctly. What is missing is a note that this is static reference content rather than a query over items.

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 an empty object, so there is no parameter meaning to explain. Baseline of 4 applies; the description correctly makes no attempt to invent arguments.

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?

Names a clear action plus the resource: it exposes the rule set the coach uses, and it enumerates the verdict vocabulary (permanent / promising / temporary / trial / unproven / pending_removal) alongside signals and overall health. That is far more specific than its sibling getters, which return records rather than decision logic. It stops short of explicitly contrasting itself with a named sibling, so 4 rather than 5.

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 to see exactly how the coach decides item verdicts' does imply when to reach for it: when the agent needs the decision criteria rather than the data. But there is no when-not guidance, no statement that this returns static reference content rather than per-item results, and no pointer to the siblings that do return items. Usage is implied rather than spelled out.

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