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

No annotations are provided, so the description carries the full disclosure burden, yet it says nothing about whether the call is read-only, how many flags come back, whether results are scoped to a session or tenant, or what a 'flag' contains. The plural noun weakly implies a read-only list, which is the only behavioral signal present.

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?

It is short and front-loaded, but its brevity comes from under-specification rather than economy. The single fragment omits the verb and object that would give it meaning, so there is no wasted wording but also no useful lead.

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 zero annotations, no output schema, and no parameters, the description is the only source of context and it leaves the return shape, scope, and relationship to sibling tools entirely undefined. For a tool an agent would otherwise have to guess at, this is a substantial gap.

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 empty schema is fully self-describing, so there is nothing for the description to clarify. Baseline 4 applies for a no-parameter tool, with the caveat that no implicit scoping (e.g., which verdict set is consulted) is explained.

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 is a noun fragment ('Definition-diff flags for your verdicts') with no verb and no plain-language statement of what is retrieved. 'Definition-diff' and 'verdicts' are unexplained jargon, so an agent cannot tell whether this returns drift reports, rule changes, or something else, nor distinguish it from get_registry or classify_incident.

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 guidance, no statement of prerequisites, and no reference to the sibling tools get_registry or classify_incident. The phrase 'for your verdicts' faintly suggests it relates to prior classification output, but this is inference, not instruction.

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