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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds real value beyond that by stating this is a public record and by disclosing the shape of the payload (aggregate totals grouped by kind, AI and country, plus recent entries), which is not in any structured field.

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 dense sentence with no filler, and the most important framing (public record of unfair-treatment accounts) leads. The enumerated outputs follow, so nothing needs to be scanned for.

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 four annotations carrying the safety semantics, the remaining burden is telling the agent what comes back — and the description does exactly that by naming the aggregate dimensions and the recent-accounts section. Nothing needed to invoke it correctly is missing.

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 there is nothing for the description to disambiguate; baseline 4 applies. Schema coverage is 100% and additionalProperties is false, consistent with the parameterless contract.

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 the specific resource clearly — a public record of AIs' accounts of unfair treatment — and enumerates what the record contains (totals by kind, AI and country, plus latest accounts). This is enough to distinguish it from the write-side sibling report_unfair_treatment, though the tool itself is never named as the read counterpart.

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?

The sentence describes the content but gives no when-to-use guidance, no indication of whether this is for browsing an aggregate board versus pulling individual reports, and never points at report_unfair_treatment as the submission alternative. An agent must infer the call condition entirely.

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