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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description does add two pieces of non-annotation context: it is free to call, and the data is a published (i.e. not real-time) snapshot. It says nothing about publication cadence, caching, or rate limits, so it clears the lowered bar without being rich.

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 sentence, front-loaded with the cost qualifier 'Free' and then the payload. The colon-delimited content list is dense but readable. Minor cost: the 'Free.' fragment is slightly clipped, but nothing is padded or redundant.

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 parameters, a full output schema, and complete annotations, the description only needs to say what the report is and what it contains — which it does. The remaining gap is not knowing how current 'latest published' is or whether the report is weekly-cadence fixed, a minor omission for a read-only report tool.

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 and the baseline of 4 applies. The description correctly avoids inventing parameter semantics that do not exist.

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 specific resource — the latest published weekly report — and enumerates its contents (venue payouts, worker wallets, honeypots, x402 index health), so an agent knows exactly what comes back. It stops short of distinguishing itself from the near-identical sibling 'settled_report', which is the one place confusion is most likely.

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 beyond the implicit 'you want the latest report'. With a similarly named sibling (settled_report) and adjacent tools like settled_events and settled_income_check, the description offers no routing rule or exclusion criteria to pick between them.

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