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

With no annotations, the description carries the full burden of behavioral disclosure. It states the settlement requirement but does not explain what the review does, whether it is publicly visible, whether it affects agent reputation, or whether the action is reversible. For a mutating review action, this is a significant transparency 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?

Two short sentences efficiently convey the core action and the key eligibility rule. The critical constraint about the settlement amount is front-loaded. It loses one point because it leaves out parameter-related context that would be valuable near the top.

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 output schema and no annotations, the description should explain more about how the review is recorded, what the rating values mean, and how transferId relates to the settlement. The description only covers the minimum payment requirement and leaves several operational details unspecified.

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?

Schema description coverage is 0%, and the description only hints at the settlement concept without explicitly mapping it to the transferId parameter. It does not explain what subject, reviewer, or rating semantically refer to, beyond the obvious review context. The description does not compensate for the missing schema documentation.

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 states a clear verb and resource: 'Review an agent you paid', and adds a distinguishing requirement that the review must be backed by a settlement of at least 0.01 USDC. This helps separate it from generic agent operations like call_agent or register_agent. However, it does not explicitly name a sibling or contrast itself with related tools like agent_reputation or pay_agent.

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 description implies the tool should be used after paying an agent and only when a settlement proof exists. The 0.01 USDC minimum gives a concrete eligibility condition. It does not provide any when-not-to-use guidance or mention alternative tools, leaving some routing ambiguity.

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