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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds only that payment outcome is included, which is a small content hint; it says nothing about what happens with an unknown address or collectionId, whether review can be pending, or how fresh the verdict is for an openWorld server with no stored key.

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 tight sentence with no filler and the payoff detail placed after the verdict, which is a sensible ordering. It is concise to the point of being thin, but no sentence is wasted.

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?

There is no output schema, so the description should describe what a verdict looks like, what states exist, and what the money-status field can be. It is instead a fragment that leaves the return shape and the sibling boundary with review_billing_status entirely undefined.

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 coverage is 50%: address is well documented in-schema, but collectionId has no description anywhere, and the tool description never mentions either parameter or how they scope the lookup. With half the parameters undocumented, the description needed to compensate and does not.

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 identifies the subject as the review decision on an answer plus its payout outcome, which is more specific than the title alone. But it is a noun phrase with no verb and no indication that this is a retrieval operation, and it does not distinguish itself from siblings like review_billing_status, which also sounds like it covers money status.

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 at all: nothing says to call this after collect_answer, nothing explains how it differs from review_billing_status or list_checkers, and no prerequisites are given. An agent must guess from the sibling names.

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