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

With no annotations, the description carries the full behavioral burden. It usefully discloses the cost and that the result is boolean, but it does not explain payment_token requirements, whether the operation is read-only, where the threshold comes from, or what happens on payment failure.

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?

The description is a single front-loaded sentence with no filler. It communicates the core purpose and cost efficiently.

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?

For a paid verification tool with no annotations, no output schema, and 0% parameter description coverage, the description is too sparse. It should clarify payment_token handling, threshold source, and expected failure modes, especially given the unexplained cost mechanism.

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%, so the description must compensate for undocumented parameters. It implies that wallet is the subject of the check and that a cost is involved, but payment_token is never explained, and the referenced threshold is not actually a parameter in the schema.

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 specific check: a boolean creditworthiness test for whether a wallet exceeds a score threshold. This is clearer than the sibling tools that retrieve full reports or public scores, though it does not explicitly name or contrast those alternatives.

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 boolean framing implies the tool should be used when only a pass/fail answer is needed, and the cost is disclosed. However, there is no explicit guidance on when to choose this over bureau_public_score, bureau_full_report, or other verification siblings.

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