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

No annotations are provided, so the description carries the full burden. It discloses the invocation contract ('POST JSON with code field') and the general nature of the output ('findings and suggestions'), which is more than nothing, but it omits auth/payment requirements (implied by the x402 prefix), determinism, and any limits.

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 sentences, front-loaded, with no filler. The only minor waste is the redundant 'bankr-code-review:' prefix, which restates the tool name rather than adding information.

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?

The tool is simple and the description covers the input contract, which matters given the empty schema. However, with no output schema, the return value ('findings and suggestions') is left vague, and the stated 'code field' is not reflected in the schema, creating a mismatch an agent must reconcile.

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 schema declares zero properties, so the description is the only source of input semantics and it supplies the essential 'code' field. That makes it genuinely additive, though it stops short of noting optional parameters or format constraints for that field.

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 verb and resource ('Automated code review for diffs and snippets'), making the function immediately identifiable. It does not, however, distinguish itself from close siblings like x402-ai-code-review or x402-ai-diff-review, so an agent cannot tell which to prefer without further inference.

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 phrase 'for diffs and snippets' implies the applicable input scope, giving some usage context. But there are no explicit when-to-use/when-not conditions and no mention of the near-identical alternatives in the sibling list, leaving routing to guesswork.

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