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

With no annotations provided, the description carries the full burden. It explains the cryptographic checks and the purpose of binding allocations to prevent manipulation. However, it does not disclose failure behaviors, side effects (though likely read-only), or return details.

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 concise with three sentences. It front-loads the main action, then details checks, then provides context. No unnecessary words.

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?

Given a simple one-parameter tool with no output schema, the description covers verification purpose and checks. However, it omits return value information and error handling. Sibling tools suggest a verification suite, but this tool's boundaries are not fully specified.

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 100% for the single 'token' parameter, and the description adds no additional semantics beyond the schema's type and description. The tool's main description provides context for the token's role, but no parameter-specific guidance.

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 clearly states the action ('Verify a reward commitment token's cryptographic integrity') and specifies the resource. It details what checks are performed (Merkle tree, signature, amounts) and distinguishes this from sibling verification tools like verify-issued-gmv and verify-receipt.

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 does not provide explicit guidance on when to use this tool versus other verification tools, nor does it mention prerequisites or conditions. Usage context is only implied through the tool's function.

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