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

Annotations are absent, so the description carries the full disclosure burden. It implies an on-chain write from the user's wallet but says nothing about gas payment, irreversibility, required credentials, or what happens on failure; the only write-permission hint lives in the schema, not the description.

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?

It is a single tight sentence with no filler, so nothing is wasted. But the brevity reflects under-specification rather than disciplined conciseness, leaving essential scope and mechanics unstated.

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 five-parameter on-chain write tool with no annotations, no output schema, and only 40% schema coverage, the description is materially incomplete. An agent lacks the prerequisites, alternatives, and parameter semantics needed to invoke it confidently.

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 only 40%, so the description should compensate but does not. The phrase 'ML-DSA bytes' loosely maps to mldsaSigHex, but environmentUuidHex, blake3HashHex, apiKey, and payerPrivateKey receive no explanation of their role in this specific call.

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?

Names a specific function (attestExecution) on a specific contract (Veya.sol) and indicates the wallet and signature inputs, which is more than a tautology. However, it never explains what 'attesting an execution' actually means and does not clearly distinguish itself from close siblings like veya_anchor_pq_attestation or veya_anchor_proof.

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?

No when-to-use, when-not-to-use, or alternative-tool guidance is present. With siblings such as veya_anchor_pq_attestation, veya_prove, and veya_sealed_execute available, the agent is left to guess when this tool is the correct choice.

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