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

With no annotations, the description carries the full behavioral burden. 'From YOUR wallet' implies the operation is signed and gas-paid by the caller's own key, but nothing states that this is an irreversible on-chain write, what permissions/API key are required, or what happens on failure. The key behavioral facts are left to inference.

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, front-loaded sentence with no filler, which is good. But the terseness tips into cryptic phrasing ('YOUR wallet') rather than earning its place with useful detail.

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?

This is a 5-parameter on-chain write with no annotations, no output schema, and 40% parameter coverage. For that complexity the description is far too thin: it omits prerequisites, side effects, and the meaning of three required hash/environment arguments.

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%: apiKey and payerPrivateKey are documented in the schema, but identityHashHex, executionHashHex, and environmentUuidHex have no descriptions anywhere. The description mentions no parameter names or formats, so it fails to compensate for the coverage gap on three required fields.

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 gives a concrete verb and resource: it links a PQ identity hash to an execution hash on the Veya.sol contract. That is specific enough to know what the tool does. However, it offers no differentiation from close siblings such as veya_anchor_proof or veya_attest_execution, which an agent could easily confuse it with.

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 guidance on when to use this versus veya_anchor_proof, veya_attest_execution, or veya_register_pq_onchain, and no stated prerequisites. The phrase 'from YOUR wallet' hints at a wallet-signed path but does not define the condition that selects this tool.

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