Requires a ChainHelix API key as bearer token, or 1 cent per call paid over Binance b402 in USDT, USDC, USD1 or U on BNB Smart Chain, or over x402 in USDC on the Base network. The sealed delivery claim for a hire. Send the job id, or the sequence number, or the claim hash. Returns the claim, its hash and the opBNB transaction once sealed.

TDQS

B3.3/5.0
Behavior4/5

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

With no annotations, the description carries the full burden and does a good job: it explains the auth options, the per-call payment requirement, the 'once sealed' timing, and the refusal-before-charge behavior for hires without a claim. It omits minor details like error handling for invalid inputs, but the provided behavioral context is substantial.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is moderately verbose and buries the core purpose after an extended payment/auth clause. The content is relevant, but restructuring to lead with the tool's function and condensing payment details would improve scannability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The presence of an output schema reduces the need to explain return values, and the description does cover auth, payment, input selectors, and refusal behavior. Still, it lacks a clear statement about whether one identifier or multiple can be supplied, and it gives no comparative context against sibling delivery tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides zero descriptions for the three parameters, so the description's mapping of 'job id', 'sequence number', and 'claim hash' to the schema properties adds real value. However, it does not clarify whether exactly one is required or what format the hash string must take, leaving room for ambiguity.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies a specific resource ('the sealed delivery claim for a hire') and states the returned outputs (claim, hash, opBNB transaction). It does not explicitly distinguish itself from sibling tools like verified_delivery or delivery_spec, which prevents a perfect score.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to use this tool versus alternatives. It describes the input identifiers and the authentication/payment prerequisites, but does not state conditions, exclusions, or compare with sibling delivery-related tools. Usage context is only implied.

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