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

With no annotations, the description carries the full burden and does so thoroughly: it discloses exactly what is fetched and hashed, what is compared against the on-chain pointer and index, which data comes from chain, that the claim is hashed and sealed on opBNB from a dedicated key within ~2 minutes, that it stays public, that invalid hires are refused before charge, idempotency behavior, and the 5-cent price. That is a rich, unusually complete behavioral profile.

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 purpose is front-loaded in the first clause, and the dense run-on sentences each carry distinct information (inputs, checks, sealing, refusal, idempotency, price). It is information-dense rather than padded, but the heavy semicolon chaining makes it harder to scan than it could be.

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?

An output schema exists, so return values need not be explained, and the description still covers behavior, refusal conditions, idempotency, and pricing for a single-parameter tool. Nothing an agent needs to invoke it correctly appears to be missing.

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 0% for the single 'job' parameter (typed only as number), so the description must compensate. It does by identifying the value as the 'ERC-8183 job id' and describing what that job resolves to, adding real semantic meaning beyond the bare schema, though it gives no format constraints.

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 opening states a specific verb and resource: 'A neutral check of one agent hire on BNB Smart Chain, sealed on chain,' then clarifies the input is an ERC-8183 job id. This is clearly a delivery-verification tool, distinguishable from adjacent siblings by its focus on hire deliverables and on-chain sealing, though it never names an alternative explicitly.

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?

It implies when to call it ('Send the ERC-8183 job id') and gives useful edge conditions ('A hire that does not exist or has no deliverable yet is refused before any charge'; 'a repeat check returns the claim on record'). However, it never contrasts itself with siblings such as delivery_status or verify_fill, so the agent must infer the choice of tool.

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