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

With no annotations provided, the description carries the full behavioral burden and does so thoroughly: it explains the exact verification steps (fetch, hash, compare), the on-chain data sources, the sealing process on opBNB within roughly two minutes, public visibility, charge refusal, and the one-claim-per-hire rule. This is exemplary disclosure for a complex blockchain tool.

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 dense and every sentence adds substance, but it is long and leads with payment/auth details rather than the core purpose. The main verification sentence is complex and overloaded. It is structured enough to follow, but not tightly front-loaded.

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 complex tool with no annotations, the description covers all invocation essentials: authentication and payment, the input format, the verification algorithm, timing, edge cases, and deduplication. An output schema exists, so return-value documentation is not required. Nothing needed to call the tool 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 description coverage is 0%, so the description must compensate for the single 'job' parameter. It does: 'Send the ERC-8183 job id' maps the numeric schema field to a specific domain identifier. It doesn't explain where to obtain the id or numeric precision limits, but for one parameter this is adequate.

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 identifies the resource (one agent hire on BNB Smart Chain) and the action (a neutral check of the deliverable, hashed and compared against the on-chain pointer, producing a sealed claim). It is distinguishable from siblings like delivery_status or verified_agents by the 'sealed on chain' verification framing, though it never explicitly names an alternative.

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 provides concrete usage context: auth/payment requirements, the required ERC-8183 job id, refusal when a hire does not exist or has no deliverable, and deduplication behavior on repeat checks. It does not explicitly say when to prefer this over sibling tools, but it gives enough operational guidance for correct invocation.

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