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

With no annotations, the description carries the full disclosure burden. It valuably discloses the non-obvious protocol trait that this tool only issues a voucher and the caller must submit the accept transaction separately. It omits auth requirements, voucher expiry/reuse semantics, and error/return behavior.

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?

Two short sentences with no filler, and the core action is front-loaded before the follow-up responsibility. Slightly cryptic parenthetical phrasing, but no wasted words.

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?

No output schema, no annotations, and 0% parameter coverage means the description should do more. It adequately conveys the unusual two-step hand-off, which is the most important thing, but leaves return format, auth needs, and parameter meaning under-specified.

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 both parameters. It clarifies that 'token' is the wallet token, which is genuinely helpful, but says nothing about what 'job' means (job identifier vs index) or its accepted range/format.

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?

States a specific action (request a voucher) against a specific resource (a job), and clarifies the two-step nature of the flow. It does not name or contrast sibling tools like job_complete or jobs, so an agent must infer ordering from the description alone.

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?

'You then send the accept transaction yourself' implies this is a prerequisite step before accepting a job on chain, which is usable context. However, there is no explicit when-to-use, no stated prerequisites (wallet auth), and no mention of the alternative job_complete or jobs tools.

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