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

With no annotations at all, the description carries the full burden and does disclose some behavior: it requires a wallet token, is gated on the job's check passing, and returns a completion voucher. It says nothing about what happens when the check fails, whether calling is idempotent, or what the voucher is subsequently used for.

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?

A single short sentence with the action and its precondition front-loaded; there is no padding. The parenthetical wallet token note is compact rather than wasteful.

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 two-parameter tool with no output schema and no annotations, the essentials (precondition plus token) are present, but the description leaves the voucher concept, failure behavior, and follow-up steps unexplained, which an agent would need in a multi-tool job workflow.

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. It does clarify one parameter by tying 'wallet token' to the token field, and 'the job' implies the job identifier, but it adds no detail on format, range, or how the numeric job id is obtained.

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 names a concrete action (requesting the completion voucher) tied to the job_complete resource, but the framing 'ask for the completion voucher' does not cleanly map to 'complete a job' and does not distinguish this tool from siblings like job_ticket or jobs. An agent can infer the domain but not the precise effect.

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 supplies a real trigger condition — only call once the job's check passes — which is genuine when-to-use guidance. However, it never names an alternative tool or states when-not to use it (e.g., before the check passes, or versus job_ticket), leaving routing to inference.

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