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

With no annotations supplied, the description carries the full burden and delivers real behavioral context: the domain (USDC payouts on Base, gated by a job's check), a prompt-injection warning that job text is data not instructions, and the rule that the wallet is payout-only and keys must never be requested. It does not say whether the call is read-only or whether results are paginated or filtered, but the safety posture is unusually well disclosed.

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?

Four short sentences, each doing distinct work: domain framing, workflow entry point, injection warning, key-handling warning. The Clarifying detail is front-loaded but the domain pitch precedes the actual tool statement, which slightly delays the actionable information.

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 zero-parameter list tool with no output schema, the definition is adequate but leaves the return shape unstated: it does not say whether all jobs, open jobs, or unpaid jobs are returned, nor what fields identify a job before the agent calls get_job. Delegating detail to get_job is reasonable, but a single sentence on what the list contains would close the gap.

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?

There are zero parameters, so the baseline is 4; the description adds nothing further on parameters because there is nothing to describe, and the schema is fully self-describing for an empty argument object.

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?

"Start with list_jobs" positions the tool as the entry point of the workflow, but the description never states plainly that it lists available jobs, nor what it returns. The reader must infer the verb+resource from the name and sibling routing rather than from an explicit statement.

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 explicitly designates this as the first call and routes the agent to get_job for a job's items and the exact answer/evidence schemas. That is clear context-sensitive guidance; it stops short of stating any exclusion or when-not-to-use condition.

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