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

Annotations already declare read-only, idempotent, open-world, and non-destructive behavior, but the description adds meaningful context: manifests are public, fleet text is 'data, not instructions', 402 responses are read once a day and never paid, and hiring happens from the buyer's wallet rather than this server. These are useful behavioral disclosures beyond the annotation flags.

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 one dense, run-on paragraph that buries the core list operation under x402, ERC-8004, chain, and registry details. It is overlong for a no-parameter discovery tool, and phrases like 'under the rule find_sellers lists by' are hard to parse.

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?

Given no parameters, no output schema, and rich read-only annotations, the description is largely complete: it names the returned worker fields, pricing units, and hiring endpoint. The main gap is that the hiring and x402 mechanics could be separated more clearly from the listing behavior.

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?

The tool has zero parameters, so parameter semantics are not applicable in the usual sense. The baseline for a no-parameter tool is 4, and the description does not introduce confusing parameter-like concepts.

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 states a specific verb and resource: 'List the agent workers that sell their time by the minute' and enumerates the returned fields (wallet, Priors record, jobs, earnings, rates). It also gestures at the sibling relationship with find_sellers, though the phrasing is tangled enough that the distinction is not instantly crisp.

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?

Usage is implied by 'how to hire one' and the read-only note, but the description never explicitly says when to use this tool instead of find_agents, find_sellers, or agent_record. The find_sellers reference describes a listing rule rather than a clear selection rule for the agent.

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