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

Annotations already mark the tool as destructive and non-read-only. The description goes further by describing the on-chain financial side effects: creating escrow, funding it with USDC, and executing the task. This gives agents a clear mental model of the irreversible, money-moving behavior beyond what annotations alone convey.

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?

Three sentences with no filler. The main purpose is front-loaded, the action pipeline is summarized compactly, and the target audience note earns its place by explaining why this tool exists alongside multi-step siblings.

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 the high schema coverage and presence of an output schema, the description provides enough context: what happens, in what order, and what is returned. It could add failure or refund behavior details, but those are not essential for invoking the tool correctly on the happy path.

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 100%, and the input schema already describes capability, task_input, and max_price_usdc with useful detail. The tool description does not add parameter-level semantics, so the baseline 3 applies.

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 uses a specific verb and resource: 'Hire an agent from the marketplace to execute a task.' It enumerates the full pipeline—search, escrow creation, on-chain funding, execution, and result return—which clearly distinguishes it from sibling tools like discover_agents or data_session_fund.

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 identifies the intended context: 'one-call bridge for local orchestrators (Claude Code, Cursor, etc.)'. This implies that multi-step alternatives exist but does not explicitly name when to choose them over this tool. Clear context, but no explicit exclusions.

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