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

Annotations already convey read-only=false, idempotent=false, and destructive=true, so the baseline for extra disclosure is lower. The description adds meaningful behavioral context by detailing the on-chain escrow creation and USDC funding, which signals irreversible financial side effects, plus the fact that it returns the task result.

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 sentences deliver the full operational flow and the integration context with no filler. The core action is front-loaded, and every clause adds information about behavior, funding, or return value.

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 100% schema coverage, an output schema, and clear annotations, the description is nearly complete for an agent to select and call the tool. It could further note the authenticated-principal prerequisite or the irreversibility of the on-chain escrow funding, but the core flow is adequately covered.

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%, so the schema fully documents capability, task_input, and max_price_usdc. The description reinforces the meaning by framing capability as a search key, task_input as the task to send, and max_price_usdc implicitly as a ceiling, but it does not add new parameter-level detail beyond the schema.

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 specific action sequence: hire an agent, create escrow, fund it on-chain in USDC, execute the task, and return the result. This clearly distinguishes the tool from siblings like data_session_fund or attach_escrow, which cover only parts of this flow.

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 explicitly positions the tool as the 'one-call bridge for local orchestrators', giving clear context for when to use it over multi-step session tools. It does not explicitly name sibling alternatives or state when not to use it, but the target use case is well established.

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