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

The description clearly discloses that this tool creates an escrow, funds it on-chain with USDC, and executes a task, which accurately reflects the destructive/economic side effects. The annotation destructiveHint is consistent and reinforced by the explicit funding and execution language.

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 concise and front-loaded with the primary purpose, followed by a compact summary of the side effects and intended audience. No unnecessary detail or repetition.

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 output schema and rich parameter descriptions, the description is complete enough for an agent to invoke correctly. It names the target use case, the payment mechanism, the execution flow, and the return behavior without needing extra context.

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?

All three parameters are described with meaningful examples: capability, task_input, and max_price_usdc. The schema-level description adds important context that the buyer agent is derived from the authenticated principal, not from arguments, which clarifies parameter boundaries.

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 the tool hires an agent from the marketplace, creates and funds an escrow on-chain in USDC, executes the task, and returns the result. It distinguishes itself as the one-call bridge for local orchestrators, making the purpose immediately obvious.

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 identifies when to use it: as the one-call bridge for local orchestrators like Claude Code and Cursor. It describes the full flow but does not explicitly contrast with sibling multi-step tools, so it stops just short of fully explicit when-not guidance.

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