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

Annotations already flag destructiveHint=true and readOnlyHint=false, and the description discloses the consequential behavior: it creates and funds an on-chain escrow in USDC before executing the task. This makes the money-moving, irreversible nature of the operation explicit, which goes well beyond a generic 'executes a task.' It does not discuss idempotency or refund behavior, but the existing hints plus the workflow description cover the main risk.

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, each earning its place: the first states the core action, the second lists the multi-step execution mechanics, and the third names the intended audience. The core action is front-loaded, and there is no filler or tautology.

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?

With a full input schema, an output schema, and annotations marking destructive behavior, the description completes the essential picture for an agent deciding whether to invoke it. The key contextual risk—on-chain USDC escrow funding—is explicitly stated. Minor gaps like failure modes and refund behavior are less critical here because the tool has an output schema and the description clearly frames the workflow.

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 coverage is 100%, so capability, task_input, and max_price_usdc are fully documented with descriptions, examples, and defaults. The description adds only loose mapping between workflow steps and parameters ('Searches by capability,' 'The task to send'), which is marginal value. Baseline 3 applies because the schema carries the burden.

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 ('Hire... to execute a task'), names the resource (marketplace agents), and outlines the full pipeline: search by capability, create escrow, fund on-chain, execute, and return the result. It clearly distinguishes itself from sibling discovery/registration tools by calling itself the 'one-call bridge,' even though it does not name a specific sibling.

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 phrase 'one-call bridge for local orchestrators (Claude Code, Cursor, etc.)' gives clear context for when this tool is appropriate: when the caller wants a single call that goes from capability to executed result. It implies the multi-step alternative without naming specific alternatives or exclusions, so the when-not-to-use guidance is slightly implicit rather than fully explicit.

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