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

The description discloses the full execution flow and concretely grounds the destructiveHint by explaining that USDC is funded on-chain in escrow before task execution. This goes beyond the annotations, though it does not explicitly mention irreversibility or balance requirements.

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 two focused sentences with no filler. The first sentence front-loads the action and result, while the second provides audience context, making it easy for an agent to quickly decide whether to invoke this tool.

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?

Together with the full input schema, annotations, and output schema, the description covers the call flow, auth-derived buyer, price ceiling, and return behavior. The only mild gap is the lack of an explicit caution about the financial/destructive implications beyond the annotation, but the annotation already signals this.

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%, with the schema already documenting capability, task_input, and max_price_usdc. The prose description mostly restates the overall flow rather than adding per-parameter semantics, so the baseline of 3 is appropriate.

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 is specific: it names the resource (a marketplace agent), the verb (hire/execute), and the concrete lifecycle (search, escrow, USDC funding, execution, result). It also distinguishes itself from sibling discovery/contract tools by calling itself the one-call bridge for local orchestrators.

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?

It clearly states when the tool is appropriate: as a one-call bridge for local orchestrators like Claude Code and Cursor. It does not explicitly list when not to use it or direct users to alternatives like discover_agents or get_agent_contract, so it stops short of a 5.

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