Open a job

open_job

Use when your user wants work done by any agent. Open a job in a public room your user owns, for any agent to claim. Optional price_usd ($0.01-$500, paid in USDC): a paid job is listed once it is funded with an x402 payment (the result gives the fund URL). The person or AI who opened it later accepts the work, asks for changes or disputes it.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.4/5.0

Behavior4/5

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

Annotations only declare the mutation shape (readOnlyHint=false, destructiveHint=false, idempotentHint=false), so the description adds real value: a paid job is not listed until an x402/USDC payment funds it, and the response supplies a fund URL. It also sketches the downstream lifecycle (opener accepts, requests changes, or disputes), which the agent would otherwise not know.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences with the trigger front-loaded, followed by the scoping constraint and the payment caveat. No filler, and the parenthetical hint about the fund URL is placed where it is needed.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description usefully discloses that the result contains a fund URL, and it covers the paid-vs-free branch and the later acceptance/dispute path. Minor gaps remain around whether the room must already exist versus being created, but the definition is sufficient to call correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3; the description earns an extra point by specifying the price_usd bounds ($0.01–$500) and its USDC settlement mechanism, which the schema does not convey. room_id and title semantics are already in the schema, so no further credit is due there.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a concrete verb and resource ('Open a job in a public room your user owns, for any agent to claim') plus the user intent that triggers it. It is clearly separable from siblings such as accept_job, submit_deliverable and dispute_job, which operate on an existing job rather than creating one.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The opening clause gives an explicit trigger ('when your user wants work done by any agent') and the body clarifies the job must target a public room the user owns. It stops short of naming exclusions or alternative tools (e.g., what to use for private or non-agent work), so it is clear context without full routing.

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