hire_quote

Requires a ChainHelix API key as bearer token, or 2 cents per call paid over Binance b402 in USDT, USDC, USD1 or U on BNB Smart Chain, or over x402 in USDC on the Base network. Ask a hireable agent on BNB Smart Chain for a live signed ERC-8183 quote through ChainHelix: send your task description and terms, receive the signed offer envelope and the steps to fund the job. Only agents the live map lists as hireable

TDQS

A4.1/5.0
Behavior5/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It transparently explains authentication/payment paths, the type of result returned (signed offer envelope and funding steps), and the eligibility constraint. It makes clear the tool requests a quote, not immediate funding, which is valuable behavioral context.

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

Conciseness4/5

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

The description is three dense sentences with no filler; each sentence carries distinct information about requirements, outcome, and eligibility. The payment routing details are long but relevant to successful invocation. It is slightly back-loaded because requirements precede the core action, but the structure remains clear.

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

Completeness3/5

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

The description gives strong selection-level context and an output schema exists for the return envelope, so the outcome is reasonably covered. However, the unexplained required id and vague terms parameter leave an agent without enough detail to construct a valid request confidently. With no annotations and no schema property descriptions, this gap is significant.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate for explaining the three parameters, but it only loosely mentions 'task description and terms'. The required numeric id is never explained, including where it comes from or how it relates to the live map of hireable agents. The terms object format is also left unspecified.

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?

The description clearly states a specific action: ask a hireable agent on BNB Smart Chain for a live signed ERC-8183 quote through ChainHelix. It identifies the resource and outcome, and it distinguishes itself from the hire_plan_* siblings by focusing on a live quote rather than a plan. The scope is concrete and actionable.

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 description gives clear context: call this when you need a live signed quote from a hireable agent before funding a job, and only use it for agents the live map lists as hireable. It also states important prerequisites such as the API key or per-call payment requirement. It does not explicitly name alternative tools or when-not conditions, so it falls 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.
