TDQS

A3.8/5.0

Behavior4/5

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

readOnlyHint=true already tells the agent this is a non-mutating call, and the description reinforces that by framing the output as 'steps to fund the job' rather than funding it. It adds genuinely new behavioral data the annotations don't carry: a cost of 2 cents per call and the eligibility constraint that the agent must be listed as hireable. It does not say what happens when the id is not hireable or when terms are omitted.

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 sentences, front-loaded with what the tool returns, then the eligibility constraint, then the price. No sentence is redundant and the most decision-relevant facts (it's a quote, it's restricted to hireable agents, it costs money) come first.

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?

An output schema exists so return values needn't be described, and all three params are documented. The description supplies the safety/eligibility context and pricing an agent needs before calling. The one remaining gap is discoverability: it says agents must be hireable without pointing to the tool that yields a hireable id.

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

Parameters3/5

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

Schema coverage is 100%, so every parameter is already documented with types, examples and defaults (including the default terms object). The description only restates 'task description and terms' without adding format or constraint detail beyond the schema, so the baseline of 3 applies.

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

Purpose4/5

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

States a specific verb and resource: obtain a live signed ERC-8183 quote from a hireable agent on BNB Smart Chain, including the offer envelope and funding steps. The purpose is unmistakable, but it never names the obvious siblings (search_agents, verified_agents, hire_plan_*) so the agent must infer its niche from the surrounding tool list.

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

Usage Guidelines3/5

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

Usage is implied through the flow 'send your task description and terms, receive the signed offer envelope,' and it gives one precondition: 'Only agents the live map lists as hireable.' However it never says how to discover a hireable agent id (presumably search_agents/verified_agents) nor when to prefer hire_plan_gridtrader and friends over this generic quote.

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