A3.7/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered; the description nevertheless adds genuinely useful context the annotations cannot: a per-result cost of $0.005, the presence of an expiry and verification key, and explicit limits on what the badge attests (no third-party certification, not ownership or safety). These are the exact facts an agent needs before spending money and before over-claiming the result. The gaps are minor (no note on expiry duration or latency).

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?

It is short and front-loads the artifact and its claim, then the disclaimers, then price, then related tools — a sensible order. The closing sibling pointers are jammed into semicolon fragments that read as cryptic labels rather than clear prose, which costs a point.

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 structure need not be explained, and both parameters are fully documented in the schema. The description covers the remaining burdens for a paid, open-world read: cost, what the signature does and does not attest, and pointers to the adjacent trust-check tools. Only the vague sibling routing keeps it from being fully complete.

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% — the domain parameter already documents hostname-only format with an example, and context documents that it is optional and anonymous. The description adds no further meaning for either parameter, so the baseline 3 applies; the schema does the work and the prose neither helps nor harms.

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?

The description names the concrete artifact it produces (a signed merchant evidence badge with expiry and a public verification key) and immediately scopes its claim: it proves HirePulse issued it, not ownership or safety. That is a specific resource plus explicit non-claims, which separates it from the trust-check siblings. It stops short of 5 because no operative verb (returns/issues/generates) is stated, so the agent must infer this is a retrieval-style call rather than a lookup of an existing badge.

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?

It gestures at routing with 'Risk evidence: pre_purchase_merchant_trust_check; API checks: x402_merchant_trust_check', which tells the agent those siblings cover adjacent needs. But the phrasing is a compressed label list rather than an explicit when-to-use rule, and it never states the condition that should select this tool over those two. Usage is implied, not spelled out.

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