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

Annotations only declare non-read-only, open-world, non-idempotent, non-destructive, so the description carries real weight here and delivers: per-step pricing, the conditional gate on the $5 audit, single-payment semantics, refund of unexecuted steps, and the x402 USDC amount. It still omits what happens on payment failure or partial failure mid-ladder, and the shape of the returned verdicts.

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?

Two tight sentences that front-load the stage sequence and pricing, with the refund and x402 details trailing. Some phrasing is terse to the point of ambiguity ('Track record' of what), but nothing is wasted.

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?

Cost, gating, and refund behavior are covered well for a multi-stage payment tool, which is the critical risk surface. With no output schema, however, the description should say what each stage returns — particularly what an AVOID verdict looks like — since that determines whether the third step fires.

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?

There is a single parameter and schema coverage is 100%, so the schema already defines 'task' adequately. The description adds nothing about how one task string is distributed across the three stages or whether it needs to be phrased for pre-hire screening — baseline 3 applies.

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 names the concrete stages (track record, pre-hire background check, MASSAT audit) and the conditional gate between them, so an agent knows this is a tiered composite pipeline. It stops short of explicitly differentiating itself from siblings like bundle.prehire-ladder or security.massat-audit, which recombine near-identical steps.

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?

There is no statement of when to choose this bundle over the standalone agent.prehire-check, security.massat-audit, or the sibling bundle.prehire-ladder / bundle.enterprise-ladder. The conditional ('audit runs only if the verdict is not AVOID') describes execution behavior, not selection criteria, so the agent must infer fit from pricing and step names alone.

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