# Pre-Human Agent Command Threat Screening Procedure

> Pre-Human Agent Command Threat Screening Procedure is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Scores and classifies a proposed agent command for risk before it reaches a human approver, routing low-risk commands to auto-allow and high-risk ones to a human review queue with evidence summaries.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pre-human-agent-command-threat-screening-procedure-3ccffd6a
```

Example prompt: Before I let this agent command go through, screen it for risk — classify whether it's read-only, fund-moving, data-exfiltration, or irreversible, score its blast radius and novelty, and tell me if it should be auto-approved or escalated to a human with an evidence summary.

## When to prefer this

Choose this endpoint when you need automated pre-screening of agent commands before they reach a human approver — especially in high-volume agentic workflows where human fatigue leads to missed threats. Prefer this over generic risk APIs when you need command-class-specific scoring (read-only vs fund-moving vs irreversible), blast radius estimation, and queue management logic tuned for agentic oversight contexts.

## Known failure modes

- Missing or malformed `input` object returns a schema validation error
- Unsupported HTTP method (e.g. POST) rejected by enum constraint
- Unpaid request without x402 payment returns 402 Payment Required
- LLM generation failure may return a degraded or empty `brief` field
- Topic override not recognized may fall back to default classification logic

## How this service works

Decision procedure that scores a proposed agent command for risk before it reaches a human approver: classifies commands (read-only, fund-moving, data-exfiltration, irreversible), scores each by blast radius and novelty, routes low-risk to auto-allow and high-risk to a human with a three-bullet evidence summary, caps the human approval queue to prevent fatigue, and recalibrates thresholds from weekly missed-threat audit. Addresses the quantified failure where humans miss one in three threats

## Output

Returns a decision procedure brief (`brief`) with a risk classification (read-only, fund-moving, data-exfiltration, or irreversible), blast radius and novelty scores, a routing decision (auto-allow or escalate to human), and a three-bullet evidence summary for human reviewers. Also includes service metadata, generation source, and an ISO-8601 timestamp.
