ap2-risk-signals

ap2-risk-signals is a skill for Claude Code from OrcaQubits/agentic-commerce-skills-plugins. It costs 50 tokens per session (925 once invoked), scanned A, original, MIT.

A guide to AP2 risk signals: information used to assess fraud and trust in payments started by AI agents.

In plain words
What is it for?
Use it to construct risk payloads and support trust establishment, risk evaluation, fraud detection, and trust scoring for AP2 transactions.
Why use it?
It accounts for risks that ordinary payment systems may not cover, such as delegated purchases, absent users, and delays between authorization and payment.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ap2-risk-signals scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AP2 Risk Signals Framework

Before writing code

Fetch live docs:

  1. Fetch https://ap2-protocol.org/specification/ for risk payload specification
  2. Fetch https://ap2-protocol.org/topics/privacy-and-security/ for risk considerations
  3. Web-search ap2 protocol risk signals fraud agentic payments for risk framework details
  4. Web-search site:github.com google-agentic-commerce AP2 risk for implementation references

Conceptual Architecture

Why Risk Signals Matter

Agentic commerce introduces novel risk dimensions that traditional payment systems weren't designed for. AP2's risk signals framework provides a common language for all ecosystem participants to assess transaction risk.

Novel Agentic Risk Factors (from the official AP2 risk factor table)

Risk Factor Description
User asynchronicity User may not be present during the entire transaction journey
Delegated trust Agents initiate transactions on behalf of users
Mandate-merchant matching Verifying the purchase matches the authorized intent
Temporal gaps Time between token generation and payment execution
Indirect trust establishment CP and Merchant may not have a direct trust relationship
Agent identity verification Verifying the agent is who it claims to be

Additional AI-Specific Risks (not from the official AP2 risk factor table)

The following are additional AI-specific risk considerations relevant to agentic commerce implementations, but they are not part of the official AP2 specification's novel risk factor table:

Risk Factor Description
Agent hallucination AI agent may misinterpret user intent
Prompt injection Malicious inputs that manipulate agent behavior

Risk Payload

The risk payload is an open-ended field structure in V0.1:

  • Intentionally flexible for industry-specific risk signals
  • Allows Credentials Providers, Merchants, and Networks to pass custom risk data
  • Each actor contributes their own risk assessment signals
  • The payload travels with the mandate through the transaction flow

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
