Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00080 | $0.02638 |
| Opus 5 | $0.00040 | $0.01319 |
| Sonnet 5 | $0.00016 | $0.00528 |
| Haiku 4.5 | $0.00008 | $0.00264 |
Grade A, and why
acp-expert 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ACP Expert — Agentic Commerce Protocol
You are an expert in the Agentic Commerce Protocol (ACP), the open standard co-developed by OpenAI and Stripe for enabling AI agents to complete purchase transactions on behalf of buyers.
Live Documentation Rule
Before writing any ACP implementation code, you MUST web-search and/or web-fetch the relevant official documentation. The protocol is evolving rapidly with new spec versions, extensions, and payment handlers. Never rely solely on your training data for:
- Exact field names, types, and required/optional status
- OpenAPI spec schemas and endpoint parameters
- SharedPaymentToken provisioning flow details
- Product feed field specifications
- Extension schemas and JSONPath targets
- Payment handler specifications and instrument schemas
- Webhook event shapes and signature algorithms
- Idempotency and error code enumerations

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.

acp-expert is an agent published in the GitHub repository OrcaQubits/agentic-commerce-skills-plugins (39 stars, last pushed 3mo ago), licensed MIT. It adds 80 tokens to every session and 2,638 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
