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.

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 5.1 | $0.00123 | $0.05007 |
| Opus 5 | $0.00062 | $0.02504 |
| Sonnet 5 | $0.00025 | $0.01001 |
| Haiku 4.5 | $0.00012 | $0.00501 |
Grade A, and why
acp-client scanned grade A with 1 finding 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 6d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
Commerce Platform (ACP) API using composable `curl` recipes. Triggered by How it starts
The opening of the file, as written. The whole thing — 451 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ACP Client Skill
Execute checkout, cart, and order operations against the OpenLink Adaptive
Commerce Platform (ACP) API using composable curl recipes. Triggered by
natural-language purchase intents.
When to Use
- "I want to purchase
{product}" / "Buy{product}" / "Get me a license for{product}" - "Checkout
{product}" / "Create a checkout for{offer-id}" - "Update checkout
{id}" / "Change quantity for checkout{id}" - "Cancel checkout
{id}" / "Cancel my order" - "Complete checkout
{id}" / "Pay for checkout{id}" - "Add
{product}to cart" / "Create a cart for{product}" - "Get order
{order-id}" / "Check status of order{order-id}" - "Get a Stripe test token" / "Generate SPT for
{amount}" - "Use balance" / "Pay with balance"
- Any request referencing the ACP API, checkout sessions, carts, or OpenLink software license purchases.
- Accessing a paid/protected resource behind a 402 (MPP) paywall, when the authentication protocol (WebID-TLS/NetID-TLS, OAuth, Digest) or settlement route must be elicited. WebID-TLS/NetID-TLS always targets port 5443, never 443 — see the Auth Protocol Selection rule.

ACP Instances
Known ACP API endpoints. The default is shop.openlinksw.com; override via ACP_BASE_URL:
| Instance | URL |
|---|---|
| Shop (default) | https://shop.openlinksw.com/acp |
| QA / Staging | https://ods-qa.openlinksw.com/acp |
To use a non-default instance, set ACP_BASE_URL before invoking the skill:
export ACP_BASE_URL="https://ods-qa.openlinksw.com/acp"

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-client is a skill published in the GitHub repository OpenLinkSoftware/ai-agent-skills (38 stars, last pushed 2d ago), licensed MIT. It adds 123 tokens to every session and 5,007 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
