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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00075 | $0.01208 |
| Opus 5 | $0.00037 | $0.00604 |
| Sonnet 5 | $0.00015 | $0.00242 |
| Haiku 4.5 | $0.00007 | $0.00121 |
Grade A, and why
stripe 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 11d 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stripe Billing Operations
Execute billing and payment operations on Stripe: customers, products, invoices, payment links, subscriptions, refunds, and disputes.
MCP is optional. This skill works with MCP (auto), Stripe CLI, or Dashboard. See BACKENDS.md for execution options.
Three Hard Rules
- Read before write — Before creating customer/product/price, check if it already exists to avoid duplicates
- Money operations require confirmation — Refunds, subscription changes, dispute updates must be confirmed before execution
- When in doubt, search — If unsure about object ID or parameters, search first, don't guess
Security Rules
| Operation Type | Rule |
|---|---|
| Read (list, get, search) | Execute directly |
| Create (customer, product, price, invoice) | Check for duplicates first |
| Money (refund, subscription cancel/update, dispute) | Display details → Await confirmation → Execute |
| Mode | Test mode by default. Live requires explicit "live mode" + double confirmation |
Dangerous Actions (Require Confirmation)
Before executing these operations:
- Display — Show object ID and key fields
- Explain impact — Amount, timing, consequences
- Await confirmation — Wait for explicit "confirm"/"yes"/"proceed"
- Execute and receipt — Return result + object ID + status
| Action | Risk |
|---|---|
create_refund |
Money leaves account |
cancel_subscription |
Revenue loss |
update_subscription |
Contract change |
update_dispute |
Legal implications |
Example confirmation prompt:
About to execute refund:
- PaymentIntent: pi_xxx
- Amount: $50.00 (full amount)
- Reason: requested_by_customer
Reply "confirm" to proceed, or "cancel" to abort.
Common Workflows
Create Customer
1. Search/list to check if customer exists (by email)
2. If not exists, create_customer(name, email, metadata)
3. Return cus_xxx + key info
Create Product and Price
1. List products to check if already exists
2. create_product(name, description)
3. create_price(product=prod_xxx, unit_amount=cents, currency)
4. Return prod_xxx + price_xxx
What ships with it
3 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.

stripe is a skill published in the GitHub repository Heyvhuang/ship-faster (339 stars, last pushed 26d ago), licensed MIT. It adds 75 tokens to every session and 1,208 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.
