stripe-security-audit

stripe-security-audit is a skill for Claude Code, Codex from appeeky/stripe-skills. It costs 61 tokens per session (321 once invoked), scanned A, original, MIT.

A check of how a Stripe integration protects payment keys, webhooks, customer card data, and payment-processing responsibilities. A webhook is a message Stripe sends to your application when something happens, such as a payment failure.

In plain words
What is it for?
Use it to scan code for leaked keys, review restricted-key use, check webhook signature verification, assess PCI responsibilities, and identify keys that should be rotated.
Why use it?
It helps find exposed secrets, unsafe logging, unverified webhook messages, weak access controls, and unnecessary handling of card details.

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

stripe-security-audit 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 2mo 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.

What it actually says

Stripe Security Audit

Combines codebase scan + account settings review.

Codebase scan

Grep for leaked secrets: sk_live, sk_test, rk_live, whsec_, hardcoded keys outside env.

Checklist

Area Check
Secret keys Only in env/secrets vault, never client or repo
Publishable key pk_ only on client (safe)
Restricted keys Used for scoped/agent access, least privilege
Webhook whsec_ verified, not skipped
PCI scope Using Checkout/Elements (SAQ-A), not raw card handling
Logging No full card / secret / client_secret in logs
Key rotation Old keys revoked in Dashboard

Output Template

Security Audit

Critical:
- [leaked/hardcoded key at file:line]
Harden:
- [use restricted key for X]
OK:
- [Checkout keeps PCI scope minimal]

Immediate: [rotate/remove any exposed key]

If a live secret key is found in the repo, advise rotating it immediately in the Dashboard.

Changes

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.
