payment-failure-audit

payment-failure-audit is a skill for Claude Code, Codex from appeeky/stripe-skills. It costs 55 tokens per session (493 once invoked), scanned A, original, MIT.

An audit guide for examining failed Stripe payments, including declined charges, failed payment attempts, invoice failures, and decline reasons. Stripe is a payment service, and a decline code describes why a payment was not accepted.

In plain words
What is it for?
Use it to review failed charges and PaymentIntents, find open subscription invoices, group failures by reason or card details, and assess payment failure rates.
Why use it?
It groups payment failures into patterns that can explain lost payments. This helps distinguish issues such as insufficient funds, expired cards, generic declines, and required authentication.

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

payment-failure-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

Payment Failure Audit

Stripe MCP Setup

Requires Stripe MCP connected via OAuth or restricted key. Docs: https://docs.stripe.com/mcp

  1. GetMcpTools with server: "user-Stripe" (or plugin-stripe-stripe) before any call
  2. Prefer stripe_api_search → stripe_api_details → stripe_api_read for list/retrieve
  3. Always paginate — limit: 100, follow has_more with starting_after
  4. Amounts are in cents unless noted
  5. Never expose secret keys in output

Workflow

  1. Recent failed charges — GetCharges with filter or search:
    • search_stripe_resources: charges:status:"failed" (paginate if possible)
  2. Failed PaymentIntents — GetPaymentIntents status requires_payment_method or failed
  3. Open invoices — GetInvoices with status: open and subscription set
  4. Group failures by:
    • outcome.reason / decline code
    • card.funding
    • card.country
    • Wallet vs direct card

Common Decline Reasons

Code / reason Typical fix
insufficient_funds Debit balance — dunning email
card_declined Generic — retry + update PM
expired_card Expiring card email
authentication_required Enable 3DS on setup
Radar block Review Radar rules

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.
