Implement Stripe integrations for SaaS billing: subscriptions, checkout, proration, usage- based billing, idempotent webhooks, customer portal, dunning, and SCA.

  • Building billing
  • SKILL.md covers Core Capabilities, When to Use, Clarify First and References, plus 3 more sections
  • Runs Python scripts from its folder; calls stripe
  • Handling webhooks

What it does

Stripe Integration Expert is an agent skill from borghei/Claude-Skills. Implement Stripe integrations for SaaS billing: subscriptions, checkout, proration, usage- based billing, idempotent webhooks, customer portal, dunning, and SCA. Use when building billing, handling webhooks, or testing with Stripe CLI.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts and reference files (for example `references/payment-flows.md`, `references/subscriptions.md` and `references/testing-and-troubleshooting.md`).

It sits in Backend & APIs, covering Webhooks and Payments and billing. It works with Stripe, Django and Next.js. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.

When your agent uses it

  • Building billing
  • Handling webhooks
  • Testing with Stripe CLI

Example prompts

  • “/stripe-integration-expert”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 4a698e8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • stripe

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Stripe Integration Expert loads about 1.6k tokens when it runs, and up to ~7.7k if it reads all its reference files. Until then it costs about 65 tokens; SKILL.md has 645 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Stripe Integration Expert

The agent builds production-grade Stripe integrations for SaaS billing: subscription lifecycle management with trials and proration, idempotent webhook handlers, usage-based metered billing, Checkout sessions, Customer Portal, dunning recovery, and SCA/3D Secure compliance. Provides patterns for Next.js, Express, and Django with emphasis on real-world edge cases.

Core Capabilities

  • Checkout & client setup — pinned-version Stripe client, centralized plan config, Checkout sessions with trials, tax collection, and promo codes
  • Subscription lifecycle — a state machine covering trialing → active → past_due → canceled, plus upgrades/downgrades with proration previews and reactivation
  • Idempotent webhooks — signature verification, event dedup, re-fetch-from-API handlers, and retry-safe processing
  • Usage-based billing & gating — metered usage records, feature gating by plan, and grace-period access logic
  • Dunning & SCA — payment-failure email sequences and PSD2 / 3D Secure authentication flows
  • Local testing — Stripe CLI webhook forwarding, event triggers, and test card matrix

When to Use

  • Building SaaS subscription billing from scratch on Next.js, Express, or Django
  • Adding plan upgrades/downgrades with correct proration behavior
  • Hardening or debugging a webhook endpoint for idempotency and retry safety
  • Implementing metered/usage-based billing or feature gating by plan
  • Adding dunning recovery or European SCA/3D Secure compliance

Clarify First

Before building the integration, confirm these inputs. If any is unknown or vague, ASK — do not assume:

  • Framework — Next.js / Express / Django (the handler and client patterns differ per stack)
  • Billing model — flat subscription / metered usage-based / trials + proration (shapes the subscription state machine and code)
  • Scope — which piece: Checkout, idempotent webhooks, dunning, or SCA/3D Secure (selects the reference and code generated)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

References

Load the reference that matches the task — keep this file lean and pull detail on demand:

  • references/payment-flows.md — Stripe client setup, plan config, Checkout sessions, Customer Portal, and SCA/3D Secure. Read when wiring up the client or building the checkout/portal redirects.
  • references/subscriptions.md — lifecycle state-machine diagram, upgrade/downgrade/preview/cancel code, usage-based billing, feature gating, and the Prisma schema. Read when modeling subscription state or implementing plan changes.
  • references/webhooks.md — the full idempotent webhook handler with signature verification and every event handler. Read when building or auditing the webhook endpoint.
  • references/testing-and-troubleshooting.md — Stripe CLI testing, common pitfalls, troubleshooting table, and success criteria. Read when testing locally or diagnosing a billing bug.

Scope & Limitations

This skill covers:

  • Stripe Checkout, Subscriptions, and Customer Portal integration for SaaS billing
  • Webhook handling with idempotency, signature verification, and retry safety
  • Usage-based (metered) billing, proration previews, and plan change workflows
  • SCA/3D Secure compliance for European payment regulations (PSD2)

This skill does NOT cover:

  • Stripe Connect (marketplace payouts, multi-party payments) -- see platform-specific Stripe Connect documentation
  • One-time payment flows without subscriptions (e.g., e-commerce product purchases)
  • Tax calculation and remittance (Stripe Tax configuration, VAT/GST filing) -- see ra-qm-team/ compliance skills for regulatory guidance
  • Payment fraud detection and dispute management (Stripe Radar rules, chargeback workflows) -- see skill-security-auditor for security review patterns
