3. Ask your agent to inspect your project before coding.

4. Ask your agent to implement checkout, webhook verification, settlement, tests, and docs together.

How To Ask Your Agent

Use the skill name in your prompt:

Use $malaysia-payment-gateway to review my app payment flow and tell me what is missing before production.

Use $setup-curlec to implement Curlec checkout, callback verification, webhook settlement, and tests in this Next.js project.

Use $setup-chip to add CHIP Collect checkout and webhook handling. Do not unlock access from redirect alone.

Use $setup-xendit to implement hosted checkout with Xendit Payment Sessions and idempotent webhook settlement.

Use $setup-bayarcash to integrate Bayarcash payments with checksum/callback verification.

Use $setup-bcl to set up BCL Pay and explain which parts are BCL-owned versus Bayarcash-linked.

Use $setup-toyyibpay to integrate toyyibPay bills, callback hash verification, and idempotent settlement.

Use $setup-billplz to integrate Billplz bills, X Signature verification, and idempotent settlement.

Use $setup-fiuu to integrate Fiuu hosted checkout, Notify URL verification, Callback URL handling, and idempotent settlement.

Use $setup-senangpay to integrate senangPay hosted checkout, Callback URL verification, query status reconciliation, and idempotent settlement.

Agent Rules

Ask the agent to:

• Read existing code before adding new files.
• Read provider references/account-setup.md before explaining registration, credentials, dashboard setup, or required API keys.
• Use provider references/account-setup.md for framework setup notes, required env vars, and deployment secrets where documented.
• When referral or invite guidance exists, present it as optional and transparent; never imply it is required unless provider registration actually requires an invite.
• Keep gateway secrets server-side.
• Create a local pending payment before provider checkout.
• Verify webhook/callback signatures.
• Re-fetch payment state from the provider when possible.
• Match provider, gateway reference, amount, currency, and local payment status before marking paid.
• Make settlement idempotent.
• Add tests for invalid signatures, duplicate events, wrong amount/currency, and successful settlement.

Production Checklist

• Required environment variables are documented.
• Database migrations are included.
• Webhook URLs are configured in sandbox and live dashboards.
• Sandbox payment succeeds.
• Duplicate webhook replay is harmless.
• Fake success redirect cannot unlock paid access.
• Live and sandbox keys are separated.

Contribute A New Gateway

Contributions are welcome. Use one folder per skill.

Step 1: Pick a skill name

Use action-style names:

setup-toyyibpay
setup-senangpay
setup-stripe-malaysia

Rules:

• Lowercase only.
• Use hyphens.
• Keep it short.
• Folder name must match name: in SKILL.md.

Step 2: Create the folder

mkdir -p setup-yourgateway/references setup-yourgateway/agents

Step 3: Add SKILL.md

Minimum shape:

---
name: setup-yourgateway
description: Set up, build, debug, review, and explain YourGateway payment integrations. Use when working with checkout, payment links, callbacks, webhooks, signatures, refunds, sandbox/live setup, and payment settlement for YourGateway.

# Setup YourGateway

Use this skill for YourGateway integration work.

## Source

Read `references/yourgateway.md` before giving factual API guidance or writing integration code.

## Core Workflow

1. Identify environment: sandbox or production.
2. Create local pending payment first.
3. Create checkout/session server-side.
4. Verify callback/webhook signature.
5. Re-fetch payment state from provider when possible.
6. Settle idempotently after amount, currency, provider, and reference match.

Step 4: Add agents/openai.yaml

interface:
  display_name: "Setup YourGateway"
  short_description: "Set up YourGateway payments"
  default_prompt: "Use $setup-yourgateway to integrate YourGateway payments."

Step 5: Add references

Create:

setup-yourgateway/references/yourgateway.md

Include:

• Official docs URLs.
• Environment base URLs.
• Auth method.
• Checkout/session endpoint.
• Webhook/callback signature rules.
• Amount unit rules.
• Sandbox test notes.
• Common failure fixes.

Do not include real API keys, tokens, merchant secrets, or private customer data.

Step 6: Validate

Run validator:

python3 /home/user/.codex/skills/.system/skill-creator/scripts/quick_validate.py setup-yourgateway

If you do not have that validator, install the latest Skills CLI and at minimum verify:

npx skills@latest --version

Step 7: Test install locally

From a separate test directory:

npx skills@latest add /path/to/malaysia-payment-gateway --skill setup-yourgateway

Step 8: Open pull request

git checkout -b add-setup-yourgateway
git add setup-yourgateway
git commit -m "Add setup-yourgateway skill"
git push origin add-setup-yourgateway

Then open a pull request with:

• Gateway name.
• What products/features are covered.
• Official docs source links.
• Validation result.
• Any known gaps.
