paddle-integration

paddle-integration is a cursor rule for Cursor from PaddleHQ/paddle-agent-skills. It costs 380 tokens per session, scanned A, original, Apache-2.0.

Coding rules for integrating Paddle, a service for selling subscriptions and one-off payments. They require checking current Paddle documentation and using its sandbox for development.

In plain words
What is it for?
Writing or changing Paddle checkout, API, SDK, and webhook integration code safely. It helps choose the right environment, verify API calls, and use the official SDK for Node, Python, Go, or PHP.
Why use it?
Paddle's APIs and SDKs change, and confusing sandbox tools with live tools can cause errors or affect real customer data. The rules also cover checking webhook signatures before trusting incoming payment events.

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

paddle-integration 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 8d 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

Paddle integration rules

When writing or modifying code that integrates with Paddle:

  • Always check current Paddle documentation via the paddle-docs MCP server before suggesting code. Do not rely on training data — the API and SDK evolve frequently.
  • When calling the Paddle API MCP (paddle-sandbox or paddle-live), always run search before execute to confirm method names and parameter shapes. Don't infer from SDK knowledge — the SDK is camelCase end-to-end, but the MCP uses camelCase method paths (client.clientTokens.create) with snake_case body params and response fields (tax_category, product_id, unit_price).
  • Default to paddle-sandbox for development. Only use paddle-live after the user has explicitly opted into operating on real data.
  • Prefer the official Paddle SDK for the language in use (paddle-node-sdk, paddle-python-sdk, paddle-go-sdk, paddle-php-sdk) over raw HTTP calls.
  • All development uses the sandbox environment. Sandbox API keys contain _sdbx; sandbox client-side tokens are prefixed with test_.
  • Always verify webhook signatures before acting on the payload. In Node, use paddle.webhooks.unmarshal(). In Python, use Verifier().verify(). In Go, use paddle.NewWebhookVerifier(). In PHP, use (new Verifier())->verify().
  • For destructive account changes (updating prices, archiving products), ask for explicit confirmation before calling destructive operations via execute, especially on paddle-live.
  • Use environment variables for API keys and webhook secrets. Never inline credentials into code.

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.
