What does the Polar Integration Validator check?

It checks webhook endpoint existence, signature verification (polar.webhooks.verify), environment variables, and database schemas for Polar.sh compatibility.

When does this skill activate?

It triggers automatically when you modify webhook files, subscription code, environment variables, or configuration files like wrangler.toml.

Can it block deployments?

Yes, it can identify P1 critical issues that should be resolved before deployment to ensure billing security and functional stability.

Does it support custom webhook logic?

Yes, it validates standard patterns and escalates to a billing specialist for complex, multi-tenant, or usage-based billing scenarios.

安全与测试

Validates and secures Polar.sh billing integrations by checking webhooks, signatures, and environment configurations.

关于

The Polar Integration Validator is a specialized Claude Code skill designed to ensure the integrity and security of Polar.sh billing implementations within your codebase. It autonomously monitors for changes in webhook handlers, subscription logic, and configuration files like wrangler.toml, providing real-time feedback on critical issues such as missing signature verification, incomplete event handling, and database schema misalignments. This skill helps developers avoid common pitfalls in subscription-based services by enforcing best practices for security, error handling, and middleware protection.
