Will EnvGuard slow down my VS Code?

No. It performs pattern matching on your .env file in real-time, but that's computationally trivial. The overhead is negligible compared to other extensions like Copilot or linters.

Can it detect every type of secret?

Not every one — no tool can. It detects 30+ common patterns (AWS, GitHub, Stripe, Google, Slack, SendGrid, Firebase, JWT, etc.). For hyper-specific proprietary tokens, schema validation catches missing variables. Think of it as 95% automatic, 5% up to you.

Does it work with GitHub Actions or CI/CD?

It's an editor extension, so it only runs locally. For CI/CD, use post-commit scanners like git-secrets or TruffleHog alongside EnvGuard. Think of this as your first line of defense, not your only one.
