What problem does it solve? Environment variables are often undocumented, unvalidated, or accidentally committed to repositories, causing production crashes, leaked secrets, and painful onboarding. This Skill audits your entire env var setup and produces a scored report with prioritized fixes. ## Core Features & Use Cases - Eight-dimension audit (ENV1-ENV8): Checks variable completeness, unused vars, startup validation, secret exposure, environment parity, type safety, default values, and documentation, with critical gates that fail the audit on committed secrets or missing validation. - Multi-stack detection: Recognizes Node.js (process.env), Python (os.environ), Vite (import.meta.env), Next.js (NEXT_PUBLIC_), Cloudflare Workers, and Docker Compose patterns automatically. - Scored report with remediation roadmap: Outputs a 0-100 score, a variable coverage matrix, severity-sorted findings with file:line citations, and quick-win to medium-term fix plans. - Use Case: Before a production deploy, run the audit to catch a hardcoded API key in a NEXT_PUBLIC_ variable and a missing .env.example, then follow the remediation roadmap to add Zod schema validation at startup. ## Quick Start Run the env-audit skill on my project to check for exposed secrets, missing validation, and undocumented environment variables.
