Validates .env files and environment variable configurations against project requirements. Checks for missing required variables, type mismatches, insecure defaults, unreferenced variables, and common configuration errors. Compares .env against .env.example, code references, and deployment manifests. Produces a structured validation report with severity-ranked findings. Triggers on: "validate env file", "check environment variables", "env file audit", "missing env vars", "env validation", "check .env", "environment config check", "validate configuration", "env file review", "dotenv validation". Use this skill when verifying environment configuration completeness and correctness before deployment or after onboarding. NOT for secret scanning (use repo-sentinel or secret-scanner). NOT for general config file editing (use filesystem skill).

DO NOT USE FOR: detecting statics (use detect-static-dependencies), migrating call sites (use migrate-static-to-wrapper), general interface design not about testability.
