Review Risk Analysis

Envark automatically classifies environment variables by risk level:
  • Critical — Used but not defined, will cause runtime crashes
  • High — Secret-like names in committed files
  • Medium — Multiple usages without defaults
  • Low — Undocumented or unused variables
Run /risk to see detailed risk analysis with file locations and usage counts.
4

Generate .env Template

Auto-generate a complete .env.example file from your codebase:
envark generate
Envark extracts all environment variables, adds comments with usage context, and groups related variables together. Perfect for onboarding new developers.
