Custom Configuration Directory

By default, Codex stores its configuration and session data in ~/.codex. If you have configured a custom location using the CODEX_HOME environment variable, Relipa Kanban will automatically detect and use that location. 
# Example: Using a project-specific Codex configuration
export CODEX_HOME=/path/to/custom/codex
npx <relipa-kanban-cli>
This is useful for:
  • Project-specific Codex profiles
  • Separating work and personal configurations
  • Custom automation setups
