Environment variables

Command-line flags win over these, and these over config.yaml.

Variable	Used for
CODEFLOWER_CONFIG	the config directory (default ~/.codeflower)
CODEFLOWER_AGENT	the default --agent
CODEFLOWER_ENGINE	the default --engine: auto, docker, podman or apptainer
CODEFLOWER_IMAGE	the default --image
CODEFLOWER_IMAGE_TAG	the default --image-tag
CODEFLOWER_IMAGE_DIR	where Apptainer images are kept (default ~/codeflower/images)
CODEFLOWER_AGENTS_DIR	where Claude Code is downloaded to (default ~/codeflower/agents)
DOCKER_HOST	the Docker engine to use
HTTPS_PROXY, HTTP_PROXY	the proxy a network-isolated sandbox’s traffic goes through

The install scripts read CODEFLOWER_VERSION (a release to install instead of the latest) and CODEFLOWER_INSTALL_DIR (where to install).

The app also reads batch schedulers’ variables (Slurm, PBS, LSF, Grid Engine, HTCondor) to find a job’s allocation, and passes it to the agent.
