CLI Reference

Complete reference for the labhit command-line tool.

Global Options#

--verbose, -v     Enable debug-level logging
--config, -c      Path to engine config (default: .labhit/config.yaml)
--help, -h        Show help

Pipeline Commands#

labhit run#

Execute a pipeline.

labhit run [OPTIONS]

Options:

Examples:

labhit run                              # Run full pipeline
labhit run --stage build                # Run build + its dependencies
labhit run --dry-run                    # Preview the execution DAG
labhit run -f ci/release-pipeline.yaml  # Use a custom pipeline file

Behavior:

1. Parses pipeline YAML and builds the dependency graph
2. Detects Docker availability for sandbox: stages
3. Loads extensions from .labhit/extensions/
4. Loads policies from .labhit/policies/ (if present)
5. Dispatches stages in parallel where dependencies allow
6. Prints colored status for each stage
7. Exits with code 0 on success, 1 on failure
