Command-line reference

The xylem executable currently exposes the run command:

xylem [OPTIONS] [COMMAND]
xylem [OPTIONS] run [RUN OPTIONS]

Global options include verbosity flags and -t, --threads <N>. The worker count defaults to 10, must be greater than zero, and limits Xylem’s Rayon work rather than threads created by child programs.

The run command accepts:

• --config <PATH> for a JSON or YAML configuration;
• --input <LIST> for comma-delimited workflow inputs;
• --dry-run to describe work without executing module commands;
• --offline to prohibit remote acquisition;
• --skip-verify-checksum and --skip-verify-requirements for explicit troubleshooting bypasses; and
• reporter and output options reserved for structured result presentation.

When --config is omitted, Xylem looks for config.json in the current directory. Run the generated help for version-specific spelling and defaults:

xylem --help
xylem run --help
