CLI Reference

Skern provides a set of commands for managing agent skills across platforms. Every command supports --json for machine-readable output and --quiet for silent operation.

Pages

• Commands — full reference for every command including flags and usage examples.
• Validation — rules enforced by skern skill validate and during skill creation.
• Overlap Detection — fuzzy matching, similarity scoring, and capacity thresholds.

Command Groups

skern skill --help splits subcommands into two groups:

• Registry commands — manage skills in skern itself (create, import, edit, remove, list, show, search, validate, version, diff, recommend).
• Platform commands — deploy registered skills to a platform (install, uninstall).

The registry holds the canonical skill. Install copies the skill into a platform's directory; uninstall removes the platform copy without touching the registry; remove deletes the skill from the registry entirely.

Global Flags

Flag	Description
--json	Output in JSON format
