  • After: npx skills add sd0xdev/sd0x-harness

Subcommands

Command Purpose
init First-time setup: generate AGENTS.md + install the commit-msg hook + copy scripts
doctor Verify installation integrity: files exist, AGENTS.md hash matches, and each recorded hook is active — hook bytes are sync's axis, not this one (§ doctor)
sync Re-generate AGENTS.md + update installed hooks/scripts after skill update

Default (no subcommand): init
