#
# Sourced by install-plugins.sh (Step 8.6), update-all.sh (7.3b) and
# doctor.sh. The pack is machine-owned: cloned from upstream and moved
# into skills-external/higgsfield-* (gitignored), then linked on demand by
# lib/toggle-external.sh. It is listed in neither link.sh nor any profile:
# either would re-enable a parked pack on every run (BDR-093).
# ============================================================

# Upstream skills repo, single source for both installers. An env value
# wins so the hermetic suite can point it at a local fixture repo.

# Prints the number of skills synced. Returns 1, existing copies untouched,
# when the clone fails or upstream holds no higgsfield-*/SKILL.md. A parked
# skill (skills-disabled/<name>, a symlink to the source path) stays parked.
