# install_skills.sh
# Deploys skills from the Exocortex repo to /a0/usr/skills/ (persistent user space).
# Three sources, applied in order (later sources win on conflict):
#
#   agent_skills/   — skills the agent created and we've verified; restored on every
#                     fresh container so the agent starts with its accumulated library
#   skills/         — Exocortex-maintained overrides (e.g. create-skill path fix)
#
# On live (non-fresh) containers, also migrates any new agent-created skills that
# landed in the ephemeral /a0/skills/ path and aren't yet in the repo.
#
# Safe to re-run at any time (idempotent).
