# Install Domna's curated skill set into the current repo.
#
# Run from the root of the target repo:
#   curl -fsSL https://raw.githubusercontent.com/Hestia-Homes/agentic-toolkit/main/setup.sh | bash
# Or, if you've cloned agentic-toolkit:
#   bash /path/to/agentic-toolkit/setup.sh
#
# What this does:
#   1. Drops the pinned skills-lock.json from agentic-toolkit into the target repo.
#   2. Runs `skills experimental_install` to restore the exact pinned versions
#      of Matt Pocock's skills + Domna's own skills (Hestia-Homes/agentic-toolkit).
#
# To upgrade skills across all Domna repos:
#   - In agentic-toolkit, re-install the skills you want, then commit the
#     resulting skills-lock.json (this script reads from that file).
#   - Devs re-run setup.sh in their target repos.

  1. Run /setup-matt-pocock-skills (one-time per repo) to record the issue
     tracker, triage labels, and domain-doc layout.
