# Install Domna's curated skill set globally (~/.claude).
#
# 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. Copies the pinned skills-lock.json from agentic-toolkit to ~/.claude.
#   2. Parses it and runs `skills add --global` per source so all skills land
#      in ~/.claude/skills (user-level, available in every repo).
#
# Note: `skills experimental_install` would be the natural fit but it only
# restores at project scope — confirmed empirically that running it against
# a global lock prints "No project skills found" and exits 0, installing
# nothing. So we drive `skills add --global` from the lock instead.
#
# Logs verbose output to $HOME/.claude/agentic-toolkit-setup.log so failures
# under postCreateCommand or `| bash` are inspectable after the fact.
