# Symlinks private skills from the Obsidian vault into .claude/skills/.
# Safe to re-run.
#
# Private skills live in the Obsidian vault (not in this repo) because they
# contain personal preferences, business data, or sensitive references.
# The symlinks here let Claude Code load them as if they were local skills.
#
# Required env var:
#   SH_PRIVATE_SKILLS_DIR — absolute path to the folder in the Obsidian vault
#                           that holds the private skill subfolders.
#
# Example:
#   export SH_PRIVATE_SKILLS_DIR="$HOME/Documents/nvALT/Simple History/claude-skills"
#   ./scripts/setup-private-skills.sh
#
# Add the export to your shell profile (.zshrc / .bashrc) to make it permanent.
