# Fetch npm-global CLIs as .tgz tarballs for offline install on the ISO target.
#
# These three packages are agent runtimes the firstboot installer will
# `npm install -g` from local tarballs (no network needed):
#
#   @anthropic-ai/claude-code   — Claude Code CLI (agent harness)
#   @google/gemini-cli          — Gemini CLI (alt agent)
#   @mariozechner/pi-coding-agent — pi CLI (used by clawdie-ai + paperclip adapters)
#
# Notes:
#   - Codex is shipped via the FreeBSD `codex` pkg (see pkg-list-host.txt),
#     not via npm — kept out of this bundle on purpose.
#   - opencode + cursor have no working FreeBSD distribution (upstream gap).
#   - Output is dual-purpose: bundled into the ISO and used by firstboot.
#
# Usage:
#   ./scripts/fetch-npm-globals.sh           # fetch into tmp/npm-globals/
#   OUT_DIR=/some/path ./scripts/fetch-npm-globals.sh
