# MSOS pre-commit hook — keeps derived files in sync automatically.
#
# On every commit it regenerates and stages:
#   - the News hub grid + homepage "Latest news"   (tools/build_listings.py)
#   - /llms.txt and /links-for-bots/               (tools/build_botlinks.py)
# so adding a blog post or an event/project flows through to News, the homepage
# and the bot pages without any manual command.
#
# It never blocks a commit: if Python or a generator fails, it warns and lets
# the commit proceed.
#
# Activate once per clone:   git config core.hooksPath tools/git-hooks
# ---------------------------------------------------------------------------
