# Commit tracked changes at the end of every session so work is durable across

# artifacts (screenshots, logs, scratch files) shouldn't land in history. The
# agent is expected to `git add` new source files itself per CLAUDE.md.

# Fails silently if commit can't be made (no git user.name, hook rejects, etc);
# check `git log` periodically when relying on this as a backstop.
