# files added without going through the formatter (the most common cause
# of CI format-check failures) get fixed silently here. The format
# scripts already respect .prettierignore so the agent-native submodule
# and generated files are untouched.

# NOTE: re-adding files pulls in any unstaged hunks from a partially
# staged file. Stage cleanly if that matters to you.
