# Cursor afterFileEdit hook.

# Counterpart of .claude/hooks/nudge-uncommitted.sh. After each
# file edit, counts uncommitted changes in the working tree.
# When the count crosses a threshold (default 4, override with
# WEBJS_COMMIT_NUDGE_THRESHOLD), injects a reminder via the
# top-level additional_context field (snake_case, unlike Claude
# Code's nested hookSpecificOutput.additionalContext).
#
# Soft nudge. Exit 0 always. Skipped on main/master and outside
# a git work tree.

REASON="You have ${CHANGED} uncommitted changes on '${BRANCH}'. The webjs convention is small, focused commits per logical unit (one feature, one fix, one rename, one doc rewrite). Before continuing with more edits, group the current changes into a meaningful commit. See AGENTS.md \"Git workflow\" for the rule and the rationale. To raise the threshold for this hook in long-running tasks, set WEBJS_COMMIT_NUDGE_THRESHOLD."
