What's Wrong?

When approving a git commit command that uses HEREDOC format, a fragment of the commit message content is incorrectly captured and added
to the permissions.allow array in .claude/settings.local.json, corrupting the file with invalid data.

The malformed entry looked like:
"Bash(3\")\n- Identified C-rule issue: universal rules flagged incorrectly\n\n🤖 Generated with Claude
Code\n\nCo-Authored-By: Claude <noreply@anthropic.com>\nEOF\n)\")"

What Should Happen?

The permission should capture a valid command pattern like "Bash(git commit:*)" instead of a fragment of the HEREDOC content.

Steps to Reproduce

1. Use Claude Code to make a git commit with HEREDOC message format:

git commit -m "$(cat <<'EOF'
Commit message here

🤖 Generated with Claude Code

Co-Authored-By: Claude <noreply@anthropic.com>
EOF
)"

1. Approve the command when prompted
2. Check .claude/settings.local.json - a corrupted entry appears in permissions.allow
