Claude Code writes tool permission rules that didn't match the regex pattern. Specifically, Claude Code writes permission rules with nested parentheses.
Normally, left/right parentheses matching is beyond the capabilities of regex validation, but Claude Code escapes the nested parentheses with a backslash. For example:
`Bash(python3 -c "import sys,json; d=json.load\(sys.stdin\); print\('OK' if d.get\('id'\) else d\)")`
