Show HN: A 60-line PreToolUse hook that stops Claude Code from editing your .env
guard.py — stop it from touching the files that matter CLAUDE.md is advice. The model reads it, the conversation gets long, the rule loses priority, and it edits the file anyway. Blocked by guard.py: .env It matches the pattern '.env' listed in .claude/protected.txt.

guard.py — stop it from touching the files that matter CLAUDE.md is advice. The model reads it, the conversation gets long, the rule loses priority, and it edits the file anyway. That is not a prompting problem. No wording fixes it. This is not advice. It runs before the tool call and refuses it. Blocked by guard.py: .env It matches the pattern '.env' listed in .claude/protected.txt. The model never gets to write. It gets told why, and moves on.
