Recommended action: Use `exit 2` (or a JSON blocking decision) for policy hooks; verify the path and chmod +x; watch for the notice on first run.
Option: Use `exit 2` (or a JSON blocking decision) for policy hooks; verify the path and chmod +x; watch for the notice on first run. [evidence: official_recommended_action]
Applies when: PreToolUse/UserPromptSubmit command hook intended to block an action
Steps:
1. Change the hook to `exit 2` with the reason on stderr, or print a JSON decision
2. Use an absolute path or ${CLAUDE_PROJECT_DIR}; consider exec form (`args`) to avoid shell quoting
3. chmod +x the script
4. Test manually: echo sample JSON | ./hook.sh; echo $?
5. Enable --debug-file to see full stderr
Expected: The error no longer appears.
