+
+## Claude Code Attribution Hook
+
+Initiated implementation of a PreToolUse hook to block git commits containing Claude Code's automatic "Co-Authored-By: Claude <noreply@anthropic.com>" attribution. The plan involves two tasks:
+
+1. **Hook Script Creation** - A bash script at `~/.claude/hooks/block-coauthor.sh` that reads JSON from stdin, extracts the command via `jq`, checks for `git commit` operations, and scans for the Co-Authored-By pattern (case-insensitive). Denies execution if found, allows otherwise.
+
+2. **Settings Registration** - Adding a PreToolUse entry to `~/.claude/settings.json` hooks object with matcher "Bash", 5-second timeout, and status message.
+
+Examined existing settings.json structure which already has hooks configured for SessionStart, UserPromptSubmit, and SessionEnd via signet commands. The PreToolUse hook will follow the same pattern structure.
+
+Session ended after reading settings.json; implementation of the hook script and settings update pending.
