To prevent Claude Code from overwriting identity files, you need a PreToolUse hook that blocks destructive write operations on critical configuration files. This Skill enforces those rules, stopping the Write tool from replacing files like CLAUDE.md and SOUL.md.

Context compaction degrades AI behavioral rules, but technical guardrails survive it. This Skill operates as a Node.js hook, ensuring file protection persists even when an AI agent's internal instructions degrade after context compaction.

You can limit destructive edits by enforcing a net line removal threshold. This Skill blocks the Edit tool if it attempts to remove more than two net lines from a protected file or performs a large content replacement.

Yes, you can use this file protection hook with OpenClaw agents. It operates as a lifecycle hook for OpenClaw, enforcing edit blocking and preventing destructive writes on critical AI identity files.

The best way to stop AI agents from replacing SOUL.md is to block large content replacements at the tool level. This Skill blocks operations that attempt to overwrite protected files, forcing the AI to append or make minor edits instead.

A Node.js hook provides technical file protection that persists regardless of context state, whereas prompt instructions degrade after context compaction. This hook directly blocks the Write and Edit tools from executing destructive operations on protected files.
