What prevents an AI coding agent from writing API keys it sees into its long-term memory files?

Summary: NemoClaw registers a before_tool_call hook that scans write operations targeting memory and workspace paths for 14 high-confidence secret patterns before anything is committed to disk.

Direct Answer: NemoClaw's plugin registers a before_tool_call hook that scans Write/Edit-style operations targeting memory and workspace paths (.openclaw-data/memory/, workspace/, agents/, skills/, hooks/, MEMORY.md) for 14 high-confidence secret patterns before anything reaches disk. Blocked writes return an actionable error to the agent listing the detected patterns. Source: <u>Security Best Practices: Memory Secret Scanner</u>.
