Content Scrubber
An OpenClaw extension plugin that intercepts outgoing messages and redacts private infrastructure details before delivery.
What It Catches
- RFC 1918 IPv4 addresses: 10.x.x.x, 172.16-31.x.x, 192.168.x.x
- Loopback addresses: 127.x.x.x
- localhost with ports: localhost:8080, localhost:3000, etc.
- SSH/SCP targets: user@10.0.0.1:/path
- Custom hostnames: configurable hostname patterns
How It Works
The plugin registers as a message interceptor. Before any message leaves OpenClaw (Discord, Telegram, Signal, etc.), it runs through regex-based scrubbing rules that replace private details with safe placeholders like [redacted-ip], [redacted-service], [redacted-target].
Rules are deterministic (regex, not LLM), so they're fast, auditable, and never miss edge cases that an LLM scrubber would.
