Distil PII Redactor: an OpenClaw Skill

Locally redact PII from text using a fine-tuned 1B parameter model. Your sensitive data never leaves your machine — the frontier LLM powering OpenClaw never sees the raw text. Only the local model processes it, and only the redacted output is returned.

Prerequisites

llama.cpp installed (brew install llama.cpp on macOS, or build from source)
Python 3
~5 GB disk space for the GGUF model

Install from ClawHub

clawhub install distil-open-claw-pii

Or install directly in your OpenClaw chat:

/install distil-open-claw-pii

Quick Start with OpenClaw

Install the skill (see above), or copy this folder to ~/.openclaw/skills/distil-pii-redactor/
Tell OpenClaw: “set up the PII redactor” (this downloads the model and starts the local server)
Use it: “redact this: Hi I’m John Smith, john@smith.com, call me at 555-123-4567”

Standalone Usage (without OpenClaw)

# One-time setup: download model + start server
bash scripts/setup.sh

# Redact text (via argument or stdin)
python scripts/redact.py "Hi, I'm John Smith. Reach me at john.smith@example.com or 555-123-4567."
cat examples/sample_input.txt | python scripts/redact.py

# Stop the server when done
bash scripts/stop.sh
