Expanso Pii Detect

What This Skill Does

The Expanso Pii Detect skill, developed by aronchick, serves as a powerful utility for identifying and sanitizing personally identifiable information (PII) within textual data. Whether you are dealing with log files, customer feedback, or sensitive communication strings, this skill leverages the Expanso Edge infrastructure to perform high-speed, local detection of patterns that represent sensitive data such as social security numbers, email addresses, phone numbers, or credit card digits. By integrating this into your OpenClaw workflow, you ensure that sensitive information is properly flagged before it is processed by downstream AI models or stored in external databases.

Installation

To begin using this skill, you must first ensure you have the Expanso Edge environment configured. Ensure the expanso-edge binary is accessible in your system PATH. Once ready, execute the following command in your terminal to install the skill via the OpenClaw hub:

clawhub install openclaw/skills/skills/aronchick/expanso-pii-detect

After installation, you can verify the setup by reviewing the skill.yaml configuration file included in the package. This file defines the necessary inputs and outputs required to interface with your local pipelines.

Use Cases

This skill is indispensable for compliance-heavy environments. Common use cases include:

1. Pre-processing logs for GDPR or HIPAA compliance by redacting user data before indexing.
2. Securing AI prompts by stripping PII from raw text inputs before sending data to third-party LLM APIs.
3. Automated auditing of datasets to ensure no unintended leakage of sensitive corporate or personal info exists in your repositories.

Example Prompts

1. "Scan the following raw log segment for any exposed customer names or contact info: [log_data]"
2. "Process my recent support tickets and alert me if any credit card numbers are visible in the body text."
3. "Help me sanitize this company database export by masking all email addresses found within the document."

Tips & Limitations

To maximize effectiveness, ensure your input data is relatively clean of formatting issues that might obfuscate PII patterns. Note that while this tool is excellent for detection, it is intended to be a part of your security stack, not a complete replacement for robust encryption or organizational privacy policies. For the best results, use the MCP pipeline mode when you require a persistent server-side connection to handle continuous streams of data, or utilize the CLI pipeline for one-off batch processing of files.
