What problem does it solve?

This Skill eliminates the risk of sensitive data leakage when sending prompts to external large language model APIs, which often contain real IP addresses, hostnames, credentials, personal identifiable information, and regulated data that must never leave the local environment.

Core Features & Use Cases

• 5-Step Anonymization Pipeline: Implements a consistent detect, replace, forward, restore workflow that anonymizes sensitive data in prompts before sending to LLMs and restores original values in responses.
• Flexible Agent Integration: Supports proxy mode, library embedding, pipeline wrapping, and multi-agent delegation patterns for seamless use with existing agent frameworks and custom LLM workflows.
• Regulated & Security Use Cases: Built for penetration testing, healthcare, legal, and financial contexts where GDPR, HIPAA, PCI-DSS, and data residency requirements mandate that sensitive data never exits local systems.

Quick Start

Use this skill to anonymize all sensitive data in your LLM prompts before sending them to external APIs, and automatically restore the original values in the LLM's response.
