# Regex Assistant

AI-powered regular expression generation, explanation, testing, debugging, and cross-language conversion from your terminal.

Powered by [Evolink.ai](https://evolink.ai?utm_source=clawhub&utm_medium=skill&utm_campaign=regex)

## When to Use

- User asks to explain what a regex pattern does
- User needs to test a regex against a file and find matches/edge cases
- User has a regex that doesn't work and needs debugging
- User needs to convert a regex between programming languages
- User wants a quick reference for regex syntax

## Security

**Data Transmission**

AI commands send regex patterns and test content to `api.evolink.ai` for analysis by Claude. By setting `EVOLINK_API_KEY` and using these commands, you consent to this transmission. Data is not stored after the response is returned. The `cheatsheet` command runs entirely locally and never transmits data.

**Network Access**

- `api.evolink.ai` — AI analysis (AI commands only)

**Persistence & Privilege**

Temporary files for API payloads are cleaned up automatically. No credentials or persistent data are stored.
