```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise.

## Documentation

### MessageGuard: Outgoing Message Filter Skill

Purpose: MessageGuard filters outgoing text to prevent secret leaks and sensitive data exposure by using pattern-based detection and configurable actions (mask, block, or warn).

### Advanced Configuration Options:

mode: Determines the global action for matched patterns. Options are:

mask: Replace sensitive data with the mask_char.
block: Prevent the message from being sent entirely.
warn: Allow the message but generate warnings.


mask_char: The character(s) used to replace sensitive content when mode is set to mask.
patterns: Define or customize regex-based detections. Built-ins exist for API keys, credentials, and more (e.g., AWS keys, JWTs). Add new patterns based on your requirements.
logging: Enable detections to be logged as structured JSON for monitoring, debugging, or compliance needs. Configure the log_path for the output location.
Custom Patterns: Users can define their custom patterns to override built-ins or extend functionalities. This supports regex and granular action control (mask, block, warn).

Installation

Clone the repository: git clone git@github.com:AndrewAndrewsen/MessageGuard.git.
