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

1. Clone the repository: git clone [e-mail]:AndrewAndrewsen/MessageGuard.git.
2. Navigate to the directory. The skill is dependency-free, relying only on the Python standard library.
