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).
