What Is Output Filtering?

Output Filtering is a panel on the Guard Rails tab meant to scrub sensitive data from a tool's response before it reaches the AI — masking a field, removing it, or redacting a regex pattern. It's visible and interactive today, but not yet wired to the backend, so filters you define aren't actually applied.
