Introducing User-Defined Redaction

Marvin introduces a new feature in the Entire CLI, allowing users to implement user-defined redaction to protect sensitive information within agent sessions. This feature complements the default automatic redaction of detected secrets by providing an extra layer of customization for safeguarding internal tokens, customer names, project identifiers, and other private data. Users can create custom redaction rules using Go/RE2 regular expressions, which can be applied to transcript and checkpoint metadata but not to raw source-file snapshots. These rules can be configured in settings files, with options for sharing through reusable YAML or JSON rule packs, while keeping personal rules out of Git. The update aims to enhance control over data privacy and security, with further details available in the Security & Privacy documentation.
