 ### Features Added
 
 - Updated `IndirectAttack` risk category for RedTeam to `IndirectJailbreak` to better reflect its purpose. This change allows users to apply cross-domain prompt injection (XPIA) attack strategies across all risk categories, enabling more comprehensive security testing of AI systems against indirect prompt injection attacks during red teaming.
+- Added `TaskAdherence`, `SensitiveDataLeakage`, and `ProhibitedActions` as cloud-only agent safety risk categories for red teaming. 
 
 ### Bugs Fixed
