Features
Section titled “Features”Review intent, not just code
Section titled “Review intent, not just code”Each OpenSpec change produces a spec delta that captures the change in requirements of the system. This makes it easy for developers to understand how they’re modifying the system and what will need to change.
### Requirement: Session expiration The system SHALL expire sessions after a configured duration. The system SHALL support configurable session expiration periods.#### Scenario: Default session timeout- GIVEN a user has authenticated - WHEN 24 hours pass without activity - WHEN 24 hours pass without "Remember me"- THEN invalidate the session token #### Scenario: Extended session with remember me - GIVEN user checks "Remember me" at login - WHEN 30 days have passed - THEN invalidate the session token - AND clear the persistent cookieComing Soon: Workspaces
