April 2026 monthly summary: Delivered cross-app secret migration between agents app and Code.app on macOS, enabling seamless secret sharing across apps with a one-time migration flow. Achieved startup reliability by ensuring storage is initialized before secret reads and by refining the migration startup path. Improved UX by preventing unnecessary windows during migration and by correctly forwarding arguments to running instances. Strengthened reliability with timeout and disconnection handling, ensuring migration completes gracefully or exits cleanly on crash. Reduced maintenance burden via refactors: move secret sharing logic into CrossAppSecretSharing ctor, unify secret utilities in secrets.ts, and remove brittle hasAllSharedSecrets checks. These changes reduce user friction, improve startup stability, and provide a scalable foundation for cross-app integrations.
