DeepSeek Harness 0.2 Released with Desktop Clients, Optional Bundles, and Async Mode

DeepSeek harness 0.2 introduces significant architectural changes and new platform support, focusing on improving the Agent Runtime's production readiness.

New Desktop Clients

Official Windows and macOS clients are now available, though Linux remains unsupported. The release supports account login, indicating potential upcoming paid plans.

Architectural and Runtime Improvements

• Optional Bundle Architecture: The Schedule feature (session-local delayed/timed/interval reminders) has been removed from the default set and made an explicit Optional Bundle. This separates "installed" from "enabled" features, marking the first systematic use of the Profile and Bundle model for official features.
• Async Question Mode (Experimental): The "Ask the user" interaction is no longer a hard synchronous block. After a timeout, the Agent can continue working while waiting for user input, introducing asynchrony between interaction and execution.
• Windows Sandbox Improvements: A new permission-diagnosis skill detects common "Access Denied" causes and performs backed-up, recoverable permission fixes after user authorization, providing a reliable recovery path instead of blind retries.

Model Layer Updates

• Web Search: DeepSeek-account sessions can now use Web Search without requiring an extra API key.
• Catalog Changes: The third-party model catalog has been updated with some old IDs removed. Long model lists now support fuzzy search and keyboard navigation.
