A DeepSeek-native lane with a durable session boundary
DeepSeek Harness keeps its own conversational and tool loop. onesagent keeps the browser workspace reliable by retaining the session, jobs, safe output, artifacts, and replay around the runtime.
runtime support
Run DeepSeek Harness in a durable browser workspace
Use the DeepSeek Harness runtime with DeepSeek Flash selected by default while keeping the session, job, artifacts, and replay inside a hosted project workspace.
Fast technical work without a disposable browser chat
DeepSeek Flash is the default model profile for focused implementation, debugging, code review, and technical follow-up. A reload does not discard the project-scoped context or the work already produced.
Provider access remains inside the Worker boundary
The hosted Worker owns provider configuration and execution. Browser clients receive session state and safe results, not the underlying provider credentials.
