Fast interactive work
Use DeepSeek Harness for implementation questions, code review, debugging, and focused technical decisions in a browser workspace.
DeepSeek Harness
DeepSeek Harness in a durable browser workspace.
Run DeepSeek Harness in onesagent when you need fast DeepSeek-native conversations without giving up project context, durable jobs, replay, and recoverable outputs.
The runtime stays native. The workspace stays reliable.
Long-running follow-through
Keep job state, assistant replies, generated files, and run events attached to the session after a reload or worker handoff.
Scoped provider access
The Worker owns the provider connection. Browser clients receive hosted session facts rather than provider credentials.
When teams use it
01
Implementation loops
Turn a product request into a code change, inspect the outcome, then continue the same project-scoped conversation.
02
Debug and incident follow-up
Keep a diagnosis, runtime evidence, and the next remediation turn together instead of losing the thread in a terminal.
03
Research-backed delivery
Use the Harness for concise technical work while onesagent keeps durable files, artifacts, and replayable activity around the result.
Current boundary
- DeepSeek Harness execution is owned by the Worker; browser and Gateway do not expose the provider key.
- Reasoning traces are not forwarded to the browser. The session records safe assistant output, job state, events, and artifacts.
- A restarted native process rehydrates the hosted conversation context so the durable session remains the product boundary.
DeepSeek Harness FAQ
What model is selected by default?
The hosted DeepSeek Harness lane defaults to the DeepSeek Flash model profile, while project settings can select a supported alternative.
Is this only a chat wrapper?
No. The browser chat is backed by a durable session, Worker-managed runtime execution, replayable events, and session-scoped workspace custody.
Can I keep working after a refresh?
Yes. onesagent reloads the persisted session, messages, jobs, and runtime evidence instead of relying on one browser request to stay open.
