DeepSeek Harness
DeepSeek Harness is the engine behind HarnessLaunch: a coding agent built on DeepSeek models that plans a task, inspects your codebase, makes changes, and verifies its own work.
How the agent works
- Explore — reads the relevant files and builds a picture of your project.
- Plan — breaks the task into concrete steps before editing anything.
- Act — makes the changes, running commands and editing files as needed.
- Verify — checks its own output and reports what it changed.
Built for the desktop
HarnessLaunch runs natively on Windows. There is no container to configure and no server to keep alive — the harness works directly against the projects already on your machine.
Where it stops
The agent stays inside the workspace you opened. Operations that would reach outside it require your explicit approval, and irreversible actions are surfaced for review first.
