Team workspace vs developer harness
Tulsk is where a company defines, assigns, discusses, and reviews work. People and agents share projects, tasks, comments, files, schedules, and activity history.
The managed runtime stays behind the product surface, so teammates can use agents without installing or operating agent infrastructure.
DeepSeek Harness is the runtime and developer interface. A user selects a local code workspace, starts a session, and lets the agent inspect files, edit code, run commands, delegate work, and maintain a plan.
It does not provide a collaborative project-management layer comparable to Tulsk.
