DeepSeek Harness 0.2.2 RC adds nested subagents and worktree review
DeepSeek released Harness 0.2.2-rc.2 with named multi-level subagents, an optional AgentTeam panel and Git worktree review across branches, commits and file categories. It also switches default web search to DeepSeek Search, adds dynamic MCP service management and changes several plugin, sharing and computer-use interfaces.
Why it matters: The release candidate makes delegation and code review more inspectable while changing search, plugin and shared-session authority. Those migrations can improve control, but they can also silently alter which service, process or directory a session can reach.
