DeepSeek releases open-source Super-Agent, an always-on AI coding agent rivaling Claude Code

DeepSeek's Harness team has released Super-Agent, an open-source AI coding agent architecture on GitHub under the MIT license, positioned as a competitor to Anthropic's Claude Code. Unlike Claude Code's terminal-driven workflow, Super-Agent runs as a background service that monitors chats, GitHub pull requests, and CI/CD pipelines, and it can act on events without being explicitly invoked. Its design splits work between a lightweight Router that triages triggers, Workers that execute coding tasks in parallel, and a Watchdog that prevents stalled or looping tasks. DeepSeek's synthetic benchmarks reported a 95th-percentile completion time of 15.7 minutes, versus 29.5 minutes for traditional single-session subagent approaches. The system also includes permission tiers, including an observe mode that logs intended actions without executing them.
