DeerFlow

DeerFlow is an open-source long-horizon agent harness for research, coding, content generation, sandboxed execution, memory, tools, skills, subagents, and message gateways. Why it matters: Long-running agents need more than a prompt: they need orchestration, tool boundaries, state handling, and recovery patterns. DeerFlow is a useful reference architecture for how those pieces are being packaged in open source.

Try this: Review the README and architecture, then compare its memory, sandbox, and subagent design against one existing agent workflow before adopting the full stack.
