verl-agent vs deepseek-harness-handbook

verl-agent: `verl-agent` extends veRL to train LLM agents using reinforcement learning, featuring a novel step-independent multi-turn rollout mechanism. This design ensures high scalability for long-horizon tasks by allowing customizable per-step input structures and memory management.; deepseek-harness-handbook: This is an agent-first, source-backed field guide to DeepSeek Harness, a composable agent runtime connecting LLM providers, tools, and user interfaces. It offers canonical guides, troubleshooting runbooks, and architectural explanations for building, operating, and extending AI agents.
