深度体验DeepSeek Harness，我原谅它涨价了

TL;DR - DeepSeek released and open-sourced DeepSeek Harness (DSH), a developer-focused coding-agent runtime with a highly modular plugin architecture. Its openness could enable extensive customization and a community ecosystem around agent tooling and self-improvement.

• Models, tools, policies, storage, and context management are replaceable plugins; more than 100 plugins are included.
• Four presets cover full coding, TypeScript-composed operations, minimal benchmarking, and runtime/plugin development.
• Event-level trajectory replay exposes agent actions, failures, token usage, and cache performance for debugging.
• The reviewer found DSH stronger than Codex on some long-running tasks, but this was anecdotal testing rather than a formal benchmark.
