做好，再让开发者扩展它”。它首先提供一个完整、成熟、面向软件开发的 Agent Engine，然后通过 CLAUDE.md、Skill、MCP、Hook、Subagent 和 Agent SDK 让开发者逐渐增加能力。这种路线最大的优势是产品体验好，开发者不需要理解 Harness 内核，也能直接完成真实代码修改、Debug、测试和重构。</span></p><p style="color:

2px;padding-bottom: 2px;padding-left: 0px;padding-right: 0px;"><span>Codex 的路线更接近“先建立稳定 Runtime，再让不同客户端和工作流围绕 Runtime 构建”。Codex Core、Thread、App Server、Sandbox 和 Approval Policy 形成了比较明确的系统边界，使 CLI、IDE、Desktop、Automation 和其他 Agent Client 可以建立在同一套底层 Runtime 上。这种架构很适合未来构建 Coding Agent Platform，而不仅仅是一个命令行工具。</span></p><p style="color: rgb(58, 58, 58);font-size: 16px;line-height:

0px;"><span>DeepSeek Harness 的路线则更接近“不要过早定义唯一的 Agent Core，而应该提供组合 Agent Runtime 的机制”。它尝试把 Model、Tool、Session、Sandbox、Prompt、Agent 和 Agent Loop 等组件全部放入可组合体系，让研究者能够重新定义 Agent 的执行逻辑，而不是只扩展一个已经固定的 Agent。</span></p><p style="color: rgb(58, 58, 58);font-size: 16px;line-height: 1.7;letter-spacing: 0em;text-align: left;text-indent: 0em;margin-top: 10px;margin-bottom: 0px;margin-left: 0px;margin-right: 0px;padding-top: 2px;padding-bottom: 2px;padding-left: 0px;padding-right: 0px;"><span>Claude Code 使用 CLAUDE.md、Memory、Skills 和 Subagent Context 管理它；Codex 使用 AGENTS.md、Skills、Thread 和 Compaction 管理它；DeepSeek Harness 更进一步，通过 Session Event Stream 派生 Model Messages，把 Context Construction 本身纳入 Runtime。</span></p><p style="color: rgb(58, 58, 58);font-size: 16px;line-height:

0px;"><span>Claude Code 通过 MCP、Permission、Sandbox 和 Hooks 管理这些能力，Codex 把 Tool Execution 与 Approval 和 Sandbox 纳入 Runtime，DeepSeek Harness 则进一步把 Tool Registry 和 Tool Lifecycle Event 本身设计成可组合能力。虽然三者具体实现方式不同，但最终都在说明同一个趋势：Agent Tool 已经不再只是一个函数，而是一套受 Runtime 管理的执行能力。</span></p></section>                            <div class="content-mask">
