Show HN：Recurse——更快开发和部署专用 Agent

英文标题：🔶 Show HN: Recurse – Develop and deploy specialist agents faster

Recurse 展示了一套用于开发、评估和部署专用 Agent 的命令行工作流。演示中，Agent 可调用搜索与验证工具，并通过规划、测量、修订和反思循环持续优化；样本评估记录显示，得分 0.91 的结果被保留，而得分 0.87 的结果被丢弃。该工具还可将 Agent 部署为 MCP 服务，并通过 `codex mcp add recurse` 和 `claude mcp add recurse` 接入 Codex 与 Claude。对开发者而言，这意味着可将 Agent 的工具注册、输入输出校验、测试和部署流程组织为可重复执行的工程化链路。

运行 Agent：调用搜索工具、执行验证并返回结果，状态显示为 ready。

text $ recurse run ./agent ── ⚡ tools.search() ── │ ├── verify() │ └── return result ── > _ ready ── ░▒▓ ██ ▓▒░ ── $ recurse run ./agent ── ⚡ tools.search() ── │ ├── verify() │ └── return result ── > _ ready ── ░▒▓ ██ ▓▒░ ── $ recurse run ./agent ── ⚡ tools.search() ── │ ├── verify() │ └── return result ── > _ ready ── ░▒▓ ██ ▓▒░ ── $ recurse run ./agent ── ⚡ tools.search() ── │ ├── verify() │ └── return result ── > _ ready ── ░▒▓ ██ ▓▒░ ── $ recurse run ./agent ── ⚡ tools.search() ── │ ├── verify() │ └── return result ── > _ ready ── ░▒▓ ██ ▓▒░ ── $ recurse run ./agent ── ⚡ tools.search() ── │ ├── verify() │ └── return result ── > _ ready ── ░▒▓ ██ ▓▒░ ──

任务规划与修订：生成候选方案 07，进行测量，修订后等待评分。

构建并部署 Agent：固定 manifest，校验输入与输出，并部署为 MCP。

text ⟩ agent.build() ── █ manifest.pin ── ├── inputs.validate() ── │ outputs.check ── ░░▒▒▓▓██ ── $ recurse deploy --as mcp ── ⟩ agent.build() ── █ manifest.pin ── ├── inputs.validate() ── │ outputs.check ── ░░▒▒▓▓██ ── $ recurse deploy --as mcp ── ⟩ agent.build() ── █ manifest.pin ── ├── inputs.validate() ── │ outputs.check ── ░░▒▒▓▓██ ── $ recurse deploy --as mcp ── ⟩ agent.build() ── █ manifest.pin ── ├── inputs.validate() ── │ outputs.check ── ░░▒▒▓▓██ ── $ recurse deploy --as mcp ── ⟩ agent.build() ── █ manifest.pin ── ├── inputs.validate() ── │ outputs.check ── ░░▒▒▓▓██ ── $ recurse deploy --as mcp ── ⟩ agent.build() ── █ manifest.pin ── ├── inputs.validate() ── │ outputs.check ── ░░▒▒▓▓██ ── $ recurse deploy --as mcp ──

搜索样本评估：得分 0.91 的结果保留，得分 0.87 的结果丢弃；随后查询状态。

text ├── search.sample() ── ⚡ score 0.91 ── │ └── keep ── > score 0.87 · discard ── ▒▓██▓▒ ── $ recurse status ── ├── search.sample() ── ⚡ score 0.91 ── │ └── keep ── > score 0.87 · discard ── ▒▓██▓▒ ── $ recurse status ── ├── search.sample() ── ⚡ score 0.91 ── │ └── keep ── > score 0.87 · discard ── ▒▓██▓▒ ── $ recurse status ── ├── search.sample() ── ⚡ score 0.91 ── │ └── keep ── > score 0.87 · discard ── ▒▓██▓▒ ── $ recurse status ── ├── search.sample() ── ⚡ score 0.91 ── │ └── keep ── > score 0.87 · discard ── ▒▓██▓▒ ── $ recurse status ── ├── search.sample() ── ⚡ score 0.91 ── │ └── keep ── > score 0.87 · discard ── ▒▓██▓▒ ── $ recurse status ──

保持契约并注册工具：执行运行实例 run_9fd3c2，修订 prompt，随后 Agent 进入空闲状态。

text │ contract.hold ── ✓ tool.register ── ⟩ run_9fd3c2 ── ⚙ prompt.revise ── ░▒▓ ▓▒░ ── > agent.idle ── │ contract.hold ── ✓ tool.register ── ⟩ run_9fd3c2 ── ⚙ prompt.revise ── ░▒▓ ▓▒░ ── > agent.idle ── │ contract.hold ── ✓ tool.register ── ⟩ run_9fd3c2 ── ⚙ prompt.revise ── ░▒▓ ▓▒░ ── > agent.idle ── │ contract.hold ── ✓ tool.register ── ⟩ run_9fd3c2 ── ⚙ prompt.revise ── ░▒▓ ▓▒░ ── > agent.idle ── │ contract.hold ── ✓ tool.register ── ⟩ run_9fd3c2 ── ⚙ prompt.revise ── ░▒▓ ▓▒░ ── > agent.idle ── │ contract.hold ── ✓ tool.register ── ⟩ run_9fd3c2 ── ⚙ prompt.revise ── ░▒▓ ▓▒░ ── > agent.idle ──

候选方案 08：生成 1 个产物，执行测试校验并继续循环；随后将 Recurse 添加至 Codex MCP。

text ⟩ candidate 08 ── █ artifacts: 1 ── ├── test.validate ── │ loop.continue ── ██▓▒░░▒▓ ── $ codex mcp add recurse ── ⟩ candidate 08 ── █ artifacts: 1 ── ├── test.validate ── │ loop.continue ── ██▓▒░░▒▓ ── $ codex mcp add recurse ── ⟩ candidate 08 ── █ artifacts: 1 ── ├── test.validate ── │ loop.continue ── ██▓▒░░▒▓ ── $ codex mcp add recurse ── ⟩ candidate 08 ── █ artifacts: 1 ── ├── test.validate ── │ loop.continue ── ██▓▒░░▒▓ ── $ codex mcp add recurse ── ⟩ candidate 08 ── █ artifacts: 1 ── ├── test.validate ── │ loop.continue ── ██▓▒░░▒▓ ── $ codex mcp add recurse ── ⟩ candidate 08 ── █ artifacts: 1 ── ├── test.validate ── │ loop.continue ── ██▓▒░░▒▓ ── $ codex mcp add recurse ──

接入 Claude：添加 Recurse MCP，部署 mcp_7fc21a，端点就绪后开始提供专用 Agent 服务。

text $ claude mcp add recurse ── ⚡ deploy mcp_7fc21a ── │ ├── endpoint.ready │ └── specialist.serve ── > _ complete ── ░▒▓██▓▒░ ── $ claude mcp add recurse ── ⚡ deploy mcp_7fc21a ── │ ├── endpoint.ready │ └── specialist.serve ── > _ complete ── ░▒▓██▓▒░ ── $ claude mcp add recurse ── ⚡ deploy mcp_7fc21a ── │ ├── endpoint.ready │ └── specialist.serve ── > _ complete ── ░▒▓██▓▒░ ── $ claude mcp add recurse ── ⚡ deploy mcp_7fc21a ── │ ├── endpoint.ready │ └── specialist.serve ── > _ complete ── ░▒▓██▓▒░ ── $ claude mcp add recurse ── ⚡ deploy mcp_7fc21a ── │ ├── endpoint.ready │ └── specialist.serve ── > _ complete ── ░▒▓██▓▒░ ── $ claude mcp add recurse ── ⚡ deploy mcp_7fc21a ── │ ├── endpoint.ready │ └── specialist.serve ── > _ complete ── ░▒▓██▓▒░ ──

循环结束：维持稳定契约与自适应执行，跟踪测量结果并由 Agent 反思。
