图工程编排模式

核心思想(来自 deer-workflow /字节跳动 DeerFlow 3.0)

Code is the plan. Agents do the work.

  • TypeScript 定义合法执行路径(确定性控制流)
  • Agent 只负责每个节点的语义推理(可替换的运行时)
  • 分开"怎么走"和"走什么" —— 编排层和推理层解耦

为什么不用 LangChain/LangGraph

LangChain 的问题:框架太重,黑盒太多,Prompt 和编排混在一起,调试困难。

deer-workflow 的答案:

  • 编排 = 普通代码(可审查、可测试、可版本控制)
  • Agent = 可替换的运行时(今天 Codex,明天 Claude Code,后天 Hermes)
  • 输出 = JSONL 事件流(生产和调试都能用)

Hermes 应用模式

模式 1:DAG 任务拆解

用户任务 → Hermes 拆解成 DAG 节点 → 每个节点委派给 Agent → 汇总
# 确定性编排(代码写死路径)
tasks = [
    {"goal": "研究 X 方案", "context": "..."},
    {"goal": "研究 Y 方案", "context": "..."},
]
results = delegate_task(tasks=tasks)  # 并行执行

# 确定性汇总(代码做决策)
if results[0]["feasible"]:
    path = "X"

模式 2:Phase-aware 进度

借鉴 deer-workflow 的分阶段进度:

  • 每个阶段完成有明确状态标记
  • 终端实时显示进度
  • 失败节点可以单独重试

Hermes 中通过 todo 实现阶段管理。

模式 3:JSONL 事件流

所有 Agent 操作输出 JSONL,方便后续分析:

{"phase":"planning","status":"start"}
{"phase":"execution","node":"kicad_track","status":"done","duration_ms":2300}
{"phase":"verification","status":"fail","reason":"DRC违规"}

与 MCP 网关的结合

MCP 网关的 4 个 meta-tool 已经是图工程的前半段:

  • gateway_list_servers → 能力发现
  • gateway_list_tools → 节点定义
  • gateway_invoke → 节点执行

差的是后半段:编排引擎。可以用这个模式补上。

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
