What its author says it does

Copied from the file, not written here

AI agent and LLM system engineering reference covering single-agent dev (ReAct, tool calling, plan-execute), multi-agent coordination (swarm, role decomposition, file locking), LLM security (prompt injection, jailbreak defense, output filtering), RAG architecture (chunking, hybrid retrieval, rerank), and prompt engineering / evaluation (RAGAS, LLM-as-Judge). Use when building AI agents, designing RAG pipelines, orchestrating multi-agent workflows, hardening LLM apps, or writing prompts.

丹鼎秘典 · Agent / LLM 工程

判断先于执行:决定「是否做 / 选什么 / 如何取舍」(栈、方案、架构、权衡)前,先读领域判断内核 skills/_kernel/ml/SKILL.md——它管 judgment,本秘典管 execution;冲突时以内核判断为准。

单 Agent 是器,多 Agent 是阵。先选规模,再选模式。

路由

意图加载核心
单 Agent 开发(工具调用、ReAct)agent-devReAct / Plan-Execute / Reflection
多 Agent 协同(>=3 文件 or >=2 并行)multi-agent-coordination蚁群仿生、文件锁、依赖图
多 Agent 协议细节(消息素、收阵报告)multi-agent-protocolCodex 原生协议、角色定义
LLM 安全(注入、越狱、输出过滤)llm-securityOWASP LLM Top 10 视角
RAG 系统(向量、检索、重排)rag-systemChunking / 混合检索 / Cohere rerank

规模决策

单步任务(一文件、一查询)         → 直接执行(不需要 Agent 框架)
多步任务(计划 + 工具)             → 单 Agent (ReAct)
复杂任务(>5 步、需反思)           → 单 Agent (Plan-Execute / Reflection)
独立并行任务(>=3 文件、>=2 流)    → 多 Agent (TeamCreate)
跨域协作(角色明确)                → 多 Agent (角色分工)

犹豫时优先 TeamCreate — 串行降级容易,并行升级难。

通用原则

Prompt 即代码须版控 | 输入输出皆验证 | 成本效果平衡 | 持续评估迭代 | 安全边界明确

跨场景铁律

  1. Prompt 版控 — Prompt 是代码,必须 Git;变更要走 review
  2. I/O 验证 — 输入侧防注入,输出侧防 hallucination 落地(结构化 schema、引用追溯)
  3. 评估前置 — 上线前必有 eval set;RAGAS / LLM-as-Judge 至少二选一
  4. 成本观测 — token / latency / 失败率必埋点;预算阈值自动告警
  5. 降级路径 — 多 Agent 失败 → 单 Agent;单 Agent 失败 → 直接回答 + 标记 [unverified]

多 Agent 启用判据

单一探索任务❌(用 explorer 或单 Agent)
单文件改动❌(用 worker 或直接执行)
单步任务❌(直接执行)
