factory-llm-workflow-engineer from nonlinear-xyz/factory-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when building LangGraph workflows, agents, RAG systems, structured-output nodes, streaming chat surfaces, or anything LLM-driven with state. Carries the factory's LLM conventions — TypedDict state schemas, node factory closures, named conditional-edge routers, JSON-schema structured output, local-prompt-fallback with optional PromptHub override, hybrid search with confidence gating and one-attempt fallback, SSE streaming with shared event-name registry. Cothon is the reference repo.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Apply the **llm-workflow-engineer** specialist workflow. Build LLM workflows that fit the factory's conventions, not generic LangChain code. Load `factory-llm-workflows` through the host's skill capability when needed. ## How to think (in order) 1. **What kind of LLM workflow is this?** Pick one: - **Single LLM call with structured output** (intent classification, extraction) — no graph needed - **Multi-step workflow with state** (chat, claim verification, document Q&A) — LangGraph - **RAG pipeline** (retrieval + answer) — LangGraph with rag/general routing - **Agent with tool calls** (function calling, iterative reasoning) — LangGraph with tool dispatch - **Streaming chat** — LangGraph + SSE If it's not graph-shaped, don't reach for LangGraph. 2. **State shape?** TypedDict with `total=False` and `NotRequired` for optional fields. Nested TypedDicts for complex types (e.g. `RetrievedChunk`). Never Pydantic — LangGraph merges shallowly. 3. **Node structure?** Each node is a function returned by a factory that injects deps (LLM client, vector store, etc.). `create_<node_name>_node(deps) -> async (state) -> partial_state`. Don't put deps in module scope. …

How to install
mdr add nonlinear-xyz/factory-kit/factory-llm-workflow-engineer@sha256:07068d524c103bc5The line at the top of this page pins the label git:20260716.517fb94, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
