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

LLM workflow conventions distilled from production agent/RAG work. Covers LangGraph TypedDict state schemas, node factory closures, conditional edge routing, structured output via JSON schema, prompt fallback patterns with optional PromptHub override, hybrid search with confidence gating + fallback supplement, SSE streaming with event dispatch, hexagonal ports/adapters when scale justifies. Read when building any LLM-driven workflow with state, tool calls, or streaming UX.
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
# Factory LLM workflows
Each section leads with **Principle** (one sentence, stack-agnostic), then **Why** (constraint → option → tradeoff), then **Recipe** (the LangGraph / FastAPI / SSE shape we use), and **Failure mode** when there's one to name. Sections that are pure style with no deeper truth are marked `Recipe only`.
## State shape — TypedDict, not Pydantic
**Principle.** LangGraph state is a TypedDict, not Pydantic. The state library's merge semantics dictate the shape.
**Why.** LangGraph merges state between nodes by shallow dict update — the framework expects a dict-like object whose fields are independently updatable. Pydantic validates on construction; every partial update fails validation or requires `.model_copy(update=...)`, which loses the simplicity. TypedDict matches the framework's semantics: it's a dict, fields are optional via `total=False`, the type annotations are documentation that the type checker enforces at call sites.
**Recipe.**
```py
from typing import TypedDict
from typing_extensions import NotRequired
class ChatState(TypedDict, total=False):
"""Documented fields. total=False makes everything optional."""

How to install
mdr add nonlinear-xyz/factory-kit/factory-llm-workflows@sha256:5da9ae65489d660dThe 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.
