LangGraph Patterns Expert SKILL.md skillA
LangGraph Patterns Expert from frankxai/agentic-creator-os is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add frankxai/agentic-creator-os/LangGraph Patterns Expert@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Build production-grade agentic workflows with LangGraph using graph-based orchestration, state machines, human-in-the-loop, and advanced control flow.
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
# LangGraph Patterns Expert Skill
## Purpose
Master LangGraph for building production-ready AI agents with fine-grained control, checkpointing, streaming, and complex state management.
## Core Philosophy
**LangGraph is:** An orchestration framework with both declarative and imperative APIs focused on control and durability for production agents.
**Not:** High-level abstractions that hide complexity - instead provides building blocks for full control.
**Migration:** LangGraph replaces legacy AgentExecutor - migrate all old code.
## The Six Production Features
1. **Parallelization** - Run multiple nodes concurrently
2. **Streaming** - Real-time partial outputs
3. **Checkpointing** - Pause/resume execution
4. **Human-in-the-Loop** - Approval/correction workflows
5. **Tracing** - Observability and debugging
6. **Task Queue** - Asynchronous job processing
## Graph-Based Architecture
```python
from langgraph.graph import StateGraph, END
# Define state
class AgentState(TypedDict):
messages: Annotated[list, add_messages]
next_action: str
# Create graph
graph = StateGraph(AgentState)
# Add nodes
graph.add_node("analyze", analyze_node)

How to install
mdr add frankxai/agentic-creator-os/LangGraph Patterns Expert@sha256:a24e4cb218968e30The line at the top of this page pins the label v1.0.0, 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.
