A test case the skill fixed. Same model, same prompt, with and without the skill.

Prompt

An execution thread was interrupted prior to tool execution and is waiting for human intervention. After human approval, how is execution resumed on that specific thread?

langgraph-state-graph

Build stateful agent workflows using LangGraph's StateGraph pattern. Design state schemas, create nodes, define edges with conditional routing, and enable persistence.

Overview

LangGraph is a library for building stateful, multi-actor applications with LLMs. The StateGraph is the core abstraction that enables:

Cyclical computation graphs (unlike DAGs)
State persistence and checkpointing
Human-in-the-loop interaction patterns
Conditional branching and routing
Multi-agent coordination

Capabilities

State Schema Design

Define typed state schemas with TypedDict or Pydantic
Configure state channels for message passing
Set up reducer functions for state updates
Design accumulator patterns for conversation history

Graph Construction

Create nodes as functions or runnables
Define edges (normal, conditional, entry points)
Configure start and end nodes
Implement routing logic for conditional edges

Persistence & Checkpointing

Configure checkpoint backends (SQLite, PostgreSQL, Redis)
Enable state snapshots at each step
Support for resuming interrupted workflows
Thread-based conversation persistence

Human-in-the-Loop

Insert interrupt points in workflows
Collect human feedback before continuing
Support approval gates and input collection
Resume from interrupt with updated state
