How it fires

How this skill gets triggered: by you, by Claude, or both.

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

LangGraph Subgraph Skill

Capabilities

  • Design modular subgraph components
  • Compose subgraphs into parent workflows
  • Handle state mapping between graphs
  • Implement subgraph reusability patterns
  • Design subgraph interfaces and contracts
  • Handle subgraph error isolation

Target Processes

  • multi-agent-system
  • langgraph-workflow-design

Implementation Details

Subgraph Patterns

1. **Compiled Subgraphs**: Pre-compiled reusable components 2. **State Mapping**: Input/output state transformation 3. **Nested Subgraphs**: Multi-level graph composition 4. **Parallel Subgraphs**: Concurrent subgraph execution

Configuration Options

  • State schema alignment
  • Input/output key mapping
  • Error propagation settings
  • Subgraph checkpoint inheritance
  • Timeout configurations

Best Practices

  • Clear subgraph interfaces
  • Minimal state coupling
  • Proper error boundaries
  • Reusable component design
  • Documentation for subgraph contracts

Dependencies

  • langgraph
