LangGraph Starter

​
Summary

This starter shows the smallest useful graph-shaped agent example in the repo: plan, route, synthesize.

​
Status

starter

​
Why It Exists

Framework comparison pages are easier to extend when contributors can point to small repo-owned examples instead of only to external demos. This starter keeps the shape recognizable without turning the repo into a framework tutorial set.

​
Quick Start

This project is a starter. Read src/graph.py for the minimal graph state and node boundaries, then expand it into a fuller runnable example if needed. For a repo-level smoke check, run python3 scripts/verify_example_projects.py from the repository root.

​
Included Sample Files

  • src/graph.py: a minimal plan, route, synthesize state transition sketch
  • src/branching.py: a narrow example of how route choice and retry policy can be made explicit
  • src/run_summary.py: a tiny reporting surface for turning graph state into a readable execution summary

​
Constraints

  • No framework dependency is wired.
  • The graph is illustrative rather than executable.
  • Tool adapters and model calls are placeholders.

​
Next Steps

  • Add a real runtime dependency.
  • Add one tool node and one retry path.
