Getting started
Compatibility
Supported LangGraph version pairs for langgraph-hierarchies.
Regression tests gate version bumps. A compatibility pair is listed here only once the full test suite is green for it.
Matrix
| langgraph-hierarchies | langgraph |
|---|---|
| 0.0.x | 1.2.6 (pinned; see releases) |
The constraint in pyproject.toml is langgraph>=1.2.6,<2.0.0.
CI
The library CI runs ruff and pytest on every push/PR (Python 3.10–3.13). Tests use scripted models only — no LLM API keys required.
