feat: add LangGraph integration helper (v0.2.6)#13
Merged
Conversation
Adds shekel.integrations.langgraph.budgeted_graph() — a convenience context manager wrapping shekel.budget() for LangGraph workflows. Existing OpenAI/Anthropic patches cover cost tracking automatically. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

- Add budgeted_graph() to api-reference.md with full signature and examples - Add shekel[langgraph] extra to installation.md (section, dep table, troubleshooting) - Fix install command in langgraph.md and langgraph_demo.py to use shekel[langgraph] Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

mypy 1.19.1 follows imports into _pytest/terminal.py which uses match syntax (Python 3.10+), causing a hard [syntax] error when python_version = "3.9". Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
mypy 1.19.1 traverses into _pytest/terminal.py (site-packages) which uses match syntax incompatible with python_version = "3.9". Adding exclude = ["/_pytest/"] prevents the path from being scanned. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
On Python 3.11, mypy 1.19.1 follows imports into _pytest/terminal.py which uses match syntax (Python 3.10+), causing a fatal [syntax] error. Python 3.12 can parse match natively so the issue only surfaces in CI. Using follow_imports="skip" prevents mypy from traversing into _pytest.* regardless of how the import is reached.

No new provider adapter needed — existing OpenAI/Anthropic patches automatically intercept all LLM calls inside LangGraph nodes.
