Automated README summary
Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A small async LangGraph workflow that sends a mocked email to TypeSafe's Jev model, receives a typed Choice (invoice or general), and routes to a demo handler. Handlers only set a destination in graph state; they do not send email or make payments.
How it uses Jev
Jev detects intent from the email state, returning a Choice between invoice and general. The graph routes to the matching handler based on this Choice. Confidence and label probabilities are exposed for inspection, but the demo always routes to one of the two handlers.
Primitives:choice
Technique worth stealing
Use typed Choice to route emails in a LangGraph workflow.
Try it
uv sync; set TYPESAFE_API_KEY; uv run python main.py
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
