Automated README summary
Automatically summarized from the README on 11 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A LangGraph conditional edge that uses TypeSafe AI's Jev model for fast, schema-safe routing between specialized agents. For developers who want sub-500ms routing without replacing their existing LLM router.
How it uses Jev
Jev answers which route to take from the newest user message and route descriptions. If confident, it returns the route directly; if unsure, unavailable, or mid-conversation, your existing router runs. Used via @jev_first decorator or install_shortcut.
Primitives:choice
Technique worth stealing
Shadow mode: run Jev alongside your router, compare decisions, then go live once agreement is high.
Try it
pip install -e ".[dev]"; pytest; python examples/01_quickstart.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.
