Automated README summary
Automatically summarized from the README on 25 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Hunch lets Ruby and Rails developers ask plain-English questions about text or application data and branch on the answers, turning judgment calls into ordinary Ruby control flow.
How it uses Jev
Hunch sends a state plus typed questions to a System One model such as Jev, which returns calibrated probabilities. Ruby code uses those probabilities for booleans, option picks, and ratings.
Primitives:choicescorenoul
Technique worth stealing
Use calibrated probabilities as ordinary Ruby control flow via named thresholds and typed questions.
Try it
gem "hunch"; configure Hunch::Backends::SystemOne with a System One endpoint.
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.
