Automated README summary
Automatically summarized from the README on 17 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A public zero-shot text classifier: send plain text and labels, get a label and calibrated confidence back. No API key or signup. Ships as one Cloudflare Worker, an npm CLI, and an MCP server.
How it uses Jev
Jev answers the classification decisions: state is an array of {id, text}, and each input gets its own typed question over the candidate labels. jev.ts packs inputs into batched requests and reads the returned probabilities; labels at or above 0.7 are returned, and low-confidence single-label answers are re-asked of a reasoning model.
Primitives:choicescore
Technique worth stealing
Batch many inputs into one Jev call by giving each item its own question, so a thousand texts cost one upstream request.

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.
