Automated README summary
Automatically summarized from the README on 28 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
JevIt is a Thunderbird add-on that sorts email using plain-language yes/no recipes answered by TypeSafe's Jev model. It tags, stars, marks read, marks junk, or moves mail when a recipe's answer passes its threshold. Unofficial.
How it uses Jev
Each email becomes one System One request with a JSON state (sender, recipients, subject, cleaned body, headers, link hosts, attachments, own address). Every recipe is a Noul with yes/no criteria and up to 20 learned examples in the same request. A recipe matches at its threshold; star, read, junk and move wait until Jev is at least 90% sure.
Primitives:noul
Technique worth stealing
Bundle all recipes as Noul questions in one System One request per email, and cache scores by SHA-256 so re-triaging is free.
Try it
Install from addons.thunderbird.net or load manifest.json as a temporary add-on; run node test.js for tests.
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.
