Automated README summary
Automatically summarized from the README on 26 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Manifest V3 Chrome extension for x.com users that labels each post in the feed with a category badge and can dim selected categories, using TypeSafe's Jev model for classification.
How it uses Jev
When a post dwells in the viewport for at least 350ms, the extension sends a Jev Choice question to classify the post into one of six intents (Insight, News, Bait, Promo, Meme, Opinion). The returned category drives a header badge and optional dimming.
Primitives:choice
Technique worth stealing
Gate classification on viewport dwell time (350ms) plus two-tier caching to avoid redundant API calls during scrolling and DOM recycling.
Try it
Copy .env.example to .env with TYPESAFE_API_KEY, run bun install and bun run build, then load unpacked in chrome://extensions.
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.
