Automated README summary

Automatically summarized from the README on 1 Nov 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A Chrome MV3 extension that uses TypeSafe Jev to hide high-confidence sexual and solicitation content on X, covering both posts and replies, with a recoverable placeholder instead of silent removal.

How it uses Jev

For each post or reply, the content script sends text to the service worker, which calls Jev to get calibrated probabilities per rule. A local rule engine then decides whether to hide the item based on thresholds; hidden items show a placeholder that can be restored.

Primitives:score

Technique worth stealing

Use a judgment model with calibrated probabilities and local thresholding instead of keyword matching, with fail-open on API errors.

Try it

Download the latest ZIP from Releases, load the unpacked folder in chrome://extensions, and enter your TypeSafe API key.

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.
