Automated README summary
Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Chrome and Firefox extension that scores draft X posts and reply context before posting, rendering a scorecard with virality, funniness, informativeness, clarity, insult level, ragebait, cringe, "sounds AI-written", regret risk, typo detection, and likely crowd reaction, plus an overall verdict.
How it uses Jev
Jev evaluates the draft text (and reply_to/quoting context) against rubrics in one request, returning scores for each metric. The content script normalizes scores to 0–1 and combines them into a verdict. Optional media descriptions from OpenAI are passed as media.
Primitives:scorenoulchoice
Technique worth stealing
Send all rubric questions to Jev in one request so adding rubrics costs tokens but not latency.
Try it
Load unpacked in Chrome or temporary add-on in Firefox, configure TypeSafe API key, then type on x.com/compose/post.
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.
