Automated README summary

Automatically summarized from the README on 27 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A local tool that captures a Meta advertiser's active ads from the Ad Library, classifies each creative with the Jev (TypeSafe) model, and shows in a browser dashboard which patterns appear among ads that stay live longest.

How it uses Jev

Jev classifies each creative across seven dimensions (format, hook, angle, offer, proof, objection, call to action) using the image and text via a native endpoint, in batches, with single-choice questions. Confidence and full probability distributions are stored as returned; confidence below 0.65, missing visual evidence, or text-only classification flags the item for review.

Primitives:choice

Technique worth stealing

Reserving a fixed input-token budget before each paid call, replacing it with API-reported usage, and halting scheduling on unreliable usage.

Try it

Run `scripts/lab.py serve`, open http://127.0.0.1:5194, enter a page ID, then capture and classify.

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.
