parse-flyer-fortinos

Scraping grocery flyer deals into structured JSON requires iterating through paginated product cards using data-testid DOM selectors. This Skill automates that extraction process for Fortinos flyers, capturing prices, units, and deal conditions into normalized records.

Extracting paginated product data via Chrome DevTools Protocol requires a headed Chrome session listening on port 9222. This Skill uses CDP support to navigate `?page=N` URLs, parsing `.chakra-linkbox` product cards until titles are absent and returning a JSON array.

Handling DOM selector drift involves running a drift-detection diagnostic to check selector hit rates before paginating. This Skill includes stability guardrails that prevent wasting time on extraction when the target website's layout changes and selectors become unreliable.

Normalizing scraped grocery prices involves parsing sale prices, regular prices, and size units into structured fields. This Skill classifies products into categories and captures specific deal conditions like SAVE amounts, PC Optimum Points, and plus tax annotations.

A headed browser session is required to parse JavaScript-rendered flyer pages because the content relies on dynamic DOM loading. This Skill specifically requires a headed Chrome session with CDP support on port 9222 to properly execute and extract the flyer product tiles.
