Use this when the subject is images — alt text, image descriptions, 'do our images have alt text' — across the whole site, from the scan already on record. For one page checked right now, including one no scan has covered, use check_page_alt_text. Alt-text problems found on a website's most recent scan: images with missing, filename-like, vague or inaccurate alt text, each with the element selector, the current value, why it was flagged, and a suggested replacement. Scoped to the current scan, not the whole history. Each finding also carries "markupHint": an <img> tag rebuilt from the stored image URL and alt value, so you have something greppable — the selector describes the rendered DOM and appears in no source file. It is a reconstruction, not the markup that was scanned, so treat the src path and the alt value as search strings rather than diffing it against your source. How the counts relate: "rawFindings" is every row on record for the scan, "distinctImages" is how many source images those rows collapse to once per-page repeats and cache-variant URLs of one asset are merged, and "returned" is how many of those are in this response — returned <= distinctImages <= rawFindings, and the work is one alt decision per distinct image. A finding's "affectedImages" is a different kind of number and the one you must not sum: it counts images on that page sharing the finding's template, and every finding sampled from one template repeats it, so three findings reading 7 are one group of seven. "templateGroup" says which findings share a group, and "imagesInAffectedTemplates" is that roll-up already done once per group — quote it as the image total rather than adding anything up. "suggestedAlt" is written from the image alone, by a pass that never saw the page around it: if the image is decorative, or an adjacent link or caption already names the destination, alt="" is the correct fix and not the description offered — validate_fix on image-alt confirms alt="" as resolved. Every suggestion carries that as "suggestionCaveat"; the judge_alt_text prompt is the long version. Read-only — it does not change any alt text.
