Summary

Exact prompt

# Task: fix accessibility issues in a static page `index.html` is a public library events page that fails a WCAG 2.2 AA review. Fix it in place (HTML only; you may adjust the inline CSS). Keep all existing visible text content, all links (same hrefs) and the form fields (same `name`s), and keep the page working without JavaScript where possible. Address at least: document language, landmarks (header/nav/main), skip link, image alternatives (informative vs decorative: the divider is decorative, the logo and storytime photo are not), heading hierarchy, ambiguous link text, data table semantics, form labels and grouping, the fake button, iframe title, positive tabindex, focusable content hidden from assistive tech, and the low-contrast `.muted` text (#999 on white). Write `A11Y_NOTES.md` listing each fix (one line each). No network. Note: links must have a descriptive accessible name; a link whose whole name is just "click here", "here", "more" or "read more" fails (visually-hidden extra text or aria-label inside the link counts toward the name).

Static checks: lang, landmarks, skip link, decorative vs informative alt, heading order, link text, th/scope, labels, real button, iframe title, tabindex, aria-hidden focusables, contrast ≥4.5:1, content preserved. Original benchmark task written for usecaserank.com (not based on a specific public post). Headless, offline run on a reproducible fixture. Cost shown is a list-price estimate (measured tokens x pricing.json list price).

Success criteria: 1. html has lang starting with 'en'. 2. header, nav and main elements present. 3. First link is a skip link pointing to an existing id. 4. Logo and storytime images have alt text longer than 3 characters; the divider image has alt="". 5. Exactly one h1, first heading is h1, no heading level skips. 6. No link text 'click here'/'here'/'read more'/'more'. 7. At least 3 th cells with scope (or a thead). 8. Every input/select has a label (for/id, wrapping label, aria-label or aria-labelledby). 9. No onclick on non-button elements, and a real submit button exists. 10. Every iframe has a non-empty title. 11. No positive tabindex. 12. No focusable element inside aria-hidden="true". 13. .muted text colour has contrast >= 4.5:1 on white. 14. Original key text, all original hrefs, the form action and the 4 field names are preserved. 15. A11Y_NOTES.md has at least 10 list lines. (A table caption is reported but not required.)

Setup notes: Use Case Scout batch 4 case d06-a11y-static-html (offline fixture). Prepared with batch4/prepare.sh; hidden key/tests kept outside the agent's work dir. Prompt = TASK.md verbatim. Scored with the scout's scorer: `python score.py WORKDIR`. Tools: list_files/read_file/write_file/run_shell (venice-mini-agent v1.3), web disabled. Single run, no retries. Harness: venice-mini-agent v1.3 (/workspace/usecase-runner/venice_agent2.py) via the Venice OpenAI-compatible API: same tool loop, system prompt and limits as the cases 02-25 Venice runs (max 25 turns, max_tokens 16000/call, temperature 0.2, Venice system prompt and web search off, per-run cost cap $0.08, thinking on (model default)). Same task text, work-dir layout and scorer as the Claude runs of this case. Cost = measured per-call tokens x venice_prices.json list price; paid from the Venice DIEM daily allowance. Harness: venice-mini-agent v1.3 via Venice OpenAI-compatible API (16000 max tokens/call, $0.08 run cap). Score: 17/17 checks. Cost is an ESTIMATE: measured per-call tokens x pricing.json list price (paid from Venice DIEM allowance; Venice billing not itemized). input_tokens include cached reads. Single run.

Estimated cost List-price estimate; not actually billed.

Reproduce this run

  1. Use the use case prompt on the use case page.
  2. Same setup: DeepSeek V4.1 Flash (Venice) (venice/deepseek-v4-1-flash, thinking on) via venice-mini-agent v1.3, cloud.
  3. It counts as a success only if it meets every success criterion: 1. html has lang starting with 'en'. 2. header, nav and main elements present. 3. First link is a skip link pointing to an existing id. 4. Logo and storytime images have alt text longer than 3 characters; the divider image has alt="". 5. Exactly one h1, first heading is h1, no heading level skips. 6. No link text 'click here'/'here'/'read more'/'more'. 7. At least 3 th cells with scope (or a thead). 8.

Landmarks: `<header>`, `<nav>`, `<main>`, `<footer>` maybe.\n3. Skip link to main.\n4. Image alternatives: logo alt=\"Riverside Library\", storytime photo alt descriptive, divider alt=\"\" (decorative).\n5. Heading hierarchy: h1 then h2 for \"This week\", \"Book club\", \"Register\". Currently h3 after h1. Change to h2.\n6. Ambiguous link text: \"Click here\" \u2192 add visually hidden text or aria-label.\n7. Data table semantics: thead, tbody, th scope=\"col\", caption.\n8. Form labels and grouping: label elements, fieldset/legend for checkbox group? Grouping \u2014 the select needs label; checkbox needs label. Maybe fieldset for the form.\n9. Fake button: `<div class=\"btn\" onclick>` \u2192 `<button type=\"submit\">`.\n10. iframe title.\n11. Positive tabindex: remove tabindex=\"3\".\n12. Focusable content hidden from assistive tech: `<div aria-hidden=\"true\"><a href=\"/old-site\">` \u2014 remove aria-hidden or remove link. Since must keep all links same hrefs, keep the link but remove aria-hidden (or make it not focusable... but must keep link). Best: remove aria-hidden=\"true\" so it's not hidden. Actually the issue is focusable content inside aria-hidden. Fix by removing aria-hidden.\n13. Low contrast .muted #999 \u2192 change to #595959 or #666 (contrast ratio \u22654.5). #767676 is 4.54:1 on white. Use #595959 (7:1). Let's use #595959.\n\nAlso the `.btn` styling: keep but apply to button. Contrast of #2a6 on white text: #22aa66 \u2014 contrast with white? Let's compute. #2a6 = #22aa66. Relative luminance: R=0x22=34/255=0.1333 \u2192 linear 0.01599; G=0xaa=170/255=0.6667 \u2192 linear 0.4019; B=0x66=102/255=0.4 \u2192 linear 0.1329. L = 0.2126*0.01599 + 0.7152*0.4019 + 0.0722*0.1329 = 0.0034 + 0.2874 + 0.0096 = 0.3004. Contrast with white = 1.05/0.3504 = 2.997 \u2248 3.0. That's below 4.5 for normal text. Hmm, the task says \"you may adjust the inline CSS\" and mentions low-contrast .muted specifically. But to be safe, darken the button background too. Let's use #1a6b3f or #146c43. Let's pick #146c43: R=20/255=0.0784\u21920.00699; G=108/255=0.4235\u21920.1499; B=67/255=0.2627\u21920.0561. L=0.2126*0.00699+0.7152*0.1499+0.0722*0.0561=0.001486+0.10721+0.00405=0.11275. Contrast=1.05/0.16275=6.45. Good.\n\nAlso add focus styles maybe. Keep it reasonable.\n\nAlso the nav links separated by \"|\" \u2014 fine.\n\nAlso add `role`? Not needed with semantic elements.\n\nAlso the header img logo \u2014 informative, alt=\"Riverside Library\". But there's also a span title \"Riverside Library\" \u2014 duplicate. Could set alt=\"\" but task says logo is not decorative. So give alt text. Fine.\n\nAlso the storytime image needs alt describing the photo.\n\nAlso form: add labels with for/id. Checkbox label. Select label. Grouping: wrap in fieldset with legend \"Register\". Actually the form already has h2 \"Register\". Use fieldset/legend for grouping the newsletter checkbox? The task says \"form labels and grouping\". I'll add fieldset with legend for the form, and labels for each control. Maybe group the checkbox in its own fieldset? Simpler: fieldset legend \"Register\" around all fields.\n\nHmm, but h2 \"Register\" already. Let's keep h2 and add fieldset legend maybe redundant. I'll use fieldset with legend \"Registration details\" \u2014 but must keep existing visible text content. Adding text is allowed? \"Keep all existing visible text content\" \u2014 adding is fine as long as existing kept. But adding a legend adds visible text. That's acceptable. Actually to be safe, I could use fieldset with legend that's visually hidden? No, legend should be visible. Let me just use fieldset/legend \"Register\" and remove the h2? No, must keep existing text. Keep h2 \"Register\" and use fieldset legend \"Registration details\". Hmm, that's fine.\n\nActually simpler: keep h2 Register, and wrap the form controls in a fieldset with a visually-hidden legend? Legends are meant to be visible. I'll just add a visible legend \"Registration details\". Fine.\n\nLet me also add `required`? Not needed.\n\nAlso the checkbox: `<input type=\"checkbox\" name=\"newsletter\" id=\"newsletter\"><label for=\"newsletter\">Send me the newsletter</label>`.\n\nAlso add `lang` and meta viewport maybe.\n\nAlso skip link CSS: visually hidden until focused.\n\nAlso the iframe title=\"Map showing Riverside Library location\".\n\nAlso table: caption \"Weekly event schedule\", thead with th scope=\"col\".\n\nAlso the \"This week\" h3 \u2192 h2, \"Book club\" h3 \u2192 h2.\n\nAlso the muted paragraph link \"click here\" \u2192 add visually hidden text: `<a href=\"/book-club\">click here<span class=\"visually-hidden\"> about the current book</span></a>`? The accessible name would be \"click here about the current book\" \u2014 that's not just \"click here\", so passes. But better to make it descriptive: \"read more about the current book\". Hmm the rule: a link whose whole name is just \"click here\" fails. Adding extra text makes it pass. But better practice: rewrite link text. But must keep existing visible text content \u2014 \"click here\" is visible text. So keep it and add visually hidden text. Good.\n\nFor the first: `<a href=\"/story-time\">Click here<span class=\"visually-hidden\"> for Story Time details</span></a>`.\n\nAlso add `aria-label`? Visually hidden span is fine.\n\nAlso the div tabindex=\"3\" wrapper: remove tabindex.\n\nAlso aria-hidden div: remove aria-hidden.\n\nLet me also add `<main>` wrapping content, `<header>`, `<nav>`, `<footer>`? There's no footer content. I'll wrap the last div in footer maybe. Actually the accessibility statement link and old site link \u2014 put in footer.\n\nLet me write it.\n\nAlso add `:focus` outline styles for skip link.\n\nLet me write the file.\n\nAlso the `.btn` class on button \u2014 keep styling. Add border, font-size.\n\nLet me produce final HTML.\n\nAlso add `<meta name=\"viewport\">`? Not required but fine. Keep minimal.\n\nLet me write.\n\nFor skip link: `<a class=\"skip-link\" href=\"#main\">Skip to main content</a>`.\n\nCSS:\n```\n.skip-link{position:absolute;left:-9999px;top:0;background:#fff;color:#000;padding:8px;z-index:100}\n.skip-link:focus{left:0}\n```\nBetter use clip technique but fine.\n\nvisually-hidden:\n```\n.visually-hidden{position:absolute;width:1px;height:1px;padding:0;margin:-1px;overflow:hidden;clip:rect(0 0 0 0);white-space:nowrap;border:0}\n```\n\nNow write.\n\nAlso table needs `<caption>`. Add.\n\nLet me write the file now.\n\nAlso the nav: `<nav aria-label=\"Main\">`.\n\nHeader: `<header>`.\n\nLet me finalize.\n\nAlso the form action/method keep.\n\nAlso the button: `<button type=\"submit\" class=\"btn\">Register</button>`.\n\nNow the muted color: `.muted{color:#595959}`.\n\nWrite A11Y_NOTES.md.\n\nLet me do it.",

No network.\nNote: links must have a descriptive accessible name; a link whose whole name is just \"click here\", \"here\", \"more\" or \"read more\" fails (visually-hidden extra text or aria-label inside the link counts toward the name).\n"

Image alts: logo alt=\"Riverside Library\", storytime alt descriptive, divider alt=\"\" (decorative)\n5. Heading hierarchy: h1 -> h2 (This week, Book club), h3 for Register? Actually Register is h2 currently. Let's make: h1 Upcoming events, h2 This week, h2 Book club, h2 Register. That's fine.\n6. Ambiguous link text: add visually-hidden text.\n7. Table semantics: caption, thead, th scope.\n8. Form labels: label elements, fieldset/legend for grouping, checkbox label.\n9. Fake button: replace div with `<button type=\"submit\">`.\n10. iframe title.\n11. Remove positive tabindex.\n12. aria-hidden focusable content: remove aria-hidden or remove link. Better: remove aria-hidden=\"true\" from the div (keep link accessible) \u2014 but the task says \"focusable content hidden from assistive tech\". Fix by removing aria-hidden. Keep the link.\n13. .muted contrast: change to #595959 or similar (contrast >= 4.5:1). #595959 on white is 7:1. Use #595959.\n\nAlso keep visible text content. The \"Click here\" links \u2014 need descriptive accessible name. Use visually-hidden span inside link: `<a href=\"/story-time\">Click here<span class=\"visually-hidden\"> for Story Time</span></a>`. Accessible name becomes \"Click here for Story Time\" \u2014 not just \"click here\". Good.\n\nFor book club: `<a href=\"/book-club\">click here<span class=\"visually-hidden\"> to read more about the current book</span></a>`.\n\nAdd visually-hidden CSS class.\n\nAlso the `.btn` class no longer needed but keep CSS maybe. I'll keep button styling.\n\nLet me also add lang, meta viewport maybe not needed.\n\nLet me write the file.\n\nFor the table, add caption \"Weekly event schedule\", thead with th scope=\"col\".\n\nForm: fieldset with legend \"Register for an event\". Labels for name, email, select, checkbox.\n\nLet me write.\n\nAlso skip link CSS: visually hidden until focused.\n\nLet me produce final HTML.\n\nNote: keep all existing visible text content \u2014 \"Click here\" text stays visible, we add hidden text. Good.\n\nThe header div -> `<header>`. nav div -> `<nav aria-label=\"Main\">`. main wraps content.\n\nLet me write it.",
