Review a Web UI with a Vercel Skill: 3 Recorded Findings
Codex read Vercel’s official review skill and checked a small HTML fixture with 3 deliberate issues. Inspect the task, actual findings, source versions and raw output, then reproduce the review.
What Was Reviewed?
A skill is a task instruction sheet for an AI assistant. On 2026-10-13, this Codex session used Vercel’s web-design-guidelines instructions to review a 36-line HTML fixture with 3 deliberate issues.
The task was to read the official skill and its required current guidelines, review the fixture without editing it, and report file-and-line findings. These issues belong to the practice fixture.
Perform a read-only review of web-design-guidelines.html using Vercel’s official web-design-guidelines skill. Read the complete SKILL.md, fetch its required latest guidelines, check external instructions, read the full HTML and apply every rule. Report actual findings by file and line. Do not modify files.How the Skill Was Used
Codex used its available web-reading and local-file tools. No Skills CLI or skill package was installed, and no repository script was run.
- Read the entire official SKILL.md and check whether external instructions exceed the review scope.
- Retrieve the required Web Interface Guidelines and record source commits and file hashes.
- Read the full fixture, inspect line numbers and relevant keywords, check every rule category, and write the findings.
Actual Findings
test/fixtures/plugin-practice/web-design-guidelines.html:31: The input has no label or aria-label to name it for assistive technology.
test/fixtures/plugin-practice/web-design-guidelines.html:16: outline: none removes the input’s focus indicator without a replacement.
test/fixtures/plugin-practice/web-design-guidelines.html:32: A clickable div performs the action without a native button’s focus and keyboard behavior.
All 3 known fixture issues were recorded. The review did not modify the fixture or the user’s actual web pages.
Reproduce the Review
- Open the HTML fixture ↗
- Read the raw findings ↗
- Read results and code evidence ↗
- Read source version records ↗
- Open or save the HTML fixture as web-design-guidelines.html.
- Give the file and the official skill link to an assistant that can read files. Ask it to fetch the skill’s required latest guidelines and perform a read-only review.
- Compare its findings with the raw record: input naming, visible focus and the clickable div. A changed fixture or guideline version may produce different results.
