Coding Agents

Agent skills that give coding agents design taste. They use art direction, reference images and a browser check to avoid generic AI-looking frontends. Install them with npx skills or as a Claude Code or Codex plugin.

Pros & cons

Each point cites its sources and says what kind of evidence backs it. A second reviewer tried to refute every claim before it was kept.

Pros

  • Docsv2 picks a researched art direction, builds with credited real photos, checks the page in a real browser at three widths and fixes the top issues from its own screenshots.[1]
  • DocsNeeds no API keys and installs nothing; it is namespaced as taste-skill: so it doesn't collide with other skills.[1]
  • DocsGrounded in a study of 247 curated sites, and a separate route handles dashboards and app screens.[1]
  • MetadataMIT, actively released (v2.1.5 on 2026-10-24), with only 5 open issues.[1]

Cons

  • DocsA build takes roughly 30 to 45 minutes and a few hundred thousand tokens.[1]
  • DocsRequires Node 22+, an installed Chrome, Edge or Chromium, and network access to find images.[1]
  • User reportsEarlier companion skills moved out, and users hit 'No matching skills found' on install and complained that agents don't reliably follow the rules.[1][2][3]
  • User reportsOne commenter says tasteskill.dev, the site its license points to, itself looks like slop.[1]
Best for
Agents producing landing pages or app screens that must not look like generic AI templates.
Watch out for
Token and time costs are high per page, so save it for work where design quality matters.
