Web Artifacts Builder Codex

Overview

Use this skill to build standalone web artifacts that open cleanly, explain themselves through the interface, and ship with enough runtime and visual evidence for another reviewer to trust the result.

Design Upskill Contribution

This skill teaches Codex to treat web artifacts as deliverables, not just files. It improves no-template design by pairing layout and interaction choices with package evidence: screenshot captures, console capture, request failures, PDF export when useful, and a concise evidence bundle.

It matters because standalone artifacts often lack the guardrails of an existing app. The artifact must carry its own hierarchy, navigation, source notes, and failure evidence.
