Skip isolated presentation edits (layout, CSS, colors, spacing, typography or static copy) when interaction and data handling stay unchanged. Use for browser Web implementation or debugging involving HTML/URL trust boundaries, login redirects, auth/secrets, async requests or lifecycle, form submissions/retries, or preserving user input. Duplicate submissions, stale search results and failed form recovery qualify even without a security-related request. Read-only lookup, explanation and analysis do not trigger this skill; static review uses it only when its workflow invokes it. Excludes mobile, desktop and cross-platform apps.
