Fine to try.

Use when an SPA or SSR app flashes the wrong UI before client-side data resolves — an app-shell skeleton shown to visitors who get bounced to login, a results skeleton before "no results found", a light-theme flash before dark mode, a generic placeholder that swaps to something jarringly different. Covers resolving state at the edge/server, optimistic hint cookies, redirect-back (returnTo) flows, and how to test the loading window.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'no-ui-flash' ] || [ -L ~/.agents/skills/'no-ui-flash' ]; then echo 'A skill folder named no-ui-flash already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/vvedantb/eva' "$d" && git -C "$d" checkout --quiet '1bd8b90ceb62d31e79342108c8ddb0a6e4955287' -- '.agents/skills/no-ui-flash' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/no-ui-flash' ~/.agents/skills/'no-ui-flash' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'no-ui-flash' ~/.claude/skills/'no-ui-flash' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
