What is frontend-experts?

A plugin that groups coding assistants for React and TypeScript frontend work, along with Playwright browser testing. Playwright is a tool for checking a website by controlling a real browser.

Use it for React and TypeScript development, browser-based end-to-end tests, visual checks, and general frontend quality work.

It brings related frontend development and testing help into one package. This reduces the need to set up separate assistants for building interfaces and checking them end to end.

Security

Grade A, and why

frontend-experts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
