react-browser-verification

react-browser-verification is a skill for Claude Code, Codex from codysumpter-cloud/buddy-universal-agent-profile. It costs 30 tokens per session (197 once invoked), scanned A, original, Apache-2.0.

A review guide for React interface changes that uses a real browser to check behavior, accessibility, responsive layouts, and console or network errors.

In plain words
What is it for?
Use it to verify changed React routes, component behavior, focus and keyboard handling, loading and error states, responsive layouts, browser console output, and failed requests.
Why use it?
A passing build or screenshot may miss broken interactions, keyboard problems, loading states, or failures at different screen sizes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

react-browser-verification 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 3d 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 it actually says

React browser verification

Verify React changes in a real browser

Inspect component boundaries, state transitions, semantic HTML, keyboard behavior, focus handling, loading and error states, and responsive layout. Run repository-native tests and build checks, then exercise the changed route in a browser at representative viewport sizes. Check the browser console and failed network requests. Do not accept a snapshot or successful build as proof that the interaction works. Record the route, viewport, interaction, and observable result used as evidence.

Changes

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.
