rad-chrome-extension

rad-chrome-extension is a plugin for Claude Code from RadOrigin-LLC/RAD-Claude-Skills. Its manifest loads nothing; the 9 skills, 1 agent it bundles cost 1,294 tokens per session together, scanned A, original, Apache-2.0.

A development standards package for Manifest V3 Chrome extensions built with WXT, React, and TypeScript. It includes guidance for extension structure, security, permissions, messaging, storage, testing, and Chrome Web Store requirements, plus two Python validators.

In plain words
What is it for?
Use it when building or reviewing a Chrome extension, auditing its manifest and source, checking content-script and service-worker design, minimizing permissions, or preparing a release for the Chrome Web Store.
Why use it?
It catches extension-specific problems that ordinary code review may miss, such as excessive permissions, unsafe content-security settings, remote code, outdated Manifest V2 APIs, and patterns that can lead to store rejection.

Security

Grade A, and why

rad-chrome-extension 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 9d 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.

  "description": "MV3 Chrome extension development standards (WXT, React, TypeScript) with two pure-stdlib Python validators that catch what LLM eyeballing misses. Skills cover architecture, MV3 security (CSP, remote code ban, content script isolation), permission minimization and CWS compliance, typed messaging, storage selection, service worker lifecycle, React UI patterns, testing, and Chrome Web Store troubleshooting.\n\nThe chrome-ext-reviewer agent runs two validators before LLM judgment: `audit-manifest.py` (manifest.json audit for MV3 compliance, permission overreach, weak CSP, web_accessible_resources scoping, MV2 leftovers, CWS-rejection causes; auto-discovers WXT `.output/` build manifests) and `scan-mv3-violations.py` (greps source for CSP-banned `eval` / `new Function` / `setTimeout('string')`, remote `<script src=\"http\">` and dynamic imports of remote URLs, MV2-only `chrome.tabs.executeScript` / `chrome.browserAction` / `chrome.extension.getBackgroundPage`, blocking webRequest listeners, optional DOM-risk `innerHTML` / `document.write`). Both emit findings with severity and specific fix recommendations. Pure stdlib Python 3.8+.",

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.
