Chrome extension structure, Manifest V3, the popup, content scripts, service workers, and storage. Use when creating an extension, editing manifest.json, adding a permission, building the popup UI, injecting a content script, or wiring message passing. Triggers on manifest.json with manifest_version, chrome.tabs, chrome.scripting, chrome.storage, chrome.runtime.onMessage, service-worker.js, popup.html, and loading an unpacked extension.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chrome Extension
**Manifest V3, a popup styled in Catppuccin Mocha, and the minimum permissions the extension actually needs.**
Manifest V2 is removed from Chrome, so V3 is the only target. This assumes unpacked or sideloaded distribution; a Web Store listing adds review requirements and a signing key that change the packaging step.

How to install
mdr add tanq16/claudex/chrome-extension@sha256:283ad0ab5df3dd3bThe line at the top of this page pins the label git:20260823.82d58cc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
