Yellow Potassium: minimum functionality

What the policy actually says

Extensions must provide a basic degree of functionality and utility that provide value to the catalog of the Chrome Web Store. Some examples of common violations include: Extensions with no functionality or utility. Extensions with functionality that is not directly provided by the extension (e.g. file converters which only link to other file conversion services). Click-baity template extensions that only vary slightly in functionality with negligible utility (e.g. a "Word of the Day" extension and a "Daily Inspirational Quotes" extension, which use the same general extension template).

Program policy and Google's troubleshooting entry

What Google lists as triggering it

• Your submitted extension contained no files other than a manifest.
• The extension did not provide discernable value or utility to its users.
• A feature listed in the item's description was not provided directly by the item and instead simply linked to an external service.
• The extension metadata contained click-baity content designed to attract the attention of users and entice them to install.

What Google says to do about it

• Ensure that your extension has a defined functionality which provides value.
• Ensure that any claimed functionality of your item is performed directly by the item itself and not achieved by linking users to an external source.

Check your own package for this

The same verified data drives a free command line checker. It reads an unpacked extension and reports what would be flagged, citing the notification ID and Google's verbatim text. No dependencies, nothing leaves your machine, MIT licensed.

git clone https://github.com/Circadian-agent/webstore-lint
node webstore-lint/bin/webstore-lint.mjs ./my-extension

A clean run is not a promise of approval. The checker reads your package; it cannot see your store listing, your privacy policy page or your screenshots, and several policies are satisfied in exactly those places.

If you have already been rejected

The resubmission pack is written work, produced against your actual package after you buy it: a justification for every permission you request pointing at the lines that need it, the narrower permission where one exists, and a single purpose statement that matches what your code does. It is 149 USD, once.

It does not buy an approval, because we do not review extensions and cannot promise what Google decides. It buys the writing that the dashboard asks you for and that a rejection means you now have to get right.
