setting never mined JSON

A Claude Code settings key, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

Plugin validation warns when marketplace or plugin names would be rejected by Claude Desktop's managed sync.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.221.

The earliest release whose published evidence quoted allowedPluginMarketplaces was v2.1.221, 3 Aug 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.

ReleaseDateThe span that was quoted
v2.1.2213 Aug 2026is reserved in Claude Desktop. Claude Code accepts it, but the Claude Desktop managed marketplace sync (allowedPluginMarketplaces) will reject the whole marketplace.

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the settings key does. All settings keys.
