bunfig.toml

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 dependency installer now refuses to run bun if a bunfig.toml file is found

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.275.

The earliest release whose published evidence quoted bunfig.toml was v2.1.275, 17 Sep 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
v2.1.27517 Sep 2026a bunfig.toml beside the bun lockfile can load code at install time (install.security scanner)
v2.1.28630 Sep 2026Skipped: a bunfig.toml beside the bun lockfile can load code at install time (install.security scanner); remove it, or ship a package-lock.json instead.

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.
