defaultToNo

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.

SDK hosts are told when a permission prompt must default to no and not pre-select approve.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.242.

The earliest release whose published evidence quoted defaultToNo was v2.1.242, 24 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
v2.1.24224 Aug 2026"True when the ask must not be approvable by a single stray keystroke (PermissionAskDecision.defaultToNo): a terminal-style prompt opens on its decline option and takes no digit shortcut. Hosts rendering approve options should not pre-select approve when set."

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.
