A Claude Code environment variable, read out of the shipped bundle. It was in the build from v2.1.299 and was gone by v2.1.305.
Setting CLAUDE_CODE_SETTLE_TOUCHED_FILES can now turn on the check that skips unchanged files when Claude Code looks for edits

First cited
1The earliest release whose published evidence quoted CLAUDE_CODE_SETTLE_TOUCHED_FILES was v2.1.299, 14 Oct 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.
Presence across releases
2Build by build
10One row per release since the first build this name was read out of. Absent means the build was read and the name was not in it, never mined means no bundle for that release was ever archived, and a declared type or a default is only ever what that release's own bundle stated.
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 environment variable does. All environment variables.
