CLAUDE_CODE_DISABLE_DANGEROUS_RM_TIMEOUT
A Claude Code environment variable, read out of the shipped bundle. It has been in the build since v2.1.281, including the newest one read.
Set to 1 to turn off the time limit on critical-path removal prompts. In auto mode Claude Code then sends these removals to the classifier instead, and in bypassPermissions mode the prompt waits for your answer. Set it in the environment that launches Claude Code, since Claude Code ignores a copy delivered through a settings env block. Requires Claude Code v2.1.281 or later

First cited
1The earliest release whose published evidence quoted CLAUDE_CODE_DISABLE_DANGEROUS_RM_TIMEOUT was v2.1.281, 23 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.
Presence across releases
1Build by build
3One 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.
