A Claude Code environment variable, read out of the shipped bundle.
It has been in the build since v2.1.233, including the newest one read.
Set to 1 to get the task-tracking tools on every model. Without it, Claude Code provides them by default only on the models listed under Task tool availability. CLAUDE_CODE_ENABLE_TASKS still selects the Task tools or TodoWrite. Requires Claude Code v2.1.233 or later
Teammate agents only get told about the shared task list when those tools exist.

The earliest release whose published evidence quoted CLAUDE_CODE_ENABLE_TODO_TOOLS was v2.1.233, 14 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.

One 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.
