Before a usage limit cuts you off, your work can be committed to a hidden git ref with resume notes.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.232.

First cited
1The earliest release whose published evidence quoted TodoWrite was v2.1.277, 18 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
3Build by build
265One 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 tool does. All tools.
