What it is
The self-hosted runner can now snapshot an operator's Claude config and seed it into every session, with a drain-marker mechanism
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.271.
Presence across releases
1Build by build
8One 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.
First cited
2The earliest release whose published evidence quoted SELF_HOSTED_RUNNER_DRAIN_MARKER_FILE was v2.1.271, 14 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 above.
Names beside it
Every environment variable in the inventory starting self_hosted_runner_drain, up to twelve of them.
SELF_HOSTED_RUNNER_DRAIN_GRACE_MSNo description from anybody. v2.1.224
SELF_HOSTED_RUNNER_DRAIN_WAIT_MSSelf-hosted runner adds git URL-rewriting flags and an Anthropic-managed git auth option, plus a documented drain-wait timeout v2.1.224
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.
