What it is
New SELF_HOSTED_RUNNER_HOST_CONFIG_SNAPSHOT env var configures self-hosted runner config storage
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
1The earliest release whose published evidence quoted SELF_HOSTED_RUNNER_HOST_CONFIG_SNAPSHOT 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_host_config, up to twelve of them.
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.
