CLAUDE_CODE_ARTIFACT_DIRECT_UPLOAD
A Claude Code environment variable, read out of the shipped bundle. It was in the build from v2.1.172 and was gone by v2.1.239.
What it is
Artifact availability now hinges on one gate, and direct upload kicks in for create paths.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.232.
Presence across releases
| Releases | Reading | Declared type | Default |
|---|---|---|---|
| 2.1.245 – 2.1.250 5 releases | never mined | — | — |
| 2.1.239 – 2.1.243 5 releases | not in the build | — | — |
| 2.1.172 – 2.1.238 60 releases | in the build | bool | — |
A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. 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.
