CLAUDE_CODE_ARTIFACT_TYPES
A Claude Code environment variable, read out of the shipped bundle. It has been in the build since v2.1.236, including the newest one read.
What it is
You could start a private artifact from a published template, but two server switches keep it shut here.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.236.
Presence across releases
| Releases | Reading | Declared type | Default |
|---|---|---|---|
| 2.1.245 – 2.1.250 5 releases | never mined | — | — |
| 2.1.236 – 2.1.243 8 releases | in the build | triBool | — |
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.

Names beside it
Every environment variable in the inventory starting claude_code_artifact, up to twelve of them.
CLAUDE_CODE_ARTIFACTPR review artifact pages can show a pinned button that approves the pull request from your GitHub account. 2.1.166
CLAUDE_CODE_ARTIFACT_ASSET_BASE_URLThree artifact environment variables are now recognised, with the API token stripped from spawned processes as a secret. 2.1.221

CLAUDE_CODE_ARTIFACT_AUTO_OPENSet to 0 to stop Claude Code from opening the browser automatically when a new [artifact](/docs/en/artifacts) is published. Republishing an existing artifact does not open the browser regardless of this setting 2.1.172
CLAUDE_CODE_ARTIFACT_COMMENT_FAST_ACKClaude can post a quick 'on it' note in artifact comment threads before the real reply, off unless enabled. 2.1.232
CLAUDE_CODE_ARTIFACT_COMMENT_FAST_ACK_FIXEDA cheaper canned way to acknowledge artifact comments exists but needs two env vars switched on. 2.1.235

CLAUDE_CODE_ARTIFACT_COMMENTSSet to 0 to stop Claude reading and replying to [comments on an artifact](/docs/en/artifacts#collect-comments-on-an-artifact). Has no effect when CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC has [turned artifacts off](/docs/en/artifacts#availability). Requires Claude Code v2.1.221 or later 2.1.221
CLAUDE_CODE_ARTIFACT_COMMENTS_AUTOREACTSet to 0 to stop Claude [replying on its own to comments sent to it](/docs/en/artifacts#let-claude-reply-to-comments-on-its-own). Requires Claude Code v2.1.228 or later 2.1.221
CLAUDE_CODE_ARTIFACT_DBPublished artifacts can gain a document database Claude reads and writes, off unless you set the env var. 2.1.224
CLAUDE_CODE_ARTIFACT_DELETEClaude can now read back a published artifact's contents; browsing, multi-file publishing and deletion are built but off. 2.1.239

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.
