CLAUDE_CODE_ARTIFACT_VERIFY

Updated October 14, 2026 by Alex Sorokoletov

CLAUDE_CODE_ARTIFACT_VERIFY is a Claude Code environment variable. Added in v2.1.238 and still present in v2.1.295. It is not in the official reference.

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_CODE_ARTIFACT_VERIFY=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_CODE_ARTIFACT_VERIFY": "<value>"
  }
}

• CLAUDE_CODE_ARTIFACT_DELETE: Enables the delete-Artifact path (owner-only, requires confirmation, blocked in plan mode).

• CLAUDE_CODE_ARTIFACT_VERSIONS: When set, the session can list and read an artifact's earlier versions; without it, a session reports that an artifact's earlier versions are not available.
• CLAUDE_CODE_VERIFY_PROMPT: The verify flow was reworked; the standalone prompt override no longer maps to how verification runs.
