CLAUDE_CODE_VERIFY_PROMPT

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_CODE_VERIFY_PROMPT is a Claude Code environment variable: The verify flow was reworked; the standalone prompt override no longer maps to how verification runs. Removed between v2.1.143 and v2.1.212, so current releases ignore it. It is not in the official reference.

Status	Removed between v2.1.143 and v2.1.212
Added	Added between v2.1.118 and v2.1.123
Category	Other
Official docs	Not listed

How to set it

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

export CLAUDE_CODE_VERIFY_PROMPT=<value>
claude

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

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