CLAUDE_RUNNER_DISABLE_RENEWAL_WARNING

Updated November 6, 2026 by Alex Sorokoletov

CLAUDE_RUNNER_DISABLE_RENEWAL_WARNING is a Claude Code environment variable: When set, skips creating the session renewal warning poster; by default that poster is set up to warn about renewal. Added in v2.1.319 and still present in v2.1.319. 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_RUNNER_DISABLE_RENEWAL_WARNING=<value>
claude

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

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

• CLAUDE_RUNNER_DISABLE_TURN_BEGAN_BEFORE_INIT: Set to disable detecting that a turn began before the child initialized; turn-start signals are then ignored and the startup timeout does not switch to counting from the last activity line.
• CLAUDE_CODE_DISABLE_ADMIN_ENV_UNION: When set to true, uses only the leading admin tier's environment settings instead of merging (unioning) the environment across all admin tiers.
• CLAUDE_CODE_DISABLE_ARTIFACT
• CLAUDE_CODE_DISABLE_ATTACHMENTS: File/image attachments.
• CLAUDE_CODE_DISABLE_AWAITING_USER_IDLE: When set, stops the session from being treated as idle while it waits for user input, so time parked on the user is not counted as idle.
• CLAUDE_CODE_DISABLE_CFC_PROMPT
• CLAUDE_CODE_DISABLE_COMMAND_INJECTION_CHECK: Previously allowed disabling command injection detection.
