Error Message

Bash(npm --version) ⎿  Error: claude-opus-4-7 is temporarily unavailable, so auto mode cannot determine the safety of Bash right now. Wait briefly and then try this action again. If it keeps failing, continue with other tasks that don't require this action and come back to it later. Note: reading files, searching code, and other read-only operations do not require the classifier and can still be used.

Root Cause

I think this is either a dupe, or a near-dupe of #38537 , but wanted to call it out because it needs a new fix.

Code Example

Bash(npm --version)

Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

Auto-mode uses the wrong model by default, and now that Opus has been upgraded to 4-7, it is failing with this message:

Bash(npm --version)
  ⎿  Error: claude-opus-4-7 is temporarily unavailable, so auto mode cannot determine the safety of Bash right now. Wait briefly and then try this action again. If it keeps failing, continue with other tasks that don't require this action and come back to it later. Note: reading files, searching code, and other read-only operations do not require the classifier and can still be used.

(Note that if you run "Opus 4.7 (1M context)", the failure message is: claude-opus-4-7[1m] is temporarily unavailable

I think this is either a dupe, or a near-dupe of #38537 , but wanted to call it out because it needs a new fix.

Downgrading to Sonnet allows auto mode to work, as does "manually" downgrading to Opus 4.6 (even though it is not an option in the /model menu): /model claude-opus-4-6

What Should Happen?

Auto mode should continue to work, even if I am using the new default Opus 4.7.

Steps to Reproduce

Use auto-mode with the new Opus 4.7 model Ask Claude code to run any command, and observe failure.

TL;DR

Downgrade to Opus 4.6 or Sonnet to temporarily workaround the auto-mode failure with Opus 4.7.

Guidance

  • The error message suggests that claude-opus-4-7 is temporarily unavailable, which might be a transient issue or a compatibility problem with the latest version of Claude Code.
  • Try downgrading to Opus 4.6 using the /model claude-opus-4-6 command to see if auto-mode works as expected.
  • If downgrading is not feasible, consider using Sonnet as an alternative model until the issue with Opus 4.7 is resolved.
  • Verify that the issue is indeed related to the Opus 4.7 model by checking if other models, like Sonnet, work correctly in auto-mode.

Example

No code snippet is provided as the issue seems to be related to model compatibility rather than code.

Notes

The issue might be related to a regression introduced in version 2.1.111 of Claude Code, as it worked in the previous version 2.1.100.

Recommendation

Apply workaround: Downgrade to Opus 4.6 or use Sonnet until the compatibility issue with Opus 4.7 is resolved, as it allows auto-mode to function correctly.
