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?

Environment

  • Claude Code for VS Code: 2.1.111
  • VS Code: 1.114.0 (Universal), macOS arm64 25.4.0
  • Model: claude-opus-4-7[1m]

Setting "showThinkingSummaries": true is set in ~/.claude/settings.json. The Opus 4.7 changelog states:

Changed thinking summaries to no longer be generated by default in interactive sessions — set showThinkingSummaries: true in settings.json to restore

After applying the setting and reloading the VS Code window, no thinking summaries appear anywhere in the extension UI on Opus 4.7. Switching the session model back to claude-opus-4-6 restores them immediately.

The schema description for showThinkingSummaries references a "transcript view (ctrl+o)", but ctrl+o is not bound in the VS Code extension and no equivalent command appears in the command palette.

What Should Happen?

With "showThinkingSummaries": true set, Opus 4.7 thinking summaries should be visible in the VS Code extension, matching the changelog's documented behavior and the experience on Opus 4.6.

Error Messages/Logs

Steps to Reproduce

  1. Add "showThinkingSummaries": true to ~/.claude/settings.json
  2. Set model to claude-opus-4-7 in the VS Code extension
  3. Reload the VS Code window (⌘⇧P → "Developer: Reload Window")
  4. Start a new Claude Code session and send any prompt that should trigger thinking (e.g. a non-trivial code question)
  5. Observe: no thinking summaries appear anywhere in the extension UI
  6. Switch the model to claude-opus-4-6 and repeat — summaries appear as expected

Is this a regression?

Yes, this worked in a previous version

Last Working Version

N/A — regression is tied to model, not extension version. Same 2.1.111 works on Opus 4.6.

extent analysis

TL;DR

The issue can be resolved by investigating the implementation of the showThinkingSummaries setting in the Opus 4.7 model and ensuring it is correctly integrated with the VS Code extension.

Guidance

  • Verify that the showThinkingSummaries setting is being correctly read from the ~/.claude/settings.json file in the Opus 4.7 model.
  • Check the Opus 4.7 model's documentation and code to see if there are any specific requirements or changes needed to enable thinking summaries.
  • Investigate why the ctrl+o shortcut is not bound in the VS Code extension and if there is an equivalent command in the command palette that can be used to view thinking summaries.
  • Test the showThinkingSummaries setting with different models, such as claude-opus-4-6, to see if the issue is specific to the Opus 4.7 model.

Example

No code snippet is provided as the issue is related to the integration of the showThinkingSummaries setting with the Opus 4.7 model and the VS Code extension.

Notes

The issue is a regression and was working in a previous version, specifically with the claude-opus-4-6 model. The Opus 4.7 model's changelog mentions that thinking summaries are no longer generated by default, but can be restored by setting showThinkingSummaries: true in the settings.json file.

Recommendation

Apply workaround: Investigate and resolve the integration issue between the showThinkingSummaries setting and the Opus 4.7 model, as the setting is not working as expected.
