What's Wrong?

The spinnerVerbs setting with mode: "replace" does not work in the Claude Code VSCode extension. Whimsical spinner messages ("Clauding'", "Wibbling", etc.) continue to appear regardless of configuration. Settings placed in all three documented scopes (user, project, local) are ignored.

What Should Happen?

Only "Thinking" should appear as the spinner verb.

Error Messages/Logs

No errors. The setting is silently ignored.

Steps to Reproduce

1. Add to ~/.claude/settings.json:

{"spinnerVerbs":{"mode":"replace","verbs":["Thinking"]},"spinnerTipsEnabled":false,"prefersReducedMotion":true}

1. Restart VS Code
2. Use Claude Code - whimsical verbs still appear

Additional Information

Same settings also added to .claude/settings.json (project scope) and .claude/settings.local.json (local scope) with no effect. This was marked resolved in #4034 via spinnerVerbs added in v2.1.23, but it does not function in the VSCode extension. All prior issues (#4034, #6548, #10420) are closed.
