Problem Statement

Your fix in response to issue 6814 was helpful. It does not solve my issue.

I use Claude Code extensively in my work developing Julia packages and in IEEE standards development. Claude Code has become a valued part of my workflow.

The "processing" spinner (the blinking star, and the rapidly cycling word) is a substantive and unavoidable cognitive problem. The animation continually reasserts itself, pulling my focus, creating genuine distraction and obstructing my attention. I have to stop using Claude Code to elaborate design flow, review functions, or edit documentation.

The disutility of rapid peripheral motion for productivity is settled science, it is the basis for Web Accessibility Guideline 2.2.2.

Proposed Solution

provide a json configuration entry that sets the time elapsed between updates of the progress animation

Alternative Solutions

There is no workaround that keeps me with Claude Code in VS Code.

Priority

Critical - Blocking my work

Feature Category

Interactive mode (TUI)

Use Case Example

Everything I had been doing with Claude Code alongside becomes more difficult, I have to stop more frequently.
