What's Wrong?

Web Search tool successfully returns search results and they are used correctly by Claude, but the UI status line incorrectly displays "Did 0 searches" instead of the actual count.

Example:

⏺ Web Search("Auto Tab Discard Chrome extension suspend tabs 2026")
  ⎿  Did 0 searches in 34s

The search actually returned multiple valid results which Claude used to answer the question. The search itself works correctly — only the UI counter display is wrong.

This is different from existing issues like #10141, #13546, #11369, #27831 where the search genuinely fails and returns no results. In this case, the search succeeds but the counter shows 0.

What Should Happen?

The status line should display the actual number of searches performed, e.g. Did 1 search in 34s.

Error Messages/Logs

No error messages. The tool works correctly, only the display counter is wrong.

Steps to Reproduce

1. Use Claude Code on macOS with Anthropic API
2. Ask Claude to search for something via Web Search
3. Observe the status line shows "Did 0 searches in Xs" even though results are returned
