What's Wrong?

The Explore tool (which runs parallel Search operations) consistently gets interrupted when searching patterns that return large result sets. The interruption happens silently with "Interrupted · What should Claude do instead?" - no actual error message.

This is different from issue #11331 (subagent interruption after manual ESC) - here the interruption happens automatically without any user input, specifically during Explore/Search operations.

Debug Log Error

2026-03-19T05:26:30.346Z [ERROR] TypeError: TypeError: A.with is not a function
2026-03-19T05:26:44.468Z [ERROR] TypeError: TypeError: A.with is not a function

This error appears in debug log during the interruptions.

Environment

• Claude Code: 2.1.79 (latest via npm)
• OS: Ubuntu Linux
• Auth: Claude Max subscription
• Model: Opus 4.6

Reproduction Steps

1. Open a large codebase (100+ Python files)
2. Run a broad search query:

   > найди все TODO и FIXME в проекте

or in English:

   > find all TODO and FIXME in the project

1. Claude triggers Explore tool with multiple parallel Search operations
2. After 30-60 seconds of "Sautéed/Crunched for Xs", get "Interrupted"

Example Session Log

● Explore(Поиск заглушек в проекте)
  ⎿  Search(pattern: "TODO|FIXME|HACK|XXX|TEMP", path: "/project")
     Search(pattern: "NotImplementedError|not implemented", path: "/project")
     +1 more tool use
  ⎿  Interrupted · What should Claude do instead?

● Read 10 files (ctrl+o to expand)
  ⎿  Interrupted · What should Claude do instead?

✻ Sautéed for 48s

Expected Behavior

• Search should complete and return results (possibly truncated if too large)
• Or: Search should fail gracefully with an error message explaining the limit
• Or: Search should stream results progressively

Actual Behavior

• Silent interruption with no explanation
• TypeError in debug log suggests internal JS error
• Session becomes unstable, subsequent tool calls may also get interrupted

Workarounds

1. Break queries into smaller scopes:

   > find TODO only in src/decision_maker/

1. Use bash instead of Explore:

   > grep -rn "TODO" src/ | head -50

1. Restart Claude Code between large search operations

Additional Context

• VS Code sidebar Claude chat works fine with same subscription (parallel usage)
• The issue is specific to CLI tool execution, not API connectivity
• Happens consistently on codebases with 50+ files matching the pattern
• Debug log path: ~/.claude/debug/<session-id>.txt

Related Issues

• #11331 - Similar "Interrupted" symptom but different trigger (subagents after ESC)
• #33949 - Root cause analysis of abort state issues

What Should Happen?

• Search should complete and return results (possibly truncated if too large)
• Or: Search should fail gracefully with an error message explaining the limit
• Or: Search should stream results progressively
