Bug Description
Title: Model hangs during Chrome automation — no output, token usage keeps climbing, "court" text spam after interrupt
Environment:
- Model: Claude Opus 4.8 (1M context) — claude-opus-4-8[1m]
- Platform: Windows 11 Pro (win32), PowerShell
- Context: using claude-in-chrome MCP browser tools
Symptoms:
- While operating Chrome (browser automation), the model produced no visible output and appeared frozen/hung.
- Despite no output, token consumption kept increasing the whole time (so it was generating internally, not idle).
- After interrupting, the screen flooded with repeated meaningless text (repeating the word "court" / garbled repetition — runaway generation).
Impact: Wasted tokens, session appears dead, requires manual interrupt; on interrupt the output is garbage.
Expected: Either produce a tool call / visible progress, or fail cleanly — not silently spin while burning tokens and then dump repeated tokens on interrupt.
