Claude Code hooks prevent Chrome tab interference between multiple sessions
Problem and solution for multi-session Claude Code users
When using Claude-in-Chrome with multiple Claude Code sessions, sessions often forget which tab belongs to them, creating confusion where sessions accidentally get views of other sessions' tabs. This slows down and disrupts test runs, form fills, and other browser automation tasks.
Technical implementation
The fix consists of three hooks:
session-startcapture-tab-idenforce-tab-id
These hooks pin each session to its own tab. The PreToolUse hook rewrites the tabId on every browser call, enforcing tab isolation programmatically rather than through CLAUDE.md or Skills-based instructions that can degrade after context compaction.
Installation and availability
The solution is available as a drop-in installation for either project-specific or global use at: github.com/neonwatty/claude-in-chrome-multiplexing
The developer notes this is likely only a short-term problem, anticipating an official fix in the near future, but provides a functional workaround for current users experiencing this issue.
