My normal setup today is two or three Claude Code sessions working the same repository from separate git worktrees — one refactoring, one writing tests, one chasing a bug. It is a genuine productivity multiplier, with one recurring failure mode:</p> <blockquote> <p>Agent A is halfway through refactoring <code>src/auth</code>. Agent B decides the quickest fix for its bug also lives in <code>src/auth/token.go</code>. Neither knows about the other. The result is silent overwrites or an unmergeable diff — produced by two tools that were each doing their job correctly.</p>
