Split frontend and backend work across Claude Code and Codex
A poster ran Claude Code and Codex in parallel for 15 days, with Claude Code on the frontend and another agent on the backend.
What they did
The poster split work between Claude Code on the frontend and Codex on the backend, then used Tutti for 15 days as a shared workspace so both agents could see the same live context, files, and task outputs. Instead of re-explaining work at every handoff, they forwarded task cards between agents, used @ references to pull prior Claude conversations into Codex, and occasionally borrowed a teammate’s agent with its MCP setup already configured.
How it went
They said the main win was lower coordination overhead: easier handoffs, a board showing in-progress/completed/failed/stopped tasks, and faster recovery from failures by checking the last execution step. The poster also said two weeks was too short to fully stress-test the setup, and agent borrowing was less useful for solo async work.
Worth knowing
Their clearest advice was to use card forwarding immediately and borrow the teammate agent with the best MCP configuration, since that full setup carries over.
