Running Multiple AI Coding Agents: Coordination Is Harder Than Generating Code
Time_Positive_9123 · reddit · 2026-11-13
Nick from ArcheForge shares a real incident: while Codex worked on a feature, it noticed repo files changing — another agent was editing overlapping backend code, tests, and configs. A backend test run still passed 102 tests, but passing tests didn't mean the competing changes were compatible; Codex halted and reported the conflict.
Key lessons:
- Separate AI conversations don't automatically give you separate dev environments
- The team already uses Git worktrees, separate branches, and structured handoff reports, but boundaries still need explicit management
- Coordinating AI workers matters as much as the code they generate
No complete resolution yet; he asks how others running Claude Code, Codex, etc. in parallel prevent concurrent edits.
