# Parallel Isolated Workspaces Recommended mode: `repro-fix` Recommended startup: ```bash pyro host connect codex --mode repro-fix ``` Smoke target: ```bash make smoke-parallel-workspaces ``` Use this flow when the agent needs one isolated workspace per issue, branch, or review thread and must rediscover the right one later. Chat-host recipe: 1. Create one workspace per issue or branch with a human-friendly name and labels. 2. Mutate each workspace independently. 3. Rediscover the right workspace later with `workspace_list`. 4. Update metadata when ownership or issue mapping changes. 5. Delete each workspace independently when its task is done. The important proof here is operational, not syntactic: names, labels, list ordering, and file contents stay isolated even when multiple workspaces are active at the same time. Parallel work still means “open another workspace in the same mode,” not “pick a special parallel-work mode.”
