Codex Cloud launches configurable agent environments

The real upgrade is reproducibility: Codex Cloud is becoming agent infrastructure rather than a disposable remote coding session.

• –Reusable environments can standardize runtimes, setup scripts, tools, and repository access
• –Isolated task workspaces let multiple agents work in parallel while developers are offline
• –Configurable network access and secrets make cloud execution more practical for real projects
• –The shared Agents API harness could bring long-running sessions, tool use, and subagents to external applications
• –Teams still need to manage setup drift, permission boundaries, and cloud-versus-local debugging differences
