Remote plugins graduate from experimental to stable, but the team is tightening agent spawning rules after a simplification removed critical delegation guidance.

Codex is shipping remote plugins enabled by default [1], moving the feature out of experimental and into production for all configurations that don't explicitly disable it. The backend authentication gate remains in place, so this is a controlled rollout, not a free-for-all. At the same time, the team restored v1 delegation guidance [2] that was accidentally stripped out earlier, re-establishing the rule that requests for depth, research, or investigation don't automatically authorize spawning subagents. This matters because the simplification that removed that guidance left the authorization check intact but lost the reasoning behind it, which engineers clearly found too permissive in practice. On the model side, Codex is now consuming model metadata to control skills usage instructions [3], removing hardcoded legacy matching and enabling the pattern for gpt-5.5. A revert [4] backed out an overly aggressive auto-review prompt change, and the team cut a routine patch [5] with no user-facing impact.

Action items

→ If you maintain Codex integrations, test remote plugins in staging before merging to main - they're now on by default openai/codex [plan]
→ Review your agent spawn implementations against the restored delegation guidance - depth/research requests should not trigger subagent creation openai/codex [plan]
