Summary

The creator mentions a Codex usage reset and quotes an update on Astra quality issues. The update says some skills written for earlier models were triggering too often or stopping the model from checking its work. The lesson: check your skills again when you move to a new model.

Key points

Codex usage limits were reset at midnight.
Skills written for earlier models may trigger too often on a new model.
Old skills can also stop the model from checking its own work.
After a model upgrade, review your skills and agent instructions.
