From my point of view, update posts like this work best when they also call out one or two operational edge cases introduced by the new surface area. Features like hooks, dynamic variables, and MCP toggling are powerful, but they also change how people reason about control and safety in the loop. A compact section on migration notes or known rough edges would make weekly posts like this much more actionable for power users.
