Why include Codex in this resource set
Several students move between tools during the term, and Codex on macOS is part of that ecosystem. The Session 4 lesson applies directly here: whatever tool you choose, planning before execution is the main quality control mechanism.
Codex can be very productive when used with clear constraints, short execution loops, and explicit review gates.
How to use Codex without losing control
Treat Codex as a collaborator that drafts and iterates, not as a final-authoring engine. Ask for options first, commit to one plan, and execute in small steps that you can inspect quickly. Keep anchor instructions in version control so your project assumptions remain stable as you switch between environments.
For coursework, this avoids the common pattern where the code compiles but the empirical logic drifts away from the research question.
