Most Codex users are getting cooked by basic setup.
You're still manually picking models every session like it's 2022. Meanwhile the real edge is sitting in config.toml and 90% of you are ignoring it.
Here's what actually matters:
→ Lock your default model + reasoning effort. Stop wasting 30 seconds every time you open a new chat.
→ Build profiles for different modes. Fast dev, code review, deep architecture — each needs its own config. Switch instantly instead of re-prompting.
→ Project-level configs = auto-load your stack + constraints. No more explaining the same tech setup 47 times.
→ Hook up auto-run for tests, linting, security checks. Let Codex validate without you babysitting every output.
If you're not using config.toml you're basically fighting with one hand tied. Fix it.
