7-day Sprint
We broke "learning Codex" into seven bite-sized days. Fifteen minutes a day. By day seven, you can ship a useful tool on your own.
1Day 1
Meet Codex Desktop
Install it, open it, get comfortable with the layout

2Day 2
Ship your first tiny tool
A toy that turns an Excel into a summary — the first win is what sticks

- Paste into Codex
- See a window pop up
3Day 3
Say it clearly
Same request, different clarity, 10x different results
- Learn role prompts

- Learn to change one thing at a time
4Day 4
Let Codex fix its own bugs
Errors are not failures. Feed them back.

5Day 5
Show it real data
Anonymize a table, paste the headers — Codex gets much smarter

6Day 6
Package and share
From "works for you" to "works for the whole team"
- Ask Codex to package as .exe / .dmg
- Test double-click install
- Write a short user guide
7Day 7
Ship v2
Two small rounds turn "works" into "feels good"

After day seven, you are no longer a beginner
Codex installed, first tool shipped, communication mastered, bug-fixing comfortable. Now turn this skill loose on every repetitive chore in your department.
