Know your core.
Every team has a handful of skills it can't afford to lose, tools or no tools. Name them, practise them, and spread them.
Name them
Step 1
- List 5–8 skills the team must own
- e.g. debugging, SQL, reading code
Practise them
Step 2
- Regular reps, not occasional heroics
- See Day 27: AI-free reps
Spread them
Step 3
- No skill held by one person
- Pair across experience levels
Check them
Step 4
- Self-rate confidence each quarter
- Watch for skills trending down
Name the skills you must keep. Then practise them.
