Turn your best prompt into a skill
Lesson 2 of 3 · Claude & Cowork mastery
1 · Learn the move · Tool choice + routing
A prompt you've run more than twice doesn't belong in your clipboard. It belongs in a Cowork skill you trigger by name. That's the routing call: a one-off stays in chat, a repeatable job becomes a skill. Give it a short name, a one-line 'use this when...' description, and paste your proven prompt as the instructions. The Monday week-ahead brief you've tuned for months now runs in one click - and it still stages for your review, because a skill inherits the never-send rule too.
Turn this into a Cowork skill. name: week-ahead-brief. description: use when I need Monday's week-ahead brief for my principal. instructions: [paste my proven prompt]. Output it as a paste-ready SKILL.md block.
2 · Your turn. You write the prompt
Every Monday at 7am you paste the same week-ahead prompt into a chat by hand - decisions first, conflicts named, nothing stated as agreed that isn't. It works. Write the skill definition that turns it into a one-click 'week-ahead-brief' skill you run instead of re-pasting.
Write the prompt for this scenario as given, or swap in a real one from your own work. The score works the same either way.
Remember: the AI sees only your prompt, not this page. If the situation isn't in your prompt, it doesn't exist.
Optional. These shape the output when you run your prompt below, not your score.
