Turn your best prompt into a skill

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. Now the prompt you practiced runs in one click, forever.
Turn this into a Cowork skill. name: friday-update. description: use when I need my weekly market update for active clients. instructions: [paste my proven prompt]. Output it as a paste-ready SKILL.md block.
2 · Your turn. You write the prompt
Every Friday you paste the same market-update prompt into Claude by hand. It works. You've tuned it over weeks. Write the skill definition that turns it into a one-click 'friday-update' skill you run instead of re-pasting.
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.
