About Grist

Why this exists

Howdy! Grist is my side quest in the world of AI. Enjoy the growing collection of prompts, skills, rules and experiments for product design, from figuring out what it can really do.

Each drop comes with a short note on why I use it and a file you can paste straight into Claude, Cursor or a CLAUDE.md. A new one lands every Friday, eight to a season.

Tested means I've used it on real work. Trying means I'm still finding out. The ideas are mine, and Claude helps me format the files. Add .md to any address if you'd rather read plain markdown.

Rarities

Rarity is how deep a drop goes. Higher tiers take more setup and give you more.

  1. CommonOne idea you can use straight away, like a rule or a short prompt.
  2. UncommonNeeds a little setup. A prompt with blanks to fill, or a checklist with steps.
  3. RareGoes deeper. A full review checklist, a longer prompt or a simple skill.
  4. EpicA template you fill in, with a worked example. Usually a spec or a bigger skill.
  5. LegendaryA whole kit to install, with examples and a note on when not to use it.
  6. UltraSeveral skills and a reviewer agent chained into one workflow. It stops for your approval along the way, and comes with a sample run.
