Each prompt declares its variables, the model that fits best, the expected output shape, and why it was written. Click any card to expand and copy.

How to use these

  1. Pick a model that fits. The "best model" tag on each prompt is a starting point — Opus for prompts that require deep multi-pass reasoning (audits, strategy), Sonnet for the rest.
  2. Replace every variable. If you leave {{double_braces}} in the prompt, the model will produce generic output. Each variable has an example to anchor the format.
  3. Read the expected output shape. If what you get back is structurally different from the shape described, the model went off-track — re-prompt rather than accept the drift.
  4. Iterate. These are starting points, not magic incantations. Edit the prompt to your account's specific context — vertical, voice, constraints.
