How to Write AI Prompts That Actually Work: The R-C-F-C Framework
The 4-part prompt framework (Role, Context, Format, Constraints) that turns mediocre AI output into usable first drafts every single time.
The difference between AI answers you can ship and answers you have to rewrite isn't the model — it's the prompt. Use this 4-part framework and you'll fix 80% of bad output.
R — Role
Tell the model who it is. "You are a senior B2B copywriter" outperforms a blank slate every time.
C — Context
Give it the world: who the audience is, what already exists, what failed before. Paste the source material — don't summarize it.
F — Format
Specify the output shape: bullets, a table, JSON, 90 words, three options. Models follow format instructions almost perfectly.
C — Constraints
What to avoid: jargon, hedging, exclamation marks, em-dashes, the words "leverage" and "synergy". Negative instructions matter as much as positive ones.
A complete example
You are a senior B2B copywriter (R). I sell project-management software to ops leaders at 50-200 person companies; pain = chaotic Slack updates (C). Write 3 LinkedIn hooks, each ≤15 words, plain-text, no emojis (F). Avoid the words "revolutionize" and "game-changer" (C).
This framework powers the 50 prompts inside The AI Productivity Playbook — each one is R-C-F-C, just pre-filled for a specific job.
