Set Up 3 Custom Slash Commands That Turn Any Brainstorm Into a Critique, Summary, or Action Plan

Turn any brainstorm into a critique, summary, or action plan

3 ChatGPT Slash Commands

By the end of this guide, you'll have three custom slash commands set up in your AI chat — type /critique to stress-test an idea, /TLDR to compress dense text, or /ActionPlan to turn research into executable steps, all without retyping long prompts.

Who This Is For

  • You retype the same instructions over and over — "make this shorter," "give me steps," "what's wrong with this"

  • You brainstorm with AI but never pressure-test the ideas before acting on them

  • You paste in long research or articles and want them compressed fast

  • You end up with strategy but no clear next steps to execute

  • You want a faster, command-driven way to work instead of writing a full prompt every time

What You'll Build

Three custom slash commands, defined once at the start of a chat session:

  • /critique — Claude or ChatGPT acts as a brutal critic, naming exactly what's weak, confusing, risky, or missing

  • /TLDR — compresses dense text, research, or long answers into scannable bullet points

  • /ActionPlan — converts research or strategy into a simple, logical, step-by-step plan you can execute immediately

Once defined, each command works with a single keystroke for the rest of the conversation.

What You'll Need

  • ChatGPT or Claude (the technique works in both)

  • A brainstorm, block of research, or rough idea to work on

  • No tools, accounts, or installation required
