If you still don't understand loop engineering, you'll want to save this.

It's the most powerful way to prompt Fable 5.
How to get started with loop engineering (as a non-technical beginner):
First, you need some context about what loop engineering actually is.
For the last two years, using an AI agent looked like this:
You write a prompt → you read the response → you write the next prompt → you read that response → repeat.
Essentially, you're the one holding the wheel the whole time.
Loop engineering flips that completely - Instead of prompting the agent by hand at every step, you design a system that prompts, checks, remembers, and re-runs the agent for you.
TLDR: You stop being the person typing prompt instructions.
Every loop is built from three core pieces:
→ The goal: the success condition you're working toward.
→ The loop itself: the repeating cycle. It can run a fixed number of times or run until a condition is met.
→ Routines: predefined chunks of behavior the agent can call whenever it needs them (think of these as subroutines it reaches for mid-task).
How to get started with loops:
Pick one small, repeatable task. Not your whole workflow, one piece of it.
• Define the goal in plain language.
• Set a ceiling. Max attempts or max time, always.
• Let the agent run the loop: act, observe the result, decide the next move, repeat.
• Review the output and iterate if needed.
The easiest way is to type "/loop" inside Claude Code and start setting your success/task criteria.
