How To Actually Use Claude Fable (Without Hitting Your Limit)
A 20-minute breakdown of the 10/80/10 system and loop engineering — the cost-efficient way to run the most expensive AI model on the market.
June 11thA tutorial arguing prompt engineering is dying now that models are smart enough to self-correct — and a walkthrough of Claude Code's /goal, /loop, and /schedule commands with a live website-audit and YouTube-monitoring demo.
Prompting is being replaced by loop engineering: instead of manually re-prompting an AI turn by turn, you give it a defined goal, a checklist for what 'done' means, and a budget, then let it attempt, self-check, and retry the work autonomously.
Prompt engineering worked because you had to manually relay instructions and feedback to the AI every turn — you were the loop. New models like Claude Fable 5 are smart enough to evaluate their own output, so the shift is to 'loop engineering': define a goal (the mission), a checklist (what done means), an inspector (a grading pass), and a budget (a cap on tries or tokens), then let the AI attempt, self-correct, and retry on its own. In Claude Code this maps to three commands — /goal for a single mission with a finish line, /loop for a repeating interval, and /schedule for an exact clock time. The video demos both: a one-shot website-audit goal and a recurring YouTube-monitoring loop, then argues you should build trust in autonomous AI in stages rather than granting full autonomy immediately.

Cold open: prompting is dead, loop engineering is the new master class.

Explains context-window amnesia and why the human had to manually relay every instruction and correction under the old prompting model.

The new model class (Claude Fable 5, GPT-5.6) needs far less precise prompting because it can infer intent and self-evaluate.

The turning point: the human moves from being the middleman relaying feedback to standing outside the loop while the AI self-corrects.

The four pieces of a loop: spec/goal, checklist, inspector, and budget.

Inner loop (a single self-correcting mission) versus outer loop (a recurring routine that fires inner loops on a schedule).

/goal is a single mission with a finish line; /loop is a repeating routine; deliverables must be explicit for a loop to know when to stop.

Live Claude Code demo: a /goal audits milesdeutscher.com.au like a paid conversion consultant, fetches raw HTML, and writes ranked findings to roast.md.

A YouTube-monitoring /loop demo plus a spreadsheet of ~20 loop ideas across content, marketing, business ops, sales, finance, and personal productivity.

/schedule for exact clock times, stopping/cancelling loops, and the Trust Ladder for building autonomy gradually.

The shift from prompting to looping means success now depends on specifying a clear finish line and letting the model self-check, rather than on wording a clever instruction.
“So AI is a genius, especially these new models. They're so smart. They're brilliant at every single task.”
“So before you were in the loop, now you're outside of the loop.”
“Instead of micromanaging the laborer, you can basically just hire a contractor in these new models to do the work for you instead.”
“Just like a real employee, it needs to be properly onboarded.”

Prompting, the creator argues, is basically dead — not because AI got worse at following instructions, but because the newest models got smart enough to stop needing a human in the loop at all. What replaces it is a set of Claude Code commands (/goal, /loop, /schedule) that let an AI attempt a task, grade its own work, and retry until it hits a defined finish line.
The minimum components required for an AI loop to run autonomously and know when to stop.
Distinguishes a one-shot self-correcting task from a recurring scheduled routine; outer loops can contain inner loops.
The three Claude Code commands and what each one controls.
A four-stage progression for how much autonomy to hand an AI agent, likened to onboarding a new employee rather than handing over the company card day one.
