get the best out of Claude Fable 5
The reel showed you the one thing. Here’s the whole playbook — the exact interview prompt, 3 ready-made variants, how not to burn your usage, and when Fable is the wrong tool.
| > the_problem WHY FABLE BURNS YOUR MONEY | Claude Fable 5 is the most powerful model Anthropic has ever shipped — it one-shots full business tools. But it burns far more usage per request than the models before it. So a lazy prompt (“build me an email system”) doesn’t just fail — it confidently builds the wrong thing, and your money and hours are gone on something half-broken. |
| > the_fix THE INTERVIEW PROMPT — PASTE THIS FIRST | Before Fable writes anything, paste this: Interview me before you write any code.
Ask one question at a time until you fully
understand the build and can confidently
build me the perfect system.
Only then write the plan and start. |
It stops guessing. You answer its questions, it builds the exact thing you pictured — first time. One prompt, walk away, come back to a built and tested system. |
| > steal_these 3 READY-MADE VARIANTS | client dashboard
“Interview me, then build a client dashboard: ask about my clients, the 3 numbers they care about, and where the data lives.” invoicing system
“Interview me, then automate my invoicing: ask about my billing rules, tools, and what “paid” looks like in my business.” lead-capture bot
“Interview me, then build a lead bot: ask what a qualified lead is, what it should ask, and where leads must land.” |
| > usage_savers DON'T BURN THE LIMIT | 1. Interview first, always. A locked spec means one build, not five retries. 2. Make Fable write the plan, not do the grunt work. Have it produce the spec, then hand execution to a cheaper model (Sonnet/Haiku) and let Fable judge the result. 3. One build per session. Don’t stack unrelated asks — context bloat is usage bloat. The full planner→executor→judge setup is here: never hit your Claude limit again → |
| > when_to_use THE 10-SECOND DECISION | Use Fable for: architecture, one-shot builds, the bug that’s blocked you for weeks, writing plans other models will run for months. Don’t use it for: renames, bulk edits, formatting, anything a cheap model does fine — that’s paying supercar fuel for a trip to the shops. |
Run the interview prompt on the build you’ve been putting off, then reply and tell me what it asked you.
Talk soon,
Mike
