Anthropic posted a FULL GUIDE on how to prompt Fable 5 (Mythos).
Claude Fable 5 is not meant to be prompted like any other model.
It's meant to run autonomously.
Here's exactly how to enable Fable to do work for you with minimal manual intervention:
1. Effort selection
Anthropic recommends using High for most tasks and Xhigh only for complex workflows.
Low/medium: quick questions, basic research
High: default for most work
Xhigh: complex builds, multi-step analysis
Ultracode: full autonomous orchestration
2. /loop prompting
Use /loop prompts to kick Fable off to complete full tasks.
/loop <time interval> + <goal>
3. Tell it WHY, not just what (context)
Fable can't perform on instructions alone. It needs context to make decisions on its own.
Anthropic's exact prompting structure:
"I'm working on [larger task] for [who it's for]. They need [what the output enables]. With that in mind: [your actual request]."
4. Keep prompts short (instructions)
Counterintuitive but critical.
Over-engineering your prompts on Fable 5 degrades output. You're constraining a model that would have figured it out on its own.
4. Tell it when to stop and check in during runs
"Pause for me only when the work genuinely requires my input: a destructive action, a real scope change, or something only I can provide. Otherwise, keep going and report back when done."
5. Build it a memory system
Fable performs best when it can record lessons from its previous loops.
Give it a markdown file and this instruction:
"Store one lesson per file with a one-line summary at the top. Record corrections and confirmed approaches. Don't save what the repo or chat history already records."
The optimal general prompt structure:
"Goal: I'm working on [larger task] for [who it's for]. They need [what the output enables].
Request: [your specific ask in one sentence]
Output format: [exactly how you want it]
Constraints: [what must not happen]."
One last thing - your old prompts may actually work against you.
Skills and project instructions built for Opus 4.8 may produce worse results on Fable.

🚨 SHOCKING: An ex-Anthropic researcher just leaked the exact internal prompting framework the team uses.
Most people treat Claude like a basic chatbot and leave 60–70% of its reasoning power on the table.
These 10 prompts are how the pros actually use it — tested internally for maximum clarity, honesty, and depth.
Copy-paste ready. Zero fluff.
Save this thread. Your Claude game is about to change forever.
(Pro tip: use them in order for compound results)
1. Complete Presentation Blueprint
"Act like a professional presentation consultant who has built decks for Fortune 500 boardrooms and billion-dollar pitch meetings. Create a complete presentation blueprint for [topic]. Define the objective, target audience, key message, emotional arc, and exact slide flow. Make every section earn its place and eliminate anything that loses the audience for even a single second."
The biggest waste of talent in Singapore 🇸🇬 is watching high performers from elite high schools become financial advisors
If you’re mid, fine. You were probably going to be mid anywhere
But if you’re actually sharp & ambitious,
why the hell would you spend your 20s selling insurance policies?
That’s not a career path. That’s a talent drain with no leverage, no upside, and no pride
Abstract probably won't change anything now, because apps/NFT collections that are leaving chain not generating revenue for them
Abstract is still feeling good because of strong believers who're still spending a lot of funds on farming XP
But this can't work forever, one day this "pay for XP" model will stop working
@loshmi Farming and draining from the community without giving real value back. Keeping small circle within the privileged few. Gaming, gambling fatigue. No wonder projects migrating.
honestly it makes me very sad to see Abstract doing this bad compared to how it was in 2025
especially since Abstract was one of the most fun times I've had in web3 as well
what could possibly bring back Abstract as a trending topic again?
i am guessing majority will just say TGE
but is there anything building on Abstract right now that could bring back fun and bring more eyes or no?

I don’t game. I don’t gamble. Not exactly an NFT enthusiast either (since degod days, gave up). And I sure don’t stream.
Great disadvantage in every aspect for people like me on this chain. I see people rewarded greatly doing all of these things. I do too. And I spend. Generously. Still.
Some people I know dislike doing some of these things, but they do it for xp. The end result? Farming-Fatigue. It’s a real thing. Look at OpenSea.
There’s also “the inner-circle”. To be seen, heard and felt. If you’re not the usual few? Then too bad. You’re a nobody. Doesn’t matter what you do. You just don’t “suck up enough” or “vibe-enough”. Just Too bad.
Not everyone has time or means to “travel” or “meet” or attend a damn live call session. There are people from different cultures, diff time zones and diff part of the world. Some are just simply “digital introverts”. So what?
So perhaps these are some of the many reasons. @Noriil_ expressed it well.
For me, I’m at the stage of “whatever”….
