Fable 5.2

What to do with Fable 5.2 before Monday

One prompt, it interviews you, then writes your Instructions and your plan, and both stay after the model leaves your plan.

Before You Paste

01Open ClaudeOn the web or in the app, whichever you use every day.
02Pick Fable 5.2Open the model picker and choose Fable 5.2. It is not chosen for you. Set the effort to High, as in the video.
03Start a new chatA fresh one, so nothing earlier in an old chat gets in the way.

Dictate or type long answers, because the more it knows, the better both documents are. It never needs a client's name or anything confidential.

Paste this into the new chat

I have Claude's biggest model for a few days, and I want to spend it on one job that lasts. Interview me about my business until you understand it well enough to advise me properly. Ask one question at a time, follow whatever seems most worth following, and push back when an answer doesn't add up. You don't need client names or anything confidential, so remind me not to share them. When you know enough, write me two things to keep. First, my Instructions for Claude. This is what every future chat will read before it starts, on smaller models than you, so write what they would need to work the way you would for me. Keep it under 250 words, short enough that every line earns its place, and put it in a code block. Second, a step by step plan to get me where I told you I want to go, starting with something I can do this week. Use your own judgement about what matters. I want your thinking, not a template. Finish by telling me to paste the Instructions into Settings, then Your Claude, then Instructions.

Why This And Not Questions

Anthropic's own advice is to start most work on Opus 5.5 and go up to Fable for the big, hard jobs. So the window is worth one big job whose result lasts. Instructions are read before every conversation, so whatever writes them sets the standard for every chat after.

The Honest Bit

On a Pro plan, or a standard seat on a Team plan, Fable models are included in the plan's weekly usage limits from 9 November 2026 through 16 November 2026 at 11:59 pm Pacific time. That is 07:59 on Tuesday 17 November in the UK.
During that week you can use up to 50% of your weekly usage limits on Fable at no extra cost. Fable uses the limit faster than other models, so do this job first.
Afterwards Fable is not taken away. On those plans it goes back to running on pay-as-you-go usage credits on top of the plan. Max and Ultra plans keep Fable included, for up to half their weekly limit.
Claude can switch a conversation from Fable to Opus on its own partway through, and the model picker then stays on Opus. Glance at the picker before the long answers and switch back if it has changed.
The prompt works on any Claude model. If you are reading this after Monday, run it anyway on the model you have.
Instructions apply to your own account. On a team, each person pastes their own.
In July the date for the previous Fable moved twice, so this one may too. The job is worth doing either way.

Custom instructions covers what to put in that box, what to leave out, and a shorter interview that writes just that.
Have Fable interview you is the wider version, for your whole situation rather than your business.

Let's set up your agent ecosystem.

This page is one job. The whole thing is a set of them running off the same foundation, the folder your AI works out of, the brief on how you like things done, the accounts it can reach and the skills that run off all of it, so your admin gets done the way you would do it. It is what I teach one to one, on your own machine and against your own work, and the quickest way to find out what yours would look like is a proper chat about it.
