Steal the 5-line brief.fill in the blanks, hand over the whole job.
Anthropic shipped its smartest model this week. Its lead grows with task length — so the skill isn’t clever prompting anymore. It’s a clear brief. Here’s ours.
Why briefs beat prompts
The receipt: Stripe pointed Fable 5 at a 50-million-line codebase. A migration scoped at two-plus months for a whole engineering team shipped in one day. That’s not a chatbot — that’s staff. And staff doesn’t run on one-line questions. It runs on briefs.
The 5-line brief — fill in the blanks
JOB: Audit why our /services/seo page stopped ranking and write the fix list. CONTEXT: [Search Console screenshot] [GA4 screenshot] [the page URL] [top 3 competitor URLs] CONSTRAINTS: Our voice doc attached. No new tools, no rebuild — work with the page we have. DONE = A prioritized fix list I can hand to my designer, with the why behind each item. EFFORT: Check your own work against the screenshots before you show me.
The other two moves from the manual
Give it a notebook. Persistent memory files made Fable 5 improve 3× more than the previous model in Anthropic’s tests. Keep a brand file, a voice file, and a past-work folder — and let it take its own notes between sessions.
Stop describing, start showing. Its vision rebuilt a working app from screenshots alone. Screenshot your Search Console, your GA4, the SERP you’re losing — drop the image in and ask what it sees that you don’t.
The fine print everyone skipped: Fable 5 is included on paid Claude plans only through June 22, 2026. After that, the meter starts. Learn the manual while it’s free.
