Fable 5 Is Back. Here's What I Shipped With It

Claude’s Fable 5, the model built for heavy, long-horizon work, is on the menu again. The window closes on July 7, 2026, so this is a short one: five fill-in-the-blank prompts I put together, and what happened when I ran two of them myself.

Fill in the brackets, paste, and let it run.

01. Ship a portfolio site

Drop your CV in the root folder. Fable reads it and ships a responsive, deploy-ready site.

Build my portfolio site, my CV is in the root folder. Pull my info
from it. About, Projects, Skills, Contact. Use [Neo-Brutalism /
Utilitarian / Minimal] design style, add animation, keep it
responsive, and deploy-ready.

This one isn’t hypothetical: the website you’re reading right now came out of this prompt. It pulled my roles, skills, and projects straight from the CV, and everything since (the blog, the photo albums, the deploy pipeline to my server) grew out of that first run.

02. Own your time and tasks

Tasks, pomodoro, alarms, a habit tracker. Fable wires the state and persists it locally.

Build a productivity app with [tasks / pomodoro / habits].
Style: [bento]. Persist data [locally]. Priority feature:
[the one you care most about].

Also not hypothetical: this became Bento Focus, the dashboard I now keep open all day. One HTML file, works offline as a PWA, and it’s live on its own subdomain.

03. Clone paid apps locally

Point Fable at an app like Notion, Linear, or Todoist and rebuild its core feature as a private, single-user tool that runs entirely on your machine. No auth, no payments, no subscription.

Build a local, self-hosted clone of [Notion / Linear / Todoist]
with its core feature: [the one you use most]. Skip auth and
payments. Single-user, runs locally.

04. Hunt real bugs in your repo

Bug-finding is where Fable 5 pulls ahead. Fan it across your repo to surface real bugs: logic errors, race conditions, security holes. Each with a fix and a severity score.

Scan my repo [path] for real bugs: logic errors, race conditions,
security issues. Focus on [module]. For each: explain it, show
the fix, rate severity.

05. Watch every cron job

Give Fable your job names and schedules. It builds a lightweight monitor that alerts you when a job fails, stalls, or runs long, with one dashboard for status, last run, and logs.

Build a cron-job monitor. Track [job names / schedules], alert me
if a job [fails / stalls / runs long], show a dashboard of
[status / last run / logs].

The window closes July 7

Five prompts, one weekend of long-horizon work. Two of them already earned their keep for me: you’re looking at the first one, and the second one is a subdomain away. Queue the rest before Fable 5 winds down.
