Five skills written by Claude Fable 5, the smartest model Anthropic has ever shipped, before it leaves your plan.
You can't keep the model. You can keep its playbook. Each skill is Fable's own working method written down as a manual, so every model that comes after (Opus, Sonnet, whatever's next) reads it and holds itself to the same standard.
| Skill | Job | Fires when |
|---|---|---|
The Bouncer (bouncer) |
Pre-ship security check. Nothing goes live without getting checked at the door. | You deploy, publish, or say "is this safe?" |
The Foundation (foundation) |
Starts projects so they still make sense in a month. Skeleton before features. | Any new project or build begins |
The Architect (architect) |
Asks the questions that change the build, then writes a plan a smaller model can execute solo. | "Plan this", or any multi-step feature |
The Straight Shooter (straight-shooter) |
Your plan critiqued with the yes-man switched off. Verdict first, then the math. | "What do you think?", "Be honest" |
The Lie Detector (lie-detector) |
Catches "fixed!" when it isn't. Reproduce, prove the fix ran, re-run, paste output. | Any fix claim, any "should work now" |
Open Claude Code (or Claude Cowork) and say:
Install the skills from https://github.com/tenfoldmarc/fable-five for me
git clone https://github.com/tenfoldmarc/fable-five.git /tmp/fable-five && \
mkdir -p ~/.claude/skills && \
cp -R /tmp/fable-five/bouncer /tmp/fable-five/foundation /tmp/fable-five/architect /tmp/fable-five/straight-shooter /tmp/fable-five/lie-detector ~/.claude/skills/That's it. The skills trigger automatically when their moment comes, or you can call them by name: "run the bouncer on this", "architect this feature", "straight shooter: here's my offer."
Copy each of the five skill folders (bouncer, foundation, architect, straight-shooter, lie-detector) into the user's skills directory (~/.claude/skills/ for Claude Code, or the project's .claude/skills/ if they prefer project-level). Each folder contains a single SKILL.md. No dependencies, no setup, no API keys. Confirm to the user which five skills were installed and give a one-line description of each.
No. That's the whole point. The skills were written BY Fable, describing how it works. Any model that can read follows them. They raise the floor of whatever model runs them.
A full project lifecycle using all five:
- Foundation sets up the project so it won't rot.
- Architect interviews you and writes the plan.
- Your everyday model builds, step by step.
- Lie Detector verifies every fix along the way with real evidence.
- Bouncer checks the door before anything ships.
- Straight Shooter tells you whether the thing you built should exist at all.
