Fable 5-grade work discipline for any Claude model — a Claude Code skill + guard hooks (plan gate, model ceiling, per-task enforcement) that make Opus 4.8 or any non-frontier model plan, self-verify, and route sub-agents like Fable 5, without Fable 5.

# fable-mode

**English** | [简体中文](README.zh-CN.md)

**A work-discipline protocol that makes Opus 4.8 (or any non-frontier model) operate at Fable-5-grade quality.**

fable-mode is a [Claude Code](https://claude.com/claude-code) skill plus a set of
guard hooks. Its premise:

> **output quality = model capability × work discipline**
