fable-mode English | 简体中文 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 skill plus a set of guard hooks. Its premise: output quality = model capability × work discipline Quickstart The skill works on its own; step 2 is optional (it turns the discipline into hard blocks). Claude replies in your language even though the skill is authored in English. Design intent & what it changes Why it exists. Weaker models mostly don't fail by being dumb in the moment; they fail by process: thinking while typing and changing their mind halfway, declaring "looks right" without running anything,

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
