fable-mode

fable-mode is an Agent behaviour & coding discipline skill for AI agents, published by cozytab in the fable5-mode repository on GitHub. Skillspace rates fable-mode D (68/100) and it passed the safety scan; the rating is based on static analysis only.

A work-discipline protocol that makes Opus 4.8 (or any non-frontier model) operate at Fable-5-grade quality. Core idea — output quality = model capability x work discipline: spend extra orchestration to buy single-pass quality via six levers (plan gate, small-card execution, adversarial self-check, real-product verification, context hygiene, checkpoint autonomy). Activate ONLY on an explicit request — the user names the mode ("use fable mode", "enable fable-mode", "work like Fable 5", "rigorous mode", or the Chinese "用 fable 模式"、"开 fable-mode"、"像 Fable 5 一样做"、"严谨模式") — or when the project is already armed with a `.fable/` directory (the hooks handle that). Do not auto-trigger on a task merely being large, important, or quality-sensitive, and not on generic phrases like "do it well / 最高质量 / 别偷懒"; if a task looks like it would benefit, ask the user whether to enable fable-mode instead of assuming.
