English | 한국어 fablize — run Opus like Fable A Claude Code plugin that makes Opus (or any Claude model) see a task through to the end — with evidence and verification — as procedure, not as luck. Why When Fable 5 shipped, I ran a controlled comparison of Fable 5 and Opus 4.8 (an A/B set of 19 runs plus 26 real working sessions, 1,500 tool calls). The finding: On closed, answer-bearing work (code, logic, builds), the two models were effectively tied. The gap appeared only on open-ended work, and its nature was "following an implication one step further." That depth is model capability — it could not be transferred by instructions or a harness. An injection experiment confirmed it: Opus could not reproduce the defects Fable found on its own. But the procedure of good work — actually running what you build, seeing it through, investigating systematically — does transfer. fablize applies only the procedures whose effect was verified. It does not raise the model's ceiling; it makes the model reach its own ceiling. What transfers and what doesn't A procedure Opus skip

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.
