About fable-method

The Fable Workflow How Claude Fable 5 worked, written down before it was gone. With the eval that keeps it honest. In its final days before deprecation, Claude Fable 5 distilled its own way of approaching problems into a set of skills any model can run: classify the ask before touching anything, define done with a named verification, gather evidence in parallel from primary sources, commit to one recommendation, change the smallest correct thing, verify by observation, report the outcome first with honest caveats. Then it tested that distillation against itself, adversarially, across 159 agent runs, and kept the failures in the log. Most agent instruction files tell the model what to value ("be careful, verify your work"). This one tells it what to do, in what order, with thresholds, so a mid-tier model can follow it literally. Three skills, one philosophy: think (fable-method), act (fable-loop), prove (fable-judge). Every rule exists because a test failed without it; ever

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.
