Mythos Scaffold · kasparovabi bundle Push Opus 4.x-class and smaller models toward Mythos/Fable-grade agentic behavior. Kernel of Fable-distilled patterns (decomposition, verification, next-action, context economy) plus demand-loaded skills, persistent mission files, named sub-agents, enforcement hooks, and domain modes (research, migration). Use when starting complex multi-step work, long-horizon tasks, or anything needing systematic persistence and verification. Do NOT fully load on Claude 5 models (Fable 5 / Mythos 5 / Opus 5 and later); over-scaffolding degrades them.
