oh-my-fable — Fable 5's way of working a long task (plan first, self-correct, never lose the thread), as a model-agnostic agent harness. The run lives in one serializable RunContext, checkpointed every step, so a crash is a pause. Zero deps, deterministically testable.

fable-mode

Run Claude Fable 5 on Opus 4.8 in Claude Code. The Mythos-class model pulled by export controls — brought back as a system prompt. One clone + install: leaked Fable 5 prompt, a measured execution playbook, test-after-edit + grounding hooks, and design/MCP/test skills. "Fable 5 Lite," done right.
