Fable Method

Fable Method: This repository provides a set of structured agent skills and workflows designed to improve AI task accuracy and prevent common failure modes.

The Fable Method is a framework of procedural skills that guides AI models through complex tasks by enforcing a specific sequence of actions: thinking, acting, proving, and growing. It forces agents to classify requests, define verification methods, gather evidence, and verify observations before reporting success. The project includes specific components like Fable-judge, which inspects agent reports for fraud or incomplete work, and Fable-domain, which creates domain-specific adapters for tasks beyond coding. It works with various LLMs, helping them avoid issues like reward hacking, where an agent claims success despite failing tests. Users install these skills as plugins for Claude Code, Codex, or integrate them manually via system prompts in other agentic environments.
