Claude Code is an agentic coding tool that lives in your terminal, understands your codebase, and helps you code faster by executing routine tasks, explaining complex code, and handling git workflows - all through natural language commands.
Fable 5-grade work discipline for any Claude model — a Claude Code skill + guard hooks (plan gate, model ceiling, per-task enforcement) that make Opus 4.8 or any non-frontier model plan, self-verify, and route sub-agents like Fable 5, without Fable 5.
