From the README
<div align="center"> <p> </p> # pi-fabric **A programmable tool and agent runtime for [Pi](https://github.com/earendil-works/pi-coding-agent)** _One program for tools, MCP, agents, workflows, actors, mesh, councils, and recursion._ <p> </p> <p align="center"> 🏆 <strong><a href="https://arcprize.org/scorecards/d4c56c67-136b-4643-b648-62ae28fe2a54">100% on ARC-AGI-3</a></strong>. A Fabric-powered agent won <strong>all 25 environments</strong> in one 22.4-hour session with 4 minutes of human time ($1,349 in model spend). </p> </div> --- Fabric gives Pi one programmable tool called `fabric_exec`, which composes core tools and MCP servers with captured extension tools. The default kernel runs checked TypeScript in isolated QuickJS; select sandboxed **Python (Monty)** with `executor.kernel: "python"`. CPython is an explicit native escape hatch via `executor.pythonRuntime: "cpython"`. The configured kernel is exclusive: there is no per-call language selector.
