README

Excerpt

Developing PenguinHarness

PenguinHarness is a TypeScript monorepo: an Agent SDK (packages/core), an HTTP server (packages/server), a Web App (packages/web), a CLI (packages/cli), an Electron shell (packages/desktop), the landing and docs sites, and the shipped skill library (packages/skills). It consumes LLM providers through @prismshadow/agenthub and implements no provider clients of its own.
