## Overview

Kern Studio is a local-first desktop workspace for using the pi coding agent across projects. The main workflow is to discover a project, open an agent session (optionally in an isolated worktree), then inspect or deliver its changes through review, Kanban, and pipeline tools. Separate dashboards support restricted Deep Research and local knowledge features. The tree, README, and sampled command registrations support these major product areas; several subsystem connections are documented capabilities rather than inspected call sites.

Main entry points: [`src-tauri/src/lib.rs`](https://github.com/rfkokt/command-rdev-center/blob/main/src-tauri/src/lib.rs) (Native command host), [`src/App.tsx`](https://github.com/rfkokt/command-rdev-center/blob/main/src/App.tsx) (Workspace shell), [`src/components/ChatView.tsx`](https://github.com/rfkokt/command-rdev-center/blob/main/src/components/ChatView.tsx) (Agent chat), [`src-tauri/src/pi_rpc.rs`](https://github.com/rfkokt/command-rdev-center/blob/main/src-tauri/src/pi_rpc.rs) (Pi session runtime)
