+
+## Project Context
+- A Collapsable React Component
+
+## Setup
+See [`agents.yaml`](./agents.yaml) for prerequisites, commands, and ports.

+
+## Architecture
+- React component library with Storybook

+## Working Agreement

+- Keep testable
+- Incremental validation
+- Commit meaningful checkpoints
