+# Agent Studio Mini
+
+Training-grade Agent Harness built with Pi Coding Agent SDK, Fastify, SSE, React, and assistant-ui.
+
+The project is under active construction. Verified setup, security guidance, and demo instructions are added with the completed implementation.
+
+## Verified dependency baseline
+
+- Node.js 22.22.3 (Pi 0.85.1 requires Node.js 22.19 or newer)
+- pnpm 11.7.0
+- TypeScript 5.9.3 (the newest release supported by typescript-eslint 8.69)
+- Pi Coding Agent SDK 0.85.1, using `typebox` 1.3.7
+- assistant-ui React 0.15.18
+
+The original brief allowed Node.js 20+ and referred generically to the current TypeBox package. The installed Pi release has a higher Node.js floor and directly uses the `typebox` package rather than `@sinclair/typebox`; this project follows the installed public types.
