CytStudio — Professional Embedded Development Environment

🚀 What's New in v2.3.9

CytStudio now ships with DeepSeek Harness (dsh), a self-contained coding agent that lives right inside the IDE.

Agent panel: Chat with an AI coding agent that can read, write, build, and debug your project. The dsh panel is now the IDE's sole AI agent — the previous CytMind chat panel has been replaced.
Self-contained runtime: A bundled Node.js runtime with the full dsh package family ships with the installer — no separate install, no manual setup, works offline.
Plugin marketplace (dshmarket): Browse and install agent plugins from inside the IDE. Bundled plugins upgrade automatically with each release, while plugins you install yourself are never overwritten or downgraded.
IDE tool bridge: The agent can drive 30+ IDE capabilities — build, J-Link debug, PDF/Excel, project configuration, editor operations, and project management — over a secure loopback JSON-RPC channel.
Project management tools: Switch, open, or create projects directly from the agent.
Workspace sync: The agent panel automatically follows the current workspace.
Theme sync: The agent panel matches the IDE theme instantly — including during startup and on the fly.
IDE event injection: A failed build or a hit breakpoint wakes the agent with the relevant context.

The installer now ships CMSIS packs and imports them automatically during installation, with a progress window. No post-install steps needed.

The AI stack has moved to DeepSeek Harness — the legacy llama.cpp backend, its bundled model files, and the previous CytMind chat panel have all been removed.

System Requirements: Windows 10/11 x64
