Documentation

Ryx Sidekick

Your AI coding agent, inside the Unity Editor.

Chat with Claude right in Unity — Unity-native context, streaming replies, and safe, reviewable edits.

Ryx Sidekick integrates the Claude Code CLI directly into the Unity Editor. Bring your own Claude subscription or API key, attach project and scene context, and review every edit before it touches your files.

✨ Features

💬 Streaming chat — incremental stream-json responses, rendered with full Markdown (code blocks, tables, links).
📎 Unity-native context — attach files, the current selection, and GameObjects (hierarchy path + components) so the agent understands your project.
🛡️ Safe, reviewable edits — plan first and approve the plan card (Accept / Adjust / Deny), a permission prompt for every controlled action, plus Files and Diff tabs with per-file revert.
❓ Questions, not guesses — when the agent needs a decision it asks in a tabbed prompt you answer right in the Editor.
🖼️ Image attachments — paste, drag & drop, or capture Scene / Game View screenshots, with a zoom & pan overlay.
🗂️ CLI-native history — browse past conversations straight from the CLI's local store (read-only — your history files are never modified).
⌨️ Command palette — a VS Code-style palette that also auto-discovers the CLI's slash commands.
🧠 Models & extended thinking — pick Sonnet / Opus / Haiku (or a custom model) and toggle extended thinking.
🔌 MCP for Unity (optional) — deeper, tool-like workflows via a generated or custom MCP config.

🔁 One Claude history, wherever you work

The same code-review session open side by side in Sidekick, a terminal, and an IDE

Sidekick reads the Claude CLI's own local session store — and never rewrites it. Start a turn in Unity, resume it in your terminal with claude --resume, finish it in your IDE. No lock-in, no second copy of your history.

✅ Requirements

Unity 6000.0+ (Unity 6)
The Claude Code CLI (claude on your PATH)
An authenticated Claude account — a Claude.ai subscription, an Anthropic Console API key, or your own Bedrock / Foundry / Vertex provider

The Sidekick sign-in screen offering Claude.ai Subscription, Anthropic Console, and Bedrock, Foundry or Vertex

Sidekick has no account and no subscription of its own — you sign in with the Claude account you already have.

Dependencies (com.unity.dt.app-ui, com.unity.nuget.newtonsoft-json) resolve automatically from the Unity registry — no scoped registry required.

📦 Installation

In Unity: Window → Package Manager → ➕ → Add package from git URL… and paste:

https://github.com/Vidosen/ryx-sidekick-lite.git#v2.7.0

Or add it to Packages/manifest.json:

"com.ryxinteractive.sidekick": "https://github.com/Vidosen/ryx-sidekick-lite.git#v2.7.0"

Omit #v2.7.0 to track the default branch.

Download RyxSidekick-Lite-OSS-2.7.0.unitypackage from the latest release and import it via Assets → Import Package → Custom Package…. It runs a one-time installer that places the package under Packages/, cleanly replaces any previous version (with rollback on failure), and then removes itself.

Use one install method — the git URL or the .unitypackage, not both (mixing them leaves two copies of the package).

🚀 Quick start

Project Settings → Ryx Sidekick → click Validate CLI (fix CLI Path if validation fails).
Window → Ryx Sidekick → log in if prompted.
Add context (files, selection, screenshots), type, and chat.

⭐ Ryx Sidekick Pro

Lite ships the Claude provider. Ryx Sidekick Pro adds the Cursor and Codex CLI providers and live MCP server management — one window, your choice of agent.
