Ryx Sidekick Pro - your AI agent for Unity screenshot 1
About this asset
The complete Ryx Sidekick. Claude, Cursor, and Codex in the Unity Editor — with everything that makes Sidekick a real workflow tool: streaming chat, deep project context, safe reviewable edits, Skills, and live MCP management. One package, one-time purchase.
Bring your own agents. Keep your existing subscriptions or keys — Pro never resells inference, you pay your provider directly.
One download, nothing else to buy. Pro ships as a complete bundle that includes the base package — install it and you have the full product.
Everything in one package
All three providers
- Claude, Cursor, and OpenAI Codex — run any of them inside Unity.
- Switch provider per session without losing your draft or session state.
- Use your own subscription or keys for each; pay your provider, not us.
Core workflow
- Chat inside Unity — streaming responses, Markdown, syntax-highlighted code blocks, one-click copy.
- Command palette — VS Code-style slash commands, built-in actions, discovered CLI commands, and @-mention asset attachments.
- Rich context — attach project files (text/binary detection, truncation), GameObjects (hierarchy + components), and one-click Scene/Game View screenshots; paste or drag & drop images.
- Safe editing — permission modal with diff previews, permission modes (ask / plan / auto), and a Changes view with one-click revert.
- Conversation history — reads your CLI's native local history; the last chat is restored per project; in-flight responses survive domain reload.
- Auth your way — Claude.ai subscription login, Console API key, or provider routing (Bedrock / Vertex).
Pro power tools
- Skills — your user, project, and plugin skills as slash commands, in a dedicated palette section.
- Live MCP management — real-time MCP server status, tools, and resources for every provider, as a read-only inventory with secret masking.
Pricing
- $49.99 — one-time purchase, no subscription.
- Own your edition forever; 1 year of updates and support included.
