Pro Features

Sidekick Pro is an extension package (com.ryxinteractive.sidekick.pro) that adds advanced AI CLI providers on top of the free Lite base. It requires Sidekick Lite 1.3.5+.

One-time purchase — no subscription.

Included providers

Cursor

The Cursor provider connects to the Cursor CLI via the Asynchronous Call Protocol (ACP) — a persistent JSON-RPC session over stdio. This means Cursor keeps context across turns without restarting the process.

Key capabilities:

• Provider-scoped streaming with thinking/content/tool events
• Persistent session with reconnect on domain reload
• History reader for ~/.cursor/projects/ agent transcripts

Codex

The Codex provider integrates with the OpenAI Codex app-server over a JSON-RPC transport. It includes:

• App-server lifecycle management (start/stop, MCP config injection)
• Plan-mode streaming with incremental plan items and ExitPlanMode traces
• AskUserQuestion round-tripping with collapsible traces in the chat UI
• History reconstruction from session index + file fallback

Installation

1. Ensure Sidekick Lite 1.3.5+ is installed.
2. Add com.ryxinteractive.sidekick.pro via the Asset Store.
3. The [InitializeOnLoad] bootstrap (SidekickProBootstrap) automatically registers the Cursor and Codex providers — no manual configuration required.
4. In Project Settings → Ryx Sidekick, select your provider from the Provider dropdown.

Upcoming Pro features
