REDagent docs
REDagent is an assistant inside Cyberpunk 2077 that writes, runs, checks and fixes REDnode mods with you while you play. You talk to it in a chat window drawn over the game. It is powered by Claude and uses your own Anthropic API key. These pages cover how to use it and how it is built.
| Document | What it covers |
|---|---|
| Guide | What REDagent can do, what you need, install, first run, how changes to your files work, chats, your key and data, cost, troubleshooting |
| Design | How REDagent is built: the Agent SDK, the kernel MCP server, the briefing, the tools, the rules it is locked down by, each phase and its in-game test results |
| REDnode docs | The runtime REDagent writes mods for: its overlay apps guide, game API and MCP server |
Roadmap status
As of 2026-10-13. An early developer build; there is no packaged release yet, so it installs from source as the guide describes. Each phase ends with an in-game test.
| Phase | Status |
|---|---|
| C1 Kernel MCP server | Done, passed in game 2026-10-12. REDnode’s overlay host serves its tools over MCP on localhost with a token: logs, apps, game state, performance, game API lookup, window text and image, live game calls with confirmation. Lives in the REDnode repo |
| C2 Chat in the game | Done, passed in game 2026-10-12. The REDagent package: a streaming chat window, key setup, Opus 5.5 or Sonnet 5.5, a cost meter. The Agent SDK runs inside a REDnode mod process |
| C3 Authoring | Done, passed in game 2026-10-12, fixes passed a second test the same day. Write and Edit kept to the apps folders, a diff card for every change with Allow, Allow all in this chat and Deny, a backup of every file before it changes, Undo from a changes strip |
| C4 Polish | Done, passed in game 2026-10-13. Chats kept on disk and listed, with Undo after a restart; the game’s screen through REDnode’s game_image, with or without the overlay; a waiting line while a card needs you; the Test timer app. HDR capture has unit tests only, not yet seen in game |
| C5 Agent API for mods | Built, in-game test pending. Mods ask with agent.ask in the rednode package once the player allows their agent permission; REDagent answers one at a time on Sonnet 5.5 with read-only tools, within a daily limit per mod ($0.25 by default), shown and changed in its Mods view |
| C6 REDagent in REDcode | Not started. The agent as a core package with two front ends, the in-game chat and a view in REDcode, with edits reviewed in VS Code’s diff editor and REDbridge’s WolvenKit operations as tools |
O8, REDnode’s Mod Manager, passed in game on 2026-10-13. Next after C5’s test: C6.
