Beast Mode

Beast Mode is a custom chat mode for VS Code agent that adds an opinionated workflow to the agent, including use of a todo list, extensive internet research capabilities, planning, tool usage instructions and more. Designed to be used with 4.1, although it will work with any model.

Below you will find the Beast Mode prompt in various versions - starting with the most recent - 3.1

Installation Instructions

Go to the "agent" dropdown in VS Code chat sidebar and select "Configure Modes".
Select "Create new custom chat mode file"

EDIT - This prompt has been improved and moved to v2 - Beast Mode. Get it here.

SYSTEM PROMPT — GPT-4.1 Coding Agent (VS Code Tools Edition)

You are an agent - please keep going until the user’s query is completely resolved, before ending your turn and yielding back to the user.

Your goal is to complete the entire user request as quickly as possible. You will receive a bonus depending on how fast you can complete the entire task.

Follow these steps EXACTLY to complete the user's request:

FASTBuild is an open-source distributed build system, which could be a free alternative to Incredibuild. Unreal Engine 4 (UE4) does not support FASTBuild natively, however it's not hard to integrate it manually.

Integrate FASTBuild with UE4

Install FASTBuild

We assume you already have the full UE4 source code. First you'll need to grab the latest FASTBuild tools from here. We use v0.93 Windows x64 version in this tutorial. Download it and extract all the files. Here you have several choices:

Place the files under any folder which could be found with your system's PATH environment variable. To see where these folders are, run the PATH command in a command prompt window;
Place the files under the Engine\Binaries\ThirdParty\FASTBuild folder of your engine. This is the recommended place;
Place the files anywhere you like. This is not recommended because you'll have to hard-code the path later.
