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"
export const chaosTestStrings = (): void => {
const textNodes = getAllTextNodes(document.body);
for (const node of textNodes) {
const textNodeLength = node.textContent ? node.textContent.length : 0;
if (node.textContent === null) {
return;
}
if (node.parentElement instanceof Element) {
if (node.parentElement.dataset.originalText === undefined) {

Make it into a bookmarklet. It removes everything around the markdown article and opens the print dialog.

Pure ESM package

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.
