The current git dirty state (refrain from automatically read all the modified files right away unless filename(s) are explicitly mentioned) is to implement the requirements described in the file reference/$1.

Don't do anything until I tell you to. I will tell you next.

This is what is next:

Executive Summary

This guide documents how to use Factory's Droid CLI with your Claude Code Max subscription (OAuth authentication) instead of pay-per-token API keys. The solution leverages CLIProxyAPI as a transparent authentication proxy that converts API key requests from Factory CLI into OAuth-authenticated requests for Anthropic's API.

Architecture Overview

Factory CLI → [Anthropic Format + API Key] → CLIProxyAPI → [Anthropic Format + OAuth] → Anthropic API

A hands-on, comprehensive guide for migrating from XCTest to Swift Testing and mastering the new framework. This playbook integrates the latest patterns and best practices from WWDC 2024 and official Apple documentation to make your tests more powerful, expressive, and maintainable.

1. Migration & Tooling Baseline

Notes

MCP servers enabled: Brave Search, Fetch, Puppeteer (optional).
Recommended way to use it: create a project "Deep Research" and add the prompt as custom instructions.
Recommended model: Sonnet 4 with Thinking. Sonnet vs Opus does not make much difference from experience.
(As of the time of writing,) Do not enable Claude's built-in web search feature!
- I've compared the two versions and the quality difference is significant.
- It seems that the built-in system prompt that gets enabled, is terrible for deep research. A few examples: It explicitly limits Claude to only running one or a few searches in most cases; it contains numerous instructions regarding never quoting directly,

	//Proper way to implement error types. Implement `errorDescription`, not `localizedDescription` and the global handler `getErrorMessage(error: Error)` is easy to implement, not need a stupid switch case
	//Key is implement `errorDescription` instead of `localizedDescription` and must not implement `localizedDescription` at all

	struct E1: LocalizedError {
	var errorDescription: String? {
	return "E1's errorDescription"
