🧠 Ultimate LLM Codebase Brain Dump Prompt

This prompt is designed for GPT-5, Claude Opus 4.1, Cursor, Claude Code, and cursor-agent to perform a deep, structured analysis of any codebase without pasting the entire repo into chat.

It guides the LLM to:

Browse and discover the codebase using built-in repo tools
Read only the necessary files in intelligent order
Analyze the system at high, mid, and low levels
Identify features, their business purposes, how they work, and how they interact
Output a complete master knowledge document inside codebase-analysis-docs/

	// 1. Go to https://auth.quicknode.com/signup
	// 2. Spin up ethereum, sepolia, or polygon endpoint and add Token/NFT RPC API v2 add-on
	// 3. npm/yarn install @quicknode/sdk in typescript or javascript project
	// 4. Copy and paste code in project and replace endpointUrl and wallet value below
	// 5. profit!

	import Core from "@quicknode/sdk/core";

	(async () => {
	const core = new Core({

	# create a new organization $MYORG

	org = Organization.find_by_name($MYORG)

	hosts = []
	50000.times { hosts << { name: SecureRandom.uuid, organization_id: org.id } }
	host_ids = ::Host::Managed.import(hosts, validate: false).ids

	facets = host_ids.map { \|id\| { host_id: id } }
	facet_ids = Katello::Host::SubscriptionFacet.import(facets, validate: false).ids

	pushd .
	FILES=$(find test -type f -path "$1"\|tr '\n' ' ')
	echo $FILES
	bundle exec ruby -Itest $FILES
	popd

	./test_args.sh "one two" three
	with $*
	["one", "two", "three"]
	with "$@"
	["one two", "three"]

	This is a basic example of using SOCKS.

	From the computer you want to browse on you'll make an ssh connection to the computer you want to browse from.
	In this example it'll be my laptop connecting to my desktop.

	Run: ssh -D <port, I use 10000> <user>@<hostname of desktop>

	Now, in a browser you don't normally use (I'm using firefox), go to network proxy.
