Running Claude Code isn’t just about opening the terminal and typing the perfect prompt.

(Bookmark this post for later)

There are environment variables that can influence how Claude Code runs, connects to models, and even how its interface behaves.

🧵 Here’s a thread with all of them organized by category: Authentication and API

Configure authentication methods for Claude Code.

These variables control API keys, authorization tokens, and custom headers used when communicating with Anthropic's services or AWS Bedrock.

I analyzed Claude Code's complete system prompt and classified the information into 5 distinct tiers.

(bookmark this to study later)

Every interaction with Claude Code processes information across these 5 layers between your project and the AI model.

🧵 Thread with simple breakdown of each tier: TIER 1 - CRITICAL (Immutable Rules)

These are absolute. Cannot be overridden under any circumstance.

- System Identity & Purpose
- Security Policies (defensive only, refuses malicious code)
- Tool Usage Policy (specialized tools over bash commands)

Think of this as the constitution.

How Claude Code Plugins work 🧵

Plugins work at the Marketplace level, first you install a marketplace, then browse all its available plugins.

Let me show you how to install a marketplace and get your first plugin running 👇 Start by running /plugin in Claude Code
This opens the Plugin Management menu where you can:

- Browse & install plugins
- Manage installed plugins
- Add new marketplaces
- Manage your marketplaces

Introducing Deep Graph MCP for Claude Code 🤩

Claude Code by @AnthropicAI is excellent and arguably one of the best tools for working with code today but...

It has one major limitation, its native code search capabilities don't scale well to large repositories.

By adding Deep Graph MCP, Claude's ability to explore large codebases improves dramatically.

In this thread 🧵 I’ll show you how easy it is to connect this MCP to Claude Code. Start by creating a CodeGPT account and uploading your repository to Code Graph.

Then, get your API key from API Connections

Free Open Source Course on MCP – Built with Knowledge Graphs!

I created a complete course on how to build an MCP Client and MCP Server using the Python SDK.

All structured via knowledge graphs extracted from the repo itself.

Let me show you what’s inside 👇 🧵 1/ Here's a demo of the first project:

A Streamlit MCP Client that connects to a local MCP Server. (SSE)

using only a few lines of code with the MCP Python SDK

🧵 2/

“My project became so big that Claude can’t understand it.”

Many developers face this problem: LLMs struggle with large codebases.

But what if your AI assistant truly understood your entire project?

I’ll show you how to build a knowledge graph of your codebase and use CodeGPT to create an AI Copilot that never forgets context. 🧵👇 Step 1: Connect GitHub to CodeGPT Studio

First, create a free account on CodeGPT Studio

➡️ Go to the Code Graph section.

➡️ Click +Add Connection and select GitHub, GitLab, or Bitbucket.

➡️ Authorize CodeGPT to access your reposcodegpt.co

Introducing DeepSeek R1:1.5b Running Locally in Cursor!

In less than 4 minutes, I set up the DeepSeek R1:1.5b model, download it, and run it locally to seamlessly work with code in Cursor

The video is shown in real-time, with the model impressively running on an Intel Core i5 😱 using Ollama and the CodeGPT extension 👇 First, Install CodeGPT in Cursor:

Llama3 70B as a copilot in VSCode thanks to the integration with Perplexity 🤩

The opensource llama3 70b model released by Meta has already surpassed many private models.

Now you can use it by connecting to @perplexity_ai through its API.

In this thread 🧵 I tell you how to connect the accounts and use it in VSCode 👇 Go to and create an account perplexity.ai

Llama 3 as a Copilot in VSCode 🤩

Let me show you how to connect this amazing model that Meta released today!

Here is a step-by-step tutorial! 🧵 Requirements:

You must have the CodeGPT extension installed in VSCode.

Claude 3 as a Copilot in VSCode is a game changer.

Every day, I program more and more using Claude 3, and it keeps getting better.

Thanks @alexalbert__ and the Anthropic team, for creating such an incredible model 👏👏👏

In this thread🧵 I'll explain the different ways you can connect Claude 3 in VSCode 👇 #1 — Anthropic API Key

Create an account on Anthropic using the following link:

Then go to the “Get API Keys” menu and create a new API Key 🔑 console.anthropic.com
