5-second summary

Learn how to use Anthropic's Claude for writing and file management, setup Claude Projects, and install Claude Code for automated command-line developer workflows.

What it means

What happened
Authors, developers, and tech publications including Ruben Hassid, Steve Sewell, Daniel Nest, and nitinfab published guides on how to use Claude, Claude Projects, and Claude Code. These guides detail workflows ranging from personal AI brain setups to command-line coding automation.
Why it matters
Claude Code marks a shift from basic chat assistants to agentic tools that can read files, execute linting commands, and edit local code repositories directly. Mastering both the basic interface and command-line execution helps users automate writing and coding tasks.
What you can do
Start by using Claude Projects to store your documents and persistent rules in a central context hub. Next, install Claude Code in your terminal to allow the AI to edit files and run terminal commands under your supervision.

According to creator Ruben Hassid, 98.75% of all humans have never tried Anthropic's Claude AI. Yet for power users, developers, and writers, Claude has transformed daily workflows—with Builder.io's Steve Sewell noting that he shifted from using Cursor agents for over a year to living entirely inside Claude Code. Beginners on Reddit have even reached out in panic, asking for foundational guides because their work and future depend on mastering these tools.

This tutorial walks you through setting up Claude, organizing your context using Claude Projects, and configuring Claude Code for active file management and command execution.

Prerequisites and Requirements

Before beginning this walkthrough, ensure you have the following ready:

  • An active account on the Claude platform.
  • Access to a web browser or the Claude Desktop application.
  • A terminal interface (such as VS Code, Xcode, or standard command line) if you intend to install and run Claude Code.
  • Documents, scripts, or notes you plan to upload into your workspace.

Step 1: Accessing the Claude Interface

To begin using Claude for standard tasks such as writing, document analysis, and ideation, open your web browser or launch Claude Desktop. The base platform functions as an interactive assistant capable of analyzing text, editing copy, and answering complex queries.

  • Navigate to the official Claude interface in your web browser or open Claude Desktop.
  • Start a fresh conversation thread for generic queries or quick brainstorming tasks.
  • Input text or attach relevant files, such as PDFs or text documents, to process context in real time.

Step 2: Build Your Personal AI Brain Using Claude Projects

Tech writer nitinfab describes Claude Projects as a personal AI brain. Projects allow you to cluster relevant documents, scripts, and persistent system instructions together so Claude maintains memory and context across multiple chats.

  1. Create a new project: In the Claude interface, navigate to the Projects tab and select the option to create a new project.
  2. Upload core context: Add your reference files, research papers, notes, or code scripts to the project repository. You can upload extensive background material, including large text files or documentation up to 200-page equivalents.
  3. Set global instructions: Add persistent instructions to direct how Claude should respond within this specific project space. Specify your preferred formatting, tone, or operational rules.
  4. Initiate contextual chats: Start new conversations within the project. Claude will automatically reference all uploaded files and custom instructions without requiring you to re-upload them every time.

Step 3: Install and Configure Claude Code

If you need an assistant that can perform active development tasks directly on your machine, you can install Claude Code, an agentic CLI tool described in guides by Daniel Nest on Why Try AI and Steve Sewell on Builder.io.

  1. Open your command line interface: Launch your preferred terminal, such as VS Code's integrated terminal, Xcode, or your operating system's standard terminal application.
  2. Run the installation command: Follow the setup instructions provided by Anthropic in their official support center to install Claude Code into your development environment.
  3. Authenticate your session: Log in when prompted by the CLI to link your terminal session with your account credentials.

Step 4: Execute Agentic Developer Workflows

Unlike standard text chat interfaces, Claude Code is designed to take direct action on your workspace files. When executing tasks, Claude Code will prompt you before modifying your directory structure or executing scripts.

  1. Navigate to your working directory: Open your project folder inside your terminal application.
  2. Issue task requests: Type your prompt into the CLI. For instance, ask Claude Code to inspect your codebase, modify functions, or correct errors.
  3. Grant permissions: By default, Claude Code will display permission requests before taking action on your system. You will see prompts such as:
    • Can I edit this file?
    • Can I run lint?
    Confirm each request to allow Claude Code to edit the requested files or execute command-line linting and testing toolkits.

Step 5: Bypass Approval Prompts (Advanced Workflow)

For high-speed, automated tasks, power users sometimes bypass manual file-by-file authorization checks.

  1. Evaluate security risks: Automatically approving terminal actions gives the agent full authorization to write, edit, and delete local code. Only run automated modes in sandboxed or backed-up environments.
  2. Run the bypass command: To launch Claude Code without permission prompts, run: claude --dangerously-skip-permissions
  3. Monitor automated outputs: Allow the tool to process file edits and terminal commands continuously without stopping to request approval for every modification.

Tips and Pitfalls

  • Keep context structured: When utilizing Claude Projects, keep project files updated and remove obsolete notes so your persistent instructions remain precise.
  • Mind automated actions: Be cautious when executing claude --dangerously-skip-permissions, as it allows Claude Code to execute terminal operations and file revisions automatically without manual review.
  • Integrate with code editors: Claude Code can be run directly alongside code editors such as VS Code or Cursor. While its integration with Windsurf is unconfirmed, reports suggest it probably works within similar extension setups.

Limitations

  • Model tier details: Specific next-generation model designations remain unconfirmed or subject to conflicting reports. While some writer guides cite Claude Opus 4.7, official platform entries discuss potential tiers like Opus 5, Opus 5.5, Fable 5, and Fable 5.1. Treat specific upcoming version listings as unverified until officially confirmed.
  • Terminal access: Claude Code requires command-line access and permission to execute commands; users working strictly within basic mobile or browser interfaces cannot run CLI agent features.
