💬 claude-code

claude-code is Anthropic's agentic developer CLI tool. It operates as an interactive programming partner directly inside your local terminal, capable of analyzing codebases, editing files, running test suites, committing changes via Git, and managing multi-step development loops.

📊 Tool Datasheet

Metric	Details
Tool Name	claude-code
Category	Terminal Agentic Coding Assistant
Purpose	To act as an autonomous pair-programmer, executing search, edit, build, test, and git operations directly in your terminal.
Developer	Anthropic
License	Commercial / Developer Beta

🛠️ Capabilities

1. Semantic File Operations: Searches files (using ripgrep-style grep/find), reads contents, and writes precise contiguous or non-contiguous multi-line edits.
2. Autonomous Code Builds: Proposes and executes bash build commands, monitors compiler outputs, and corrects compilation errors automatically.
3. Git Integration: Generates commit messages, checks branch statuses, and stages or commits changes.
4. Local Dev Server Check: Spawns and interacts with local dev servers, verifying endpoint health.
5. Interactive Slash Commands: Run commands such as /doctor (health checks), /compact (truncates context history), /search (code base search), and /settings (configure client options).

🧭 Step-by-Step Tutorial & Setup

This tutorial walks you through installing claude-code and executing an automated codebase check.

1. Installation

Install the tool globally using npm or uv:

npm install -g @anthropic-ai/claude-code

2. Authentication & Login

Set your API key variable and login to authorize the CLI:

export ANTHROPIC_API_KEY="your_anthropic_api_key_here"
claude login

3. Running an Interactive Session

Launch the interactive terminal session inside your project workspace:

cd ~/AI_BOOTCAMP
claude

Inside the session, ask the assistant to search the codebase and explain the structure:

claude> List all FastAPI routes in this project and explain their authentication models

4. Direct CLI Flags & Commands

You can also run one-off tasks directly without entering the interactive shell using flags:

### Execute prompt directly
claude -p "Run pytest, inspect why tests on tests/test_auth.py are failing, and apply a fix"

### Run command while bypassing interactive tool execution prompts
claude -p "Audit source directory and compile dependencies" --dangerously-skip-permissions

💡 Sample Ideation to Test

Try these ideas to expand your claude-code workflow:

1. Incremental Spec-Driven Implementation: Initialize a Spec-Kit feature plan, then feed the tasks.md checklist directly into claude-code to implement and test each task sequentially.
2. Automated Pre-Commit QA: Create a shell wrapper that triggers claude-code on staged git changes to perform code simplification, format cleanup, and security checks before allowing a merge.
