Claude Code Tool Guide: Enterprise Setup and Practical Workflows

TL;DR

• Install via pip install claude-code or IDE plugins (VS Code, JetBrains).
• Core commands: claude explain, claude generate --type=test, claude review --pr.
• Enterprise note: Free tier includes 1MB context window (Anthropic Console).

1. Installation and Authentication

Install the CLI

Option A: pip (Recommended)

pip install claude-code

Verify installation:

claude-code --version
# Expected output matches latest in [Anthropic Changelog](https://docs.anthropic.com/en/docs/claude-code/changelog)

Option B: IDE Plugins

• VS Code: Official Extension
• JetBrains: Available via JetBrains Blog

Authenticate

1. Generate an API key in the Anthropic Console.
2. Run:

   claude-code auth login
   

   Copy
3. Verify:

   claude-code auth status
   # Expected: "Authenticated as <your-email> (Plan: Free/Pro)"
   

   Copy

2. Configuration for Teams

Global Settings (~/.claude/config.toml)

[default]
model = "claude-3-sonnet"  # Default per [Anthropic Blog](https://www.anthropic.com/blog/claude-code-aster)
temperature = 0.3
max_tokens = 4096          # Free tier limit

[editor]
line_length = 88
tab_size = 4

Project-Specific Setup

Initialize a repository:

cd your-repo
claude-code init

Creates:

.claude/
├── ignore          # Pattern-matching (e.g., `**/secrets/`)
├── prompts/        # Custom templates
└── rules.toml      # Project rules

Coding Standards (CLAUDE.md)

Example for a Python/Django project:

# Project: Enterprise Inventory System
- **Stack**: Django 4.2, PostgreSQL 15
- **Requirements**:
  - All models must include `created_at`/`updated_at`
  - Use `django-environ` for config
- **Test Coverage**: Minimum 85%

3. Core Workflows for Development Teams

Code Generation

Code Review Automation

# For pull requests
claude-code review --pr=https://github.com/yourorg/repo/pull/42

# For local changes
claude-code review --diff="git diff main..feature-branch"

Sample output (Anthropic Blog):

🔍 Analyzed 3 files (420 lines)
✅ src/auth.py: No critical issues
⚠️ src/utils.py:
  - [Medium] Timing attack in `compare_secrets()` (line 88)
📝 Suggested fixes: [unified diff]

Architecture Diagrams

claude-code explain --file=src/system.py --output=diagram --format=mermaid

Generates:

• Class relationships
• Data flow
• External dependencies

4. CI/CD Integration

GitHub Actions Example

name: Claude Code Review
on: [pull_request]

jobs:
  review:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: pip install claude-code
      - run: claude-code review --pr=${{ github.event.pull_request.html_url }}
        env:
          CLAUDE_API_KEY: ${{ secrets.CLAUDE_API_KEY }}

Local Pre-Commit Hook

#!/bin/sh
exec claude-code review --staged --fail-on=high

5. Enterprise Considerations

Security Controls

1. API Key Restrictions:

   claude-code auth configure --restrict-to=repo:yourorg/*,pr:read-only
   

   Copy
2. Sensitive Code Exclusion (.claude/ignore):

   **/secrets/
   **/config/prod/
   

   Copy

Cost Optimization

Monitor usage:

claude-code usage --format=json > usage-report.json

Next Steps for Your Team

1. Pilot setup:

   claude-code init --sample-config > ~/.claude/config.toml
   

   Copy
2. Integrate with one workflow:

   claude-code test --framework=pytest >> test-report.md
   

   Copy
