Common Use Cases

Use Case	Description
Automated Code Review	Review code quality on PR submission
Test Generation	Generate tests based on code changes
Documentation Updates	Auto-update docs after code changes
Code Translation	Translate comments or documentation
Security Scanning	Detect potential security issues

Headless Mode Overview

In CI/CD, Claude Code runs in “headless” mode without interactive input. Use -p for prompts and --allowedTools to control available tools:

# Basic usage
claude -p "Review this PR for code quality" --allowedTools "Read,Glob,Grep"

# JSON output
claude -p "Analyze code and provide suggestions" --output-format json

Security Considerations

Use read-only tools: Limit to read-only operations in CI/CD
Isolate network: Run in isolated environment
Audit logs: Record all Claude operations
Secrets management: Pass API keys through secure secrets
