What you can do with Claude Code

The shift isn't just about writing code faster — it's about the type of problem you can tackle.

**Why it matters:** Tasks that previously required hours of manual effort — writing comprehensive test suites, migrating to a new framework, translating an entire codebase — become single prompts. Claude handles the tedious execution while you focus on design and architecture decisions.

With Claude Code you can:

🤖 Automate tedious tasks: write tests, resolve merge conflicts, update dependencies, write release notes

🔨 Build features and fix bugs by describing them in natural language

🌿 Create commits and pull requests directly from chat

🔌 Connect external tools via MCP (Jira, Slack, PostgreSQL, Figma...)

⚙️ Customize with CLAUDE.md, Skills and Hooks

🤝 Run parallel agent teams for complex tasks

"Write tests for the auth module, run them, and fix any failures" — Claude Code executes all three steps, iterating until all tests pass.

1# Monitor logs and get alerts
2tail -f app.log | claude -p "Slack me if you see any anomalies"
3
4# Automate translation in CI
5claude -p "translate new strings into French and raise a PR"
6
7# Bulk security review
8git diff main --name-only | claude -p "review these files for security issues"

1# MCP integration — connect your tools:
2claude mcp add github    # Issues, PRs, code search
3claude mcp add postgres  # Query databases directly
4claude mcp add slack     # Send messages and alerts
5
6# Then use them naturally:
7> "check Sentry for the top 5 errors this week"
8> "find all users in postgres who signed up today"

What task in your workflow do you repeat every week and wish you could automate? Write it down — we'll tackle it in Module 11.
