Real-World Use Cases

Refactor Old Payment Module

Developer

3 days

An e-commerce startup has an old payment module that was written three years ago, making it hard to maintain and lacking tests.

Problem

The dev team consists of only two people, making it difficult to understand and safely rewrite the entire module while still needing to develop new features.

Solution

Use Claude Code to analyze the entire module, propose a step-by-step refactoring plan, and automatically write a test suite before changing the code.

Completed the refactoring of the payment module in 3 days instead of the planned 3 weeks
Test coverage increased from 0% to 70%
No production errors occurred after deployment
Documented the entire payment processing workflow

Migrate Project from JavaScript to TypeScript

Technical Manager

4 days

A software development agency has an internal project with 15,000 lines of JavaScript code that needs to be converted to TypeScript to reduce runtime errors.

Problem

Manually converting each file is time-consuming and easy to overlook types, while the team does not want to stop developing features to work on this.

Solution

Use Claude Code to automatically convert each module to TypeScript, add type definitions, and fix any compilation errors that arise.

Completed migration of the entire project in 4 working days
Identified and fixed 23 potential errors thanks to type checking
Did not interrupt the schedule for developing new features
Reduced runtime bugs by 30% after 1 month of monitoring

Pros

Understands the context of the entire codebase, not just the open file, allowing for more accurate multi-file error correction
Can execute terminal commands, run tests, and perform git commits as requested, reducing manual effort
Integrates well with the review process through git diff, making it easier to control changes before applying
Handles complex multi-step tasks like large refactors, library migrations, and batch test writing effectively
Supports multiple popular programming languages and frameworks
Can be customized via project configuration file (CLAUDE.md) to adhere to team-specific conventions

Cons

Runs in the terminal, lacking a graphical interface, so those unfamiliar with command line may take time to adapt
Cost per token can increase rapidly with large codebases or long working sessions
Requires careful permission management for command execution, with risks if destructive commands are run unchecked
Occasionally suggests changes outside the scope of the request, requiring thorough review before acceptance
Effectiveness depends on the quality of the request description and provided context
Relies on internet connectivity and the availability of Anthropic's service
