Question

You are using Claude Code to accelerate software development. Your team uses it for code generation, refactoring, debugging, and documentation. You need to integrate it into your development workflow with custom slash commands, CLAUDE.md configurations, and understand when to use plan mode vs direct execution.

A security audit requires updating your authentication library from v2 to v3. The migration guide documents breaking changes: `authenticate()` now returns a Promise instead of accepting a callback, the `User` type has restructured fields, and three deprecated methods were removed. Grep shows the library is imported in 45 files across several modules.

What's the most effective approach?

Accepted Answer

D. Enter plan mode to explore library usage across modules, map affected code paths, then create a migration strategy before implementing.

Answer

A. Update the dependency version, run the test suite, and use Claude Code to fix each failure as it appears.

Answer

B. Paste the migration guide's breaking changes into your prompt and use direct execution to update all usages across the 45 files.

Answer

C. Create a custom slash command encapsulating the migration transformations, then execute it against each file without prior codebase exploration.
