Using Claude.ai for Coding Help
Debugging
Paste an error and the relevant code, and ask for the likely cause and a fix.

Using Claude Code for Agentic Tasks
For more involved, multi-step coding work, Claude Code lets you delegate a task directly from the command line, desktop app, or mobile app, rather than manually copying code back and forth from a chat window.
Best Practices Either Way
Always review generated code the same way you'd review a human contributor's changes, ask for tests alongside any generated function, and be specific about your existing code conventions and constraints in your prompt.
