Debugging & Code Review with Claude Code
Only 3.1% of developers say they highly trust the accuracy of AI-generated code (Stack Overflow Developer Survey 2025), and 66% are frustrated by solutions that are "almost right, but not quite". Accepting everything without checking and rejecting AI entirely are both dangerous extremes. This guide teaches the professional middle ground: calibrated trust. Learn to detect hallucinations in code, review AI output with a dedicated checklist, debug with Claude Code as a tool (not an oracle), and decide when to regenerate and when to edit. The central mental model ("Managing an Intern") changes how you supervise AI code. 8 modules, 43 capsules, and a project where you perform a complete professional code review of a codebase with real problems.

What you'll be able to do
- Why only 3% trust AI code and how to calibrate your own trust
- The "Managing an Intern" mental model for supervising AI code
- Circuit Breaker and Trust Calibration as complementary frameworks
- Detect subtle hallucinations: fake imports, invented APIs, fabricated logic
- A professional code review checklist for AI-generated code
- Common error patterns: naming, edge cases, security holes
- Systematic debugging with Claude Code: log analysis, stack traces
- Subagents (the Explore agent) to investigate codebases
- A decision framework: when to regenerate and when to edit by hand
- Project: a complete professional code review of a codebase with problems
What you need to bring
Requirements and materials
- [Claude Code Foundations](https://nieva.team/en/courses/claude-code-foundations-guide) and [Prompt Engineering with Claude Code](https://nieva.team/en/courses/prompt-engineering-with-claude-code-guide) (or equivalent experience with Claude Code)
- Recommended: [Testing with Claude Code](https://nieva.team/en/courses/testing-with-claude-code-guide), because this guide verifies with pytest
- Experience writing your own code (so you have a basis for comparison)
- Familiarity with basic debugging (print statements, logs)
- Claude Code installed and configured

What people usually ask
No limit. It's a free guide: come in whenever you like, as often as you like.
No. Modules run from easier to harder, but you can jump to the one you need. Progress is saved per lesson.
Whatever is needed is listed under “What you need to bring”, above. If nothing is listed there, you can start from zero.
In the WhatsApp group, and every two weeks there's a live with an instructor where questions get worked through.
Yes. When you finish every lesson you get a statement of completion. Pass the guide's certification exam and it becomes a certificate, with a verifiable code you can share on LinkedIn.
