What You Will Learn

  • Use Claude effectively on inherited content.
  • Layer follow-up questions.
  • Verify Claude's explanations.
  • Build an onboarding workflow.
  • Recognize when Claude hallucinates.

Why This Matters

Onboarding to inherited code or content is where most hours are lost. Claude compresses hours of reading into minutes — but only if you verify and layer questions well.

Concept Explained

Claude excels at explaining content: code, documents, research papers. The trick is layered follow-ups that drill into specifics, plus verification against the actual content.

How It Works

Paste content or attach file. Ask Claude to explain. Layer follow-ups for specifics. Verify each explanation against the actual content.

Step-by-Step Tutorial

1. Paste or attach content

Attach file or paste text. Claude reads it.

2. Ask for explanation

'Explain what this does in 3 sentences.'

3. Drill into specifics

'What does the second loop do?' or 'why is null checked twice?'

4. Verify

Read the actual content alongside Claude's explanation. Catch hallucinations.

5. Document

Save verified explanations as comments or notes.

Real-World Example

A new hire inherited a 1500-line legacy module. Pasted into Claude, layered questions, verified each explanation. Built a complete mental model in 90 minutes — work that would have taken a full day.
