Learn Claude Code
Master Claude Code
A structured learning path from understanding context windows to building automated systems. Each lesson takes 1-2 minutes.
Most people use Claude Code like a magic box: throw code in, hope for good output. That approach hits a wall fast.
The difference between frustrating sessions and productive ones isn't the model—it's understanding how to work with it. Context windows, token limits, prompting strategies—these aren't advanced topics. They're the basics that nobody teaches.
This series covers what you need to know, in order. Start with Basics to understand the fundamentals, then move to Practical for real-world techniques.
Why This Series Is Short
Long articles feel authoritative.
That's a mental shortcut: length = depth = value.
(This is called Effort Heuristic and Authority Bias—we tend to trust things that look like they took more work.)
Content farms know this. SEO rewards it.
But it's a trick, not quality.
If you use LLMs, this probably sounds familiar:
- Attention is limited (context windows exist)
- More input ≠ better output
- Passing only what's needed usually wins
Same goes for readers.
So we applied context-window thinking to writing:
- Each article: 1–2 min
- Total: under 30 min
- Density over volume
We don't pad for authority.
We respect your attention.
