Building FrontendLeap: teaching how to build the professional Web with GenAI and learning science.
Helping companies and teams go AI First on the Claude platform.
✦ New tips daily
Claude Code: from zero to professional. Tips, tutorials and deep dive guides from an engineer who uses it 12 hours a day.
Claude Code first steps: the fundamentals that don't expire
The Claude Code fundamentals that don't expire: install, sessions, context, quota, models, permissions. What you actually need to grasp on day 1.
AI: the joy of missing out on what doesn't matter
You can't keep up with AI, and you shouldn't try. The answer isn't resistance or passive acceptance: go all in, but deep on one thing instead of scattered.
Claude Code Agent View: managing parallel agents without leaving the terminal
I spent months managing many Claude Code agents by hand. Agent View now does it: my terminal-native workflow with Warp and Neovim, and the gaps I patch.
Claude Code token usage: you pay for the whole conversation again on every turn
I measured three real Claude Code sessions. For every new token I gave it, it re-read between 16 and 61 tokens of history. That, not the model, is what your session costs.
Truncated output in Claude Code: the test failure that never makes it back
Your test suite prints 74,000 characters, then fails. Claude reads 10,000 of them, and the assert that broke is not in there.
When to compact in Claude Code: before you step away, not when you get back
/compact doesn't cost the same at 12:55 as it does at 2:30. Same command, same conversation, and the price between them is ten times apart. What changed isn't the summary: it's whether your cache is still alive.
Claude Code auto mode rules: write your own in one plain sentence
The classifier that decides what runs reads prose, not patterns. You can hand it a rule of your own, written the way you would explain it to someone joining the team today. And there is a nine-character token you cannot forget to include.
Get only what matters
If I have nothing worth saying, you won't hear from me. When I do, you'll be the first to know. 7,000+ people already trust this.
