✦ 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

Claude Code Agent View: managing parallel agents without leaving the terminal

/cost in Claude Code: stop guessing what broke your cache
Your session drags and eats your limit. You knew it was the cache, and that was where the trail ended. Now Claude Code names the cause.
/skill-doctor in Claude Code: clean out the skills you never use
Every skill you have loaded writes a line into your system prompt on every turn, used or not. `/skill-doctor` puts them in a table with what each one costs, how many times it ran and when. On mine, 24 out of 43 had never run once.
Claude Code effort per model: set it once and never touch it again
If you switch models often you have been moving two dials, the model and the reasoning level. The second one now travels with the first, and your settings.json holds a key you never wrote.
Move Claude Code to a new machine: what to copy from ~/.claude and what to leave behind
Your ~/.claude weighs gigabytes and your own part fits in a megabyte. Copying it whole drags three traps along: the login, the paths and the machine identity.
