Transcript

There is one file in Claude Code that controls how smart it actually is. And most people set it up completely wrong. So here are my five tips to build your Claude.md right, build it the right way, step by step. And stick around for no. 5 because it's the one most people skip. No. 1 what even is it? So your Claude.md is essentially just your table of contents for all of your other files. So you might have hundreds of files, but this is the one that Claude reads automatically at the start of every single session. So it's an index that points Claude to everything else that it might need. No. 2 don't write it from scratch. Run /init. This is where people get very overwhelmed, but don't worry, you don't need to write it yourself. Just run the slash command and let AI build it for you. No. 3 treat the starter as a draft. So once you run the slash command, review it and make sure that everything is accurate. So go through it, fix anything that's wrong and make sure you're reviewing it over time if anything changes. No. 4 give Claude a map. So drop in a quick summary as well as a simple folder tree of where all of your important stuff lives. Now Claude will know exactly where to look instead of like digging around blind. No. 5 keep it under 200 lines. So this file loads into every single session, so if it gets too big, Claude actually pays less attention to the stuff that actually matters. Keeping it as lean as possible is always gonna be more productive.
