+Writing feedback → understand it → update CLAUDE.md

+# Vision
+
+Notes from building things.
+
+## What This Is
+
+A project log. I write down what I'm doing as I do it. Prompts, decisions, dead ends, things that worked.
+
+Sometimes there's audio or video when it's easier to explain that way.
+
+## Why
+
+Two reasons:
+
+1. **For me** — I forget what I did and why. Notes help me pick up where I left off.
+2. **For others** — If you're building something similar, maybe this saves you time.
+
+## Tone
+
+- Casual
+- Concise
+- Direct
+- No fluff
+- No hyperbole
+
+If something sucked, I'll say it sucked. If something worked, I'll say what worked.
+
+## Format
+
+Each project gets a series of notes. Each note covers one session or one phase. Notes include:
+
+- What I was trying to do
+- The prompts I used
+- What happened
+- What I learned
+
+Code snippets, screenshots, audio/video when useful.
+
+## Not a Tutorial
+
+This isn't polished educational content. It's raw notes. Some things will be wrong. Some things will be incomplete. That's fine.
