Building Feature by Feature
Now for the fun part — building your actual features. The key is to focus on one feature at a time, get it working, then move to the next.
The Build-Test-Iterate Loop
1
Describe the feature
Tell Claude exactly what you want, referencing your spec
2
Test in the browser
Click around, try edge cases, see how it feels
3
Request refinements
"The button should be bigger" or "Add validation for empty input"
✓
Move to next feature
Once it's working, pick the next item from your spec
⚠️ Avoid Feature Creep
Stick to your MVP spec. It's tempting to add "just one more thing" — resist! Ship the core, then iterate.
