Stop seeding the whole system to test one query
When you want to know whether a GET endpoint stays fast with 100k orders, do not drag the whole system into the test. Seed the right data, test through the app, and let telemetry guide the next step.
Skillful, reusable AI workflows from files you own

Boundaries: Where to Draw the Line
Most architectural problems are boundary problems. Knowing where to draw the line, and when to redraw it, is one of the hardest parts of building software systems.
