The Pattern Re-Selection Test: Which Design Patterns AI Makes Optional

The patterns you apply most carefully may be the ones you need least - and the instinct to keep them feels exactly like good engineering discipline from the inside. There is a three-class test that predicts whether any pattern you currently treat as standard practice is optional or load-bearing at AI speed, and the answer is almost never what the instinct says. In this video: • How to distinguish coordination-over-time patterns from essential-complexity and comprehension-and-safe-change patterns using a single diagnostic question • Why agentic AI tools shift the binding constraint from team coordination across months to one person staying in control of code written faster than they can read it • Which class of patterns becomes optional as team size and elapsed time shrink toward a single session, and which become more important • How hard-fail contracts caught a real schema drift incident that no coordination process would have surfaced • A concrete sorting test you can apply this week to any pattern your team currently treats as standard practice CHAPTERS: CHAPTERS: 01:07 The Pattern Re-Selection Test 03:04 Pattern Re-Selection in Practice 05:49 Reselection Test 08:48 What You Keep and What You Let Go CONNECT: JanisExplains Architecture: browse the channel for more on architectural discipline under changing delivery conditions Comments: share your experience with the sorting question below ABOUT: Janis is a solution architect who works at the intersection of software design discipline and AI-assisted delivery. This video comes directly from working through a real migration project with agentic coding tools and having to sort, under pressure, which patterns were load-bearing and which were habit. The Pattern Re-Selection Test is the result of that experience, not a theoretical framework built in advance.
