"One of the main challenge for me: you build something, but the challenge is after."
Marelys was talking about the part of delivery that teams undercount.
The first build is not the end of the work. It is where the next layer of context starts to matter: deployment details, stack decisions, edge cases, ownership, and the reason the feature was built this way in the first place.
Small changes feel expensive when the team has to rediscover all of that before touching the code. Why did we choose this flow? Which service owns the state? What broke last time? Which ticket had the original constraint? Was this built for one customer or a broader product bet?
Hamster keeps delivery tied back to the Brief, Plan, Tasks, and Blueprint, so the next change starts from what is already true. The context that shaped the first delivery becomes useful again when the team comes back to modify it.
This is where product delivery compounds. Not because nothing changes after launch, but because change has memory.
When a follow-up change appears, start from the Brief or Blueprint, not from a blank prompt. The question is not just "can AI edit this code?" The question is "can AI edit this code with the same context the team used the first time?"
