"Even though you have all these specifications very clear, it's really fast to build something. But the main challenge is really on the specifications."
Marelys put words to the new bottleneck.
AI made implementation faster. It did not magically make product judgment easier. The hard part is still deciding what should exist, why it matters, what constraints shape it, which tradeoffs the team is accepting, and how everyone will know it worked.
Alex described a version of the same delay from the engineering side: the technical design phase alone took a week before a single line of code was written.
That week is not always waste. Sometimes it is where the real product thinking happens. But when the spec process is just forcing people to reconstruct context, negotiate ambiguity in meetings, and format the same understanding into another document, the team is paying the coordination tax before it even starts building.
Hamster helps you move from rough signal to buildable Brief, then from Brief to Plan, Tasks, and Delivery. The Brief is not a giant PRD. It is the artifact that holds enough shared context for humans and AI agents to know what they are building and why.
The spec is done when the team and the agent can answer the same questions: what are we building, who is it for, why this shape, what constraints matter, and what would make us say it shipped?
