Real cases from briefing to delivery: redesigns and projects with an AI agent in production, with the prompts used, the decisions and what each stack delivered.
This is where real projects are documented end to end, with the prompts that were used and the decisions taken along the way. The opening case is the redesign of the Instituto +Brasal website, run with Claude Code in two phases: the first analyses the available skills catalog and executes six competing stacks from the same brief; the second redoes the three stacks that had a visual reference once DESIGN.md and the motion guide existed, and shows what changed when the constraint became explicit.
A case on ZUMKAI is not a portfolio piece. It is a record of the process: what the stack actually delivered, where it broke, what it cost in tokens and what would be done differently. Start with the full process, then read the comparison of stacks D, E and F, which only makes sense with the first part as context.
Three redesign stacks with a design reference, redone once DESIGN.md and the motion guide existed: what each got right, what broke and the prompt at each step.
From analyzing the skills catalog to running six competing stacks on the Instituto +Brasal redesign, with every prompt used and what each stack delivered.
