- Impeccable is a publicly available AI design assistant skill in the pbakaus/impeccable repository on GitHub. According to the original article, when installed in an AI tool such as Claude Code, it first asks for product information and sets a work order, which keeps the AI from falling back to a common average design.
- The author made the same landing page request in four ways. The number of automated check findings was 5 to 8 items, so the difference was small. On the author's judgment of whether the design still works after changing the product name, only the method that asked for product information first and then built the page was hard to reuse for other products.
- Run times were about 5 minutes for default Claude Code, about 15 minutes for the method that had existing results critiqued and revised, and about 20 minutes for the method that built from scratch with Impeccable. The author recorded these with a script in a Windows and WSL 2 environment with Claude Code v2.1.287, so these figures are values measured in that environment.
O: This method is worth trying when a designer who had AI draft a landing page wants to check whether the same structure still works after changing only the product name and target customers.
X: The comparison with the original is an experiment based on conditions and evaluation criteria set by one author, so before generalizing a result where the number of inspection findings was similar, check it again in your own environment.
