WebDesignIter: Giving Front-End Coding Agents 'Design Knowledge' to Survive Repo-Level Iteration

arXiv·medium signal

Front-end repos accumulate change on change with complex cross-file dependencies that single-shot-tuned LLM agents can't track, causing functional regressions and unmaintainable code. WebDesignIter argues the missing piece is design knowledge — architectural principles, module responsibilities, and structural constraints — and co-evolves that knowledge alongside the code for repository-level front-end generation. It targets the durability gap between one-shot UI generation and real, iteratively-maintained front-end codebases.
