AI coding assistants struggle with multi-repository projects because they lack visibility into API contracts, shared utilities, and cross-repo architectural conventions, leading to integration mismatches and duplicate code. Syncfusion Code Studio addresses this with multi-repo workspaces that let developers open multiple Git repositories side by side in a single environment. Combined with per-repository instruction files (.codestudio/codestudio-instructions.md) that document tech stack, folder structure, API formats, and coding conventions, AI gains the context needed to generate code that fits the whole system. A practical walkthrough covers setting up a frontend+backend workspace, writing effective instruction files, and building a cross-repo bookmark feature. Best practices include keeping instructions specific and concise, updating them as the codebase evolves, and organizing workspaces by development context rather than loading every repo at once.
