Could you build this?
Partial A VS Code fork or bespoke editor UI paired with an LLM for SQL/Python is achievable, but robust AST parsing, data lineage graph engines, and live query execution sandboxes require deeper systems expertise.
What it would actually take: The architecture involves an Electron/Monaco-based editor or VS Code extension combined with a local LSP server that constructs an in-memory SQL/Python DAG using tools like SQLGlot or DuckDB. The hard part is building reliable semantic diffing and automated data validation test loops across multi-stage transformation graphs without corrupting execution states. A solo vibe coder can build an LLM SQL assistant UI, but reliable interactive lineage execution requires significant compiler and database systems expertise.
