Could you build this?
No Operating a fast structural AST grep search across vast numbers of public GitHub repositories requires massive distributed indexing infrastructure, AST caching, and high-throughput query execution.
What it would actually take: Requires a distributed pipeline continuously cloning and parsing billions of lines of code into ASTs using tree-sitter or ast-grep engines across varied programming languages. The system must store and index structural graph representations or inverted n-gram AST indices, backed by a large distributed search cluster capable of sub-second structural traversal over terabytes of syntax trees. This requires specialized distributed systems expertise, massive cloud compute/storage budgets, and deep knowledge of compiler IR and code search architectures.
