Could you build this?
Partial Providing a UI or basic embedding index across repos is straightforward, but maintaining robust cross-repository semantic dependency graphs and coherent persistent agent memory requires sophisticated indexing.
What it would actually take: The platform needs a multi-repo ingestion pipeline parsing git commit histories, dependency manifests, and symbol definition/reference graphs (LSIF/SCIP). It combines a vector database with a relational or property graph database (like Neo4j) to map cross-repo dependencies and maintain stateful memory for LLM context windows. Ensuring low query latency and preventing context poisoning across large software organizations requires distributed systems and static analysis engineering.
