Could you build this?
Partial CLI scaffolding is straightforward, but building a production-grade, graph-aware monorepo build tool requires deep Cargo internals knowledge, graph theory for dependency cycles, and complex process orchestration.
What it would actually take: The tool must parse `Cargo.lock` and `Cargo.toml` files into a directed acyclic graph (DAG) of workspace dependencies, compute topological sorting, calculate content hashes for incremental build caching, and safely parallelize build executions. The engineering complexity lies in edge-case handling across Cargo features, target architecture differences, and workspace inheritance without introducing race conditions.
