Could you build this?

Partial While a prototype agent executor is easy to build, designing a novel domain-specific task specification language (HopSpec) and a dedicated JIT execution engine for agents requires non-trivial language and runtime engineering.

What it would actually take: Building HOP 3.0 requires designing an AST, parser, and runtime for the HopSpec language, coupled with an execution engine (HopJIT) that handles dynamic DAG scheduling, streaming LLM outputs, state caching, and speculative branching. The stack would typically be written in Rust or C++/Go for runtime performance, combined with LLM API orchestration layer. The hard part is building robust execution semantics, debugging primitives, and low-latency state synchronization across stochastic agent actions.
