Harmonist is an agent orchestration library that enforces protocol compliance at the mechanical level — meaning agents cannot drift off-spec at runtime because the protocol constraints are baked in structurally, not checked after the fact. The claim of 186 prebuilt agents with zero runtime dependencies is the headline worth verifying: no hidden pip installs, no cloud calls, just a portable binary you can drop into a CI pipeline or an air-gapped environment. That is genuinely rare. Most orchestration frameworks assume you will tolerate a dependency tree the size of a small country. The differentiator here is the mechanical enforcement angle — if your multi-agent system keeps going rogue in ways that are hard to debug, a framework that physically cannot express invalid states is worth an afternoon. Reservation: 186 agents sounds impressive until you check whether the ones you need are actually in there. Scan the agent list before committing. -> Best for: AI engineer building reliable multi-agent pipelines for production SaaS
