You might want to know that Gambit is an open source Scheme implementation that has been around a very long time.

We ran into similar reliability issues while building GTWY. What surprised us was that most failures weren’t about model quality, but about agents being allowed to run too long without clear boundaries.
What helped was treating agents less like “always-on brains” and more like short-lived executors. Each step had an explicit goal, explicit inputs, and a defined end. Once the step finished, the agent stopped and context was rebuilt deliberately.
Harnesses like this feel important because they shift the problem from “make the model smarter” to “make the system more predictable.” In our experience, reliability came more from reducing degrees of freedom than from adding intelligence.

This is an interesting direction for agent frameworks. What stood out to me is the shift from simple tool orchestration to agents that can reason, call other agents, and self-manage workflows. That’s something we’ve been thinking about a lot while building SalesPlay — especially around how autonomous sales agents need clear evaluation, guardrails, and accountability to actually be useful in real GTM teams. The built-in grading/evaluation angle here feels like a practical step toward making agents less brittle and more production-ready. Curious to see how this evolves in real-world use cases.
