Show HN: Gambit, an open-source agent harness for building reliable AI agents (github.com)

Gambit, an open-source agent harness, has been introduced to streamline the building of reliable workflows for large language models (LLMs). By allowing developers to create small, typed "decks" with defined inputs and outputs, Gambit addresses common pitfalls in AI development, such as high costs linked to complex context management and difficulties in debugging due to brittle orchestration. Users can run Gambit locally with a simple command, making it accessible for quick testing and iteration. This tool is significant for the AI/ML community as it shifts the focus from traditional, monolithic prompts to modular, manageable components that can be easily tested and debugged. Each deck acts as a self-contained unit with explicit guardrails, enabling better observability and reducing reliance on external logs for debugging. Gambit promotes efficient resource usage by allowing developers to feed models only necessary information for each step and supports interchangeable LLM and compute tasks, laying the groundwork for robust and maintainable AI systems.
