Read the full description
Antaeus is an open-source Go engine and CLI for human-written business policies. Define YAML or JSON rules, validate versioned artifacts, and run named regression cases locally. Semantic evaluators judge conditions; the engine applies configured allow, review, deny, or failure outcomes with inspectable decision records. The local core requires no Antaeus account. Early and pre-v1; semantic evaluator integrations are experimental.

Yes Building a rule engine in Go that parses YAML/JSON policies, evaluates conditions, and runs local test suites is a well-defined software problem that LLMs excel at generating.
