PRAXIS harvests undocumented business rules by simulating developer workflows, then indexes them on the dependency graph

Domain code generation fails on tacit knowledge, the business rules, interface contracts, and operational conventions developers absorb but rarely write down. PRAXIS simulates typical developer workflows inside the target codebase to extract that knowledge, structures it against the code dependency graph, and pushes relevant pieces into context proactively rather than waiting for the agent to search. It beat search-equipped state-of-the-art agents plus experience-based and skill-based alternatives across architectures and models, with gains growing as accumulated experience grows, though the abstract gives no headline numbers.
