Use this skill when API behavior, route docs, Cassandra integration, or ML fallback behavior is unclear or broken and the FastAPI contract must be corrected and documented.
Use this skill when the user asks to audit data and notebook artifacts, classify what is runtime-required vs regenerable/archive/removable, or clean repository footprint safely.
Use this skill when docs and implementation may have drift and you need to align README, documents, notebook descriptions, and actual code behavior.
Use this skill when the user asks to regenerate Casablanca simulation artifacts end-to-end (zone maps, H3 lookup, warped trajectories, trajectory index, and NYC to Casa synthetic trips) with correct git policy.
Use this skill when Kafka -> Flink -> Cassandra flow is stale, delayed, missing records, or behavior is inconsistent and you need structured runtime plus code-path debugging.
