Strict skill for reproducing ML models. Use for: (1) Reproducing paper algorithms, (2) Porting open-source models, (3) Integrating multiple algorithms into one agent, (4) Adapting a model to downstream tasks. Core rule: engineering code may change (adapters, I/O, logging, config), but the algorithm must stay untouched.
Keywords: reproduce, reimplement, port, migrate, adapt, integration.
