AI Architecture Advisor

The front-door decision skill for "I have problem X — what should I build with?" It owns the choice — which approach fits, when to promote complexity (and when not to), how to transfer knowledge, how to scale — then hands off to the deep skill that owns the depth. It spans the whole modeling space in one place so you can compare options that normally live in separate skills side by side:

tabular GBDT  ·  deep net  ·  Transformer/LLM  ·  RAG  ·  fine-tuning  ·  agents
multimodal/omni  ·  embeddings & retrieval  ·  recsys/ranking  ·  model architecture (dense/MoE/SSM/diffusion)

No theory dumps — decision tables, elimination logic, tradeoffs, and a pointer to the deep skill.
