# ingress-migration-advisor Skill Invoked by Zeus pipeline `*ingress-migration-advisor`. This skill sits **upstream** of the three migration skills (`nginx-to-traefik`, `gateway-api-migration`, `nginx-to-gateway`).

The model's job is to invoke them and weave their output into the report — not to re-derive scoring or decision logic in natural language. ## Activation Triggered explicitly b
