Plan and execute incremental product isolation migrations to a facade plus contract layer in PostHog, following the Visual review architecture. Use when a product still exposes internals (models/logic/views) across boundaries and needs a safe, multi-PR migration toward contracts.py + facade/api.py + presentation separation.
This skill does not declare a tool allowlist. The agent host applies whatever default tools are available at runtime.
