Adopt — Brownfield Template Adoption

This skill audits an existing project's artifacts for format compliance with the template's skill pipeline, then produces a prioritised migration plan.

This is not /project-stage-detect. /project-stage-detect answers: what exists? /adopt answers: will what exists actually work with the template's skills?

A project can have GDDs, ADRs, and stories — and every format-sensitive skill will still fail silently or produce wrong results if those artifacts are in the wrong internal format.

Output: docs/adoption-plan-[date].md — a persistent, checkable migration plan.
