init-universal-plugin

Creates a plugin, adopts an existing one onto the open standard, or changes what an existing one declares. It is the only skill of the four that writes the canonical plugin.json.

It runs five phases: survey, classify, confirm, apply, verify.

The confirm phase

Adoption turns hand-written vendor manifests into build output, so the skill states the plan and waits for approval before it rewrites anything you authored. Creating a file that does not exist yet needs no approval.

Adoption is lossless by contract

After the build, git diff over the vendor manifest paths should show formatting churn and nothing else. A field that disappeared is a regression.
