Publishing commits the skill file to a roleplane-skills repo under your GitHub account and opens the index-entry PR as you — attribution is the PR authorship. The registry stores nothing: your token lives only in a short-lived cookie and is discarded after use.
Log in with GitHub first, then fill in the form.
Teams stay authored in your own Workspace. Point at an existing team directory in your repo and the app opens the index-entry PR as you, pinned to the repo's current SHA. Deep validation happens in CI.
