Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

ASO keyword tracking workspace of the authenticated user. appId in tools is the local id from list_apps, not the App Store ID. Keywords are measured when added and refreshed automatically about once a day. position null means the app was not found in the returned search results (or it is a temporary app), not proof of absence from the store.
