Decision framework

Apply these three tests to every piece of user-facing output. If a message fails any test, redesign it.

1. The "So What?" Test

Every warning must answer: what should the user do about this?

# Fails — not actionable, user can't do anything
Sub-skill 'my-skill' from 'my-package' overwrites existing skill

# Passes — tells the user exactly what to do
Skipping my-skill — local file exists (not managed by APM). Use 'apm install --force' to overwrite.
