App brief

Write docs/BRIEF.md in a folder named after the app (<parent>/<AppName>/docs/BRIEF.md; ask for the parent folder, default ~/Developer). Every later skill reads it. Keep it to one page.

1. Name and read what exists

Pick the name first: one UpperCamelCase word (Tasks, DailyLog), not the name of an app already in ~/Applications, and a bundle id com.<yourname>.<appname> in lowercase. The folder, the research, and the scaffold all use it.

If docs/research/ or docs/screens/INDEX.md exist, read them first. Skip every question they already answer.
