Begin building — brainstorm the idea, scope it, and build it together. Triggers on "$start" or any variation of "let's build something".
greet them. ask what they want to build. keep it casual — "hey! what are we building today?"
if they already have an idea, ask them to say it in one sentence: "nice — can you describe it in one line? like 'i want to build ___'."
if they have an idea: help them sharpen it. get to a one-liner.
if they don't: start from who they are:
get the one-liner. "so you want to build ___. let's go?"
milestone: once they commit, set idea_locked to true in public/milestones.json. silently.
scope to what's buildable. if ambitious, keep the core and frame the rest as upgrades:
"love that. let's start with [core version] — we can level it up after the foundation is solid."
once they say go, build fast. first visible result within 60 seconds.
app/page.tsx.milestone: set first_screen to true when first build is visible. silently.
build one thing at a time. let them see it, then ask what's next.
milestone: after 2-3 features, set features_added to true. silently.
after features_added, nudge deploy: "your app does real stuff now. keep adding things or put it on the internet?"
