Init Project - NowStack Mobile

<strict_order>

1. Verify repo/remotes/worktree and Convex setup.
2. Collect one product brief or PRD. Do not run a long questionnaire if the user already gave the idea.
3. Update product context in AGENTS.md and shared config in site-config.ts, then mirror title, slug, bundleId, product ids, and auth.trustedOrigins into convex/siteConfig.ts.
4. Update visible product copy across web-app/ and mobile-app/, including onboarding images in mobile-app/app/onboarding/content.ts and the product id in mobile-app/App.storekit. 4b. Apply branding colors in mobile-app/lib/theme.ts (the single source of truth — every mobile color resolves from there). Ask whether the app wants dual theme (light + dark, ships with a switcher) or a single theme (e.g. dark-only). For single-theme apps, follow the Mono Theme procedure in references/theming.md so the switcher is removed and only one scheme is maintained — never hand-edit scattered hex.
5. Configure backend runtime env in Convex only; never commit secrets. At minimum set RESEND_API_KEY, EMAIL_FROM, BETTER_AUTH_SECRET, SITE_URL (sign-in is broken without them).
6. If the user plans store builds, run cd mobile-app && eas init and copy the project id into site-config.ts > easProjectId; set prod Convex URLs in mobile-app/eas.json.
7. Validate changed surfaces with npm run check-setup plus the build checks, and summarize remaining manual steps from docs/production-checklist.md. </strict_order>

<config_targets> Read these before editing config or branding:

sed -n '1,240p' site-config.ts
sed -n '1,220p' AGENTS.md
rg -n "NowStack|nowts|boilerplate|TODO|SaaS" web-app mobile-app convex docs site-config.ts package.json

Update only values grounded in the product brief. Do not invent legal company, domain, pricing, store ids, or OAuth credentials. </config_targets>

<env_groups> Ask by service group, not one variable at a time:

• Base/Auth: SITE_URL, BETTER_AUTH_SECRET, trusted origins, OAuth client ids/secrets.
• Email: RESEND_API_KEY, sender/contact values.
• Payments: Stripe for web/Android, Apple IAP metadata for iOS, matching site-config.ts.
• Files/R2: target names used by convex/storage/r2.ts, normally R2_ENDPOINT, R2_ACCESS_KEY_ID, R2_SECRET_ACCESS_KEY, R2_BUCKET_NAME, R2_PUBLIC_URL.

Set server-side runtime values in Convex:

npx convex env set KEY "value"
npx convex env list

</env_groups>

npm run check-setup

Then run only the checks that match touched surfaces:

npx convex dev --once
cd web-app && npm run typecheck
cd web-app && npm run build
cd mobile-app && npx tsc --noEmit
cd mobile-app && npm run lint

<stop_gates> Stop and ask when:

• GitHub/Convex authentication requires a browser/login prompt.
• Product brief is missing or too vague to update config.
• Secrets or live payment/store operations are required.
• The worktree contains unrelated changes that would be staged/committed. </stop_gates>
