Token-aware reasoning workflow with real tools: picks an operating mode to control cost, runs a structured pipeline (decompose → validate → verify → snapshot), and gives Claude Program-of-Thought, RK4/Euler, a code gate, and a safe skill router. Use when: multi-step or high-stakes tasks, real math, precise computation, audits, or the user mentions APEX, PoT, pipeline, or scientific mode.
**v00.33.0**: Ingested from antigravity-awesome-skills community repo

The following phases must be completed in order. Validate at the end of each phase before proceeding.
.env.example created with all required variables✅ Validate: Run npm run build — no TypeScript or lint errors should appear.
🔧 If build fails: Check tsconfig.json paths and that all shadcn/ui peer dependencies are installed.
lib/db.ts✅ Validate: Run a simple db.select().from(users) in a test script — it should return an empty array without throwing.
🔧 If DB connection fails: Verify DATABASE_URL format includes ?sslmode=require for NeonDB/Supabase. Check that the migration has been applied with drizzle-kit push (dev) or drizzle-kit migrate (prod).
✅ Validate: Sign in via OAuth, confirm session user has id and subscriptionStatus. Attempt to access /dashboard without a session — you should be redirected to /login.
🔧 If sign-out loops occur in production: Ensure NEXTAUTH_SECRET is set and consistent across deployments. Add declare module "next-auth" to extend session types if TypeScript errors appear.
✅ Validate: Complete a Stripe test checkout using a 4242 4242 4242 4242 card. Confirm stripeSubscriptionId is written to the DB. Replay the checkout.session.completed webhook event and confirm idempotency (no duplicate DB writes).
🔧 If webhook signature fails: Use stripe listen --forward-to localhost:3000/api/webhooks/stripe locally — never hardcode the raw webhook secret. Verify STRIPE_WEBHOOK_SECRET matches the listener output.
✅ Validate: Run npm run build for a final production build check. Navigate all routes manually and confirm no broken layouts, missing session data, or hydration errors.
For additional guidance, generate the following companion reference files alongside the scaffold:
CUSTOMIZATION.md — Auth providers, database options, ORM alternatives, payment providers, UI themes, and billing models (per-seat, flat-rate, usage-based).PITFALLS.md — Common failure modes: missing NEXTAUTH_SECRET, webhook secret mismatches, Edge runtime conflicts with Drizzle, unextended session types, and migration strategy differences between dev and prod.BEST_PRACTICES.md — Stripe singleton pattern, server actions for form mutations, idempotent webhook handlers, Suspense boundaries for async dashboard data, server-side feature gating via stripeCurrentPeriodEnd, and rate limiting on auth routes with Upstash Redis + @upstash/ratelimit.Manage — Generates complete, production-ready SaaS project boilerplate including authentication, database schemas, billing integration, API routes, and a working dashboard using Next.js 14+
Use this skill when the task requires saas scaffolder capabilities.
If this skill fails to produce the expected output: (1) verify input completeness, (2) retry with more specific context, (3) fall back to the parent workflow without this skill.
