AI coding agents can scaffold a SaaS in 48 hours and still ship the same launch bugs: unsigned Stripe webhooks, unauthenticated server actions, unprotected AI routes, and permissive database rules. This kit scans 12 launch vectors, produces a readiness score and a remediation report, then gives your agent a step-by-step skill to fix every finding.
A zero-dependency pre-flight scanner and AI agent skill that audits 12 production launch vectors in AI-built Next.js and Node applications.
Indie SaaS founders, developers, and agencies launching apps built with Cursor, Claude Code, or Antigravity.
Static analysis checks Stripe webhook verification, billing idempotency, server-action auth, rate limits, secret leakage, CORS, RLS, and six other launch blockers.
Audits 12 launch vectors in under 3 minutes and outputs a 0-100 readiness score with a file-by-file remediation plan.
Why this architecture wins
Swipe to compare ↔| Without this skill (Manual & Flawed) | With this skill (Deterministic & Gated) |
|---|---|
| Without this skill ✕ Stripe webhooks accept unsigned payloads, so anyone can spoof a subscription. | With this skill ✓ Signature verification and idempotency checks are enforced before billing code runs. |
| Without this skill ✕ AI routes are public and unbounded, so one scraper can burn the monthly OpenAI budget. | With this skill ✓ Sliding-window rate limits and auth checks protect every costly endpoint. |
| Without this skill ✕ A launch checklist lives in the team and is skipped under deadline pressure. | With this skill ✓ A deterministic 12-vector scan that blocks the release until the score is green. |
