Plan Input Validation

Agent skill
1 skill

Audit every trust boundary for unvalidated input, injection, and forged-request gaps, then produce a phased hardening plan. Use when the user says "validate my inputs", "is my app injection-safe", "check my forms", "XSS", "dangerouslySetInnerHTML", "my Stripe webhook", "can someone forge requests", or is hardening before launch. AI code has happy-path bias: missing Zod, dangerouslySetInnerHTML without DOMPurify, webhook signature gaps (empty or unchecked signing secrets), raw-body signature mistakes, missing idempotency. Stack-aware for Supabase, Stripe, Next.js. Plan only until each phase is approved. Pairs with plan-rls-audit, plan-security-audit, audit-fe-api. Do NOT use for row access (plan-rls-audit) or secrets (plan-secrets-audit).
