The SaaS Prompt Stack — The 15 Claude Code Prompts Behind a Live App With 2,000+ Registered Users

The companion to the Facebook post. bulkinfographics.com — an AI infographic generator with 2,000+ registered users — was vibe coded in one week with Claude Code, and this stack is the exact prompt used at every stage of that build, in the order they were run. THE 15 STAGES: (01) Write the PRD before any code, (02) Create CLAUDE.md so the agent learns your repo's real rules, (03) Plan Mode first — approve 20 lines of plan instead of reviewing 500 lines of diff, (04) The UI brief, (05) Design the database with credits that can never go negative, (06) Auth that holds server-side, (07) The core generation engine with a job state machine and automatic refunds on failure, (08) Bulk ZIP download, (09) Stripe credit packs — webhook-verified, idempotent, with the double-delivery test, (10) The admin dashboard that returns 404 (not 403) to strangers, (11) Debug an error fast — reproduce before fixing, (12) The hostile security pass before anyone else gets the link, (13) One end-to-end test of the exact money path, (14) Clean up + small commits, (15) The ship-it launch checklist. Every prompt is copy-paste ready with [swap tokens] for your own product, plus the run-order guide explaining why documents-before-code is what keeps vibe-coded apps from collapsing at feature three.
