Claude Code, Cursor & Replit App Rescue: From AI Spaghetti to Production-Ready
Aquarel rescues Claude Code, Cursor, and Replit applications stuck in prompt regression loops, 3,000-line monolithic files, and broken Supabase/Stripe integrations. Principal Engineer Dositej Grbović untangles circular dependencies, secures authentication and billing, and installs CLAUDE.md, AGENTS.md, and .cursorrules guardrails in a fixed-scope 1–2 week Rescue Sprint starting at $1,000–$1,500.
Symptom → Root Cause → Surgical Fix Table (Claude Code / Claude, Cursor IDE, Replit Agent)
| What You Experience | Why the AI Agent / App Is Stuck | Aquarel's Surgical Engineering Fix |
|---|---|---|
| Prompting for a small UI tweak breaks Stripe checkout or login | Business logic, database queries, and UI state are coupled inside a single 2,500+ line component exceeding clean context boundaries. | Extract isolated domain modules + freeze auth/billing behind protected service layers and regression tests. |
| Claude Code or Cursor invents duplicate API routes and conflicting DB tables | No repository-level architecture contract (CLAUDE.md / AGENTS.md) telling the agent where schemas and services live. | Consolidate schema migrations and author strict multi-tier CLAUDE.md + .cursorrules guardrails. |
| Works in Replit/local dev, crashes or leaks secrets on production deploy | Hardcoded environment keys, client-bundled server imports, and missing CI build verification. | Separate client/server bundles, rotate & vault env secrets, and configure staging-first deployment checks. |
| AI coding sessions burn hours of tokens repeating the same circular TypeScript or build error | Inconsistent tsconfig module resolution, untyped API payloads, and Hallucinated helper imports across directories. | Establish a single shared Zod/TypeScript domain schema and enforce pre-commit typecheck + build verification gates. |
What Happens in Your Free 48h Codebase Audit vs. Your Fixed-Scope Rescue Sprint
What I Check in Your Free 48h Codebase Audit
- 1. God-file & circular dependency map across your repo
- 2. Supabase RLS policy audit & leaked API key scan
- 3. Stripe webhook idempotency & state sync verification
- 4. 10–15 min plain-English Loom walkthrough + fixed sprint quote
Your "Vibe-Safe Handover" Deliverables
- 1. Clean, modularized production codebase shipped via isolated PRs
- 2. Hardened Auth, RLS, and Stripe billing with automated tests
- 3. Custom CLAUDE.md, AGENTS.md & .cursorrules locked into repo
- 4. Post-sprint Loom training showing how to keep prompting safely
Stop the AI Prompt Death Spiral & Lock In a Vibe-Safe Architecture
Claude Code and Cursor are extraordinary multipliers when guided by senior engineering boundaries. I refactor your monolithic AI files into clean domain modules, harden your auth and billing layers, and install production CLAUDE.md and AGENTS.md contracts so every future prompt ships safely.
What Makes a Repository “Vibe-Safe”?
An unguarded AI codebase fails because the coding agent has no architectural memory between sessions. During your Rescue Sprint, I decompose monolithic files into strict feature slices, isolate Supabase RLS and Stripe webhook logic behind frozen service directories, and commit tailored CLAUDE.md, AGENTS.md, and .cursorrules files so your AI assistant respects production boundaries automatically.

Frequently Asked Questions
Why do Claude Code, Cursor, and Replit start breaking existing features after 80% completion? +
Without explicit module boundaries and repository instruction files (CLAUDE.md, AGENTS.md, .cursorrules), AI agents append new state and database queries into the nearest large file. Once a file crosses 1,500–3,000 lines, context drift causes edits in one section to corrupt unrelated auth or billing logic.
What is included in your CLAUDE.md and AGENTS.md Vibe-Safe Handover? +
I author custom repository instruction files tailored to your exact directory structure: marking auth, RLS migrations, and Stripe webhook handlers as frozen boundaries, enforcing maximum file lengths (250 lines), and providing pre-commit verification commands.
Do you work directly with repositories exported from Replit Agent or Claude Artifacts? +
Yes. Whether your codebase lives in Replit, a local Cursor project, or a GitHub repo managed with Claude Code CLI, I audit and stabilize it into a clean, deployable production pipeline.
How do we start, and what does it cost? +
Book a free 20-minute Triage Call or submit your broken app brief on /triage. After signing a mutual NDA, I deliver a complimentary 48-hour Codebase Audit ($0) and a fixed-price Rescue Sprint quote (starting at $1,000–$1,500+).
Can my team or I keep using Claude Code and Cursor daily after the rescue sprint? +
Yes—that is the entire goal of the Vibe-Safe Handover. By splitting 3,000-line god-components into focused 150–250 line domain files and locking in CLAUDE.md, AGENTS.md, and .cursorrules guardrails, Claude Code and Cursor become dramatically faster and stop regressing production.
