# Claude Code, Cursor & Replit App Rescue: From AI Spaghetti to Production-Ready

Canonical URL: https://aquarel.io/services/claude-cursor-replit-rescue
Category: Platform & Stack Spoke
Stack: Claude Code / Claude, Cursor IDE, Replit Agent, CLAUDE.md & AGENTS.md, Supabase & Next.js, Stripe Billing
Price Anchor: Starts at $1,000–$1,500+ | Typical Turnaround: 1–2 Weeks (Free 48h Initial Codebase Audit)

> 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-to-Fix Diagnostic Matrix

| What You Experience (Founder Symptom) | Root Technical Cause | 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. |

## Phase 1: Free 48-Hour Initial Codebase Audit Checklist ($0)

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

## Phase 2: Fixed-Scope Rescue Sprint & 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

## Technical Architecture & Rescue Approach

## 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.
