for Claude..

I'm working on this project, but I've faced so many issues that I now want to rewrite the entire project. I'm no longer interested in correcting it, so we should use the old code as a stepping stone for a new version of the project. So 1. I tell all I can about the project 2. I will post the old codes for you to understand fully 3. Then we will rewrite the project into a new one, by first, a. having a full project plan and flow to the deployment level in the next 1 hour. b. implementation and testing in 3hrs. So do you understand? Should I post the project information and the project 31 code files?

the problem is i cannot post the 31 code here due to limit faced here. so should i tell you about the project can you figure it out? agentkonnect/

the info-- AgentKonnect: Nigerian Car Marketplace Platform Core Purpose: To create a seamless, AI-powered car buying/selling experience on WhatsApp that addresses Nigeria's unique market needs while ensuring safety and efficiency. How It's Designed to Operate 1. Conversational Flow Natural Nigerian Context: Understands Pidgin/English mixes ("I wan buy tokunbo Camry for 2m") Recognizes local terms: "tokunbo" (foreign used), "LGA" (local govt area), "Opay" Mid-Flow Flexibility: "I was looking at cars but actually want to sell my Honda" "Stop - show me dashboard instead" 2. Key Features For Buyers: Location-based car searches ("Show Camrys in Lagos") Price filtering ("Cars under ₦3m") Safe contact sharing For Sellers: Step-by-step listing creation Image uploads via WhatsApp Package selection (Free to Premium) Value-Added Services: Price advice ("What's my 2015 Camry worth?") Safety tips Market insights 3. Nigerian Market Specialization Local Knowledge: Knows popular models (Toyota > Mercedes) Understands regional price variations Recognizes payment methods (OPay transfers)

-- Part A. SMART GREETING & INTENT DETECTION a. Logic: Detect any casual/formal greeting in Nigerian English or Pidgin: “How far”, “How you dey”, “Good morning”, “Wetin dey sup”, etc. Respond politely in english with a branded intro. Ask clearly if the user wants to buy or sell a car. b. NLP Memory: Non-Linear Handling: If a user skips greetings (e.g., "I want sell my Toyota"), skip intro and jump to Part B/C. Detect synonyms like “buy”, “get”, “purchase” OR “sell”, “offload”, “market” in non-linear sentences. Smart fallback if intent is unclear: “Are you looking to buy or sell a car today?” ✅ Sample Response:this is perfect return formatResponse( ${greeting}! Welcome to AgentKonnect 🤝\n\n + "We're here to help you buy or sell cars quickly, safely, and easily across Nigeria.\n\n" + "Please reply with:\n" + "1️⃣ Buy a car\n" + "2️⃣ Sell a car\n\n" + "Disclaimer: We connect buyers and sellers but don't handle payments. Stay safe!" ); c. welcome back greeting for paid seller - your suggestion here? Part B. SELLER FLOW a. Smart Flow: Concise intro on how AgentKonnect helps sellers."Great! Let’s list your car. I’ll need this details:" Mandatory fields: 1. Model/Year (e.g., "Toyota Camry 2010") 2. Location: State → LGA → Area (e.g., "Lagos: Ikeja LGA, Allen Ave") 3. Condition: Nigeria used/Foreign used/New 4. Transmission: Automatic/Manual 5. Price (e.g., "₦2.5M") 6.Image: "Upload 3 photos of your car now (one at a time)." (If user sends >3 images: "I’ll use the first 3.") If chat is used to collect data, makee sure all the data is collected the most impoartant -(model/year, budget, and location/ images/number): Immediately offer package options post-details. ✅ Suggested Response After Data Collected: Thanks! Before your car goes live, please choose a listing package: PACKAGE CARS DURATION PRICE QUICK LIST 1 3 days FREE INDIVIDUAL 1 30 days ₦1,000 AGENT STARTER 3 30 days ₦3,000 AGENT PRO 5 30 days ₦4,500 AGENT ELITE 10 30 days ₦8,500 (You can reply with ...) then proced to payment if it's not free Payment Options: "Pay via: (1) Bank Transfer: OPay 812** [AgentKonnect], (2) Payment Link [generate unique link]. Send ‘PAID’ with proof (screenshot/TxID) after payment." Confirmation Logic: Auto-verify if payment link used (webhook integration). If manual transfer: Admin verifies TxID behind scenes → Bot confirms via chat: "Payment verified! Your car is live. Manage it here: [dashboard-link]" If "PAID" but unconfirmed: "Checking payment status... We’ll notify you in 10 mins. Thanks!" After Payment Confirmation: If confirmed: Show them dashboard access. If not confirmed: Send friendly reminder and reconfirmation options. Dashboard Options is only for paid seller (so the data should be stored for about 40days right? ):work with what we have Part C. BUYER FLOW Intent Recognition: Detect buy-synonyms: "buy", "need car", "shop motor", "see vehicles" Detect buyer intent even if phrased indirectly: “Abeg, any car I fit get?” “Looking for something cheap around Enugu.” Non-Linear Handling: If user says "Show me SUVs under ₦3M in Abuja", extract details and proceed. this is the most important information we need to sharch for the buyer car (model/year, budget, and location) If model/year, budget, and location are provided, proceed directly. Else, ask for missing fields. 🛒 Buyer Filters: Car Model + Year (or just Model) Budget Location Optional: Condition (Foreign or Nigerian used) 🔁 Matching Logic: Match top 3–5 cars closest to criteria and if more suggest to see more. Prioritize model/year → location → budget. Provide info clearly. ✅ Example Response: plaintext Thanks! Based on your budget and location, here are a few matches: 1.2.3.4.5. Reply with the number to see pictures Seller contact If they respond with “1”, show: 3 pictures Seller contact with Cautionary note ⚠️ Always inspect the car physically before making full payment. -You’re advised to go with a trusted mechanic. -AgentKonnect only connects buyers and sellers. ⚠️ Pretext for Contact:once they click the contact number to chat Include line: Tell the seller you got this from AgentKonnect ✅. D. Handle general queries like: “How to value my car?” “What’s the best used car under ₦3M?” “Can you help me compare Camry vs Accord?” and others .......*
