AI coding tools are incredible. But I noticed something — they ship code fast, skip the rules, and nobody catches it until it's already in production. That's exactly what GuardDuo is built to fix. The Problem We're in the age of vibe-coding. You describe what you want, the AI builds it, it works — and you ship it. But "works" and "correct" are two very different things. Imagine asking an AI to build a login form. It works perfectly. But under the hood it has hardcoded API keys, no input validation, missing aria-labels , and it's using fetch directly instead of your project's apiClient wrapper. Your Issue said none of that was allowed. Nobody caught it. That's the vibe-coding trap — and it's happening on every team using AI-assisted development right now. What is GuardDuo GuardDuo is a GitLab Duo Agent skill that acts as your AI guardian. Instead of just reviewing code in isolation, it cross-references your code changes against the actual intent of the linked GitLab Issue — using the Orbit Knowledge Graph , which is essentially the brain that knows your project's rules, requirements, and success criteria. In plain terms: GuardDuo reads what the Issue asked for , reads what the code actually does , and tells you exactly where they don't match. It audits across three dimensions: 🔐 Security — hardcoded secrets, SQL injection, missing input validation ♿ Accessibility — missing alt text, aria-labels , poor color contrast 📐 Standards — deviations from your project's established patterns and conventions And when it finds a problem, it doesn't just flag it — it fixes it. How It Works Just open GitLab Duo Chat or GitLab Agent Platform(on your choice of IDE) -> choose the agent as GuardDuo and type: Audit issue #[issue no.] — GuardDuo pulls the Issue context from Orbit, analyzes the code, and returns a structured report Fix issue #[issue no.] — GuardDuo generates a corrected implementation that satisfies all requirements Or paste any code snippet directly and ask it to audit o

When a platform started with total developer autonomy, teams felt overwhelmed and ended up solving the same problems in completely different ways. The company shifted to enablement over support, working together with teams intensively, and helping teams feel confident and capable, turning the right way into being the easiest way.

I built InvoiceAI an AI powered invoice generator that lets you describe what you want to invoice in plain English and get a fully formatted invoice in seconds, complete with PDF download and a real payment link. Here's how I built it for the #H0Hackathon. The Problem Freelancers and small businesses waste time manually creating invoices. You know what you did, who you did it for, and how much it costs you shouldn't have to fill out a form to capture that. The Stack - Vercel v0 — scaffolded the entire UI in one prompt Next.js 16 — framework Groq (Llama 3.3 70B) — AI natural language to invoice fields AWS DynamoDB — stores every generated invoice Paystack — generates real payment links jsPDF — client-side PDF generation Vercel — deployment How It Works User types: "50 hours of mobile app development at $80/hr for TechLagos Ltd, 7.5% VAT" Groq parses the text and extracts structured invoice data Live preview updates instantly User downloads PDF — invoice is saved to DynamoDB automatically One click generates a real Paystack payment link to send to the client Building the UI with v0 I used Vercel v0 to scaffold the entire UI in one prompt. It generated a production-ready Next.js component with a split-panel layout form on the left, live invoice preview on the right. I just had to wire up the AI and database logic. Connecting AWS DynamoDB Using the AWS SDK v3, I connected DynamoDB directly from Next.js server actions. Every time a user downloads an invoice, it's saved to DynamoDB with the client details, line items, tax rate, and timestamp. This gives the app a real data foundation that scales from day one. await dynamo . send ( new PutCommand ({ TableName : ' invoices ' , Item : { invoiceId : data . invoiceNumber , clientName : data . clientName , clientEmail : data . clientEmail , items : data . items , createdAt : new Date (). toISOString (), }, })) The Result AI generates invoice from plain English in under 2 seconds Real PDF download (no print dialog) Real Paystack
