The Problem +Before analyzing data or training machine learning models, cleaning raw data is always the first and most critical step. Identifying null/missing values, duplicates, out-of-range numerical fields, formatting syntax problems (e.g. invalid emails or dates), and status casing inconsistencies is usually done manually with custom Python/Pandas scripts. This can be time-consuming, repetitive, and inaccessible to non-technical users who just want a quick audit of their files. + +## 2. The Approach +We built an AI-powered data quality audit agent using Next.js and the Lamatic API. +- **Workflow:** The user loads or pastes a dataset (CSV) and provides optional instructions (e.g. "Focus on validating emails and ignore columns without names"). +- **Agent Action:** The LLM-backed agent scans the dataset row-by-row, identifying anomalies, missing information, schema mismatches, and duplicated records. +- **Interactive UI:** The Next.js frontend previews the CSV as an interactive table, triggers the Server Action to invoke the Lamatic flow, and renders the detailed audit report side-by-side using markdown. + +## 3. The Result +An instantly usable web tool to run automated health checks on dataset CSVs. Teams receive a clear, prioritized checklist of data clean-up items, complete with column-specific summaries, issues categorized by severity (High, Medium, Low), and actionable cleaning steps to feed into their ETL scripts. + +--- + +## AgentKit Collection (1 flow) + +This AgentKit contains 1 flow: +- **Data Quality Agent** (`flows/data-quality-agent.ts`) + +--- + +## Prerequisites +* **Node.js** (v18 or higher recommended) +* **npm** or **pnpm** package manager +* A valid **Lamatic API Key**, **Project ID**, and **API URL/Endpoint** + +--- + +## Setup Instructions + +1. **Initialize the App Directory** + ```bash + cd apps + npm install + ``` + +2. **Configure Environment Variables** + Create a local env file: + ```bash + cp .env.example .env.local + ``` + Open `.env.local` and add your Lamatic credentials: + ```env + LAMATIC_API_KEY=your_api_key_here + LAMATIC_PROJECT_ID=your_project_id_here + LAMATIC_ENDPOINT=https://your-endpoint.lamatic.dev + DATA_QUALITY_AGENT=your_deployed_flow_id_here + ``` + +3. **Start the Development Server** + ```bash + npm run dev + ``` + The application will be available at `http://localhost:3000`. + +--- + +## Programmatic Usage Example + +The Next.js frontend calls the Lamatic flow via Next.js Server Actions: + +```typescript +import { analyzeDatasetQuality } from "@/actions/orchestrate"; + +const checkData = async () => { + const csvContent = `id,name,email,age +1,John Doe,john@example.com,28 +2,Jane Smith,,thirty-four +1,John Doe,john@example.com,28`; + + const result = await analyzeDatasetQuality(csvContent, "Check for schema issues and duplicates."); + + if (result.success) { + console.log("Analysis Report:", result.data); + } +}; +``` diff --git a/kits/dq-issue-detector/agent.md b/kits/dq-issue-detector/agent.md new file mode 100644 index 000000000..3205d255d --- /dev/null +++ b/kits/dq-issue-detector/agent.md @@ -0,0 +1,22 @@ +# Data Quality Issue Detector + +You are a data quality assistant. + +Your job is to analyze uploaded tabular data and identify: +- missing values +- duplicate rows +- invalid formats +- outliers +- inconsistent categories +- suspicious values +- data type mismatches + +Return: +1.
