+# Code Review Agent
+
+An agentic Next.js starter kit that performs AI-powered code reviews on GitHub Pull Requests using Lamatic Flows. Enter any public GitHub PR and get a structured analysis of bugs, security vulnerabilities, and style issues in seconds.
+
+## Live Demo
+
+[agent-kit-stk.vercel.app](https://agent-kit-stk.vercel.app)
+
+---
+
+## What It Does
+
+The agent takes three inputs — GitHub owner, repository, and PR number — then runs a multi-step agentic flow:
+
+1. **Fetches** the PR diff from the GitHub REST API
+2. **Extracts** the raw patch content from all changed files
+3. **Analyzes bugs** — null pointer risks, logic errors, runtime failures
+4. **Analyzes security** — hardcoded secrets, injection risks, insecure dependencies
+5. **Analyzes style** — naming conventions, complexity, readability
+6. **Synthesizes** a concise overall summary of PR quality
+
+Results are returned as structured JSON and rendered in a premium dark-themed UI with severity-aware triage cards.
+
+---
+
+## Tech Stack
+
+| Layer | Technology |
+|---|---|
+| Frontend | Next.js 16.2.1, React 19 |
+| AI Flow | Lamatic Flows (GraphQL API) |
+| LLM | Groq — `llama-3.3-70b-versatile` |
+| GitHub Data | GitHub REST API |
+| Deployment | Vercel |
+
+---
+
+## Prerequisites
+
+- Node.js 18+
+- A [Lamatic](https://lamatic.ai) account with the Code Review Agent flow deployed
+- A [Groq](https://console.groq.com) API key (free)
+- A [GitHub](https://github.com) account (for public PR access)
+
+---
+
+## Environment Variables
+
+Create a `.env` file in the kit root:
+
+---
+
+## Lamatic Flow Setup
+
+This kit requires a Lamatic flow with the following node structure:
+
+```text
+API Request Trigger (owner, repo, pr_number)
+       ↓
+Code Node — extract diff from GitHub API response
+       ↓
+GitHub API Node — GET /repos/{owner}/{repo}/pulls/{pr_number}/files
+       ↓
+Generate JSON — Bug Analysis
+       ↓
+Generate JSON — Security Scan
+       ↓
+Generate JSON — Style Check
+       ↓
+Generate JSON — Final Merge (summary)
+       ↓
+API Response
+```
+
+Import the exported flow from the `flows/` directory into your Lamatic project, then update the `workflowId` in `app/api/review/route.ts` with your deployed flow ID.
+
+---
+
+## Running Locally
+
+```bash
+# 1. Install dependencies
+cd kits/agentic/code-review
+npm install
+
+# 2. Set up environment variables
+cp .env.example .env
+# Fill in your LAMATIC_API_KEY
+
+# 3. Start the dev server
+npm run dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) in your browser.
+
+---
+
+## Usage
+
+1. Enter the GitHub **owner** (e.g. `fmtlib`)
+2. Enter the **repository** name (e.g. `fmt`)
+3. Enter the **PR number** (e.g. `4660`)
+4. Click **Review PR**
+
+The agent will fetch the diff and return:
+
+- **Summary** — a concise 2-3 sentence overview of PR quality
+- **Bugs** — logic errors and runtime risks with severity levels (High / Medium / Low)
+- **Security** — vulnerability findings with severity levels
+- **Style** — readability and code quality suggestions
