+# Antigravity Automated Issue-Resolution Workflow
+
+This guide details the automated pipeline for listening to, processing, resolving, and verifying GitHub issues using the Antigravity agentic system.
+
+---
+
+## 1. Workflow Architecture
+
+```mermaid
+sequenceDiagram
+    participant GH as GitHub Webhook / Action
+    participant OR as Orchestrator Agent
+    participant IP as Implementation Planner Agent
+    participant DEV as Developer Agent
+    participant CI as CI Build & Browser Verifier
+    
+    GH->>OR: Webhook: Issue Labeled ('agent-resolve')
+    Note over OR: Parses issue details &<br/>checks config
+    OR->>OR: Git Branch Checkout (feature/issue-N)
+    OR->>IP: Spawns Planner Agent with prompt
+    IP->>IP: Researches codebase & generates plan
+    IP-->>OR: Returns plan
+    OR->>DEV: Invokes Developer Agent to write code
+    DEV->>DEV: Modifies files & implements feature
+    DEV-->>OR: Code complete
+    OR->>CI: Runs verification (npm run build & test)
+    CI-->>OR: Compilation / Test Success
+    OR->>GH: Git Commit & Push. Auto-creates Pull Request
+    Note over GH: GitHub Action checks pass.<br/>Human reviews & merges PR.
+```
+
+---
+
+## 2. Webhook Payload Specifications
+When an issue is labeled (e.g. `agent-resolve`, `enhancement`, `bug`), GitHub triggers a webhook with the following JSON structure sent to the Orchestrator endpoint:
+
+```json
+{
+  "action": "labeled",
+  "issue": {
+    "number": 12,
+    "title": "IMPLEMENT RISK MANAGEMENT UPGRADE: #ISSUE-005 - Kelly Allocation",
+    "body": "Detailed objective description...",
+    "state": "open",
+    "labels": [
+      {
+        "name": "agent-resolve"
+      }
+    ]
+  },
+  "repository": {
+    "full_name": "jannr/investment-sandbox",
+    "html_url": "https://github.com/jannr/investment-sandbox"
+  },
+  "sender": {
+    "login": "jannr"
+  }
+}
+```
+
+---
+
+## 3. Step-by-Step Execution Lifecycle
+
+### Step 3.1: Parsing and Routing
+The Orchestrator Agent parses the webhook payload, maps labels using `github-agent-config.json`, and triggers the workflow.
+
+### Step 3.2: Branching Strategy
+The system automatically creates a branch:
+- For enhancements: `feature/issue-{issue_number}`
+- For bugs: `bugfix/issue-{issue_number}`
+
+### Step 3.3: Planning & Coding
+1. The Orchestrator launches an **Implementation Planner Agent** to search the codebase and write an `implementation_plan.md` draft.
+2. Once the plan is approved (autonomously or by a maintainer), the **Developer Agent** modifies the target code files.
+
+### Step 3.4: Automated Verification
+Before pushing changes, the Orchestrator runs:
+- `npm run build` to verify Next.js/TypeScript compilations.
+- Virtual browser tests (Playwright/Puppeteer stubs) to simulate UI button interactions, state modifications, and graph renderings.
+
+### Step 3.5: PR Creation and Merge
+1. The agent pushes the branch to remote and creates a PR using the GitHub API:
+   `POST /repos/{owner}/{repo}/pulls`
+2. Once merged by a human, the branch is deleted and the issue is closed.

+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
