# 🔗 AI Handoff — Projects & Agent Workspace
**Live at:** [https://app.ai-handoff.work](https://app.ai-handoff.work)
**Repo:** [https://github.com/stateofshit/url-shortener](https://github.com/stateofshit/url-shortener)
**Built:** August 12, 2026
* * *
## What This Covers
### 1. URL Shortener (Production App)
A **production-ready URL shortener** with **live click analytics**, deployed entirely on **Cloudflare's edge infrastructure**. No accounts, no databases to manage, no servers to maintain. Just paste a long URL, get a short one, and watch the clicks roll in.
📄 See below for full URL Shortener documentation.
### 2. Assistant Workspace (Agent Project)
An **AI agent starter** built with Cloudflare Agents SDK + TypeScript, living at:
```
/home/user/03-projects/assistant-workspace/
```
Copied from `.agents/skills/agents-sdk/my-agent/`. Purpose-built for autonomous agent behavior using the Cloudflare Workers platform.
#### Quick Start
```bash
cd /home/user/03-projects/assistant-workspace
npx wrangler dev # local dev
npx wrangler deploy # production
```

## 🛠️ Tech Stack (URL Shortener)
| Layer | Technology | Purpose |
| --- | --- | --- |
| **Edge Runtime** | Cloudflare Workers | URL shortening, redirects, API endpoints |
| **Static Sites** | Cloudflare Pages | Dashboard + React app deployment |
| **Database** | Cloudflare D1 (SQLite) | Store URLs, click counts, click timestamps |
| **Frontend (Dashboard)** | Vanilla HTML/CSS/JS | Lightweight, fast, no build step |
| **Frontend (React App)** | React 19 + Vite 6 | Modern SPA with same features |
| **CI/CD** | GitHub Actions | Auto-deploy on `git push master` |
| **Custom Domains** | Cloudflare DNS | `*.ai-handoff.work` |
**Agent Workspace uses:** Cloudflare Workers + Agents SDK + TypeScript + Vitest
* * *
## 🌐 Custom Domains (URL Shortener)
All domains point to Cloudflare infrastructure and are **proxied** (CDN + security enabled):
| Domain | Target | Status |
| --- | --- | --- |
| `shit.ai-handoff.work` | Worker API | ✅ Live (200) |
| `dash.ai-handoff.work` | Dashboard (Pages `shrtlink`) | ✅ Live (200) |
| `app.ai-handoff.work` | React App (Pages `shrtlink-app`) | ✅ Live (200) |
**Why custom domains?**
* Professional URLs (not `workers.dev` or `pages.dev`)
* SSL certificates auto-provisioned by Cloudflare
* CDN caching at the edge
* DDoS protection via Cloudflare
* * *
## ✨ Features (URL Shortener)
### 1. URL Shortening
* Paste any `http://` or `https://` URL
* Get a 6-character short code (e.g., `f5RHkl`)
* Short URL: `https://shit.ai-handoff.work/f5RHkl`
* **Strict validation**: rejects `javascript:`, `ftp://`, etc.
* **Dedupe**: shortening the same URL twice returns the existing code
### 2. Live Dashboard
* **Total links count** (real-time from D1)
* **Total clicks count** (sum of all link clicks)
* **Table of all links** with:
* Short URL (clickable)
* Destination URL (truncated if >60 chars)
* Click count (badge)
* 14-day trend sparkline (SVG bar chart)
* Creation date
* Copy button (⎘ → ✓ with clipboard API)
* **Auto-refresh** every 15 seconds
### 3. Click Analytics
* **Per-click tracking**: every redirect logs a timestamp to `clicks` table
* **Daily buckets**: `/api/trends/:code` returns `{day, n}` for last 14 days
* **Sparkline visualization**: inline SVG bar chart per link
* **Zero data loss**: historical clicks preserved even if URL is deleted
### 4. Developer Experience
* **Auto-deploy**: push to `master` → GitHub Actions → Cloudflare
* **Local dev**: `npm run dev` (Vite) + `wrangler dev` (Worker)
* **Type-safe**: D1 queries via Wrangler bindings
* **Testable**: Playwright E2E tests in `/tmp/*.mjs`
* * *

## 🗄️ Database Schema (URL Shortener - D1)
### `urls` table
```sql
CREATE TABLE urls (
id INTEGER PRIMARY KEY AUTOINCREMENT,
code TEXT NOT NULL UNIQUE, -- 6-char short code
url TEXT NOT NULL, -- original URL
clicks INTEGER NOT NULL DEFAULT 0, -- running total
created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);
```
### `clicks` table (migration 002)
```sql
CREATE TABLE clicks (
id INTEGER PRIMARY KEY AUTOINCREMENT,
code TEXT NOT NULL,
clicked_at DATETIME DEFAULT CURRENT_TIMESTAMP,
FOREIGN KEY (code) REFERENCES urls(code)
);
CREATE INDEX idx_clicks_code ON clicks(code, clicked_at);
```
**Why two tables?**
* `urls.clicks` = fast counter for the dashboard badge
* `clicks` table = per-click history for trend charts
* * *
## 🔌 API Endpoints (URL Shortener)
All endpoints on `https://shit.ai-handoff.work`:
### `POST /api/shorten`
**Request:**
```json
{ "url": "https://example.com/very/long/path" }
```
**Response (200):**
```json
{
"shortUrl": "https://shit.ai-handoff.work/f5RHkl",
"code": "f5RHkl",
"dedupe": false
}
```
**Errors:**
* `400` — invalid URL, missing `url` field
* `500` — internal error
### `GET /api/links`
**Response (200):**
```json
{
"links": [
{
"code": "f5RHkl",
"url": "https://example.com/long/path",
"clicks": 42,
"created_at": "2026-08-12T03:00:00Z"
}
]
}
```
### `GET /api/trends/:code`
**Response (200):**
```json
{
"code": "f5RHkl",
"daily": [
{ "day": "2026-08-11", "n": 3 },
{ "day": "2026-08-12", "n": 4 }
]
}
```
### `GET /{code}` (redirect)
**Behavior:**
* 301 Moved Permanently → original URL
* Increments `urls.clicks` + logs to `clicks` table
* CORS headers for cross-origin requests
* * *
## 🚀 Deployment
### Manual Deploy (URL Shortener)
```bash
# Worker
cd wrangler-api && npx wrangler deploy
# Dashboard (Pages)
cd dashboard && npx wrangler pages deploy ./ --project-name=shrtlink
# React app (Pages)
npx wrangler pages deploy ./dist --project-name=shrtlink-app
```
### Auto-Deploy (GitHub Actions)
```yaml
# Triggered on: git push origin master
# Steps:
# 1. Build Vite app (npm run build)
# 2. Deploy Worker (npx wrangler deploy)
# 3. Deploy Dashboard (npx wrangler pages deploy)
# 4. Deploy React app (npx wrangler pages deploy)
```
**Secrets required:**
* `CLOUDFLARE_API_TOKEN` — Cloudflare API token with Pages + Workers permissions
* `CLOUDFLARE_ACCOUNT_ID` — Cloudflare account ID
### Agent Workspace Deploy
```bash
cd /home/user/03-projects/assistant-workspace
npx wrangler deploy
```
* * *
## 🧪 Testing (URL Shortener)
### Local Development
```bash
# Terminal 1: Worker (localhost:8787)
cd wrangler-api && npx wrangler dev
# Terminal 2: Vite dev server (localhost:5173)
npm run dev
# Terminal 3: Dashboard (localhost:3000)
cd dashboard && npx wrangler pages dev ./
```
### E2E Tests (Playwright)
```bash
# Test dashboard features
node /tmp/dash-features.mjs
# Test copy button + trends
node /tmp/copy-test.mjs

node /tmp/custom-e2e.mjs
```
### Agent Workspace Tests
```bash
cd /home/user/03-projects/assistant-workspace
npx vitest
```
* * *
## 🔒 Security (URL Shortener)
* **Strict URL validation**: only `http:` and `https:` protocols allowed
* **CORS**: `Access-Control-Allow-Origin: *` (public API)
* **Dedupe**: prevents duplicate rows for same URL
* **Collision check**: 6-char codes from 62^6 = ~56B combinations
* **SSL**: auto-provisioned by Cloudflare for all custom domains
* **DDoS protection**: Cloudflare edge network
* * *

## 🎯 How to Use
### As a User (URL Shortener)
1. Go to [**https://app.ai-handoff.work**](https://app.ai-handoff.work) or [**https://dash.ai-handoff.work**](https://dash.ai-handoff.work)
2. Paste a long URL into the input field
3. Click **Shorten**
4. Copy the short URL (⎘ button) or click to open it
5. Share it — when people click it, you'll see the click count increase in real-time
### As a Developer (URL Shortener)
1. Clone the repo: `git clone https://github.com/stateofshit/url-shortener`
2. Set up Cloudflare credentials in `.env` (see `.env.example`)
3. Run locally: `npm run dev` + `cd wrangler-api && npx wrangler dev`
4. Deploy: `git push origin master` (auto-deploys via GitHub Actions)
### As a Developer (Agent Workspace)
1. Workspace lives at: `/home/user/03-projects/assistant-workspace/`

## Key Design Decisions (URL Shortener)
### Why Cloudflare?
* **Edge runtime**: Workers execute at the edge (closest to user)
* **Free tier**: 100K requests/day on Workers, 10K on D1
* **Zero config**: No servers, no scaling, no DevOps
* **Built-in SSL**: Automatic HTTPS for custom domains
### Why D1 (SQLite) instead of KV?
* **SQL queries**: need `GROUP BY`, `ORDER BY`, `JOIN` for analytics
* **Relational**: `clicks` table references `urls` table
* **Cost**: D1 is cheaper than Vectorize for this use case
### Why two frontends?
* **Dashboard** (vanilla): lightweight, fast, no build step
* **React app** (Vite): modern SPA, same features, different UI
* **Proof of concept**: shows both approaches work on Cloudflare
### Why 6-character codes?
* **Short**: `f5RHkl` is memorable
* **Collision-resistant**: 62^6 = 56 billion combinations
* **URL-friendly**: no special characters, no encoding needed
* * *
## 🚧 Known Limitations (URL Shortener)
1. **No user accounts**: anyone with the link can see the dashboard
2. **No custom codes**: codes are randomly generated (no `bit.ly`-style custom slugs)
3. **No link expiration**: links never expire (can add TTL later)
4. **No QR codes**: short URLs are text only (can add QR generation)
5. **No mobile app**: web-only (can add PWA later)
* * *
## 🔮 Future Enhancements
### High Priority (URL Shortener)
- [ ] **Cloudflare Access**: lock `dash.ai-handoff.work` behind login
- [ ] **Custom codes**: allow users to set their own short URL
- [ ] **Link groups**: organize links into campaigns
- [ ] **Export data**: download click analytics as CSV/JSON
### Medium Priority (URL Shortener)
- [ ] **QR codes**: generate QR for each short URL
- [ ] **UTM tracking**: append `?utm_source=twitter` to destination
- [ ] **Link expiration**: set TTL
- [ ] **Click geo**: log country/region per click
### Low Priority (URL Shortener)
- [ ] **Mobile PWA**: installable app with offline support
- [ ] **Browser extension**: right-click → "Shorten this URL"
- [ ] **API keys**: rate-limit per user
- [ ] **Webhooks**: notify on new click

## 💡 Lessons Learned (URL Shortener)
1. **Custom domains need DNS records**: Cloudflare Pages doesn't auto-create CNAME for all subdomains — had to manually add `app → shrtlink-app.pages.dev`
2. **D1 migrations are idempotent**: `CREATE TABLE IF NOT EXISTS` is safe to run multiple times
3. **Click logging is cheap**: D1 is SQLite, so logging every click is fine
4. **Sparklines are easy**: inline SVG with `<rect>` elements, no chart library needed
5. **GitHub Actions secrets are mandatory**: workflow fails silently if secrets are missing
6. **Wrangler CLI is powerful**: `npx wrangler pages deploy` works from any directory
## 💡 Lessons Learned (Agent Workspace)
1. **Agent skills stored in `.agents/skills/`** — the canonical source for agent templates
2. **Working copies go in `03-projects/`** — keeps active projects organized alongside other work
3. **Sync when relevant** — changes to upstream agent skills should be reflected in the working copy
* * *
