[REQUESTED CHANGES]
(no specific request — apply your best judgment)
--- HOW TO RESPOND (READ FIRST) ---
Before writing any code, follow this exact process:
1. **ANALYZE** the widget source code provided above and identify:
a. Which Vibes SDK features it already uses (vibes.save, vibes.load, vibes.shared.join, etc.)
b. Which SDK features would genuinely benefit THIS specific widget — tailored to what it does, not a dump of everything available.
2. **PRESENT A NUMBERED LIST** covering:
- SDK features currently active in this widget
- New SDK features that would concretely improve this widget (be specific: why this widget, what it enables)
3. **WAIT** — do not write any code yet. Reply with your analysis and numbered list, then stop and ask the user which numbered items they want.
4. **IMPLEMENT ONLY** the items the user confirms, plus any explicit change they requested. Do not add unrequested features.
**IMPORTANT — Shared state room names:**
If you add vibes.shared.join(), do NOT use a hardcoded string literal as the room name (e.g. vibes.shared.join("lobby")) unless the user explicitly wants ALL viewers to share one single global state. A hardcoded room name means every person who visits this widget reads and writes the same shared state — it is a global room. For per-user or per-session isolation, derive the room name from a variable (e.g. a user ID, session token, or random value). When in doubt, use vibes.save/vibes.load for per-user persistence instead.
--- VIBES SDK CONTEXT ---
## Vibes SDK Reference
You are building an HTML widget for It Just Vibes (itjustvibes.com). The Vibes SDK is auto-injected — do NOT add a script tag. Just use `window.vibes` (or just `vibes`).
### Setup
Wrap your startup code in `vibes.onReady`:
```js
vibes.onReady(async () => {
const saved = await vibes.load("myKey");
// your widget logic here
});
```
### State (Per-User Persistence)
Every user gets their own isolated state per widget. All methods return Promises.
| Method | Description |
|--------|-------------|
| `await vibes.save(key, value)` | Save JSON-serializable data |
| `await vibes.load(key)` | Load saved data (returns `null` if not found) |
| `await vibes.delete(key)` | Delete a saved key |
| `await vibes.listKeys()` | Get array of all saved key names |
**Key rules:**
- Keys are strings, max 64 characters, alphanumeric + dashes/underscores
- Values must be JSON-serializable (objects, arrays, strings, numbers, booleans)
- Max 100KB per value, 500KB per widget per user, 5MB per user total
- Max 100 keys per widget per user
### Fetch Proxy
Use direct `fetch()` for APIs with permissive CORS headers (`Access-Control-Allow-Origin: *`). Use `vibes.fetch` for APIs without CORS headers (the proxy handles cross-origin requests):
```js
const resp = await vibes.fetch("https://api.example.com/data", {
method: "GET", // GET, POST, PUT, DELETE
headers: {}, // optional headers
body: null, // optional body (string)
timeout: null // optional timeout in ms
});
const data = await resp.json(); // or resp.text()
console.log(resp.status, resp.ok);
```
### API Keys (never put a key in your code)
The widget owner stores keys in **Manage → Secrets**. Never hard-code an API key — anyone can read widget source.
**Server keys** (OpenAI, Stripe secret, etc.): pass the secret's name as `useSecret`. The proxy adds the key to the request; your code never sees it. The owner must also add the API's domain under Allowed Domains.
```js
const resp = await vibes.fetch("https://api.openai.com/v1/models", { useSecret: "OPENAI_KEY" });
```
**Browser keys** (keys built to be public, e.g. a Google Maps JavaScript API key): some libraries need the key in the page. Read it at runtime — it resolves `null` if the owner hasn't set it, so always handle that case:
```js
vibes.onReady(async () => {
const key = typeof vibes.browserKey === "function" ? await vibes.browserKey("GOOGLE_MAPS_BROWSER_KEY") : null;
if (!key) { showSetupMessage(); return; } // e.g. "Owner: add a Browser secret in Manage → Secrets"
loadGoogleMaps(key);
});
```
For website-restricted keys (Google Maps), the owner restricts the key to `https://run.itjustvibes.com/*` and turns on **Manage → Settings → Send origin as referrer**. Browser keys are visible to every viewer; never use `browserKey` for a server key. Forks don't get the owner's keys.
### Multiplayer (Shared State)
Real-time shared state across all users viewing the same widget.
```js
// Join a room (call once at startup)
await vibes.shared.join("lobby", { persistent: true });
// Set shared state (broadcasts to all users)
await vibes.shared.set("score", { player1: 10, player2: 7 });
// Read shared state (synchronous, returns last known value)
const score = vibes.shared.get("score");
// Listen for changes to a specific key
vibes.shared.onChange("score", (newValue) => {
console.log("Score updated:", newValue);
});
// Listen for any shared state change
vibes.shared.onAny((key, value) => {
console.log(key, "changed to", value);
});
// Get number of connected users
const count = await vibes.shared.getUserCount();
// Leave room
vibes.shared.leave();
// Clear all shared state for this room
await vibes.shared.clear();
```
**Shared state options:**
- `{ persistent: true }` — state survives page reloads (stored server-side)
- Default room name is "__default__" if omitted
### Agent-Accessible State (vibes.ai.*)
State written with the standard `vibes.save` / `vibes.load` methods is private to each user and is **NOT readable by AI agents**. To share state with an AI agent (via the MCP connector), use the `vibes.ai` sub-namespace:
| Method | Description |
|--------|-------------|
| `await vibes.ai.setState(key, value)` | Write agent-readable state. Key is stored internally as `ai/<key>`. |
| `await vibes.ai.getState(key)` | Read agent-readable state. Returns `null` if key absent. |
| `await vibes.ai.listKeys()` | List all agent-readable keys (without the `ai/` prefix). |
**Important rules:**
- Regular `vibes.save()` / `vibes.load()` is **NOT agent-accessible** — use `vibes.ai.*` for state you want agents to read.
- The widget **owner** must enable agent access in **Manage → Agent tab** before any agent can read or write `vibes.ai.*` state.
- Keys are auto-prefixed to `ai/` internally; you supply just the short key (e.g. `'context'`).
```js
vibes.onReady(async () => {
// Write state an AI agent can later read
await vibes.ai.setState('context', { currentLevel: 3, score: 1500 });
// Read it back (same auto-prefix applies)
const ctx = await vibes.ai.getState('context');
// List all agent-accessible keys for this widget
const keys = await vibes.ai.listKeys(); // e.g. ['context']
});
```
### Rules
1. **Do NOT use localStorage, sessionStorage, or window.storage** — they are blocked or undefined in the sandbox. Use `vibes.save`/`vibes.load` instead.
2. **Do NOT add a script tag to import the SDK** — it is auto-injected.
3. **Wrap startup code in `vibes.onReady()`** — the SDK may not be ready immediately.
4. **Await all SDK calls** — every method (except `vibes.shared.get`) returns a Promise.
5. **External JS libraries are allowed and encouraged** — load them via a `<script src>` tag from a reputable CDN (jsDelivr, unpkg, or cdnjs) with a pinned version, or inline the library source. The only exception: do NOT add a script tag for the Vibes SDK itself — it is auto-injected (see Rule 2).
6. **Keep total code under 100KB** — that is the default widget size limit (your account limit may be higher).
### Rate Limits
| Operation | Limit |
|-----------|-------|
| Writes (save + delete combined) | 30/min |
| Reads (load) | 60/min |
| List keys | 30/min |
| Fetch proxy | Rate limited per widget |
### Error Handling
All SDK methods can reject. Wrap in try/catch:
```js
try {
await vibes.save("key", value);
} catch (err) {
console.error("Save failed:", err.message);
}
```
Fetch proxy errors include `err.code`: `"RATE_LIMITED"`, `"BLOCKED"`, `"FETCH_ERROR"`, and `"SECRET_NOT_FOUND"` (unknown or paused `useSecret` name). `vibes.browserKey` rejects only with `"RATE_LIMITED"` or `"FETCH_ERROR"`.
### Data Export
Export rows of data as CSV or Excel directly from your widget.
```js
// Register dataset for the platform's "Export data" button
// AND optionally trigger an immediate download
vibes.exportData(rows, { filename: 'results.csv' })
// rows: Array of arrays (each inner array is one row; first row = headers)
// options.filename: sets the download filename and format (csv or xlsx)
// options.directDownload: false to only register without downloading (default: true)
```
| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `filename` | string | `'data.csv'` | Download filename; extension determines format (`.csv` or `.xlsx`) |
| `directDownload` | boolean | `true` | Trigger immediate browser download in addition to registering the dataset |
**Notes:**
- First call registers the dataset so the widget chrome shows an "Export data" button
- Use `.csv` extension for CSV, `.xlsx` for Excel
- CSV injection safety is automatic (formula-starting cells prefixed with `'`)
- Data stays in the browser — no server round-trip
