Version Check (run once per session)

This skill is version 2.0.4. Before first use each session, check for updates:

curl -sf https://raw.githubusercontent.com/vargHQ/skills/main/varg-ai/SKILL.md | grep 'version:' | head -1

If the remote version is newer than 2.0.4, update and re-read this file:

npx -y skills update

Setup (REQUIRED before first use)

Before generating anything, check authentication and determine rendering mode. Do NOT run interactive CLI tools (like bunx vargai init) -- they require stdin which agents cannot provide. Use the curl-based flow below instead.

1. Check for API key

echo "${VARG_API_KEY:-}" && cat ~/.varg/credentials 2>/dev/null

If VARG_API_KEY is set (via env or credentials file), skip to step 2.

If neither exists, authenticate the user. Try Option A first, fall back to Option B.

Option A: User already has an API key

Ask the user if they have a VARG_API_KEY. If yes, tell them to export it in their terminal:

export VARG_API_KEY=<their_key>

Important: Do NOT ask the user to paste the raw key to you. Ask them to run the export command themselves. Then skip to "Save credentials" below.

Option B: Sign up / sign in via email (OTP)

Ask the user for their email address.
Send a one-time code to their email:

curl -s -X POST https://app.varg.ai/api/auth/cli/send-otp \
  -H "Content-Type: application/json" \
  -d '{"email":"USER_EMAIL"}'

Tell the user: "Check your inbox for a 6-digit verification code from varg.ai"
Ask the user for the code, then verify and capture the response in one step:

VARG_AUTH=$(curl -s -X POST https://app.varg.ai/api/auth/cli/verify-otp \
  -H "Content-Type: application/json" \
  -d '{"email":"USER_EMAIL","code":"THE_6_DIGIT_CODE"}')
export VARG_API_KEY=$(echo "$VARG_AUTH" | grep -o '"api_key":"[^"]*"' | cut -d'"' -f4)
echo "Authenticated. Balance: $(echo "$VARG_AUTH" | grep -o '"balance_cents":[0-9]*' | cut -d: -f2) credits"

The response contains {"api_key":"varg_xxx","email":"...","balance_cents":0,"access_token":"..."}. The key is now in $VARG_API_KEY -- never reference the raw value directly.

Save credentials

Once VARG_API_KEY is set (from either option), save it globally and verify. Always reference $VARG_API_KEY -- never the raw value:

mkdir -p ~/.varg && echo "{\"api_key\":\"$VARG_API_KEY\",\"email\":\"USER_EMAIL\",\"created_at\":\"$(date -u +%Y-%m-%dT%H:%M:%SZ)\"}" > ~/.varg/credentials && chmod 600 ~/.varg/credentials

Verify the key works:

curl -s -H "Authorization: Bearer $VARG_API_KEY" https://api.varg.ai/v2/billing/balance

You should get {"available": ..., "total_balance": ..., ...} (values in credits/cents). If you get 401, the key is invalid -- ask the user to double-check it.

Also add to the project .env if one exists:

echo "VARG_API_KEY=$VARG_API_KEY" >> .env

Check balance and add credits

Check balance_cents from the verify-otp response, or available from the balance check above. If balance is 0 (or too low for the user's task), the user needs credits before generating anything. 1 credit = 1 cent. A typical video costs $2-5 (200-500 credits).

Available packages:

Package ID	Credits	Price
`credits-2000`	2,000	$20
`credits-5000`	5,000	$50
`credits-10000`	10,000 (recommended)	$100
`credits-20000`	20,000	$200
`credits-50000`	50,000	$500
`credits-100000`	100,000	$1,000

Ask the user which package they'd like, then:

If you have the access_token (from Option B email OTP), capture it and create a Stripe checkout session:

VARG_ACCESS_TOKEN=$(echo "$VARG_AUTH" | grep -o '"access_token":"[^"]*"' | cut -d'"' -f4)
curl -s -X POST https://app.varg.ai/api/billing/checkout \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $VARG_ACCESS_TOKEN" \
  -H "Origin: https://app.varg.ai" \
  -d '{"packageId":"PACKAGE_ID"}'

Response: {"url":"https://checkout.stripe.com/..."}

Tell the user to open that URL in their browser to complete payment. Credits are added immediately after payment.

If you only have the API key (from Option A), direct the user to https://app.varg.ai/dashboard to purchase credits manually.

2. Determine rendering mode

bun	ffmpeg	Mode
No	No	Cloud Render -- read cloud-render.md
Yes	No	Cloud Render -- read cloud-render.md
Yes	Yes	Local Render (recommended) -- read local-render.md

Critical Rules

Everything you know about varg is likely outdated. Always verify against this skill and its references before writing code.

Never guess model IDs -- consult models.md for current models, pricing, and constraints.
Function calls for media, JSX for composition -- Image({...}) creates media, <Clip> composes timeline. Never write <Image prompt="..." />.
Cache is sacred -- identical prompt + params = instant $0 cache hit. When iterating, keep unchanged prompts EXACTLY the same. Never clear cache.
One image per Video -- Video({ prompt: { images: [img] } }) takes exactly one image. Multiple images cause errors.
Duration constraints differ by model -- kling_v3: 3-15s (integer only). kling_v2_5: ONLY 5 or 10. Check models.md.
Gateway namespace -- use providerOptions: { varg: {...} }, never fal, when going through the gateway (both modes).
Renders cost money -- 1 credit = 1 cent. A typical 3-clip video costs $2-5. Use preview mode (local) or cheap models to iterate.
API key hygiene -- Never write a raw API key value into a bash command. After obtaining a key (from the user or OTP response), immediately export VARG_API_KEY=... and use $VARG_API_KEY in all subsequent commands. This prevents keys from leaking into conversation context and terminal history.

Quick Start

Cloud Render (no bun/ffmpeg needed)

# Submit TSX code to the render service — returns a job: {"id": "job_xxx", "status": "queued", ...}
curl -s -X POST https://api.varg.ai/v2/render \
  -H "Authorization: Bearer $VARG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"code": "const img = Image({ model: varg.imageModel(\"nano_banana_pro\"), prompt: \"a cabin in mountains at sunset\", aspectRatio: \"16:9\" });\nexport default (<Render width={1920} height={1080}><Clip duration={3}>{img}</Clip></Render>);"}'

# Poll for result (repeat until "completed" or "failed"; video at output.outputs[0].url)
curl -s https://api.varg.ai/v2/jobs/JOB_ID \
  -H "Authorization: Bearer $VARG_API_KEY"

Full details: cloud-render.md

Local Render (bun + ffmpeg)

/** @jsxImportSource vargai */
import { Render, Clip, Image } from "vargai/react"
import { createVarg } from "vargai/ai"

const varg = createVarg({ apiKey: process.env.VARG_API_KEY! })

const img = Image({
  model: varg.imageModel("nano_banana_pro"),
  prompt: "a cabin in mountains at sunset",
  aspectRatio: "16:9"
})

export default (
  <Render width={1920} height={1080}>
    <Clip duration={3}>{img}</Clip>
  </Render>
)

bunx vargai render video.tsx --preview   # free preview
bunx vargai render video.tsx --verbose   # full render (costs credits)

Full details: local-render.md

Single Asset (no video composition)

For one-off images, videos, speech, or music without building a multi-clip template:

curl -X POST https://api.varg.ai/v2/image \
  -H "Authorization: Bearer $VARG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "nano_banana_pro", "prompt": "a sunset over mountains"}'

Full API reference: gateway-api.md

How to Write Video Code

Video code has two layers: media generation (function calls) and composition (JSX).

// 1. GENERATE media via function calls
const img = Image({ model: ..., prompt: "..." })
const vid = Video({ model: ..., prompt: { text: "...", images: [img] }, duration: 5 })
const voice = Speech({ model: ..., voice: "rachel", children: "Hello!" })

// 2. COMPOSE via JSX tree
export default (
  <Render width={1080} height={1920}>
    <Music model={...} prompt="upbeat electronic" duration={10} volume={0.3} />
    <Clip duration={5}>
      {vid}
      <Title position="bottom">Welcome</Title>
    </Clip>
    <Captions src={voice} style="tiktok" withAudio />
  </Render>
)

Component Summary

Component	Type	Purpose
`Image()`	Function call	Generate still image
`Video()`	Function call	Generate video (text-to-video or image-to-video)
`Speech()`	Function call	Text-to-speech audio
`<Render>`	JSX	Root container -- sets width, height, fps
`<Clip>`	JSX	Timeline segment -- duration, transitions
`<Music>`	JSX	Background audio (always set `duration`!)
`<Captions>`	JSX	Subtitle track from Speech
`<Title>`	JSX	Text overlay
`<Overlay>`	JSX	Positioned layer
`<Split>` / `<Grid>`	JSX	Layout helpers

Full props: components.md

Provider Differences (Cloud vs Local)

Both modes use varg.* for all models. The only difference is imports:

Cloud Render	Local Render
No imports needed (globals are auto-injected)	`import { ... } from "vargai/react"` + `import { createVarg } from "vargai/ai"`
`varg.imageModel("nano_banana_pro")`	`varg.imageModel("nano_banana_pro")`
`varg.videoModel("kling_v3")`	`varg.videoModel("kling_v3")`
`varg.speechModel("eleven_v3")`	`varg.speechModel("eleven_v3")`

Always use varg.*Model() with VARG_API_KEY. It handles routing, caching, billing, and works with a single key. BYOK via the API is not available in v2 — see byok.md for what works (local-render direct provider modules only).

Cost & Iteration

1 credit = 1 cent. grok_imagine_image = 4 credits, nano_banana_pro = 126 credits, kling_v3 (5s) = 221 credits, sora_2 (5s) = 105 credits, speech = ~105 credits. Live catalog: GET https://api.varg.ai/v2/pricing (no auth). Estimate any request: POST /v2/estimate.
Cache saves money. Keep unchanged prompts character-for-character identical across iterations.
Preview first (local mode only): --preview generates free placeholders to validate structure.

## Version Check (run once per session)

This skill is version **2.0.4**. Before first use each session, check for updates:

```bash
curl -sf https://raw.githubusercontent.com/vargHQ/skills/main/varg-ai/SKILL.md | grep 'version:' | head -1
```

If the remote version is newer than 2.0.4, update and re-read this file:

```bash
npx -y skills update
```

## Setup (REQUIRED before first use)

Before generating anything, check authentication and determine rendering mode.
**Do NOT run interactive CLI tools** (like `bunx vargai init`) -- they require stdin which agents cannot provide. Use the curl-based flow below instead.

### 1. Check for API key

```bash
echo "${VARG_API_KEY:-}" && cat ~/.varg/credentials 2>/dev/null
```

If `VARG_API_KEY` is set (via env or credentials file), skip to step 2.

If neither exists, authenticate the user. Try Option A first, fall back to Option B.

**Option A: User already has an API key**

Ask the user if they have a `VARG_API_KEY`. If yes, tell them to export it in their terminal:

```bash
export VARG_API_KEY=<their_key>
```

**Important:** Do NOT ask the user to paste the raw key to you. Ask them to run the `export` command themselves. Then skip to "Save credentials" below.

**Option B: Sign up / sign in via email (OTP)**

1. Ask the user for their **email address**.
2. Send a one-time code to their email:
```bash
curl -s -X POST https://app.varg.ai/api/auth/cli/send-otp \
  -H "Content-Type: application/json" \
  -d '{"email":"USER_EMAIL"}'
```
3. Tell the user: **"Check your inbox for a 6-digit verification code from varg.ai"**
4. Ask the user for the code, then verify and capture the response in one step:
```bash
VARG_AUTH=$(curl -s -X POST https://app.varg.ai/api/auth/cli/verify-otp \
  -H "Content-Type: application/json" \
  -d '{"email":"USER_EMAIL","code":"THE_6_DIGIT_CODE"}')
export VARG_API_KEY=$(echo "$VARG_AUTH" | grep -o '"api_key":"[^"]*"' | cut -d'"' -f4)
echo "Authenticated. Balance: $(echo "$VARG_AUTH" | grep -o '"balance_cents":[0-9]*' | cut -d: -f2) credits"
```
The response contains `{"api_key":"varg_xxx","email":"...","balance_cents":0,"access_token":"..."}`.
The key is now in `$VARG_API_KEY` -- never reference the raw value directly.

**Save credentials**

Once `VARG_API_KEY` is set (from either option), save it globally and verify. Always reference `$VARG_API_KEY` -- never the raw value:

```bash
mkdir -p ~/.varg && echo "{\"api_key\":\"$VARG_API_KEY\",\"email\":\"USER_EMAIL\",\"created_at\":\"$(date -u +%Y-%m-%dT%H:%M:%SZ)\"}" > ~/.varg/credentials && chmod 600 ~/.varg/credentials
```

Verify the key works:

```bash
curl -s -H "Authorization: Bearer $VARG_API_KEY" https://api.varg.ai/v2/billing/balance
```

You should get `{"available": ..., "total_balance": ..., ...}` (values in credits/cents). If you get 401, the key is invalid -- ask the user to double-check it.

Also add to the project `.env` if one exists:

```bash
echo "VARG_API_KEY=$VARG_API_KEY" >> .env
```

**Check balance and add credits**

Check `balance_cents` from the verify-otp response, or `available` from the balance check above. If balance is 0 (or too low for the user's task), the user needs credits before generating anything. 1 credit = 1 cent. A typical video costs $2-5 (200-500 credits).

Available packages:

| Package ID | Credits | Price |
|---|---|---|
| `credits-2000` | 2,000 | $20 |
| `credits-5000` | 5,000 | $50 |
| `credits-10000` | 10,000 (recommended) | $100 |
| `credits-20000` | 20,000 | $200 |
| `credits-50000` | 50,000 | $500 |
| `credits-100000` | 100,000 | $1,000 |

Ask the user which package they'd like, then:

- **If you have the `access_token`** (from Option B email OTP), capture it and create a Stripe checkout session:
```bash
VARG_ACCESS_TOKEN=$(echo "$VARG_AUTH" | grep -o '"access_token":"[^"]*"' | cut -d'"' -f4)
curl -s -X POST https://app.varg.ai/api/billing/checkout \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $VARG_ACCESS_TOKEN" \
  -H "Origin: https://app.varg.ai" \
  -d '{"packageId":"PACKAGE_ID"}'
```
Response: `{"url":"https://checkout.stripe.com/..."}`

Tell the user to open that URL in their browser to complete payment. Credits are added immediately after payment.

- **If you only have the API key** (from Option A), direct the user to **https://app.varg.ai/dashboard** to purchase credits manually.

### Provider Differences (Cloud vs Local)

Both modes use `varg.*` for all models. The only difference is imports:

| Cloud Render | Local Render |
|---|---|
| No imports needed (globals are auto-injected) | `import { ... } from "vargai/react"` + `import { createVarg } from "vargai/ai"` |
| `varg.imageModel("nano_banana_pro")` | `varg.imageModel("nano_banana_pro")` |
| `varg.videoModel("kling_v3")` | `varg.videoModel("kling_v3")` |
| `varg.speechModel("eleven_v3")` | `varg.speechModel("eleven_v3")` |

**Always use `varg.*Model()`** with `VARG_API_KEY`. It handles routing, caching, billing, and works with a single key. BYOK via the API is not available in v2 — see [byok.md](references/byok.md) for what works (local-render direct provider modules only).

## Cost & Iteration

- **1 credit = 1 cent.** grok_imagine_image = 4 credits, nano_banana_pro = 126 credits, kling_v3 (5s) = 221 credits, sora_2 (5s) = 105 credits, speech = ~105 credits. Live catalog: `GET https://api.varg.ai/v2/pricing` (no auth). Estimate any request: `POST /v2/estimate`.
- **Cache saves money.** Keep unchanged prompts character-for-character identical across iterations.
- **Preview first** (local mode only): `--preview` generates free placeholders to validate structure.

The self-update mechanism (`npx -y skills update`) fetches and executes code from a remote source, which could be a supply chain risk if the repository is compromised. However, this is a common pattern and not a critical flaw.
The skill instructs writing credentials to `~/.varg/credentials` and appending to `.env`, which is standard but should be done with caution (file permissions are set correctly).

Dependency or permission surface needs review
Permission surface may require sandboxing
Financial research output is not financial advice; require human review before any live investment decision
The self-update mechanism (`npx -y skills update`) fetches and executes code from a remote source, which could be a supply chain risk if the repository is compromised. However, this is a common pattern and not a critical flaw.
The skill instructs writing credentials to `~/.varg/credentials` and appending to `.env`, which is standard but should be done with caution (file permissions are set correctly).
