How to make any AI video

varg how to (https://varg.ai/how-to) maps what people ask for ("a UGC ad for my serum", "a music video for my song", "TikTok captions") to the skills that make it, the choices to offer and the steps. It is a search index, not a model: one call, about 0.1-0.5 s, no key, any language.

1. Search once, with the person's own words

curl -s "https://varg.ai/how-to/api/search?q=<the request, URL-encoded>&client=<your agent, e.g. claude-code>"

The answer is Markdown with the best-matching how-to page, the options to show the person, and the top skills with exact install commands for Claude Code, Codex, Cursor, OpenClaw and Gemini CLI. Add &limit=15 for more. For JSON (ranked cards with kind, slug, markdown, install), call the API:

curl -s "https://api.varg.ai/v2/skills/search?q=<request>&limit=10&client=<your agent>"

Pass client (your agent's name) on every search. It is optional, but it shows varg which agents use the catalog, so it can rank better for them. Searches are logged without IP or key.

2. Read the how-to page it names

Every page has a Markdown twin: add .md to its path, for example https://varg.ai/how-to/make-a-ugc-ad-video.md. A how-to page lists the best skill ("Start here"), the alternatives and add-ons (captions, voice, music), the questions to ask with example links, the numbered steps, and how the generation runs on varg. The index of all pages is https://varg.ai/how-to/llms.txt.

3. Let the person choose before spending anything

Send one message with the 2-4 decisions that change the result (look, format, voice, length). Give each 2-4 options plus your recommended default, and put the page's example link next to every option that has one (- Selfie creator: example https://s3.varg.ai/...mp4). People choose a look by seeing it. Do not generate until they pick, unless they said to just go.

4. Install the chosen skill and run it

Use the install command from the page for the agent you are running in. Generation (images, video, voice, music, lip-sync, captions, render) runs on varg with one account: the varg-ai skill (npx skills add vargHQ/skills --skill varg-ai) or the varg MCP server https://mcp.varg.ai/mcp (OAuth sign-in, no key to paste). Quote the cost before a batch, a long video or a render (estimate_cost in the MCP, POST https://api.varg.ai/v2/estimate in the API).

Whole video, start to finish

One search finds one format skill. That is right for a clip, an ad in a known format, captions or an edit. When the person wants a whole piece made from scratch, properly (several shots, a story, a launch film, an explainer, a music video built from nothing), no single skill covers it: follow this production order instead, and search (step 1 above) only for the format skill a step needs.

Before step 1, set up the project with video-project-github (it creates the folders and the private repo, and the person only clicks once), then agree a spend cap and the paid models allowed. Estimate before every paid call and say the running total. Use video models only for what code cannot draw (real people, crowds, weather, physical motion). Each step writes one file; at every STOP, show it and wait.

The full prompt to paste, with every step spelled out and [brackets] to fill, is in references/whole-video-prompt.md.

As an MCP server (no key)

Agents that prefer tools over curl can add the public varg how to MCP server:

claude mcp add --transport http varg-how-to https://api.varg.ai/v2/skills/mcp

It has two read-only tools: search_how_to {query} and get_how_to {kind, slug}. The second returns a page as Markdown. If the server is unreachable, use the curl calls above; they give the same results.

Signed in (optional)

Anonymous search is enough to find and run anything. If a varg key is already on the machine, use it for a personal search that ranks what this person saved and used first. Never ask the person to paste a key into the chat.

[ -n "${VARG_API_KEY:-}" ] || export VARG_API_KEY=$(grep -o '"api_key"[^,}]*' ~/.varg/credentials 2>/dev/null | head -1 | cut -d'"' -f4)
[ -n "$VARG_API_KEY" ] && curl -s -H "Authorization: Bearer $VARG_API_KEY" "https://api.varg.ai/v2/skills/me/search?q=<request>&client=<your agent>"

A 404 or 401 means the personal search is not available for this key. Fall back to the public search. In the varg MCP (https://mcp.varg.ai/mcp), search_skills signs in through OAuth and does the same: the agent authorizes itself in the browser, and no key is copied.

List a skill you built

If you (or the person) built an agent skill that makes or edits video, images, voice or music, list it on varg how to so other agents find it:

• The full flow, with the one card format every listing uses: install the varg-publish-skill skill (npx skills add vargHQ/skills --skill varg-publish-skill).
• In the varg MCP: the publish-skill prompt, then publish_skill. my_skills shows the review status.
• With a key: POST https://api.varg.ai/v2/skills/submissions, with a JSON body like this:

curl -s -X POST https://api.varg.ai/v2/skills/submissions \
  -H "Authorization: Bearer $VARG_API_KEY" -H "Content-Type: application/json" \
  -d '{"name":"Lyric Video Maker","summary":"Turn a song into a karaoke-style lyric video for Reels.","source_url":"https://github.com/<you>/<repo>","install":"npx skills add <you>/<repo>","use_when":["make a lyric video","karaoke video for a song"],"tags":["lyric-video","music"],"via":"api"}'

• Without an agent: the form at https://varg.ai/how-to/publish.

Every submission is reviewed by the varg team before it goes live. Write the name as the task ("Turn a song into a lyric video"), not a brand.
