What it does

Aliyun Happyhorse T2v is an agent skill from cinience/alicloud-skills. Use when generating videos from text prompts with DashScope HappyHorse 1.0 text-to-video model (happyhorse-1.0-t2v). Use when implementing pure text-to-video synthesis via the video-synthesis async API on Alibaba Cloud Model Studio.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/api_reference.md`, `references/sources.md` and `scripts/t2v_happyhorse.py`).

It sits in Media & Creative, covering AI video generation. It works with Alibaba Cloud. The repository describes itself as: alibaba cloud skills,qwen ,wan and all skills. The licence is MIT.

When your agent uses it

  • Generating videos from text prompts with DashScope HappyHorse 1.0 text-to-video model (happyhorse-1.0-t2v)
  • Implementing pure text-to-video synthesis via the video-synthesis async API on Alibaba Cloud Model Studio

Example prompts

  • “/aliyun-happyhorse-t2v”

Requirements

  • Python 3
  • A credential in DASHSCOPE_API_KEY
  • A credential in API_KEY

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Confirm pure text-to-video intent (no input image/video).
  2. Build the prompt and choose resolution, ratio, duration.
  3. Create async task and poll /tasks/{task_id} every ~15s.
  4. Download output.video_url before the 24-hour expiration.

What it can do on your machine

Read from SKILL.md and the folder at commit 1818263. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • dashscope.aliyuncs.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • DASHSCOPE_API_KEY
    • API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Aliyun Happyhorse T2v loads about 1.6k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 430 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Validation

bash
mkdir -p output/aliyun-happyhorse-t2v
python -m py_compile skills/ai/video/aliyun-happyhorse-t2v/scripts/t2v_happyhorse.py && echo "py_compile_ok" > output/aliyun-happyhorse-t2v/validate.txt

Output And Evidence

  • Save task IDs, polling responses, and final video URLs to output/aliyun-happyhorse-t2v/.
  • Keep at least one end-to-end run log for troubleshooting.

Prerequisites

  • Install dependencies (recommended in a venv):
bash
python3 -m venv .venv
. .venv/bin/activate
python -m pip install requests
  • Set DASHSCOPE_API_KEY in your environment, or add dashscope_api_key to ~/.alibabacloud/credentials.

Critical model names

    "prompt": "一座由硬纸板和瓶盖搭建的微型城市,在夜晚焕发出生机。",
    "duration": 5,
})

# Vertical short video at 720P
task_id = create_t2v_task({
    "prompt": "A neon cyberpunk alley at midnight, rain reflections, slow dolly forward.",
    "resolution": "720P",
    "ratio": "9:16",
    "duration": 8,

Output location

  • Default output: output/aliyun-happyhorse-t2v/videos/
  • Override base dir with OUTPUT_DIR.

Anti-patterns

  • Do not use any model ID other than happyhorse-1.0-t2v.
  • Do not call this API synchronously — async header is required.
  • Do not pass media, first_frame, or reference_image — t2v takes only a text prompt.
  • Video and task URLs expire after 24 hours; download and persist immediately.
  • Do not use this skill for image- or video-conditioned generation — use aliyun-happyhorse-i2v, aliyun-happyhorse-r2v, or aliyun-happyhorse-videoedit instead.

Workflow

  1. Confirm pure text-to-video intent (no input image/video).
  2. Build the prompt and choose resolution, ratio, duration.
  3. Create async task and poll /tasks/{task_id} every ~15s.
  4. Download output.video_url before the 24-hour expiration.
