aliyun-videoretalk is a skill for Codex from cinience/alicloud-skills. It costs 50 tokens per session (726 once invoked), scanned A, original, MIT.

A lip-sync replacement tool for Alibaba Cloud Model Studio that changes the mouth movements in an existing talking-person video to match a new speech recording.

In plain words
What is it for?
Use it to create dubbed videos or synchronize an existing person video with a new audio track through the VideoRetalk model.
Why use it?
It removes the need to reshoot a talking-head video when the narration or spoken language changes.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aliyun-videoretalk scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/prepare_retalk_request.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Category: provider

Model Studio VideoRetalk

Validation

mkdir -p output/aliyun-videoretalk
python -m py_compile skills/ai/video/aliyun-videoretalk/scripts/prepare_retalk_request.py && echo "py_compile_ok" > output/aliyun-videoretalk/validate.txt

Pass criteria: command exits 0 and output/aliyun-videoretalk/validate.txt is generated.

Output And Evidence

  • Save normalized request payloads, target face selection settings, and task polling snapshots under output/aliyun-videoretalk/.
  • Record the exact video/audio input URLs and whether video_extension was enabled.

Use VideoRetalk when the input is already a person video and the job is to replace lip sync with a new speech track.

Critical model names

Use this exact model string:

  • videoretalk

Prerequisites

  • This model currently only supports China mainland (Beijing).
  • API is HTTP async only; there is no online console experience.
  • Set DASHSCOPE_API_KEY in your environment, or add dashscope_api_key to ~/.alibabacloud/credentials.

Normalized interface (video.retalk)

Request

  • model (string, optional): default videoretalk
  • video_url (string, required)
  • audio_url (string, required)
  • ref_image_url (string, optional): target face when input video contains multiple faces
  • video_extension (bool, optional): extend video to match longer audio
  • query_face_threshold (int, optional): 120 to 200

Response

  • task_id (string)
  • task_status (string)
  • video_url (string, when finished)
  • usage (object, optional)

Endpoint and execution model

  • Submit task: POST https://dashscope.aliyuncs.com/api/v1/services/aigc/image2video/video-synthesis/
  • Poll task: GET https://dashscope.aliyuncs.com/api/v1/tasks/{task_id}
  • HTTP calls are async only and must set header X-DashScope-Async: enable.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
