What it does
Web Demo Video Synthesis is an agent skill from Sven-LI-sankyuu/presentation-skills. 用于“网页 demo 分段配音 + timeline 驱动录屏 + 后期合成”的 workspace 协作流程：先搭建一个可审计工作目录（cues/timeline/segmentaudio/video/subtitles/final），再由人类 + Codex 迭代维护这些文件，按需只重跑局部步骤，最终合成高质量 MP4。适用于强调可复盘、可编辑、清晰度与字幕安全区可控的场景。
Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 21 other files, including scripts and reference files (for example `agents/openai.yaml`, `package.json` and `references/quality_tuning.md`).
It sits in Media & Creative, covering Video production, Text to speech and voice and Transcription. It works with Python. The repository describes itself as: 面向 Codex CLI 的演示工作流 skills 集合，包括商业级可编辑 PPT 协作与网页 demo 配音视频合成等可复盘、可复用流程。A Codex CLI skill collection for reusable presentation workflows, covering editable PPT diagram…
When your agent uses it
- Tasks that involve Video production
- Tasks that involve Text to speech and voice
- Tasks that involve Transcription
Example prompts
- “网页 demo 分段配音 + timeline 驱动录屏 + 后期合成”
- “/web-demo-video-synthesis”
Requirements
- Python 3
- Node.js
- A Bash shell
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- 先锁定文案，再执行技术流水线。
- 语音必须按段生成（每段独立可重试，可定位失败）。
- timeline.json 是全链路主键：录屏、音频编排、字幕都基于它。
- 录屏阶段输出“无字幕母带”，字幕在最终合成阶段统一烧录。
- 禁止静默降级：缺参数、schema 错误、时序冲突必须直接报错。
What it can do on your machine
Read from SKILL.md and the folder at commit 1182af5. 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 10 files in scripts/ (Python, Shell and JavaScript, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python3bashnpxpipnpmnodeffmpeg
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:
help.aliyun.comnls-portal.console.aliyun.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Web Demo Video Synthesis loads about 3.2k tokens when it runs, and up to ~8.1k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 558 words of instructions outside code blocks.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 558 words (~3,198 tokens).
