Remotion Video Factory

What it does

When your agent uses it

• Tasks that involve Video production
• Tasks that involve Text to speech and voice

Example prompts

• “图解动画 + AI 配音”
• “给我一个主题做个会动的技术动画”
• “画面要精确/可改/文字不能乱码”
• “/remotion-video-factory”

Requirements

• Python 3
• Node.js

Workflow steps

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

1. 1视觉从代码生长：一切图形用 React/SVG 组件绘制，参数来自数据；禁止截图当动画、禁止 AI 视频模型生成画面（公式必乱码、连线必漂移）。
2. 2一段旁白 = 一个场景；场景时长 = max(visualMin, 配音实测帧数 + tail(默认40f))，由 build-timeline.mjs 自动重建时间线——改稿/换语速不手调任何一镜，画面出点（fade(frame, D)）自动跟随。
3. 3确定性渲染：禁 Date.now() / Math.random() / 网络/环境变量依赖；伪随机一律 mulberry32(seed)。同样输入必须渲出同样的帧——这是可回归、可迭代的前提。
4. 4三层音频独立可验证：VO（主）+ BGM（bgm inputProp 开关，产出无 BGM 版供后期自配乐）+ SFX 钉帧表（from: SHOTS.x.from + offset 相对帧表达式，时间线平移自动跟随）。
5. 5每镜头完成即 QA 静帧（npx remotion still --frame=...），不攒到最后；全片渲完再抽帧回看关键镜头 + ffprobe/volumedetect 验收音轨。
6. 6src/timeline.ts 与 src/types.ts 由脚本生成，勿手改；手改数据只碰 VOICEOVER_ZH.md、build/scenes.json、DESIGN.md 三处。

What it can do on your machine

Read from SKILL.md and the folder at commit b98f166. 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/ (TypeScript, from the files we listed), which the agent can run.

  Shell commands in SKILL.md call:

  • npx
  • npm
  • node

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

• Network

  No URLs in SKILL.md. Its commands use npx and npm, which can reach the network depending on how they are called.

  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

Remotion Video Factory loads about 990 tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 150 tokens; SKILL.md has 132 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~150

When it runs · the whole SKILL.md, loaded when a task matches

~990

With references · SKILL.md plus every file in references/, read only if the agent opens them

~5k

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

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 132 words (~990 tokens).
