What it does

Carocut Builder Compositor is an agent skill from bilibili/carocut. Remotion Shot 组件实现。将 storyboard 转化为 React 组件。包含关键的帧计算规则(Math.round 强制)、interpolate 安全规则(最小 1 帧)、1080p 视觉标准、动画编排模式、音视频同步架构、组件复用模式。这是技术密度最高的 skill。

Its SKILL.md is about 7.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Video production and Comics and storyboards. It works with Remotion and React. The repository describes itself as: Multi-Agent 的视频制作助手,基于 OpenCode AI SDK 和 Remotion 构建。

When your agent uses it

  • Tasks that involve Video production
  • Tasks that involve Comics and storyboards

Example prompts

  • “/carocut-builder-compositor”

Workflow steps

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

  1. Shared Components - FlatDecorations, Card, DataTable, BarChart, plus motion-graphics from resources.yaml components section
  2. Shot Components - Chapter-by-chapter implementation
  3. Audio Layers - VoiceoverLayer, BackgroundMusicLayer, SfxLayer
  4. Main Composition - Assembly with TransitionSeries

What it can do on your machine

Read from SKILL.md and the folder at commit 2f8dc10. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript, dot, bash and python).

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

  • Network

    No URLs in SKILL.md.

    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

Carocut Builder Compositor loads about 7.6k tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 1,543 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~7.6k

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); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,543 words (~7,630 tokens).

“Implements storyboard as Remotion React components. This is the core implementation phase where planning documents become working code.”
