What it does

Explain Video is an agent skill from limin112/min-skill. Build a narrated explainer video from a concept — discussion → structure → HTML slide deck → narration script → TTS voice → subtitles → background music → Playwright screen recording → ffmpeg composite. Use when asked to make a 讲解视频 / explainer / talking-deck video, to turn a topic or article into a narrated video or animated slide deck, or to redo one stage of an existing deck (re-record, re-mix BGM, regenerate captions, swap the voice).

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including scripts and reference files (for example `README.md`, `scripts/build_srt.py` and `scripts/build_video.sh`).

It sits in Media & Creative, covering Text to speech and voice, Slides and decks and Video production. It works with FFmpeg and Playwright.

When your agent uses it

  • Asked to make a 讲解视频 / explainer / talking-deck video
  • Article into a narrated video
  • Animated slide deck
  • Redo one stage of an existing deck (re-record

Example prompts

  • “/explain-video”

Requirements

  • Python 3
  • A Bash shell

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Agree on the framework before writing anything
  2. Deck and narration together

What it can do on your machine

Read from SKILL.md and the folder at commit 9558302. 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 8 files in scripts/ (Python and Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • bash
    • pip
    • python
    • ffmpeg
    • python3
    • brew

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

  • Network

    No URLs in SKILL.md. Its commands use pip, 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

Explain Video loads about 2.4k tokens when it runs, and up to ~7.4k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 924 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~114
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.4k

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 924 words (~2,383 tokens).

“Turns a concept into a finished narrated video. No digital human, no avatar — an HTML deck is the source of truth, and everything else is generated from it.”
