What it does

Mira Slide To Video is an agent skill from sandeco/mira-animator. Gera um .mp4 de um ou mais slides de um deck do Mira gravando a animação real (Chrome headless + ffmpeg): cada slide dispara do zero, sem vazar o anterior, preenchendo o frame. Recebe quais slides (um, vários ou todos) e a resolução (16:9, 9:16, 1:1), encadeia com transição (4 segundos por slide, alterável), toca animações finitas como o chart-race por inteiro e nunca toca no deck original. Use SEMPRE que o usuário disser /mira-slide-to-video, gerar vídeo do slide, transformar slide em vídeo, exportar slide como…

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts.

It sits in Documents & Office, covering Slides and decks. It works with FFmpeg and Puppeteer. The repository describes itself as: Agentes e templates para criação de slides animados com D3.js em HTML.

When your agent uses it

  • Tasks that involve Slides and decks

Example prompts

  • “/mira-slide-to-video”

Requirements

  • Node.js

Workflow steps

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

  1. Conferir ffmpeg: ffmpeg -version. Se não houver, avise o usuário (Windows: baixar em gyan.dev e pôr no PATH, ou setar MIRA_FFMPEG). Sem…
  2. Instalar os pacotes uma vez (pule se node_modules/puppeteer-screen-recorder ja existir na pasta temp)
  3. Rodar com NODE_PATH para a pasta temp

What it can do on your machine

Read from SKILL.md and the folder at commit d857f32. 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 2 files in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • npm
    • ffmpeg

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

  • Network

    No URLs in SKILL.md. Its commands use 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

Mira Slide To Video loads about 2k tokens when it runs. Until then it costs about 199 tokens; SKILL.md has 978 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~199
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 978 words (~2,012 tokens).

“Grava a animação real de um ou mais slides de um deck e entrega um único .mp4. Casos típicos: exportar um slide para Reels/Shorts, gerar um teaser do deck, mandar um trecho animado por WhatsApp.”
