What it does

Mira History is an agent skill from sandeco/mira-animator. Transforma o texto de uma história (normalmente infantil) numa animação narrada no Mira: cenas com câmera e clima, atores em SVG, narração, música e QR para o celular. Use em /mira-history, "anima essa história", "história animada", "conto animado" ou conto colado pedindo animação. Num deck dela (tem mira/historia.js), também gera o vídeo mp4 da história (inclusive para WhatsApp) e prompt de música para o Suno. Vídeo de deck comum é do /mira-slide-to-video. Não é para explicar conceito nem slide comum.

Its SKILL.md is about 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 `references/esqueleto-historia.js`, `references/roteiro-gabarito.md` and `references/vocabulario.md`).

It sits in Documents & Office, covering Slides and decks. It works with Suno and WhatsApp. 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

“anima essa história”
“história animada”
“conto animado”
“/mira-history”

Requirements

Node.js

Workflow steps

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

references/vocabulario.md inteiro. É a lista fechada do que o runtime entende. Campo fora dela é erro.
references/esqueleto-historia.js: só a sintaxe do arquivo, com lugares vazios em MAIÚSCULAS. Não é uma história.
references/roteiro-gabarito.md: o formato do roteiro que você escreve antes do historia.js.

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 7 files in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
- node
- ffmpeg
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:
- openclipart.org
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 History loads about 4k tokens when it runs, and up to ~8.1k if it reads all its reference files. Until then it costs about 130 tokens; SKILL.md has 2,302 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~130
When it runs · the whole SKILL.md, loaded when a task matches: ~4k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~8.1k

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 2,302 words (~4,038 tokens).

“O autor cola uma história. Você entrega uma pasta em decks/ que abre com duplo clique no index.html e conta a história sozinha: cenas animadas, narração, música, botão verde para avançar, tela cheia, QR na capa para o celular.”
