What it does

Mira Animator is an agent skill from sandeco/mira-animator. Cria e evolui a animação de um slide como METÁFORA visual animada (o M de MIRA): destila o conceito, acha uma analogia concreta do cotidiano e a anima com loop interno obrigatório, em D3.js v7+ ou CSS 3D, no padrão dos decks de mira-templates/decks/ (glass-card, icon-hero, attribute-pills, replay-btn). Dois modos, CRIAR um slide animado novo e SUBSTITUIR a animação de um slide existente no lugar. Use SEMPRE que o usuário disser "/mira-animator", "criar slide animado", "novo slide com animação", "adicionar card…

Its SKILL.md is about 11k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/api-core.md`, `references/diretrizes-d3.md` and `references/interatividade.md`).

It sits in Documents & Office, covering Slides and decks. It works with D3.js. 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-animator”
  • “criar slide animado”
  • “novo slide com animação”
  • “/mira-animator”

Requirements

  • Node.js

Workflow steps

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

  1. Dinâmica como causa: Quando [causa], [estado] muda de [A] para [B] porque [mecanismo]. Se [falha], [consequência].
  2. A/B, duas candidatas e só. A é a que veio à cabeça primeiro, anote sem julgar. B é obrigatoriamente de outra família de domínio (casa…
  3. Mapeie papel, estado, ação causal e evidência visual de cada uma. ❌ Rejeite quem preserva os substantivos mas troca direção, condição…
  4. Contrafactual: a MESMA cena mostra o que acontece se uma parte falha, atrasa ou não age. ❌ Se precisar de outra analogia para mostrar a…
  5. Especificidade. ❌ Se a cena servir sem alteração para três conceitos não relacionados, é decoração.
  6. Distância útil. ❌ A associação lexical imediata (orquestração → maestro, fluxo → rio, memória → gaveta) perde o desempate: só vence se a…
  7. História: estado inicial, causa, transformação, consequência, recuperação. ❌ Se só der "A vira B" ou "tudo pulsa", volte ao passo 2.
  8. Loop da AÇÃO PRINCIPAL em uma frase. Ambiente, brilho, órbita e pulso não contam. ❌ Sem loop descritível, não serve.

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

    Shell commands in SKILL.md call:

    • npx

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

  • Network

    No URLs in SKILL.md. Its commands use npx, 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 Animator loads about 11k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 220 tokens; SKILL.md has 6,190 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~220
When it runs · the whole SKILL.md, loaded when a task matches
~11k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~12k

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 6,190 words (~11,353 tokens).

“MIRA é Metáforas Inteligentes Responsivas Animadas. A metáfora não é um modo especial desta skill, é o produto dela.”
