What it does

Mira Size Animator is an agent skill from sandeco/mira-animator. Escala a percepção de tamanho das animações D3 de um deck numa escala de 1 a 10 (3/10 é o padrão gerado pelo mira-animator), lendo o marcador @MIRA:SIZE de cada animação e ajustando só o desenho dentro do SVG, sem mexer na altura do palco nem nos gatilhos. Use SEMPRE que o usuário disser "/mira-size-animator", "aumentar o tamanho da animação", "as animações estão pequenas", "a animação ocupa pouco espaço", "deixa tudo em 6/10", "coloca as animações em 5/10", "qual o tamanho das animações", "percepção de tamanho"…

Its SKILL.md is about 2.4k 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 Documents & Office, covering Slides and decks. 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-size-animator”
  • “aumentar o tamanho da animação”
  • “as animações estão pequenas”
  • “/mira-size-animator”

Workflow steps

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

  1. Localize o deck.
  2. Liste cada animação com seu nível atual (marcador, ou 3/10 se não houver).
  3. Apresente uma tabela curta: título do card → nível atual. Não edite nada.

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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are html).

    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

Mira Size Animator loads about 2.4k tokens when it runs. Until then it costs about 170 tokens; SKILL.md has 1,298 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~170
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

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); 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 1,298 words (~2,414 tokens).

“Regula o quanto cada animação D3 preenche o palco, numa escala de 1 a 10. Não cria animações nem muda a metáfora: pega o que o mira-animator já gerou e ajusta a escala da composição.”
