What it does

Mira Squared is an agent skill from sandeco/mira-animator. Gera uma versão QUADRADA (1:1) de um deck do Mira a partir do 16:9 original, OU cria slides quadrados do zero quando não há deck de origem, para vídeo quadrado (feed do Instagram, LinkedIn, etc.). Não toca no original: cria index-1x1.html ao lado. Cada slide de conteúdo vira só o título no topo + a animação num canvas quadrado (lado = altura do 16:9, 100vh; laterais em 000), com o eixo reformulado por metáfora para preencher o quadrado. Texto, cores, timings e loop intactos. Use SEMPRE que o usuário disser…

Its SKILL.md is about 5.8k 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. It works with Instagram and LinkedIn. 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-squared”

Workflow steps

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

  1. Composição: só título + animação (CSS escopado)
  2. Palco = todo o resto da área segura + viewBox casado em runtime
  3. Reflow do eixo para o quadrado (preencher a maior parte)

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 javascript and 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 Squared loads about 5.8k tokens when it runs. Until then it costs about 183 tokens; SKILL.md has 2,602 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~183
When it runs · the whole SKILL.md, loaded when a task matches
~5.8k

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 2,602 words (~5,838 tokens).

“Transforma um deck 16:9 do Mira numa versão quadrada, para gravar como vídeo quadrado (feed do Instagram, LinkedIn). Cada slide de conteúdo vira só o título no topo + a animação grande num canvas quadrado, reformulada por metáfora para preencher…”
