What it does

Mira Visuals is an agent skill from sandeco/mira-animator. Gera imagens estáticas para slides do Mira: painéis 1920x800, infográficos 1920x1920, diagramas técnicos e gráficos — via D3.js com captura PNG, ou fotorrealismo via prompt JSON (mira-image-prompt). Use esta skill SEMPRE que o usuário disser: "criar imagem", "gerar imagem", "ilustração", "diagrama", "gráfico estático", "infográfico", "resumo visual", "quadro resumo", "imagem para o slide", "visual para o deck", ou qualquer variação sobre criar elementos visuais estáticos. Para ANIMAÇÕES use /mira-animator; esta…

Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/legacy-illustrator.md` and `references/legacy-infographic.md`).

It sits in Documents & Office, covering Slides and decks. It works with D3.js and Adobe Illustrator. 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

“criar imagem”
“gerar imagem”
“ilustração”
“/mira-visuals”

Workflow steps

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

Idioma: siga agents/_shared/idioma.md — todo texto visível revisado, acentuação 100% correta.
Regra de ouro: o conteúdo visual tem prioridade total sobre molduras e títulos decorativos.
Legibilidade: fontes grandes (mínimo 28px em canvas 1920), hierarquia clara, contraste alto.
Cores: use as CSS variables do tema do deck (--mira-primary etc.), nunca hardcoded.
Output: salve SEMPRE em decks//assets/. Nunca escreva em fontes vinculadas.

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 1 file in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
- node
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 Visuals loads about 856 tokens when it runs, and up to ~7.4k if it reads all its reference files. Until then it costs about 140 tokens; SKILL.md has 336 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~140
When it runs · the whole SKILL.md, loaded when a task matches: ~856
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~7.4k

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); 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 336 words (~856 tokens).

“Fusão das antigas mira-illustrator (painéis 1920x800) e mira-infographic (quadrados 1920x1920). Uma única porta de entrada que escolhe formato e pipeline conforme o pedido.”
