What it does

Mira Studio is an agent skill from sandeco/mira-animator. Gera um deck VERTICAL 9:16 (1080x1920) pronto para gravar no OBS Studio, onde cada slide declara um de três layouts: camera (webcam ao vivo em tela cheia), split (animação quadrada estilo mira-squared em cima + câmera embaixo) e full (animação vertical estilo mira-vertical). A câmera do apresentador é embutida ao vivo no slide via getUserMedia (módulo mira/mira-camera.js), sem chroma key: no OBS basta capturar a janela. Sem câmera, a área vira verde chroma 00FF00 como plano B. Use SEMPRE que o usuário disser…

Its SKILL.md is about 9.3k 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-studio”

Requirements

Node.js

Workflow steps

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

camera → gere só . Nada de texto por cima (a fala é do apresentador).
split → título curto (máx. 6 palavras) + metáfora animada PENSADA PARA O QUADRADO (radial/orbital/hub rende mais) + .cam-area embaixo.
full → título curto + metáfora animada PENSADA PARA O RETRATO (eixo dominante vertical: fluxo desce, comparação empilha).

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
- node
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 Studio loads about 9.3k tokens when it runs. Until then it costs about 182 tokens; SKILL.md has 4,943 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~182
When it runs · the whole SKILL.md, loaded when a task matches: ~9.3k

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 4,943 words (~9,345 tokens).

“A primeira ação é resolver deck_id = YYYY-MM-DD com a data atual e criar, de uma vez, a pasta do deck e toda a árvore interna: references/, assets/, assets/vendor/ e mira/. Nenhuma dessas pastas fica para depois. Isso acontece antes…”
