What it does

Mira Post It is an agent skill from sandeco/mira-animator. Mural de POST-ITS AO VIVO no Mira, em dois slides: no primeiro a pergunta com um QR-code, no segundo cada resposta em TEXTO LIVRE da plateia vira um post-it que cola na parede, um a um. Diferente do mira-survey e do mira-quiz, aqui a resposta é aberta, não há alternativas nem resposta correta, e nada é agregado: cada pessoa aparece com a frase dela. Use SEMPRE que o usuário disser /mira-post-it, post-it, mural de respostas, parede de respostas, resposta aberta, resposta em texto livre, pergunta aberta para a…

Its SKILL.md is about 4.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files.

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-post-it”

Requirements

  • Node.js

Workflow steps

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

  1. A plateia abre o link de votação pelo QR e escreve uma frase curta.
  2. Cada envio vira uma linha na planilha ligada ao Forms.
  3. O deck lê a planilha a cada poucos segundos pelo gviz.
  4. Enquanto o slide 1 está na tela, as respostas se acumulam numa fila.
  5. Quando o slide 2 fica visível, a fila drena: um post-it por vez, com cadência.
  6. O mural mostra 15 por página. A seta vira a página, e a página inédita cola do mesmo

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:

    • curl
    • npm
    • node
    • npx

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • docs.google.com

    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 Post It loads about 4.5k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 217 tokens; SKILL.md has 2,682 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~217
When it runs · the whole SKILL.md, loaded when a task matches
~4.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~14k

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 2,682 words (~4,467 tokens).
