What it does

Mira Webview is an agent skill from sandeco/mira-animator. Coloca um site vivo dentro de um slide do Mira (novo ou existente), ocupando o slide inteiro (edge to edge) via iframe full-bleed. Resolve os dois problemas de embutir um site num deck: o iframe rouba o foco do teclado (uma guarda de interação deixa o site só visível até o apresentador clicar, e Esc devolve o controle ao deck) e sites que bloqueiam incorporação por X-Frame-Options ou CSP frame-ancestors (fallback com link, ou baixar o site para assets/webview/ e rodar offline por file protocol). Herda a Regra…

Its SKILL.md is about 3.8k 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. 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-webview”

Workflow steps

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

  1. Foco / navegação. Assim que o iframe pega foco, ArrowRight/ArrowDown/PageDown vão para o site, não para o deck, e o apresentador fica…
  2. Sites que bloqueiam incorporação. Google, YouTube (home), bancos, Instagram e muitos outros mandam X-Frame-Options: DENY ou…

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

    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:

    • exemplo.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 Webview loads about 3.8k tokens when it runs. Until then it costs about 203 tokens; SKILL.md has 1,169 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~203
When it runs · the whole SKILL.md, loaded when a task matches
~3.8k

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 1,169 words (~3,808 tokens).

“Insere num slide um site que ocupa o slide inteiro (edge to edge, sem moldura por padrão), via full-bleed. Casos típicos: demonstrar o produto ao vivo, abrir a landing page durante o pitch, mostrar um dashboard, um CodePen, um mapa…”
