Valida o HTML gerado pela /mira-builder, checando conformidade visual, estrutural e de assets.

  • Tasks that involve Slides and decks
  • SKILL.md covers Objetivo, Fluxo de Execução, Checklist de Verificações and Passo 4: Gerar o Relatório, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Mira Validator is an agent skill from sandeco/mira-animator. Valida o HTML gerado pela /mira-builder, checando conformidade visual, estrutural e de assets. Use SEMPRE que a /mira-builder terminar de gerar um index.html, ou quando o usuário quiser verificar a qualidade de uma apresentação existente, revisar se os slides seguem o padrão, ou diagnosticar problemas visuais em slides já criados.

Its SKILL.md is about 1.8k 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-validator”

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.

    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 Validator loads about 1.8k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 742 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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 742 words (~1,795 tokens).

“Inspecionar o index.html gerado pela /mira-builder e produzir um relatório de conformidade: estilo, assets, estrutura HTML e boas práticas do padrão do projeto. Chamada automaticamente pela /mira-builder após gerar o HTML, ou manualmente para validar uma apresentação existente.”
