What it does

Mira New Plugin is an agent skill from sandeco/mira-animator. Cria um plugin do Mira, que é um agente novo feito pelo proprio usuario e que vive em mira-plugins/, fora do pacote do Mira. Orquestra o ciclo inteiro: confere se o Reversa esta instalado e instala se faltar, especifica com reversa-new, implementa com reversa-forward escrevendo dentro da pasta do plugin, valida o manifesto e ativa. Avisa que as specs ficam locais e nao viajam no pacote compartilhado. Use SEMPRE que o usuario disser /mira-new-plugin, criar plugin, novo plugin do Mira, quero fazer meu proprio…

Its SKILL.md is about 1.5k 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. The repository describes itself as: Agentes e templates para criação de slides animados com D3.js em HTML.

When your agent uses it

  • Documents & Office work in your project

Example prompts

  • “/mira-new-plugin”

Requirements

  • Node.js

Workflow steps

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

  1. O plugin é autocontido: nenhum arquivo dele mora fora da própria pasta.
  2. Nenhum arquivo executável (.js, .sh, .bat, .ps1, .py e afins). A primeira versão do sistema de plugins recusa por completo, porque o…
  3. O agente é um SKILL.md só, com references/ e assets/ opcionais ao lado.

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

    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 New Plugin loads about 1.5k tokens when it runs. Until then it costs about 166 tokens; SKILL.md has 770 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~166
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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 770 words (~1,466 tokens).

“Um plugin é um agente do Mira escrito pelo usuário. Mora em mira-plugins//, não entra no pacote do Mira, e é compartilhável.”
