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, covering Slides and decks. It works with Canva. 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-transition-dissolve”
  • “transição dissolve”
  • “dissolve nos slides”
  • “/mira-transition-dissolve”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Bloco CSS do dissolve
  2. Helper dissolve e novo goTo
  3. Voltas ao topo também dissolvem

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 (its code samples are javascript and css).

    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 Transition Dissolve loads about 1.5k tokens when it runs. Until then it costs about 145 tokens; SKILL.md has 635 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~145
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 635 words (~1,477 tokens).

“Transforma a navegação card-a-card (scroll suave entre ) em dissolve: o slide se desmancha no próximo via crossfade. Mecanismo: View Transitions API same-document, que roda com clique duplo no file://`, sem servidor, em Chrome e Edge. Navegadores sem a API…”
