What it does

Superdeck Presentations is an agent skill from btwld/superdeck. Create, review, or edit SuperDeck Markdown presentations and Flutter presentation apps. Use for slides.md layouts, images, custom widgets, DeckOptions styling and templates, or verifying a rendered deck.

Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `references/authoring.md` and `references/runtime-customization.md`).

It sits in Documents & Office, covering Slides and decks and Cross-platform mobile apps. It works with Flutter. The repository describes itself as: Presentation slides for Flutter with Flutter. The licence is BSD-3-Clause.

When your agent uses it

  • Slides.md layouts
  • DeckOptions styling and templates
  • Verifying a rendered deck

Example prompts

  • “/superdeck-presentations”

What it can do on your machine

Read from SKILL.md and the folder at commit 815a746. 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

Superdeck Presentations loads about 649 tokens when it runs, and up to ~8.9k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 277 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~649
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.9k

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.

SuperDeck Presentations

Use Markdown to compose slides and Dart to configure presentation styles, parts, widgets, and templates. Inspect the existing deck and app before changing either.

Read for the task

  • Authoring: slides.md syntax, layout, images, Markdown, and built-in widgets.
  • Runtime customization: app setup, DeckOptions, styles, templates, parts, custom widgets, assets, and plugins.
  • Verification: build and visual checks before claiming a deck works.

Layout and styling model

  • Slides use a logical 1280 × 720 canvas. @section rows stack vertically; their child blocks and widgets form horizontal columns. Positive integer flex values divide height between sections and width between children.
  • Use standalone Markdown images in content flow and @image for a dedicated visual with fit, dimensions, or block layout controls. scale changes painting within the image frame, not its layout size.
  • Effective content alignment is block align → section align → centerLeft.
  • Section spacing creates gutters between child blocks. Block margin reduces space inside that block's allocated frame, outside its decoration; padding is inside the decoration. Use section spacing for shared gutters.
  • SlideStyler controls headings, paragraphs, inline emphasis and links, and slide styling. Its blockContainer takes BlockStyler; BlockVariant('name') selects an exact, case-sensitive widget-block name, including built-ins such as @image, never Markdown @block content.
  • scrollable is valid on @block and widget blocks, not on @section.
  • Frontmatter style and template select named styles and templates registered in Dart. layout: fullscreen removes header and footer while preserving the resolved background and style.
  • Register custom widgets in DeckOptions.widgets before using their names as Markdown directives.

Examples and source of truth

For a complete visual example, see the layout showcase deck and its Dart styles. For exact syntax and behavior, consult docs/tutorials/block-layouts.mdx, docs/reference/deck-options.mdx, and the parser/rendering code.
