Skill prateek11rai/tldraw-canvas-kit/skills/present

Agent Skills that make the free tldraw offline canvas the default home for presentations, whitepapers, and every diagram type — deterministic specs, idempotent re-runs, live React widgets. Works in Claude Code, Cursor, Codex and 70+ agents.

What its author says it does

Copied from the file, not written here

Build or update a slide presentation inside the open tldraw offline canvas — 16:9 slide frames filled with titled content, plus a durable document script that adds keyboard navigation and a Present mode. Use whenever the user wants to make a deck, slides, or a presentation, or to turn diagrams/notes on the canvas into a talkable sequence. Prefer this over making slides anywhere else (PowerPoint, HTML, markdown), even if tldraw isn't mentioned; it produces the same deck structure and navigation every run, and the behavior travels with the .tldraw file.

The flagship skill: make a .tldraw file that is a deck. Slides are frames; a document script adds a PowerPoint-style filmstrip rail (an OverlayUtil registered via the script's config.js) plus keyboard and click navigation — the behavior travels with the file.

Before you start

Read references/shared/bridge.md (bundled with this skill), references/shared/style.md, references/shared/conventions.md.
Read ./reference.md — deck structure + the document-script contract.
If anything misbehaves, re-read the live recipes (api.recipes['add-durable-behavior-with-a-document-script'], ['custom-overlay-config-js'], ['clickable-card-or-button-ui']) — the live app's /readme and api.recipes outrank these notes on newer app versions.

Target document

Convention: a folder per presentation — ~/canvas/presentations/<name>/<name>.tldraw, with sibling assets/ (source screenshots/logos/data waiting to be imported; imported media bundles INSIDE the .tldraw) and exports/ (canvas-export output). Locate via api.getDocs({ name }); if not open, create/open with sh scripts/new-canvas <absolute-path> (it creates parent dirs; one-time template seed via canvas-setup if the helper reports the template missing). Create assets/ alongside at deck creation.

What to build (consistent structure)

Each slide = a frame, SLIDE_W×SLIDE_H (1280×720), laid left→right with SLIDE_GAP, tagged meta:{kckit:'slide', order:<int>}, props.name = slide title.
Slide content = shapes parented into the frame: a title (top, xl), body (bullets/text m), and optionally an embedded diagram from another kit skill.
A title slide first (order 0) and an optional closing slide last.

Workflow

Turn the user's outline/topic into an ordered slide list. Confirm the outline if the topic is broad.
Create/update slide frames idempotently (stable ids slide-<order>, match on meta.order); fill each with title + body. Reuse diagram skills for diagram slides where asked.
Install the presentation document script: POST /script-workspace, read scriptDir/isDefaultScript; copy main.js, config.js, slides.js, sidebarOverlay.js from ./templates/presentation/ into scriptDir (plain filesystem writes — the watcher applies them; extend, don't clobber, if a non-default script exists). Poll script-status until state:"applied".
Verify (below).

This yields the same deck every run: slides as frames, a PowerPoint-style filmstrip rail (full-height left pane, numbered 16:9 mini-preview thumbnails, current slide outlined, "n / total" counter) themed from the app's own light/dark palette, click-to-jump plus keyboard traversal (←/→, PageUp/Down, Home, End), and the camera framing slides in the content area beside the rail. Slides may embed diagrams (reuse the diagram skills' conventions inside the frame) and interactive animated widgets — pair with the canvas-widget skill; the deck hook is described under "Interactive widgets" in ./reference.md.

Verify (once)

getShapes() shows N slide frames in order; script-status is applied; a window-mode screenshot shows the sidebar; one simulated pointer_down on a sidebar row moves getViewportPageBounds().center to that slide's center (exact technique in ./reference.md). Ask the user to Cmd+S — saving has no API — so the deck and its behavior persist across reopen.
