AI-orchestrated visual canvas production — create, populate, layout, present, generate, and export Obsidian canvases

Content strategist for canvas text nodes. Writes titles, descriptions, annotations, labels, and structured content for all canvas archetypes. Follows the 15-30 visible nodes per viewport principle. Content is scannable: headers, bullets, bold. Max 200 words per text node. <example>Context: /canvas generate needs slide content for a 6-slide presentation assistant: Dispatches canvas-composer to write all slide text</example> <example>Context: /canvas generate "dashboard for project status" needs metric cards assistant: Agent writes structured metric card content with KPI values</example>

Spatial positioning specialist for Obsidian Canvas. Computes optimal node positions using layout algorithms (dagre, grid, radial, force-directed, linear). Preserves zone containment, snaps to 20px grid, refits groups. Dispatched for complex canvases with 30+ nodes requiring multi-zone layout or algorithm selection refinement. <example>Context: User runs /canvas layout dagre on a 40-node flowchart assistant: Dispatches canvas-layout agent for complex positioning</example> <example>Context: User runs /canvas layout auto and content spans multiple zones assistant: Agent analyzes each zone independently, applies best algorithm per zone</example>

Media asset dispatcher for canvas generation. Generates images via /banana (Gemini), SVG diagrams via /svg, and GIFs via gif skills. Returns file paths for placement on canvas. Handles batch generation for multi-image canvases. <example>Context: /canvas generate needs 4 AI images for a mood board assistant: Dispatches canvas-media agent to batch-generate via /banana</example> <example>Context: /canvas generate needs a flowchart SVG and 2 hero images assistant: Agent generates SVG via /svg, then images via /banana</example>

Create new Obsidian Canvas files — blank with a starter structure, or from one of 12 template archetypes (presentation, flowchart, mind-map, gallery, dashboard, storyboard, knowledge-graph, mood-board, timeline, comparison, kanban, project-brief). Handles directory creation, slug generation, and starter zone setup. Triggers on: canvas create, create canvas, new canvas, canvas new, start canvas.

Export Obsidian Canvas files to PNG, SVG, or PDF formats. Uses the Advanced Canvas plugin's built-in export when Obsidian is running, or falls back to Playwright browser-based screenshot capture. Supports single canvas export, presentation slide-per-page PDF export, and batch export. Triggers on: canvas export, export canvas, canvas to png, canvas to pdf, canvas to svg, save canvas as image, screenshot canvas, export presentation.

AI-orchestrated full canvas generation. Given a description, detects the best archetype, generates content and visuals, instantiates a template, applies layout, and produces a complete canvas. The flagship command. Dispatches canvas-media and canvas-composer agents for parallel asset generation. Triggers on: canvas generate, generate canvas, create a visual board, build me a canvas, make a canvas about, canvas from description, auto-generate canvas, full canvas generation.

Re-layout existing Obsidian Canvas nodes using 6 spatial algorithms: grid (galleries, mood boards), dagre (flowcharts, org charts), radial (mind maps), force-directed (knowledge graphs), linear (timelines), and auto-detect. Preserves group membership, snaps to 20px grid, refits zones around content. Triggers on: canvas layout, re-layout canvas, arrange canvas, auto-layout, organize canvas, fix canvas layout, canvas grid, canvas dagre.

Add content to existing Obsidian Canvas files. Supports all node types: images (with auto aspect ratio detection), text cards, PDFs, wiki notes, web links, Mermaid diagrams, SVGs, GIFs, AI-generated images via banana. Also adds zones (groups), edges between nodes, and imports recent banana images. Triggers on: canvas add, add to canvas, put on canvas, canvas zone, canvas connect, canvas from banana, add image to canvas, add text to canvas.
