Use when user requests diagrams, flowcharts, architecture charts, or visualizations. Also use proactively when explaining systems with 3+ components, complex data flows, or relationships that benefit from visual representation. Generates .excalidraw files and exports to PNG/SVG via Kroki API or locally using excalidraw-brute-export-cli.

Prompt

After creating an initial diagram.excalidraw JSON file, we want to visually inspect it for clipped text and arrow collisions before sharing. Which exact local CLI command converts diagram.excalidraw to a 2x PNG file named /tmp/check.png with background baked in?

What was checked, without and with the skill

Excalidraw Diagrams

Overview

Generate .excalidraw JSON files and export to PNG/SVG.

Two export options:

Kroki API (curl) — zero install, SVG output only
excalidraw-brute-export-cli — local Firefox-based, PNG + SVG

Supported formats: PNG (local CLI only), SVG (both options). PDF is NOT supported.

When to Use

Explicit triggers: user says "画图", "diagram", "visualize", "flowchart", "draw", "架构图", "流程图"

Proactive triggers:

Explaining a system with 3+ interacting components
Describing a multi-step process or decision tree
Comparing architectures or approaches side by side

Skip when: a simple list or table suffices, or user is in a quick Q&A flow

When NOT to use it — route elsewhere:

Polished, precise diagrams, strict UML, or branded vendor icons → drawio.
Diagrams-as-code in git, auto-laid-out from text → mermaid (general) or plantuml (UML).
An infinite-canvas whiteboard or programmatic freehand strokes → tldraw.

Prerequisites

Option A: Kroki API (recommended — zero install, SVG only)

# Just needs curl (pre-installed on macOS/Linux/Windows Git Bash)
curl --version

No additional setup. SVG rendered via https://kroki.io.

Option B: Local CLI (required for PNG)
