excalidraw SKILL.md skillA
excalidraw from nicholasspisak/excalidraw is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nicholasspisak/excalidraw/excalidraw@git:20260925.f581402Pins git:20260925.f581402 in mdr.lock. Pin the fingerprint instead.

Create and edit Excalidraw diagrams in an Excalidraw+ workspace — flowcharts, software architecture diagrams, sequence diagrams, data-flow diagrams, UML, Gantt charts, mind maps, wireframes, mockups, presentations/slide decks, roadmaps, user personas, brainstorming boards, Lean Canvas, SWOT analysis, competitor analysis, game-design boards, and whiteboarding-interview canvases. Use when asked to draw, diagram, sketch, wireframe, whiteboard, or make slides in Excalidraw.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Excalidraw
Author diagrams in an Excalidraw+ workspace through the official Excalidraw
MCP server (`https://api.excalidraw.com/api/v1/mcp`).
## Choosing a transport
1. **Native MCP tools first.** If this session exposes Excalidraw MCP tools
(e.g. `mcp__excalidraw__create_diagram`, or `excalidraw` tools in Codex),
use them directly.
2. **Bundled CLI otherwise.** If no native tools are available, use the
zero-dependency CLI in this skill (Node ≥ 18):
```bash
node scripts/excal.mjs tools # list tools
node scripts/excal.mjs help <tool> # print a tool's input schema
node scripts/excal.mjs call <tool> --json '{"key":"value"}'
```
Both paths hit the same server with the same tools — everything below
applies to either. (CLI examples are shown; substitute native tool calls
1:1.)
Auth: the CLI reads `EXCALIDRAW_API_KEY` from the environment (raw `sk-…` or
`Bearer sk-…` both work), falling back to `~/.config/excalidraw/api_key`.
If the key is missing the CLI prints setup instructions — relay them to the
user; never paste keys into files that could be committed.
## Core workflow
…Read the whole file at its exact version.
How to install
mdr add nicholasspisak/excalidraw/excalidraw@sha256:f5f70bef80927899The line at the top of this page pins the label git:20260925.f581402, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
