Use when producing a diagram as a .excalidraw file, or when asked for an architecture, flow, sequence, tree, mind map, org chart, timeline, network, ERD, swimlane, kanban or wireframe drawing that should look hand-drawn. Writes a short spec and expands it deterministically with measured font metrics, real layout and correct arrow bindings, then lints and renders it. Triggers on excalidraw, diagram, sketch, whiteboard, architecture diagram, flowchart, sequence diagram, mind map, hand-drawn, and…
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 diagrams ## The contract **Write a spec. Never write `.excalidraw` JSON by hand.** A spec of 20 to 60 lines becomes hundreds of lines of correct JSON, and the three things a model is worst at are done by code instead: | Problem | Why hand-writing fails | What does it here | |---|---|---| | Coordinates | Placing boxes is arithmetic, and the failure is visible: overlapping nodes, arrows through shapes | A layout pass with deterministic tie-breaks | | Text width | **Excalidraw never re-measures text on open.** `restoreElements` runs without `refreshDimensions`, so a wrong stored width silently clips glyphs | Advance widths measured in a browser against the real fonts | | Invariants | Most violations open fine and look wrong, so nothing tells you | A linter that runs before you look | ```bash S=~/.claude/skills/excalidraw/scripts python3 $S/exdraw.py mydiagram.yaml -o mydiagram.excalidraw # build python3 $S/exlint.py mydiagram.excalidraw # MANDATORY, before looking python3 $S/exfidelity.py source.mmd mydiagram.excalidraw # only when redrawn from Mermaid python3 $S/exsvg.py mydiagram.excalidraw -o preview.svg # deterministic preview …

How to install
mdr add plexito-de/honed-skills/excalidraw@sha256:bc4dfb0b61e40e13The line at the top of this page pins the label v1.2.0, 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.
