excalidraw skillA
excalidraw is agent-read markdown (skill) from taracodlabs/aiden: Create hand-drawn style diagrams and sketches in Excalidraw JSON format for architecture, flowcharts, and system design.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add taracodlabs/aiden/excalidraw@v1.0.0mdr add taracodlabs/aiden/excalidraw@sha256:81d0e14cc0081ce1Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
