Work with .excalidraw and .excalidraw.json diagrams, including reading, explaining, comparing, creating, and editing them. Use context-isolated native agents for JSON-heavy operations when available, with a bounded sequential fallback when delegation is unavailable.
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 Context-Isolated Operations Excalidraw JSON has high token cost and low semantic density. Keep raw element metadata out of the main conversation when possible, but do not make delegation a prerequisite for completing the task. ## Role Contract Choose the role by side effect, not by a vendor-specific tool name. | Operation | Semantic role | Contract | |-----------|---------------|----------| | Read, explain, compare | Read-only explorer | Read target diagrams; return only labels, relationships, and evidence. Do not write files. | | Create, modify | General writer | Own only the designated output files; preserve unrelated elements; validate written JSON; report changed paths and checks. | Use the current CLI's built-in explorer or general worker that satisfies the contract. Do not require a custom agent name or assume a particular `Task`/spawn argument schema. The main context owns scope, acceptance criteria, final verification, and the user-facing explanation. If native delegation is unavailable or fails, perform the same operations sequentially in the main …

How to install
mdr add dannykkh/skill-olympus/excalidraw@sha256:93ace3f3e8fa1152The line at the top of this page pins the label git:20260812.afc9950, 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.
