1Excalidraw Diagramexcalidraw-diagram is an agent skill that instructs the model to author Excalidraw-compatible JSON diagrams which make visual arguments about workflows, system architecture, and abstract concepts. Solo builders use it when plain markdown fails to show causality, sequence, or ownership—common when documenting a micro-SaaS, agent pipeline, or integration map for future-you and collaborators. Before drawing, the skill directs a Depth Assessment and applies design philosophy: diagrams should argue, pass the Isomorphism Test (meaning visible without text), and the Education Test (teach concrete formats and real examples). All color and brand styling is centralized in `references/color-palette.md`, so indies can retheme once and keep outputs consistent across blog posts, pitch decks, and repo docs. Prism shelves it under Build → docs because deliverables are documentation files, but it is multi-phase: architecture diagrams during Validate scoping, launch narratives during distribution planning, and internal runbooks during Operate. Setup for local rendering is optional and documented in README.md; the core value is structured JSON the agent can iterate in chat-driven loops.5.2kinstalls
