1Drawio Skilldrawio-skill is an agent skill aimed at solo and indie builders who need clear system diagrams, user flows, or integration maps while coding with Claude Code, Cursor, or Codex. Catalog metadata points at draw.io-style diagram work; when your repo’s SKILL.md defines triggers, follow those for install paths and file formats. Use it when a markdown spec is not enough and stakeholders need a visual model you can iterate in chat. It sits in the build docs lane as the primary shelf, but the same diagrams support validation conversations and launch explainers. Pair with planning or documentation skills so diagram labels stay aligned with your real components and APIs.1.3kinstalls2Creating Mermaid DiagramsCreating Mermaid Diagrams is a reference skill for solo builders who document systems in Markdown repos and want agents to emit valid Mermaid instead of broken diagram DSL. It covers class diagrams: members, methods, visibility prefixes, and the full relationship matrix from inheritance through realization, plus cardinality patterns on associations. ER diagram guidance shows entity blocks with typed columns, primary and foreign keys, and standard relationship connectors for orders, line items, and products. The content is syntax-first with minimal narrative, ideal when you are in Build writing technical docs, sketching a SaaS schema before migrations, or handing an agent a spec to visualize during Ship review. Because diagrams are declarative text, the skill pairs well with git-based docs and agent-tooling workflows without requiring shell or network access from the skill itself.729installs3ExcalidrawExcalidraw is an agent skill that teaches models how to emit correct Excalidraw JSON—rectangles, text labels, arrows, and bindings—so solo builders can produce architecture and workflow diagrams without opening a separate design tool first. The companion reference file is the long tail: copy-paste element templates, a standard file skeleton, and property catalogues when you need more than the core generate-time rules in SKILL.md. It fits indie teams who document systems in Excalidraw-compatible format from Claude Code or similar agents, especially when explaining auth flows, service boundaries, or onboarding sequences. Use it when you want consistent stroke colors, bound labels on shapes, and arrows that actually connect two components instead of floating loose coordinates. Outputs are plain JSON you can import or embed; complexity is intermediate because binding and boundElements must stay in sync across shapes.679installs4Plantuml SkillPlantuml-skill is an agent skill for solo builders who need diagrams that mirror what is actually in the codebase. Invoke it when someone asks for a class diagram of a module, a sequence diagram for a request handler, a component map from imports, an ER view from models or DDL, or a state chart from enums and transitions. The skill forces a read-first workflow: open the relevant files, list real types and edges, then emit PlantUML using the documented shape-to-syntax table. It is aimed at indie developers documenting APIs, onboarding themselves to unfamiliar folders, or preparing review artifacts without hand-drawing stale boxes. Because it spans documentation during build, pre-review clarity in ship, and mental models during operate iteration, it is tagged multi-phase with build/docs as the primary shelf—not a generic diagram chat prompt.621installs5Tldraw Skilltldraw-skill is an agent skill that turns natural-language requests into modern whiteboard diagrams. Solo and indie builders use it when stakeholders need flowcharts, architecture sketches, or relationship maps without opening a separate design tool. The workflow generates editable .tldr JSON and exports raster or vector assets locally through the tldraw CLI, which fits Claude Code, Cursor, and Codex sessions where the repo should own the artifact. Invoke it on explicit diagram requests or proactively when an explanation involves three or more components, non-trivial data paths, or spatial relationships that prose obscures. Compared with Mermaid-in-markdown, tldraw favors informal whiteboard styling and richer shape manipulation. Plan for Node.js, a global @kitschpatrol/tldraw-cli install, and optionally a vision-capable model for the documented self-check. Review Security Audits on the Prism detail page before trusting third-party CLI execution in CI or shared machines.583installs
