# Tech Graph Generate publish-grade technical diagrams as SVG first, then PNG when raster export is needed. This is a helper skill only. - Do use it for architecture diagrams, data flow diagrams, flowcharts, sequence diagrams, state machines, ER diagrams, use-case diagrams, timelines, and comparison matrices that should become durable artifacts. - Do use it when the output should live under `process/general-plans/references/`, `process/general-plans/reports/visuals/`, `process/features/{feature}/references/`, or `process/features/{feature}/reports/visuals/`. - Do use `preview` after generation when you want explanation, HTML framing, Mermaid review, or visual self-check of the finished artifact. - Do not use it as a plan or execution workflow. - Do not use it to replace inline doc diagrams when a lightweight Mermaid or ASCII explanation is enough. ## Capability Surface The local skill now includes upstream-style assets: - 7 visual style references - style-to-diagram guidance matrix - icon and SVG layout reference material - reusable SVG templates - JSON regression fixtures - template-driven generation script - batch style validation script Load the smallest references that fit the request: - `references/style-diagram-matrix.md` to choose a style and diagram family - `references/style-1-flat-icon.md` through `references/style-7-openai.md` for exact visual language - `references/icons.md` for semantic shapes and product-icon guidance - `references/svg-layout-best-practi...
