diagram

v2.2.2

Architecture / flow diagram authoring — turn a spec or raw code into a readable, clickable diagram (classes with methods, objects, permission sets, relations) rendered as one browsable HTML page under docs/diagrams/<name>/. Builds a <name>.diagram.json model laid out with React Flow + ELK (elkjs), hardened by parallel Sextant reviewer agents over a capped review loop.

Included Skills1

diagramskills/diagram/SKILL.md

Use when asked to draw, sketch, map, diagram, visualize, or make a picture/schema/architecture of how software works — the architecture or how-it-works view of a feature, the relationships between classes or interfaces (with their methods and fields), data or record flow, an object model with its fields and permission sets, or a dependency graph — for a package, a feature, a handful of files, or a whole undocumented source directory, built from a spec, a plan or ticket, or read straight from the code, and output as one shareable HTML page you can commit. Also use to clean up an existing generated diagram that is hard to read (overlapping nodes, tiny text). Do NOT use to plot a data or metrics chart from a dataset, to paste a mermaid or ascii snippet into a PR or README, to draw in an external editor like Lucidchart or Excalidraw, to convert a whiteboard photo, to re-render an existing page for a screenshot, or to explain how something works in words with no picture.
