Create or update architecture, infrastructure, deployment, swimlane, and request sequence diagrams as generated HTML pages with inline SVG and one PNG per diagram, in one fixed style with built-in layout checks. Use when the user wants to draw how an existing system, environment, pipeline, data flow, or request flow works for docs, a README, or a wiki, or to change, check, or render such a diagram or its diagrams.py; not for data charts or for designing a new system, which belongs to…
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
# Diagram Creation Diagrams are code. A project keeps one `diagrams.py` that defines its diagrams with the `diagram` package. One command checks every diagram against the layout rules, writes the HTML pages with inline SVG, checks in Chromium that all text fits, and writes one PNG for each SVG. The package fixes every color, font, and size, so all diagrams share one style. `D` is the diagram folder of the project, `docs/diagrams/` by default. ## 1. Decide whether to draw - Draw only when a reader learns more from the picture than from a paragraph or a table. A list of things is a table. A one-box diagram is a sentence. - Charts of data (bars, lines, scatter) are out of scope. - The best move is usually deletion. Each node is a distinct idea: merge two nodes that always travel together. Each arrow carries information: remove an arrow that the layout already shows. A diagram is done when nothing can be removed. Aim for a density of about 4 out of 10. ## 2. Set up the diagram folder 1. If `D` already has a `diagrams.py` and a `diagram/` package, use them. Follow the README or AGENTS.md in that folder. Those project rules override this skill. …

How to install
mdr add yarlson/yarstack/diagram-create@sha256:b8a91a8f329b4938The line at the top of this page pins the label git:20261105.9b1966a, 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.
