Generate modern reviewable diagrams (system architecture, workflow, data flow, sequence, ER, state-machine, C4) via OpenRouter image-gen or LLM-emitted SVG. Auto-classifies diagram type from prompt; --type to override. Default scratch output goes to the resolved workbench visuals path; --versioned writes git-trackable specs and variants under docs/diagrams/.

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

# vd:diagram

Turn natural-language descriptions into reviewable diagram images and version-controlled diagram artifacts. Two render paths:
- **PNG** (default): generates the image. Default image provider is **codex** (`gpt-image-2` via your ChatGPT subscription - cost-optimized, no per-image API spend), with automatic fallback to OpenRouter `gpt-5.4-image-2` when codex is unavailable and an OpenRouter key is set. Force the API path with `--provider openrouter`. With `--provider codex` and an explicit `--type`, no `OPEN_ROUTER_KEY` / `OPENROUTER_API_KEY` is required.
- **SVG** (`--format svg`): the LLM emits the SVG markup directly. Cheaper, crisper labels, hand-editable.

Use `--versioned` only when the diagram source, variants, and manifest are themselves review artifacts for an ADR/spec/PR. It writes a stable folder under `docs/diagrams/<slug>/` with:
- `diagram.spec.yaml` - reviewable source intent (type, preset, engine, description, latest variant)
- `manifest.json` - deterministic metadata for automation
- `v1.svg`, `v2.svg`, ... or `v1.png`, `v2.png`, ... - rendered variants
…

How to install

The exact contents, by fingerprint
mdr add vanducng/skills/diagram@sha256:bfde541f9aabf0eb

The line at the top of this page pins the label v1.0.1, 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.
