Draw architecture, sequence, flowchart, or ER diagrams as code with the D2 CLI. Use when the user wants to create, edit, validate, or render any diagram or .d2 file.

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

# D2 — Diagrams as Code

> **Manual only** — invoke explicitly with `/skill:d2`; the agent won't reach for it on its own.

D2 turns text into diagrams. **Knowledge skill** — the agent drives the `d2` CLI directly; `scripts/` only adds thin wrappers. Requires `brew install d2`.

> **Ecosystem:** hand-drawn presentation figures (sketchy look, manual layout) → **`figure`** ·
> shareable page/report (one HTML + URL) → **`visualize`** · `d2` = auto-laid-out technical
> diagrams (sequence, ER, class, many types) with ASCII self-verification.

## Install

```bash
openskills install devskale/skale-skills/skills/d2   # → pi, claude, opencode, …
```
Or clone + add to pi config: `"skills": ["~/code/skale-skills/skills/d2"]` in `~/.pi/agent/settings.json`.

## Quick Start — the render loop

```bash
bash scripts/d2v diagram.d2          # ONE command: validate → ASCII to stderr → svg → width-bloat check
bash scripts/d2v diagram.d2 -- --sketch --theme 4   # forward flags to d2 (sketch/themes — sketch is CLI-only, vars ignore it)
bash scripts/d2png diagram.d2        # PNG via rsvg-convert (no Playwright/Chromium download)
# (the raw loop it runs, if you need the pieces:)
…

How to install

The exact contents, by fingerprint

mdr add devskale/skale-skills/d2@sha256:c4d1fe82009bc7cc

The line at the top of this page pins the label v1.4.1, 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.
