Generate or update an interactive architecture diagram from a codebase — one self-contained HTML file with C4-style drill-down levels, pan and zoom, an inspector, and a step-through player for runtime flows. Use this whenever someone wants to see, draw, map, visualise or document how their code fits together — 'diagram my codebase', 'show me the architecture', 'how does a request flow through this', 'make me a C4 diagram', 'something like IcePanel or Structurizr', or asks to refresh an…
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
# draw-c4 — interactive C4 architecture diagrams
Turns a codebase into an explorable diagram: a single HTML file with no build step
and no dependencies, holding up to four levels of detail and a set of animated
runtime flows.
## Find the skill directory first
**Do this once, before any other step.** This skill's files sit wherever it was
installed, which is never the user's working directory. Resolve that location and
use absolute paths from then on — bare relative paths like `scripts/plot.py` will
not resolve:
```bash
SKILL="$(dirname "$(dirname "$(find "${CLAUDE_PLUGIN_ROOT:-/nonexistent}" \
~/.claude/skills ~/.agents/skills "$PWD/.claude/skills" \
-name plot.py -path '*draw-c4*' 2>/dev/null | head -1)")")"
```
That covers every install route — plugin, `npx skills`, and a hand-copied skill
folder at user or project level. Sanity-check it resolved:
```bash
ls "$SKILL/scripts/plot.py" "$SKILL/assets/plot-template.html"
```
Every command below writes `"$SKILL"` for that directory. Keep the quotes; the
path can contain spaces. Read the bundled reference files by absolute path too —
`$SKILL/references/model-schema.md`, `$SKILL/assets/example-model.json`.
…Read the whole file at its exact version.
How to install
mdr add shibainu0817/draw-c4-skill/draw-c4@sha256:5619dbdb2d4c5908The line at the top of this page pins the label git:20261027.bb3fdce, 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.
