Generate C4 architecture diagrams as GitHub-renderable Mermaid, and PowerPoint slides. Use to update docs, or draw a c4 diagram, flowchart, sequence diagram, org chart, timeline or mind map.

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

# Documentation & Diagrams Skill

When the user asks about creating architecture documentation, C4 models, PowerPoint presentations, or visual content for slides, use the commands below.

- **PowerPoint/PPTX** is generated by the native Anthropic `pptx` skill (install with `npx skills add anthropics/skills@pptx`) - not an MCP server.
- **C4 diagrams** are rendered as GitHub-renderable Mermaid by a zero-dependency Python engine (`scripts/c4-mermaid.py`, issue #411): L1-L3 as `flowchart` with `subgraph` boundaries, L4 as `classDiagram`. Output is `.mmd` files plus an `index.md` that renders inline on GitHub.

## Quick Reference

### Commands

| Command | Purpose |
|---------|---------|
| `/documentation:c4` | Generate C4 architecture diagrams (all 4 levels) |
| `/documentation:pptx` | Guided PowerPoint creation with diagrams |
| `/documentation:help` | Overview of documentation commands |

### C4 Diagram Workflow

1. Analyze project (CLAUDE.md, README, directory structure)
2. Build a C4 model (`docs/architecture/c4-model.json`) for the 4 levels: L1 Context, L2 Container, L3 Component, L4 Code

How to install

The exact contents, by fingerprint

mdr add cooneycw/claude-power-pack/documentation@sha256:7e43b85b820e49a1

The line at the top of this page pins the label git:20260920.677b300, 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.
