architecture-diagramming from sigistry/marketplace is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add sigistry/marketplace/architecture-diagramming@git:20260826.571bc2fPins git:20260826.571bc2f in mdr.lock. Pin the fingerprint instead.

This skill should be used when the user asks to "generate architecture diagrams", "create dependency graph", "draw sequence diagram", "visualize system architecture", "C4 model", "Mermaid diagram", "component diagram", "ER diagram", or "data flow diagram". Provides C4 model methodology and Mermaid diagram templates for architecture documentation.
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
# Architecture Diagramming ## Purpose Provide standardized methodology and templates for generating architecture diagrams from codebase analysis. Uses the C4 Model for hierarchical architecture views and Mermaid for diagram rendering. ## C4 Model Overview The C4 Model defines four levels of architecture abstraction: | Level | Name | Shows | When to Use | |-------|------|-------|-------------| | 1 | System Context | System + external actors | Always, the "big picture" | | 2 | Container | Applications, data stores, services | When multiple deployable units exist | | 3 | Component | Internal modules within a container | When analyzing a specific service | | 4 | Code | Classes, interfaces | Rarely, only for critical components | ## Diagram Selection Guide Choose diagrams based on what exists in the codebase: | What You Find | Diagrams to Generate | |---------------|---------------------| | Multiple services/microservices | System Overview (L1), Container (L2), Dependency Graph | | Database schemas/models | ER Diagram | | API endpoints | API Interaction Diagram | | Message queues/events | Event Flow Diagram | | Multi-step workflows | Sequence Diagrams | …

How to install
mdr add sigistry/marketplace/architecture-diagramming@sha256:32333d96ee742595The line at the top of this page pins the label git:20260826.571bc2f, 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.
