Generates a Mermaid class diagram showing types, inheritance, and composition. Use when visualizing class hierarchies or documenting a module public API.
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
# Class Diagram Generate a Mermaid class diagram showing types, their relationships, and public interfaces from a codebase. ## When To Use - Understanding class hierarchies and inheritance - Documenting public APIs of a module - Analyzing composition vs. inheritance patterns - Answering "what types exist and how do they relate?" ## When NOT To Use - Module-level imports (use `cartograph:dependency-graph`) - Runtime data movement (use `cartograph:data-flow`) ## Workflow ### Step 1: Explore the Codebase Dispatch the codebase explorer agent: ``` Agent(cartograph:codebase-explorer) Prompt: Explore [scope] and return a structural model. Focus on classes, dataclasses, protocols, type aliases, inheritance, and composition for a class diagram. Extract: class names, methods (public only), attributes, parent classes, and composed types. ``` ### Step 2: Generate Mermaid Syntax Transform the structural model into a Mermaid class diagram. **Rules for class diagrams**: - Use `classDiagram` diagram type - Show only public methods and key attributes - Use Mermaid relationship notation: - `<|--` for inheritance - `*--` for composition - `o--` for aggregation …

How to install
mdr add athola/claude-night-market/class-diagram@sha256:c6f87ec0354e8c1fThe line at the top of this page pins the label git:20260713.f98719b, 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.
