Learn how to design large-scale systems. Prep for the system design interview. Includes Anki flashcards. This page is an auto-generated, always-fresh map of the donnemartin/system-design-primer repository, written primarily in Python. Repowise indexes the source, parses every symbol, computes a dependency graph, scores per-file code health from complexity, duplication, test coverage and churn, mines git history for hotspots and ownership, and lifts the resulting architectural decisions into a wiki you can read or query through MCP.
The codebase has 51 source files, 209 symbols, and 4 languages, organised into 37 modules, led by python, markdown, yaml. Static analysis leaves 12 open findings across the three health dimensions.
Use the links above to open the interactive dashboards, or connect this repo to your editor via the Repowise MCP server for grounded answers inside Claude, Cursor, or VS Code.
