System design from evidence, not vibes — reads your repo as the current architecture, runs the capacity math, compares structurally distinct candidates, and ships an interactive report. For Claude Code, Codex, Cursor, and other coding agents.
These files are pinchen147/system-design-skill's own configuration. They tell Codex, OpenCode and Claude Code how to work on this repository, so they are not mods to install elsewhere. Copy one as a starting point and replace the parts that are about this project.
