change-coupling

Find the files to refactor first: hotspots (change frequency × complexity), bus factor and change coupling from your git history. One npx command, offline, any language.

Catch the files you — or your AI agent — forgot to change. Learns from git history, warns before commit. MCP server + CLI.

Flags the files you forgot to change, learned from your git history. Backtested on your own repo. Works as a CLI, CI annotation and coding-agent hook.

See which files secretly change together before your refactor breaks them. Local git-history heatmaps, force graphs, and JSON.
