FAQ

What did ArcSight find in LangChain.js (libs/langchain-core)?
LangChain.js (libs/langchain-core) has 248 modules and an architecture score of 66.4/100.
Why does the LangChain.js (libs/langchain-core) structure matter?
The LangChain.js (libs/langchain-core) score is 66.4/100 across 248 modules and 973 edges.
Which file should I inspect first in LangChain.js (libs/langchain-core)?
Start with src/messages/content. Run arc impact on that file before the change merges.

Key takeaways

  • •Structural scan reports dependency cycles — inspect impact paths before refactors that cross module boundaries.
  • •High fan-in modules are change-risk zones; run arc explain <path> before refactoring.
  • •Run the full workflow (analyze, hotspots, explain, impact, snapshot, drift) in your repo for deterministic architecture insights.
