What do you make of this discussion? Particularly the top comment: https://news.ycombinator.com/item?id=47367129. Would that be something you could incorporate into this project, the idea of a semantic index?
Interesting discussion. The core idea is that instead of stuffing everything into context, you build per-file semantic summaries (function descriptions, type signatures, usage guidance) that are cached until files change, then use those summaries to intelligently select only the relevant code/content for each request.
Let me explore how this might apply to your project — you already have a RAG pipeline and content embedding system, so there may be a natural fit.
Good clarification — so the idea is a semantic index of this codebase (the TypeScript/Next.js monorepo code) to help AI coding tools like Claude Code work more effectively with it, rather than something for the course content RAG pipeline.
The project already has a pretty comprehensive CLAUDE.md with architecture docs, and the memory system persists context across conversations. A semantic index would add a more granular, auto-generated layer — per-file or per-module summaries of exports, types, function signatures, and usage patterns that stay current as code changes.
Before I plan this out, let me clarify a few things:
Great — so this is a tool for me to use. Let me think honestly about what would actually help me most when working on this codebase, and plan accordingly.
Got it — this is a tool to help me help you better. Let me read a few key files to validate the plan's assumptions, then write it up.
Good — I can see the export patterns. Packages use both export * from (types) and explicit named exports (llm). Now let me write the plan.
