3. Agentic RAG: Adaptive Retrieval with Agents & Memory
Why it matters
Provides blueprint for production RAG upgrades with agentic decision-making, applicable in TS via libraries.
Key takeaway
Agentic RAG improves on this by introducing AI agents that can make decisions, select tools, and even refine queries.

4. Production Agent Drifts: Daily Maintenance Realities
Why it matters
Emphasizes need for observability and evals in prod agents, key for reliable AI UX in JS products.
Key takeaway
We now spend 15 minutes a day maintaining each of our AI agents. Without that daily maintenance, agents drift.

5. Coding Agents Excel at Large Production Codebases
Why it matters
Validates agents for real-world JS/TS codebases, accelerating prod maintenance with structured context.
Key takeaway
I don't think that idea holds up any more
