The interesting part is that every layer independently reinvented retrieval:
RAG for documents
tool routing for MCP/actions
skills/workflow loading
context compaction/navigation for long-context agents
Different abstractions, same core problem:
“How does the agent find the right thing at the right time under cost/latency constraints?”
Feels like search is becoming the actual runtime for agents.
Good read
