One Index: The Case for Shared Code Intelligence
· 7 min read
Your codebase has one architecture. Why does every developer's AI agent build its own private mental model of it?
The last few posts in this series have focused on what goes into an AI agent's context window: why structural code intelligence beats text search, how Code Mode collapses multi-step queries into a single efficient round-trip, and how plugins encode team knowledge as reusable primitives. But most AI coding tooling shares a quiet assumption: code intelligence is a per-developer artifact. Every engineer builds their own snapshot of the codebase and queries it alone.
That model made sense when AI coding tools were still finding their footing. For teams working on serious codebases, it's starting to show its limits.
