Right, the raw material is there — but there's a gap between "data exists" and "agent has a working model of it." Reading git history on demand is retrieval; internalizing which patterns the team consistently rejects, which abstractions they've refactored away from twice, which reviewer will push back on X — that's a different thing.

The analogy is a new hire with full access to the wiki and Slack history vs. someone who's been on the team six months. The new hire can look things up; the veteran has already synthesized it into judgment that fires before they write a line. Agents currently operate like very fast new hires — great at retrieval, weak on the accumulated synthesis.
