The Data Context Layer for Agents — Yoni Michael & Brandon Callender, Typedef
Two Rust types are both called PostingList, but changing them breaks different code.
Proof1 independent outlet
Key points
- A text search finds both; a context graph preserves their identities and exposes their separate dependencies.
- Michael describes a context layer that computes grain, lineage and relationships from transformation code, checks join assumptions against real data, and makes the resulting evidence queryable before an agent acts.
- Tree sitter extracts syntax, Rustdoc resolves symbols, and Neo4j stores the relationships.
