+description: Consult the graphify knowledge graph at graphify-out/ for codebase and architecture questions.
+---
+
+## graphify
+
+This project has a graphify knowledge graph at graphify-out/.
+
+Rules:
+- For codebase or architecture questions, when `graphify-out/graph.json` exists, first run `graphify query "<question>"` (CLI) or `query_graph` (MCP). Use `graphify path "<A>" "<B>"` / `shortest_path` for relationships and `graphify explain "<concept>"` / `get_node` for focused concepts. These return a scoped subgraph, usually much smaller than `GRAPH_REPORT.md` or raw grep output.
+- If graphify-out/wiki/index.md exists, navigate it instead of reading raw files
+- Read graphify-out/GRAPH_REPORT.md only for broad architecture review or when query/path/explain do not surface enough context
+- After modifying code files in this session, run `graphify update .` to keep the graph current (AST-only, no API cost)
