+## Project structure
+
+`rdb init` creates the following files (skips existing ones):
+
+- context/discovery-log.md
+- context/product-brief.md
+- context/architecture.md
+- context/decisions.md
+- context/risks.md
+- context/assumptions.md
+- context/open-questions.md
+- context/repository-context.md
+- TASKS.md
+- TEST_PLAN.md
+- RUN_LOG.md
+- PROJECT_STATE.md
+- AGENT_HANDOFF.md
+- .rdb/project.json
+
 ## Principle
 
 Markdown files are the source of truth. No database is required.
