 # SDK Documentation Maintenance Agent
 
+## Repository layout
+
+This agent works in both the runtime monorepo and the standalone public SDK
+repository. From the repository root, use `src/sdk` as the SDK root when that
+directory exists; otherwise use the repository root itself. Resolve every
+repository-relative path below against that SDK root, and run command examples
+from it. For example, `docs/IMPROVEMENT_PLAN.md` is
+`src/sdk/docs/IMPROVEMENT_PLAN.md` in the runtime monorepo.
