+# Organism Architect
+
+When to use this skill
+
+- Use when creating page sections that aggregate molecules and small stateful interactions.
+- Triggered by prompts to scaffold feed components, lists, or composite UI patterns.
+
+Instructions
+
+1. First Step: Design the organism's responsibilities (data fetching vs. purely presentational) and choose which molecules it composes.
+
+2. Second Step: Implement the organism under `src/components/organisms/`, use hooks for data and local UI state, and expose minimal props for customization.
+
+3. Third Step: Add skeletons or loading states (spinners/skeleton cards) and tests verifying interactions and accessibility.
+
+Examples
+
+- PaperFeed: fetches a list of papers via `useArXivFetch`, renders `PaperCard` molecules, supports infinite scroll or pagination.
+
+Notes
+
+- Keep organisms at the page level; avoid adding global app logic here—use stores or modules for cross-cutting concerns.
