+# Agent Guide
+
+## Implementation priorities
+
+1. Keep the app simple for a 3-person internal team.
+2. Prefer server-rendered Django flows over heavy frontend complexity.
+3. Optimize for fast item creation and quick search.
+4. Preserve creator attribution on every item.
+5. Treat pricing integrations as advisory.
+
+## Working conventions
+
+- Update the docs whenever a workflow or model meaningfully changes.
+- Keep new fields aligned with the existing thrift-to-sale lifecycle.
+- Add focused tests for item creation, filters, and profit math before expanding the feature set.
