             ## Instructions
 
-            1. Diagnose why the build/lint/tests fail after the dependency bump
+            1. Analyze ALL the failure logs above to understand what broke
             2. Make the MINIMUM changes needed to fix it — do not refactor unrelated code
             3. Run `pnpm run build`, `pnpm exec eslint .`, `pnpm test:unit`, and `pnpm --filter @ably/react-web-cli test` to verify your fixes
             4. Commit your changes with a descriptive message
