+description: Use when the user asks to update, upgrade, or refresh project dependencies, or when outdated dependencies need attention

+
+# Update Dependencies
+
+## Workflow
+
+1. Run `mise run dev:outdated` to check all dependency categories
+2. Read the summary table at the end of the output — it has three columns: Dependency, Status, and Next Step
+3. For each row marked as outdated, run the command listed in the Next Step column
+4. Re-run `mise run dev:outdated` to confirm everything is up to date
+5. Run `mix test` to verify nothing is broken
