-The second `provideAgent()` isn't a duplicate. Angular's hierarchical DI merges it with the root provider from Step 2: `apiUrl` comes from the root, `assistantId` and `threadId` come from this component-level call. Splitting config this way lets one app host several `<chat>` surfaces that share a backend URL but target different graphs. See the [Multiple agents](/docs/chat/getting-started/installation) note in Installation for the full pattern.
+`injectAgent()` returns the singleton wired up in Step 2 — no extra provider needed here. To host several `<chat>` surfaces that share a backend URL but target different graphs, re-provide `provideAgent({...})` in a component's `providers: []` array; Angular's hierarchical DI scopes that override to the subtree. See the [Multiple agents](/docs/chat/getting-started/installation) note in Installation for the full pattern.
