     Invent defines the checks each Agent must pass before launch and samples live runs after deployment. When quality drops, it diagnoses the problem and proposes changes to prompts, Tools, examples, models, or orchestration. It can test those changes against the same requirements before you approve them.

     Invent reviews Agent activity, errors, Evals, and performance dashboards to diagnose problems and recommend improvements. Describe a recurring process, and it can help identify where Agents, Tools, or Workforces could automate it.

   <Accordion title="Project isolation">
     Invent's access to Relevance AI is scoped to the active project at the API-key and fine-grained authorization layers, not only in the interface. Each internal platform request uses the active project ID and the caller's API key, then passes through the standard authorization checks. Enabling Invent in a sandbox project does not grant it access to assets in a production project.

+  <Accordion title="Review and annotate a plan" icon="comment-lines">
+    When Invent generates a plan, you can select specific passages and leave inline comments, or add an overall note, before sending all feedback to Invent in one structured message.
+
+    #### Inline comments
+
+    Highlight any passage of text in the generated plan to open the comment input. Type a comment and confirm it — the comment becomes anchored to that specific passage. Anchored comments remain attached to their referenced text even if the plan is re-rendered or edited. Add multiple inline comments across different passages before sending.
+
+    #### Overall note
+
+    Use the overall note field for general remarks about the document as a whole — not tied to any specific passage.
+
+    #### Sending feedback
+
+    Click **Send feedback** to deliver all inline comments and the overall note to Invent as a single, structured message. Invent receives each comment with the exact passage it references, so it can precisely locate and address each piece of feedback. After sending, your feedback appears in the conversation history as formatted comment cards so you can review what was submitted.
