<Check>
  **Level 1 complete!** You've built a working agent from scratch. It answers questions, speaks with a voice you chose, and is safely versioned across environments.
</Check>

You can now answer these questions without guessing:

* Why did the agent respond that way?
* Which topic or rule was responsible?
* How do I change this behavior safely?
* How do I verify the change worked?

## Level 1 recap quiz

<Quiz
  questions={[
{
q: "You created a topic called 'help' with good content, but it triggers for almost every user question. What went wrong?",
options: [
  "The content is too long",
  "The topic name is too generic – it matches too many intents",
  "The sample questions are too specific",
  "The voice settings are misconfigured",
],
correct: 1,
explanation: "The topic name is the strongest signal for retrieval. A name like 'help' is too broad and will match almost everything. Rename it to a specific, single-intent name like 'parking_policy' or 'check_in_time', then re-test to confirm it only triggers for the intended question.",
},
{
q: "You edited a topic, published the change, and promoted to Sandbox – but the agent still gives the old answer. What should you check next?",
options: [
  "Whether you're testing against the correct environment (Sandbox, not Live)",
  "Whether the voice model needs reloading",
  "Whether the agent's personality overrides topic content",
  "Whether you need to restart the project",
],
correct: 0,
explanation: "If the change is published and promoted, the most likely issue is testing the wrong environment. Confirm you're calling the Sandbox number or chatting in the Sandbox context – check the environment selector in Conversation Review to verify.",
},
{
q: "In Conversation Review, the matched topic is correct but the agent's answer is wrong. Where is the problem?",
options: [
  "The topic name needs changing",
  "The sample questions are wrong",
  "The topic content needs updating – the right topic triggered but the answer text is incorrect",
  "This is an ASR error",
],
correct: 2,
explanation: "If the right topic triggers but the answer is wrong, the issue is in the topic's content field – not its name or sample questions. Open the topic, update the Content text, publish, and re-test.",
},
{
q: "Before promoting a version from Sandbox to Pre-release, what is the most important safety step?",
options: [
  "Notify your team that a promotion is happening",
  "Compare versions to confirm all changes are intentional",
  "Update the publish note with a summary",
  "Check that the voice settings haven't changed",
],
correct: 1,
explanation: "Always compare versions before promoting. Open the version diff and confirm every change is intentional – if anything looks unexpected, investigate before promoting.",
}

## What's next?

You have a solid foundation. Here's where you can go from here:

<CardGroup cols={2}>
  <Card title="Level 2: Advanced configuration" icon="graduation-cap" href="/learn/guides/advanced/add-complex-kb-topic">
    Add multi-turn topics, functions, response controls, audio tuning, and advanced diagnostics
  </Card>

  <Card title="Maintain your agent" icon="wrench" href="/learn/maintain/introduction">
    Best practices for keeping a live agent healthy and up to date
  </Card>
</CardGroup>

<Tip>
  **Level 2 picks up right where you left off.** You'll use the same agent you built here and start adding real capabilities – functions that talk to APIs, multi-turn conversations, and fine-tuned speech controls.
