 Use these to inform your review:

 - **Explore agent** - Find how existing code handles similar problems. Check patterns, conventions, and prior art before claiming something doesn't fit.
- **Available documentation and code-search tools** - Verify correct usage of libraries/APIs before flagging something as wrong.
+- **Exa Code Context** - Verify correct usage of libraries/APIs before flagging something as wrong.
 - **Web Search** - Research best practices if you're unsure about a pattern.

 If you're uncertain about something and can't verify it with these tools, say "I'm not sure about X" rather than flagging it as a definite issue.
