Currently, the review tool uses a static list of comment examples:

	"comment" : "In the third code block, you are using `nsAutoStringN<256>` instead of `nsString`. This is a good change as `nsAutoStringN<256>` is more efficient for small strings. However, you should ensure that the size of `tempString` does not exceed 256 characters, as `nsAutoStringN<256>` has a fixed size."

Consider extracting `!Components.isSuccessCode(status) && blockList.includes(ChromeUtils.getXPCOMErrorName(status))` into a separate function with a descriptive name, such as `isBlockedError`."

We should use more relevant examples by searching comments on similar changes from the Vector DB.
