It seems likely that you are trying to include code snippets within a prompt using Mustache formatting, which uses `{{` and `}}` for placeholders. To escape these characters, you can use triple braces `{{{` and `}}}` or escape them with a backslash. However, the specific method for escaping may depend on the context in which you are using the prompt.
If you are using Phoenix, you can format your prompt using Mustache or F-string formats. For Mustache, you can escape variables by using triple braces or by adding a backslash before the braces. For example, to include a code snippet, you might use:
```
{{{code_snippet}}}
```
Would you like more details on how to implement this in your specific use case?
