Frequently asked questions

What goes in a good prompt template?
A clear role or system instruction, well-named variable placeholders for the dynamic parts, explicit output format rules, and one or two few-shot examples when the task is ambiguous.
Should variables use double curly braces?
Double braces like {{name}} are the de facto convention because they rarely collide with code or natural prose. Single braces conflict with JSON and f-string syntax inside prompts.
How do I keep templates from breaking when inputs are long?
Put the volatile, long content (documents, transcripts) at the end of the prompt and keep instructions at the top. This survives context-window truncation and tends to improve instruction following.
