pub fn build_system(
schema_dump: &str,
cache_schema: Option<CacheControl>,
) -> Vec<SystemBlock>Expand description
Build the system array for an Anthropic request.
cache_schema controls whether the schema block carries a
cache_control breakpoint. Pass None to skip caching (e.g.,
schemas under the model’s ~2K-token minimum cacheable prefix —
they silently won’t cache anyway, so the cache_control marker is
noise without it).
