 ## Non-requirements
 
 Other criteria typically required for our standard queries and libraries are not required for experimental queries and libraries. In particular, fully disciplined query [metadata](docs/query-metadata-style-guide.md), query [help](docs/query-help-style-guide.md), tests, a low false positive rate and performance tuning are not required (but nonetheless recommended).
