- The query must have at least one true positive result on some revision of a real project.
Experimental queries and libraries may not be actively maintained as the [supported](docs/supported-queries.md) libraries evolve. They may also be changed in backwards-incompatible ways or may be removed entirely in the future without deprecation warnings.
6. **Query help files and unit tests**
- Query help (`.qhelp`) files and unit tests are optional (but strongly encouraged!) for queries in the `experimental` directories. For more information about contributing query help files and unit tests, see [Supported CodeQL queries and libraries](docs/supported-queries.md).
Experimental queries and libraries may not be actively maintained as the supported libraries evolve. They may also be changed in backwards-incompatible ways or may be removed entirely in the future without deprecation warnings.
After the experimental query is merged, we welcome pull requests to improve it. Before a query can be moved out of the `experimental` subdirectory, it must satisfy [the requirements for being a supported query](docs/supported-queries.md).
