In February 2025, Spex66 enhanced the cognitedata/toolkit repository by developing a new hierarchy parameter for the cdf dump timeseries CLI command. This feature, implemented in Python, introduced a --hierarchy option that allows users to specify asset hierarchies directly from the command line, improving automation and enabling non-interactive workflows. By focusing on API integration and CLI development, Spex66 ensured that the new capability supports more granular data governance and reproducible outputs in downstream pipelines. The work included updating documentation and the changelog, reflecting a methodical approach to traceability and maintainability, though the scope was limited to a single targeted feature.
