During November 2025, Dorien Koelemeijer enhanced the reliability of prompt injection detection metrics in the block/goose repository. By switching metric logging from gauges to counters and sanitizing metric explanations, Dorien addressed Datadog export errors that previously disrupted monitoring pipelines. This technical approach improved the stability of metric exports, reduced false positives, and enabled more dependable incident detection for security monitoring. The work involved targeted changes to metrics instrumentation and log handling, leveraging Rust and Go alongside Datadog integration and observability best practices. Dorien’s focused engineering delivered a deeper, more robust foundation for security alerting and data quality in production environments.
