DIG.BENCH

dig.bench is a benchmark that measures whether an agent can experiment to discover a game's unknown rules. It contains 70 text-based games, 21 that have been publicly released. Progress is scored by whether the game can be beaten within a limited number of steps. Humans can make the discoveries necessary to solve even the hardest games, while the best models struggle to beat games in the top tier.

DEADAIR

deadair is an open-source tool that audits live SIEM rule inventories to identify active detections that are failing silently due to missing, stale, or schema-incompatible telemetry. By utilizing read-only metadata credentials, the tool resolves rule inputs against backend semantics to verify index resolution, document freshness, and ingest lag across Elastic Security and OpenSearch Security Analytics environments. Security engineering teams can deploy deadair to generate fleet-wide coverage reports or to automatically gate candidate detection rules within their CI pipelines.
