Brackett opens a three-part agent benchmark

Brackett released the free, open-source Agent Effectiveness Index, scoring 3 agent systems—Brackett, OpenAI Codex and Anthropic Claude—across 3 dimensions: business understanding, operational execution and learning persistence, according to the benchmark’s launch announcement. Initial scores cover learning and comprehension; execution, transfer and retention scoring are still to come, so this is a measurement proposal rather than a verified leaderboard. Teams should record model version, tools, permissions and budget in every run, extending AISI’s evidence that agent evaluations need production-grade controls.
