Score: 7.5/10 (Innovation: 8, Technical: 8, Documentation: 7, Utility: 7)

Life Forge is a behavioral regression testing framework for AI agents that builds a deterministic digital twin of an agent's tools, uses MAP-Elites quality-diversity search to find failure scenarios (e.g., unauthorized financial actions), and converts each finding into a replayable regression test for CI. It stands out for judging side effects rather than text outputs and for targeting real agent tool-use safety with a fuzzer-style corpus.

Target audience: AI/ML engineers and safety teams building tool-using LLM agents
