Score: 6.8/10 (Innovation: 8, Technical: 7, Documentation: 7, Utility: 5)

Proteus is a Python framework that lets any agent harness (prompts, memory, tools, skills, code) rewrite itself over context-fresh episodes, with harness-agnostic adapters and a measurement layer that quantifies structural and behavioral changes. Its differentiating idea is treating self-evolution as a measurable experiment—supporting goal, multi-goal, and no-goal regimes with hidden or visible evaluators—rather than just chasing benchmark scores.

Target audience: AI/ML researchers, agent framework developers, and engineers studying self-improving LLM systems
