ACE Framework

Agentic Context Engineering — a framework for self-improving language model agents.

ACE enables AI agents to learn from their own execution feedback through three collaborative roles: Agent, Reflector, and SkillManager.

How It Works

Sample → Agent → Environment → Reflector → SkillManager → Skillbook
                    (feedback)   (analyzes)   (updates)     (context)

The Skillbook accumulates strategies across runs, making every subsequent agent call smarter.
