Agentic Context Engine (ACE)

Skill by ara.so — AI Agent Skills collection.

ACE is a framework that adds persistent learning capabilities to AI agents. Unlike traditional agents that forget everything between sessions, ACE maintains a Skillbook — a living collection of strategies extracted from execution traces. The framework uses a Recursive Reflector that writes and executes Python code to analyze traces and extract actionable patterns.
