ACE is a Python framework for Agentic Context Engineering that lets language models self-improve by treating contexts as evolving playbooks. It uses a Generator, Reflector, and Curator loop with incremental delta updates to accumulate and refine domain-specific strategies.

Use cases

• improve llm agent accuracy without fine-tuning
• evolve prompts automatically from execution feedback
• adapt a language model to a domain without labeled data
• reduce context collapse in long-running agents
• build self-improving agents that learn from experience

When to choose

• you want agents that accumulate and refine strategies over time
• you need adaptation without labeled supervision or gradient training
• you want lower latency and cost than fine-tuning or heavy rollout methods

When to avoid

• you need a simple one-shot prompt with no learning loop
• your task lacks any execution feedback signal for reflection
• you require guaranteed deterministic behavior from your agent
