Agents shouldn’t make the same mistake every session.
Agentic Context Engine (ACE) is an open-source Python engine for adding a persistent learning loop to AI agents.
It helps agents reuse lessons from feedback and traces by maintaining a Skillbook: a collection of strategies that gets updated as tasks run, fail, and improve.
Key features:
• Persistent Skillbook – stores strategies that evolve across tasks instead of disappearing after one session
• Reflection loop – a Reflector analyzes execution traces while a SkillManager adds, refines, and removes strategies
• Simple quick start – install with uv, run ace setup, then use ACELiteLLM to ask, correct, and inspect learned strategies
• Trace-based learning – extract strategies from existing agent logs without re-running the original tasks
• Runner integrations – includes paths for LiteLLM, browser-use, LangChain, Claude Code, and MCP workflows
It’s open-source under the Apache License 2.0.

Anthropic just fumbled the ball big time.
Having the chance of capitalizing on the influx of new users post positive public perception on their stance towards defense > it disgusted all existing and new users instead by making their models rate limited and dumb.

Apple is banning vibecoding apps.
A new generation of personal software is emerging, and Apple is blocking it from reaching iPhone users.
Everyone can build apps now. Just not on iPhone.
@joni_vrbt I get shredded every time I make a post on reddit and paraphrase it with AI. The arguments in the comments bring nice traffic from people complaining about it though.
