“I think I first saw it being used in CrewAI [0] almost 2 years ago, now.”
“For decomposable tasks specifically, this causes two problems”
“port the agent logic into a framework like LangGraph or CrewAI”
“the commit message does not say anything about a potential compromise”
“they typically don't provide durable execution—if the process crashes, the agent will restart from scratch”
“The best example of this is probably CrewAI and Alibaba CoPaw.”
“No framework we could find — AutoGen, CrewAI, LangGraph, OpenAI Agents SDK, Google A2A — answers a basic question”
“We stopped using both about 6 months ago”
“LangGraph, CrewAI, AutoGen -- all of them assume the work has a shape before it starts.”
“Every framework I've audited makes the same assumption: the agent is trusted.”
“popular frameworks tend to be on the heavy side”
“Python solutions often felt sluggish, especially during tool execution and agent coordination”
“Out of all the others Crew AI was my second choice.”
