PEAKS No 49: Claude Fable 5 Lands, a New Defender Zero-Day Drops, and OpenCV Goes Native LLM
Hi there!
As agent usage increased in my daily workflow I’ve decided to deepen my knowledge in this subject. This decision is backed by three important factors: better understanding leads to better usage, new agents can be created based on my specific needs, being aware of agents’ internals means I can delegate more suited tasks for them while keeping the cognitively provoking ones for myself. I find the last one essential to keep my engineering skills in good shape. The goal is to develop the ability to identify routine jobs that consume time, but don’t enhance my craft, delegate them to agents and focus on the quests that stretch my art further. I believe that’s the key to productivity with agents.
So, after a bit of research, I enrolled in Hugging Face AI Agents Course.
