A BUNCH of work on github.com/kevmoo/cogn... there is now a separate `data_flow` tool to help humans (and agents) understand how to slice and dice huge functions. We now aggressively push for functional, private, top-level functions. Bug fixes, too!
Let me know if you try it!

On CNN, El-Sayed is asked about this Trump post.
He says it represents "two different visions of America:"
"Two people who don't like each other but are joined in the interest of making billions of dollars off of you. Or, two people who genuinely love each other, enjoying some panacakes together."

Here's a fun discovery: I'm coding up some secretary work (see previous post) to go through my agent/session history for the week so I can see where I'm spending time.
TWICE the agent got "hypnotized" going through old work and started DOING THE OLD WORK! 🤷🤭🤦

My ~six month agent progress.
- I have a little code helper.
- I have an intern
- I have a team of interns
- I have a development team
- I have a development team and a work secretary and a personal secretary
(The personal secretary is lagging the work one, but give him time.)

Pondering updating my `AGENTS.md` file.
If I start a prompt with "dude!", I'm likely really mad at something you did.
(It is so weird/fascinating to reflect on my agent interaction patterns as a mirror to my own communication style.)

Talking to agents most of my day, I'm noticing my conversational quirks that cause problems with LLMs. My default is to make even my instructions questions. "Could we try...?" "What if we...?"
Then I'm annoyed when I'm REALLY asking a hypothetical and the agent starts coding!
