Soft-launching an agent-first CLI Python module designed for efficient tool development for agents, not humans.

Step 1: Have Fable 5 create a series of skills and Claude.md files to have Opus 4.8 level up and bridge the gap.
Step 2: ??
Step 3: Profit

@BenjaminduPont Urging restraint will only embolden those that are lagging behind in the race. Regardless, this is a weird message during what should be a pre-IPO quiet period.

@JosephJacks_ @alexrives As a father of twins with mutated tubulin proteins, I +1 this suggestion.

@Its_Nova1012 The birthday “paradox”

[Brian Weisberg, CFA 🚀 AI & Data @weisberg]

@simpsoka It’s not useful when there are TONS of files and changes. Too cluttered and hard to navigate.

@BenjaminduPont Ironically, AI is just matrix math, so it’s the snake eating its tail.

AI companies are signing leases for millions of square feet in NYC. Importantly, they are leasing 60% more space than they need in anticipation of headcount growth.

This is the definitive “AI is creating jobs” metric that gives me hope.

@BrianDiSab Saving it for my commute. Will get back to you.

[Brian Weisberg, CFA 🚀 AI & Data @weisberg]

@BrianDiSab Most of the Fortune 500 pay a $250,000 large corporation filer fee annually. I’m certain they’d double that if we could make their lives—and legal fees—better as a partner.

@BrianDiSab Then the ones that need speed can foot the bill and those on a budget can have the same service as now.

[Brian Weisberg, CFA 🚀 AI & Data @weisberg]

@BrianDiSab If you increase fees, increase services: 24/7 filings, “instant” filings for a fee, etc. Treat the secretary’s office like a real business and it will grow revenue.

You will know that the AI labs believe in ASI when they disband their newly formed consulting (sorry “forward deployed engineering”) groups. As long as people are required to figure out how AI is useful & do organizational change & systems integration, jobs seem to be pretty safe

[Brian Weisberg, CFA 🚀 AI & Data @weisberg]

The analysis completely leaves out employment and other local-only cash outflows that benefit the local community. @BrianDiSab is there any research on jobs or other upside to data center projects?

[MTS @MTSlive]

Curious how $1 of AI capex flows through a datacenter project?

We break down the economics of datacenters at our latest drop.

I’ve been deep in this transformation for months. Models are now strong enough to find errors or speed bumps, and then fully document the solutions in our knowledge base. The agents can lead you an agent-friendly work OS.

@BrianDiSab For most of 2025, I was looking for work in Delaware and heard nothing back. It’s brutal out there. I had to get a job in PA an hour away.

There are far too many structural problems in DE for knowledge workers.

[Brian Weisberg, CFA 🚀 AI & Data @weisberg]

This should be a priority for Delaware. Any chance we can kickstart something @BrianDiSab or @BenjaminduPont ?

A Python module (and soon rust crate) for agent-native CLI tools.

[tooli CLI @tooli_cli]

Every AI agent framework has a tools chapter. None of them have a “what happens when the tool fails” chapter.

Agents parse stderr like humans read tea leaves. That’s the real bottleneck, not model intelligence.

Something needs to change.
