Something I want to stress today.

Claude Code changed everything. But not because of a model improvement.

MCP changed everything, but not because of a model improvement.

And today, skills change everything, but not because of a model improvement.

AI SYSTEMS are the thing to watch.

Not just the intelligence of the models.

People are useful in jobs because they connect dots and can do many different things.

That's what Anthropic has been doing here...building a unified system that connects dots.

🔍 OpenAI released Aardvark - an autonomous security agent powered by GPT-5 that hunts for vulnerabilities in code 🧵

Been waiting for them to release something like this...

The approach is pretty interesting - it analyzes entire repositories to build threat models before scanning each commit, then automatically reproduces exploits in a sandbox to confirm they're real.

📊 In benchmarks it identified 92% of known vulnerabilities, and already discovered 10 previously unknown CVEs in open-source projects during early testing.

✅ Available in private beta now, and they're offering pro bono scanning to select open-source repositories.

Uses reasoning and tool-use rather than traditional fuzzing.
