AI Tool
Cursor + Claude Sonnet combo
The Cursor + Claude Sonnet workflow is now fast enough that I'm writing production-ready Python in the time it used to take me to set up the environment. The tab completion understands intent, not just syntax.
Why it matters: Non-engineers can now build real tools. The bar for "technical PM" just shifted permanently.

Research
OpenAI's o3 on competitive coding benchmarks
The score on competitive programming benchmarks crossed a threshold where the gap between frontier AI and expert human performance is now measurable in months, not years. We're accelerating faster than most product strategies account for.
Why it matters: If you're not building AI-native, your roadmap has a 24-month expiration date.

Tool
Model Context Protocol (MCP) in production
Spent the week building MCP integrations for enterprise workflows. The composability is genuinely impressive — chaining tools, memory, and model calls with clean interfaces. This is what API-first actually looks like for AI agents.
Why it matters: MCP is becoming the plumbing of the agentic enterprise. Product teams should be mapping their tools to it now.
