The Claude agentic shift and what it changes for builders

I wrote up some thoughts on the Claude agentic revolution and honestly the biggest change I notice is the default: models now assume they'll use tools and take actions, not just answer.

That flips a lot of our assumptions about architecture. You stop designing for 'one clever response' and start designing boundaries — what the agent can touch, what it must confirm first.

If you've migrated an app to an agentic model lately, what surprised you?

I wrote this up in more detail in the full blog post — claude-agentic-revolution — with the deeper context, data, and code. Give it a read if you're curious.
