Four years of ChatGPT history. Two years of Claude projects. Custom instructions, saved memories, accumulated context built up across thousands of conversations. And then a new harness ships — Cowork, Claude Code, Codex — and suddenly the question isn't which AI do I use. It's how do I move what I've built up, without starting over.

That's the problem this episode solves.

Chris Bradley walks through the discipline of building your Agentic DNA — the portable layer of identity, standards, and skills that travels with you across models and harnesses. The system has three phases: Extract what's already there, Consolidate it into a small set of files you own, Deploy those files into every environment where you work.

He's direct about what actually moves and what doesn't. Saved memories, in-app history, harness-specific automations — trapped. Files, skills, written context documents, structured prompts — free. The job is moving everything you can to the free side of that line, so the next time a new model or harness drops, you're productive in it within the hour.

The episode introduces the Portability Test — three questions for deciding what belongs in your DNA — and closes the Tools That Changed How I Work sub-series. Five episodes on tools. One episode on the layer that survives them.

Three things to try this week included.
