HOW TO WORK AND COMPOUND WITH AI

Provide good context, encode your taste as config, make verification easy, delegate bigger tasks, and close the loop. Every finished artifact becomes context for the next session, and each correction updates a config that reduces future errors. These practices aren't specific to AI - it's how you onboard and work with any new collaborator.

The downsizing will allow Coinbase to emerge from this period leaner, faster, and more efficient for its next phase of growth.
