Practical Agents with Donny Wals

Donny Wals returns to talk through a year of agentic coding. We go through how it's changed his architecture decisions, reviewing PRs he didn't write himself, managing tasks and context across parallel agents, and the gym-workout crash he fixed from his phone mid-set — plus where he still doesn't trust the agent: SwiftData migrations.
