I find great joy in adding heavy test coverage to the apps that I build, and then adding them to Github Actions to run automatically on deploy. Coding agents will write tests for you until the cows come home, so you can add them all.
Especially for people who rely on the agents to write their code, this adds a solid baseline of protection against the dumbest decisions, especially when combined with things like the [AI-powered PII protection[vibe-coding-to-agentic]] .
