These guardrails are precisely what should be laid down in advance to enable workers to run safely with AI. Write all the rules in your AGENTS file, and point your AI reviewer at it. Encode whatever you can describe algorithmically in commit hooks. This will get you 90% of the way there, and peer review will take care of the rest.

I am hopeful that AI will empower smaller companies, where there is less deadweight, and consensus can be formed more quickly. Discussing what to build is not wasted time; it's one of the few things that favors humans.
