The cost of generating code has collapsed. The cost of owning it has not. That asymmetry is quietly breaking how engineering teams decide what to build. A 40-minute Slack thread debating whether to surface a last_active_at timestamp now costs more than the four-line diff an agent produces in the same window. The old instinct, protect the team from small asks that aren't actually small, was built on a premise that no longer holds universally.
The generated patch is not the deliverable. It is a price check. A clean diff touching two files with a passing test means the debate was the expensive part. The same request coming back tangled in auth middleware means the request was never small, and you learned that in 30 minutes instead of two days. The useful questions become concrete: does it sprawl across five packages, does it resist being tested, does it quietly require a new product decision, would you own this behavior in six months. Those are better than arguing from vibes about scope creep.
The dividing line is not whether an agent can write it. It is whether a human can validate and own the result. A 1,000-line diff that passes CI but nobody wants to review is a deferred cost, not a cheap change. Authorization logic, data-retention semantics, billing, compliance, anything that moves the product contract: hard no regardless of how clean the diff looks. The article's full framework for constrained attempts, smallest possible patch, behind an existing feature flag, no public contract changes, full file list with risks called out, is worth reading in detail. It is a practical method for replacing 'is this in scope' with 'here is what it costs, do we want to pay it.'
