What slop looks like in a codebase
Not obviously broken. That's the danger. Slop is subtle, systemic, and nearly invisible at PR review time.
- Follows patterns — but the wrong patterns for your domain boundaries.
- Introduces coupling because the model doesn't understand your architecture.
- Duplicates logic that exists three directories away — outside the agent's context window.
- Names things almost right but not quite. Close enough to merge, different enough to confuse the next engineer six months later.
What your metrics say vs. what's real
Your PR count is up 40%. Your defect rate is up too — you just haven't measured it yet. Or you have, and you're telling yourself it's a temporary adjustment period.
It's not. This is the new steady state unless you change something structural.
Six months in
Codebase 30% larger. 20% more coupled. Meaningfully harder to reason about than before you "adopted AI." That is a slop factory with enterprise pricing.
