The core of the issue is that if I don't provide low-level specifications or explicitly map out how a new change interacts with the existing architecture, the entire process spirals. When I step back and let the agents make autonomous design decisions, they miss the subtle nuances that keep a system stable. The result isn't just a minor bug; it's a violation of our SLA or a structural mess that requires hours of refactoring.
I’ve reached a point where the "efficiency" of AI feels like a paradox. To get usable output, I have to:
-
Draft hyper-detailed technical specs that define every edge case.
-
Perform deep-dive code reviews on every single line the agent generates.
-
Manually trace dependencies to ensure the agent didn't break a legacy module.
When I tally up the time spent on prompt engineering, spec writing, and rigorous evaluation, it often exceeds the time it would take me to just write the implementation myself from scratch. It’s a massive cognitive tax. I'm not just coding anymore; I'm acting as a high-pressure supervisor for a very fast, very literal-minded junior engineer who lacks any sense of "big picture" context.
Is this just the current ceiling of prompt engineering, or am I missing a piece of the modern AI workflow? I’m curious if anyone else working on large-scale, legacy-heavy repositories is hitting this same wall. Are you finding ways to offload the "design decision" burden to the agent, or are you stuck in this cycle of being a glorified spec-writer?
I suspect the answer lies in how we bridge the gap between high-level intent and the actual codebase context, but right now, the overhead is making me wonder if I'm actually moving slower because of these tools.
