What is the actual value of using agentic LLMs (rather than just LLM-powered autocomplete in your IDE) if it requires this much supervision and handholding? When is it actually faster / more effective?
Example: Say I discover a problem in the SPA design that can be fixed by tuning some CSS.
Without LLM: Dig around the code until I find the right spot. If it's been some months since I was there this can easily cost five minutes.
With LLM: Explain what is wrong. Perhaps description is vague ("cancel button is too invisible, I need another solution") or specific ("1px more margin here please"). The LLM makes a best effort fix within 30 secs. The diff points to just the right location so you can fine tune it.
