In 3 years time this won't be how these tools work. So it feels like you're saying we should invest time in something that doesn't work and will be redundant in 6 months.
Worse, your example is one that AI agents are notoriously bad at. Give them an error like that and they're more liable to break the existing functionality to fix it, after littering the code with tons of log statements.
When most of the time the actual fix is a silly little mistake that takes one line to fix.
To get agentic coding working 9 months ago you were massaging context, 6 months ago you'd be hooking up MCP servers, 3 months ago you'd be writing a gazillion .claude files.
But all of that is utterly useless knowledge. That's not a transferrable skill.
Using AI is much more effective if you write the code yourself, using AI as a supercharged Stack Overflow.
A programmer + AI supercharged SO > A programmer + agentic coding
So stop wasting your time learning how to get agentic coding working today, especially as the method keeps changing. There's no point learning the voodoo and rain-dancing of this iteration of today's coding agents. Try them, and until they work, discard them.
