> The planning phase will produce plans that claude can iterate on for 3+ hours in some cases, if you tell it to complete the entire task in one shot, and the robust test validation / change set analysis will catch agents solving an easier problem because they got frustrated or not following directions. Don't you run into context nightmares though? I was coming up with very detailed plans (using zen to vet with other models), but I found claude just doing the wrong thing a lot of the time, ignoring and / or forgetting very specific instructions and rules, especially across context compactions. There's this one time that really sticks out in my mind because I had to constantly correct it; when to use ->> versus -> and handle null / type checks with PostgreSQL JSONB. Vibe coders would miss this sort of thing with testing unless they knew that JSONB null is not the same as SQL NULL (and other types too). When working with nested data, you probably won't have test coverage for it. This is just one of many examples too.

Agreed 100%. For those of us who have already spent ungodly hours creating hyper-detailed specifications for AI, the take that this is the solution to working with AI coding agents seems ridiculously naive. For context, I've also seen this behavior in Claude Code, and despite initially being extremely bullish on the technology, it's almost convinced me that it just isn't ready for prime time no matter what the hucksters might tell you. When you start seeing this you quickly realize that it doesn't really matter how many guardrails you put in place, or how detailed your specification is, if your coding agent randomly decides to ignore your rules or specifications(even in 'brand new context' scenarios). I've lost track of how many times I've asked Claude why did you do this, when it expressly says to do the opposite in the Claude.md file(including words like 'important' or 'critical'), or a specification document that you read right before implementing with a brand new context. Naturally, Claude's reply will be some variation of 'You're absolutely right to call me out on this. I should have done it the way it was spelled out in the specification.'

  I have tripwires in my codebase for when Claude tries to run benchmarks with mock/synthetic data because it had a hard time getting the benchmark to run and decided to yeet it, to avoid potential scientific credibility issues, LOL. You can put the system on rails, but it's an engineering problem, these things are noisy program emitters with some P(correct|context), you can model them as noisy channels and use the same error correcting codes to create channels with arbitrarily low noise.

The key is to have each step have very detailed instructions, and tell claude to dispatch the appropriate domain expert subagent for each step with the specific instructions for that step. That keeps root context hot, and each subagent only gets the instructions it needs and has a fresh context.
