Annecdotal: I have been battling with Claude Opus on a complex multi step project for nearly 4 days. The initial research plan was sound. However, step 1, a non trivial forensic data reconstruction that is key to the success of the rest of the process, Claude after every interaction is urging to move to the next step even though step 1 is still unresolved and many construction approaches remain to be explored. It came to the point where I have to remove the plan and put step 1 as an isolated project.
