Is it just me or does Opus 4.8 jumps to conclusions way too fast instead of actually looking into stuff? I have an Obsidian vault that is separated into domains and it’s tailored to have a CLAUDE file at the root that tells it how to auto-discover domains and then inside each domain I have CONTEXT.md file that helps seed the context to that specific domain. So if I say “let’s work on our Home” (I’m using Home Assistant MCP and documenting stuff on Obsidian, I’ve been able to hero through my backlog like never before), it is supposed to read the CLAUDE, which points to the vault’s Index and then get the Home domain CONTEXT. The CLAUDE file also primes it with some general rules of how I want it to interact with me and some other useful authoring info related to the vault that it can then get on demand. all of this is very lean and intentional. Every time I run with Sonnet it goes through the paces perfectly as it’s supposed to. Opus just jumped the gun and started chatting with me without any context seeding, leading to unhelpful responses and me telling it to go fetch info before we continue. Just now it assumed I had made a decision from “”“memory”“” without actually diving into any of my docs. I have to constantly call it out and then it throws the “you’re right” schtick. “Fair — that’s a real possibility, and I shouldn’t have asserted” Sonnet on Medium/High seems to just be the right threshold. I tried Fable and oh boy it was awesome, it would gather all info very quick and steer things into a better direction than what I was initially going for. But yeah, Opus has not been it. submitted by /u/Final_Injury3744
