If this is a skill issue, feel free to let me know. In general Claude Code is decent for tooling. Onduty fullstack tooling features that used to sit ignored in the on-caller ticket queue for months can now be easily built in 20 minutes with unit tests and integration tests. The code quality isn't always the best (although what's good code for humans may not be good code for agents) but that's another specific and directed prompt away to refactor.

However, I can't seem to get Opus 4.6 to wire up proper infrastructure. This is especially so if OSS forks are used. It trips up on arguments from the fork source, invents args that don't exist in either, and has a habit of tearing down entire clusters just to fix a Helm chart for "testing purposes". I've tried modifying the CLAUDE.md and SPEC.md with specific instructions on how to do things but it just goes off on a tangent and starts to negotiate on the specs. "I know you asked for help with figuring out the CNI configurations across 2 clusters but it's too complex. Can we just do single cluster?" The entire repository gets littered with random MD files everywhere for directory specific memories, context, action plans, deprecated action plans, pre-compaction memories etc. I don't quite know which to prune either. It has taken most of the fun out of software engineering and I'm now just an Obsidian janitor for what I can best describe as a "clueless junior engineer that never learns". When the auto compaction kicks in it's like an episode of 50 first dates.

Right now this is where I assume is the limitation because the literature for real-world infrastructure requiring large contexts and integration is very limited. If anyone has any idea if Claude Opus is suitable for such tasks, do give some suggestions.
