Re-tuning my Claude Code setup for a new Opus model

TL;DR A new Opus model shipped, so I sat down to re-tune the agent harness I drive it with — the CLAUDE.md files, skills, hooks, and settings that shape every session. The surprising part: the most valuable changes weren’t trimming prompts for the smarter model. They were wiring the agent into infrastructure I already run — offloading bulk work to a local LLM (≈$0), a live homelab statusline, session tracing for an “action audit,” and a goal-drift monitor that uses the local model as judge.

The interview surfaces ~30% more actionable context than documentation alone. Full source code below. The Problem Nobody’s Talking About Nate B. Jones has a video that nails the core issue with AI agents: they fail because they lack tacit knowledge. Not the stuff in your docs — the stuff in your head. The 20-year veteran who just knows that the staging deploy takes longer on Thursdays because the batch job runs. The designer who can feel when a color palette is wrong without being able to articulate why. ...
