Re-enable p10k instant prompt (sudo-key ssh-add moved above it). Drop oh-my-zsh.sh (second compinit, update check); set up what OMZ plugins need ourselves. Cache java_home, go env, fzf --zsh output. Disable the kubecontext segment (ran kubectl per shell). Log starts over 1 s to ~/.cache/zsh/startup-slow.log to catch cold-start stalls. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
