+- Prepends mise's `command-wrappers/bin` so subscription account dispatch runs before inherited tool binaries, then appends `~/.local/share/mise/shims` and `~/.local/bin` so login shells and the uwsm session find mise-managed tools. The existing mise tool shims also dispatch these wrappers for SSH commands that run no shell setup; the PAM path needs no additional entry. `etc/mise/conf.d/omarchy-agent-accounts.toml` declares the Claude, Codex, and Grok wrappers; `mise reshim` builds them during user setup and migration. Each invocation resolves the selected account through `omarchy-agent-account-exec`, while an explicit provider home takes precedence. Credentials and running sessions remain in their original account homes.
