One ~/.claude holds one setup: one set of settings and hooks, one memory, one login, one environment. cpb gives you as many Claude Codes as you need, each behind its own command, each isolated as far as you choose:

config home: its own CLAUDE.md, settings, hooks, memory, plugins and skills;
environment: its own variables, another model backend, another proxy;
login: its own Anthropic account;
process: a microVM that sees only the working directory.
