Multiple Profiles for Claude Code

Claude Code reads all configuration from a single directory (~/.claude by default). The CLAUDE_CONFIG_DIR environment variable overrides this, redirecting everything -- settings, credentials, CLAUDE.md, project configs, and .credentials.json -- to a different directory.

This gives you completely isolated profiles with separate subscriptions, plugins, hooks, and instructions.

Setup

1. Create profile directories

	#!/usr/bin/env zsh
	# claude-borrow-session -- surface a Claude Code session JSONL from one
	# CLAUDE_CONFIG_DIR ("FROM") inside another ("TO") so the TO account's
	# `--resume` picker can pick it up.
	#
	# Background: Claude Code's CLAUDE_CONFIG_DIR env var lets you run multiple
	# accounts side by side, each with its own config dir. Sessions live at
	# $CLAUDE_CONFIG_DIR/projects/<encoded-cwd>/<session-id>.jsonl, and `--resume`
	# only sees sessions inside the running process's config dir. This helper
	# symlinks a single session JSONL from FROM into the parallel path under TO.

	#!/usr/bin/env bash
	# ~/.claude/hooks/cli-preferences.sh
	# Single source of truth for preferred-CLI enforcement.

	# Four behaviors, one file:
	# inject → emit a context block (SessionStart hook)
	# enforce → PreToolUse(Bash) gate: blocks banned cmds, fails open if alt missing
	# bootstrap → brew-installs any missing alternatives
	# list → human-readable table for terminal use
