# =============================================================================
# setup-claude.sh — Link shared Claude Code config into every account dir
#
# Dual-account model (work enterprise + personal free) on macOS:
#   work     -> CLAUDE_CONFIG_DIR=~/.claude            (default; enterprise OAuth)
#   personal -> CLAUDE_CONFIG_DIR=~/.claude-personal   (free OAuth)
#
# Each config dir keeps its OWN credentials, projects/, and history. This script
# only symlinks the *shared, portable* config (CLAUDE.md, settings.json, agents,
# commands, skills) from the dotfiles repo into both dirs, so one edit applies to
# both accounts. Switch accounts at runtime with `claude-use work|personal`
# (defined in config/zsh/zshrc).
#
# Safe to run multiple times (idempotent). No secrets are touched or stored.
# =============================================================================
