Complete reference for the tools Claude Code can use, including permission requirements and per-tool behavior.

Claude Code also keeps a fifth file, ~/.claude.json, that it writes for itself; you don’t need to edit it. It holds your sign-in session, MCP server configurations, per-project state such as trust decisions, and the global config keys that /config writes for you.

Claude Code stores its configuration and auth credentials in ~/.claude by default. The CLAUDE_CONFIG_DIR environment variable overrides this location. By creating a separate config directory per account - each with its own OAuth credentials - and symlinking shared resources back to a canonical source, you get:

• Separate billing/authentication per account
• Shared sessions - resume any session from either account
• Shared settings, plugins, commands, plans, and skills - configure once, use everywhere

​ One-Time Setup This setup is done once on your machine, outside of Maestro. ​

1. Authenticate Each Account Start Claude Code normally and complete OAuth for your first account:

claude

Complete OAuth for account A (e.g., personal)

Copy the authenticated config to a named directory:

cp -a ~/.claude ~/.claude-personal

Then authenticate your second account:

mv ~/.claude/.claude.json ~/.claude/.claude.json.bak claude

Complete OAuth for account B (e.g., work)

cp -a ~/.claude ~/.claude-work rm ~/.claude/.claude.json.bak

The main ~/.claude/ directory doesn’t need its own .claude.json. It serves as the canonical source for shared resources.

​ 2. Symlink Shared Resources For each account directory, replace local copies with symlinks back to ~/.claude so settings, plugins, and sessions stay in sync:

Repeat for each account directory (e.g., ~/.claude-personal, ~/.claude-work)

CONFIG_DIR=~/.claude-personal

Back up directories that will be symlinked

mv $CONFIG_DIR/projects $CONFIG_DIR/projects-pre mv $CONFIG_DIR/todos $CONFIG_DIR/todos-pre mv $CONFIG_DIR/session-env $CONFIG_DIR/session-env-pre

Remove files/dirs that will become symlinks

rm -rf $CONFIG_DIR/commands $CONFIG_DIR/ide $CONFIG_DIR/plans $CONFIG_DIR/plugins $CONFIG_DIR/skills rm -f $CONFIG_DIR/settings.json $CONFIG_DIR/CLAUDE.md

Create symlinks

ln -s ~/.claude/commands $CONFIG_DIR/commands ln -s ~/.claude/ide $CONFIG_DIR/ide ln -s ~/.claude/plans $CONFIG_DIR/plans ln -s ~/.claude/plugins $CONFIG_DIR/plugins ln -s ~/.claude/skills $CONFIG_DIR/skills ln -s ~/.claude/settings.json $CONFIG_DIR/settings.json ln -s ~/.claude/CLAUDE.md $CONFIG_DIR/CLAUDE.md ln -s ~/.claude/todos $CONFIG_DIR/todos ln -s ~/.claude/session-env $CONFIG_DIR/session-env ln -s ../.claude/projects $CONFIG_DIR/projects

Set CLAUDE_CONFIG_DIR to your account’s config path (e.g., /Users/you/.claude-personal)

Fascinating prompt engineering and injection (harmless).
