TwinMind Setup

Initialize a new TwinMind vault in the current working directory.

Pre-flight Checks

Before proceeding, check for existing installations:

1. TwinMind.md exists → Warn: "TwinMind.md already exists in this directory. Overwrite?" Ask user to confirm or abort.
2. Old-style .claude/skills/tm-* directories exist → Warn: "Detected old-style TwinMind installation (.claude/skills/tm-*). This plugin-based setup is separate. Consider removing old files to avoid confusion."
3. Vault directory already exists and contains files → Warn: "Directory <vault_dir>/ already exists with content. Setup will not overwrite existing vault data. Only missing structure files will be created."

If all checks pass or user confirms, proceed.

Interactive Configuration

Ask the user for customization (or accept defaults):

1. Vault directory name — default: vault
2. Locale — default: zh-TW
3. Domains — default: empty list (AI creates as needed)

Setup Steps

Resolve Plugin Root

Setup needs the plugin's absolute path to copy templates from. Read <cwd>/.claude/twinmind/config.json with the Read tool and use its pluginRoot field as <plugin-root> in the steps below.

Cold-start fallback: if <cwd>/.claude/twinmind/config.json does not exist, the SessionStart hook has not run for this vault yet (TwinMind.md is required to trigger it). In that case:

1. Use the Write tool to create <cwd>/TwinMind.md with minimal frontmatter (just vault_dir: vault\nvault_name: TwinMind\nlocale: zh-TW).
2. Tell the user: "請執行 exit 退出 Claude Code，然後 claude 重新啟動 session (讓 SessionStart hook 寫入 plugin 路徑)，再次執行 /setup 完成餘下步驟。"
3. Stop.

Copy and Customize

1. Copy <plugin-root>/templates/TwinMind.md to <cwd>/TwinMind.md.
2. Update frontmatter values based on user's choices (vault_dir, locale, domains).
3. Copy <plugin-root>/templates/vault/ directory structure to <cwd>/<vault_dir>/:
   • Create all subdirectories: System/, Cards/, Sources/, Atlas/, PARA/Inbox/, PARA/Actions/, PARA/Projects/, PARA/Archive/, PARA/Areas/, PARA/Tasks/.
   • Copy initial files: System/vault-index.json, Home.md, PARA/Dashboard.md.
   • Skip directories/files that already exist.
4. Create .gitignore in <cwd> if not exists, listing both .obsidian/ and .claude/twinmind/ (the latter holds plugin-generated shims that regenerate on every session start).

Completion

Report:

• Created TwinMind.md at project root
• Created vault structure at <vault_dir>/
• Next steps: "Open this directory in Obsidian to browse your vault. Start talking to Claude to capture knowledge!"
