Things Setup

Things 3 Setup

Connect Things 3 to Dex for bi-directional task sync. No account needed. Everything stays on your Mac. Works offline.

What This Enables

Once connected, Dex can:

• Task Sync: Create tasks in Things 3 when you add them in Dex, and vice versa
• Daily Plan: Pull in tasks you created in Things and merge them into your plan
• Completion Sync: Complete a task in either place — it syncs to the other
• Priority Mapping: P0/P1 tasks go to your Today list, P2/P3 to Anytime
• Pillar Mapping: Dex pillars map to Things Areas for organized task views

Privacy

• Everything is local. Things 3 uses AppleScript — no cloud API, no tokens, no accounts
• Tasks sync between two apps on YOUR Mac. Nothing leaves your machine
• No credentials to store. No tokens to expire. No OAuth flows
• Works completely offline

When to Run

• User types /things-setup
• User asks about connecting Things 3
• User wants task sync with a Mac-native app
• During /integrate-mcp if Things is mentioned
• During onboarding if user mentions Things 3

Setup Flow

Step 1: Platform Check

Things 3 is macOS only. Verify:

1. Check if running on macOS (process.platform === 'darwin' or uname check)
2. If not macOS:

   Things 3 is a macOS-only app. It won't work on this platform.
   
   For cross-platform task sync, consider:
   - /todoist-setup (works everywhere)
   - /trello-setup (web-based)
   

   Stop here.

Step 2: Check if Already Connected

1. Read System/integrations/config.yaml
2. If things.enabled: true, skip to Step 7 (Reconfigure)
3. If not configured, continue

Step 3: Check if Things 3 is Installed

Run a quick AppleScript test:

osascript -e 'tell application "System Events" to (name of processes) contains "Things3"'

Or check if the app exists:

ls /Applications/Things3.app 2>/dev/null || ls "$HOME/Applications/Things3.app" 2>/dev/null

If Things 3 is not found:

I can't find Things 3 on your Mac.

Things 3 is available from the Mac App Store:
https://apps.apple.com/app/things-3/id904280696

Once installed, run /things-setup again.

Stop here.

If found:

Things 3 detected. This is the simplest integration to set up — no accounts or API keys needed.

Everything stays on your Mac and works offline. Ready?

Wait for confirmation.

Step 4: Add the things3-mcp Server

Check the user's MCP configuration. If things3-mcp is not listed:

1. Explain:

I need to add the Things 3 connector to your Dex configuration.

This uses a lightweight AppleScript bridge — no accounts, no API keys.
It talks directly to Things 3 on your Mac.

2. Add to the user's .mcp.json:

{
  "things3-mcp": {
    "command": "npx",
    "args": ["-y", "things3-mcp"],
    "env": {}
  }
}

3. Tell the user the MCP server needs to restart for changes to take effect.

Step 5: Test the Connection

Run a quick test to verify AppleScript access:

1. List Things Areas:

   osascript -e 'tell application "Things3" to get name of areas'
   

2. List Things Projects:

   osascript -e 'tell application "Things3" to get name of projects'
   

If macOS prompts for AppleScript permission:

macOS is asking for permission to control Things 3. Click "OK" to allow.

This is a one-time prompt. Things 3 uses AppleScript for local communication —
no network access is involved.

Show results:

Connection test passed.

Your Things 3 setup:
- Areas: [list of areas]
- Projects: [list of projects]

If the test fails, jump to Troubleshooting.

Step 6: Configure Mapping

Map Dex pillars to Things Areas:

Now let's map your Dex pillars to Things Areas.

Your Dex pillars:
1. Deal Support
2. Thought Leadership
3. Product Feedback

Your Things Areas:
[list from Step 5]

I'll suggest a mapping — adjust if needed:

| Dex Pillar | Things Area |
|------------|-------------|
| Deal Support | [best match or "Deal Support"] |
| Thought Leadership | [best match or "Thought Leadership"] |
| Product Feedback | [best match or "Product Feedback"] |

Does this mapping look right? I can create any missing Areas in Things.

If areas don't exist, offer to create them:

osascript -e 'tell application "Things3" to make new area with properties {name:"Deal Support"}'

Then ask about sync behavior:

One more question: How should task sync work?

1. **Auto-sync** — Tasks sync automatically between Dex and Things
2. **Ask each time** — I'll confirm before syncing each task

Most people prefer auto-sync. Which do you want?

Step 7: Save Configuration

Write to System/integrations/config.yaml — update the things section:

things:
  enabled: true
  configured_at: YYYY-MM-DD
  mcp_server: things3-mcp
  auth_type: none
  task_sync: true
  sync_mode: auto
  area_mapping:
    deal_support: Deal Support
    thought_leadership: Thought Leadership
    product_feedback: Product Feedback
  features:
    task_sync: true
    external_task_merge: true

If the file already exists, only update the things: section. Preserve other integration configs.

Step 8: Capability Cascade

Now that Things is connected, highlight what changes:

Things 3 is connected.

Here's what changes now:

- **/daily-plan** syncs tasks from Things into your morning plan
- **Task creation** in Dex mirrors to Things (P0/P1 → Today, P2/P3 → Anytime)
- **Task completion** syncs both ways — finish in either app
- **Pillars → Areas** keep your Things organized by Dex structure

No accounts. No tokens. No expiration. Works offline.

Tip: Tasks you create directly in Things will appear in your next /daily-plan.

Troubleshooting

Things 3 Not Installed

Things 3 must be installed from the Mac App Store. It's a paid app (~$49.99). Once installed, run /things-setup again.

AppleScript Permission Denied

macOS may block AppleScript access. To fix:

1. Open System Settings > Privacy & Security > Automation
2. Find your terminal app (Terminal, iTerm2, etc.)
3. Enable the toggle for Things3
4. Retry the setup

"Things3 got an error" Messages

Things 3 must be running for AppleScript to work. Open Things 3, then retry.

Areas Not Showing

If no Areas appear during setup:

1. Open Things 3
2. Go to Settings > General
3. Make sure Areas are enabled
4. Create at least one Area, then retry

Sync Conflicts

If a task is edited in both Dex and Things between syncs:

• Dex is the source of truth for task status
• Things is the source of truth for task title edits
• Notes merge (Dex context is appended, not overwritten)

Reconfiguration

If the user runs /things-setup when already configured:

1. Show current config from System/integrations/config.yaml
2. Offer options:
   • Update pillar-to-area mapping
   • Change sync mode (auto vs. ask)
   • Re-test the connection
   • Disconnect Things

Disconnect Flow

If user wants to disconnect:

1. Update System/integrations/config.yaml:

   things:
     enabled: false
   

2. Confirm: "Things 3 is disconnected. Tasks will no longer sync. Run /things-setup anytime to reconnect."
