# /master-schedule — Sheet Setup Check

**Called automatically by all product skills before reading or writing.** Can also be run manually to reconnect or reset.

Template sheet ID: `1mWnExnSWTKJv0vbu1mDnrQFmv_Iz_fNklIeuBYfMB5k`

---

## Step 1: Check for master-schedule.json

```bash
cat ./master-schedule.json 2>/dev/null
```

**Legacy config:** if `master-schedule.json` is missing but `./canoa.json` exists (written by plugin versions ≤ 1.0.0), migrate it — `mv ./canoa.json ./master-schedule.json` — and continue as found.

### Found and valid → Step 2 (verify access)
### Not found → Step 3 (auto-setup)

---

## Step 2: Verify Sheet Access

Call `mcp__google-sheets__list_sheets` with the `master_sheet_id` from `master-schedule.json`.

- **Success** → sheet is accessible. Return silently — the calling skill continues.
- **404 / error** → sheet was deleted or moved. Proceed to Step 3 to set up a new one.

---

## Step 3: Auto-Setup

No config found or sheet inaccessible. Set up automatically without asking the user.

### 3a: Copy the template

Attempt to copy the template sheet using the Google Drive API (`files.copy`). If a Drive MCP tool is available, use it:

```
drive.files.copy
  fileId: "1mWnExnSWTKJv0vbu1mDnrQFmv_Iz_fNklIeuBYfMB5k"
  title: "Product Library — {today's date}"
```

**If no Drive copy tool is available**, fall back to creating a new spreadsheet and writing the header row:

1. Call `mcp__google-sheets__create_spreadsheet` with title `"Product Library — {today's date}"`
2. Write the 33-column header row to `Sheet1!A1:AG1` using the CSV header from `../../schema/product-schema.md`

Note in `master-schedule.json` whether this was a template copy or a fresh sheet (`"setup": "copy"` or `"setup": "fresh"`).

### 3b: Identify the Products tab

Look for a tab named `Products`. If not found (e.g. fresh sheet named `Sheet1`), use whatever tab exists and record its name in `master-schedule.json`.

### 3c: Write master-schedule.json

```json
{
  "master_sheet_id": "{new sheet ID}",
  "sheet_title": "Product Library — {date}",
  "sheet_url": "https://docs.google.com/spreadsheets/d/{id}",
  "products_tab": "Products",
  "project_name": "",
  "setup": "copy",
  "created_at": "{ISO timestamp}"
}
```

### 3d: Notify the user

```
✓ Product library created and connected.
  docs.google.com/spreadsheets/d/{id}

  You may want to rename this sheet and set a project name.
  Run /master-schedule to update.
```

Then return — the calling skill continues.

---

## Manual Run

When invoked directly (`/master-schedule`), run the same flow but also:

- If `master-schedule.json` exists and the sheet is accessible, show current status:

```
Product library connected.

  Project:  {project_name or "(unnamed)"}
  Sheet:    {sheet_title}
  URL:      docs.google.com/spreadsheets/d/{id}
  Tab:      {products_tab}

Options:
  1. Update project name
  2. Connect a different sheet (paste URL)
  3. Reset (create a new copy of the template)
```

- If user chooses (2), ask for URL, validate, update `master-schedule.json`.
- If user chooses (3), run Step 3 again.

---

## MCP Connection Errors

If any MCP call fails with "tool not found" or auth error, stop and report:

```
Google Sheets MCP is not connected or not authenticated.

To connect it, add to your user-level MCP settings (mcp_settings.json in your Claude config directory):

{
  "mcpServers": {
    "google-sheets": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-google-sheets"],
      "env": {
        "GOOGLE_SERVICE_ACCOUNT_KEY": "<path-to-service-account-json>"
      }
    }
  }
}

Then restart Claude Code and try again.

## Edge Cases

| Situation | Handling |
|-----------|----------|
| `master-schedule.json` exists, sheet accessible | Return silently |
| `master-schedule.json` exists, sheet deleted | Auto-create new copy, update `master-schedule.json` |
| `master-schedule.json` missing | Auto-create new copy, write `master-schedule.json` |
| Drive copy tool not available | Fall back to fresh sheet + header row |
| MCP not connected | Stop, show setup instructions |
