+## Implementation Steps for Browser Automation
+
+### Using Claude in Chrome Extension
+
+1. **Open New Tab**
+   - Execute: Click "+" button to open new tab
+   - Verify: New blank tab appears
+
+2. **Navigate to Sheet**
+   - Execute: Paste URL into address bar
+   - Verify: Google Sheets loads with the target spreadsheet
+   - Wait: Sheet data fully loads (may take 2-3 seconds)
+
+3. **Ask User for Block Size**
+   - Execute: Display prompt "How many rows should I copy? (e.g., 17, 20, 25)"
+   - Wait: User provides row count
+   - Validate: Ensure input is a positive integer
+   - Record: User-specified row count (e.g., 17)
+
+4. **Select Entire Rows (Not Just Cells)**
+   - Execute: Click on row number 1 (left side gray area with row numbers)
+   - Hold Shift and click on end row number (e.g., row 17)
+   - Alternative: Click row 1, then Shift+Click row 17
+   - Verify: Entire rows 1-17 are highlighted (blue/gray background)
+   - **Critical**: Select ROWS not cells - this preserves all formatting
+
+5. **Copy Selected Rows**
+   - Execute: Ctrl+C (Windows/Linux) or Cmd+C (Mac)
+   - Alternative: Right-click on selected rows → "Copy"
+   - Verify: Moving dotted border appears around selected rows (marching ants animation)
+
+6. **Insert Copied Rows at Top (CRITICAL OPERATION)**
+   - **Method 1 (Recommended - One-Step Operation):**
+     - Right-click on row number 1
+     - Select: "Insert X copied rows above" where X = number of copied rows
+     - This inserts AND pastes in one operation
+     - Verify: New rows appear at top with copied data
+
+   - **Method 2 (Two-Step Alternative):**
+     - Right-click on row number 1
+     - Select: "Insert X rows above" to create empty rows
+     - Click cell A1
+     - Press Ctrl+V (or Cmd+V) to paste
+     - Verify: Data appears in new rows
+
+7. **Verify Insertion Success**
+   - Check: New block appears at rows 1-17 (or user-specified row count)
+   - Check: Original first block now starts at row 18 (= blockHeight + 1)
+   - Check: All data intact, no overwrites
+   - Check: Formatting preserved (colors, borders, fonts)
+
+8. **Update Date Range in A1**
+   - Execute: Click on cell A1 to select it
+   - Execute: Press Delete or Backspace to clear existing data
+   - Calculate the new date range:
+     - Yesterday: If today is 1/8/2026, yesterday is 1/7/2026
+     - Start date: 1st of yesterday's month = 1/01
+     - End date: Yesterday's date = 1/07
+     - Format: M/DD-M/DD/YYYY (no spaces)
+   - Execute: Type the new date range: "1/01-1/07/2026"
+   - Execute: Press Enter to save
+   - Verify: A1 shows the new date range in correct format
+
+9. **Save and Verify Complete Operation**
+    - Execute: Google Sheets auto-saves (wait for "Saved to Drive" message)
+    - OR press Ctrl+S / Cmd+S if needed
+    - Final verification checklist:
+      - [ ] New block at rows 1-17 with updated date in A1
+      - [ ] Original block now at rows 18-34
+      - [ ] Second original block at rows 35+
+      - [ ] All data present, no loss
+      - [ ] Formatting preserved
+      - [ ] Sheet saved successfully
+
+## Key Data Points to Track
+
+When implementing, track these variables:
+
+```
+blockStartRow = ALWAYS 1 (most recent block starts at row 1)
+blockEndRow = user-provided row count (e.g., 17)
+blockHeight = blockEndRow (same as user input)
+headerText = the full text in cell A1 before update
+yesterday = today's date - 1 day
+newEndDate = formatted yesterday's date (M/D format)
+```
+
+## Error Handling
+
+Handle these scenarios:
+
+1. **Invalid User Input for Row Count**
+   - Action: Re-prompt with clear instructions
+   - Message: "Please provide a valid positive number (e.g., 17, 20, 25)"
+   - Note: Ensure input is an integer greater than 0
+
+2. **User Unsure of Row Count**
+   - Action: Provide guidance on how to find the row count
+   - Message: "Look at column A and find where the next date range pattern appears. Count rows from 1 to that row minus 1."
+   - Note: Typical sizes are 15-25 rows
+
+3. **Date Format Mismatch**
+   - Action: Analyze existing date format and match it
+   - Message: "Adapting date format to match existing data"
+
+4. **Sheet Not Accessible**
+   - Action: Verify permissions and retry
+   - Message: "Unable to access sheet, check permissions"
+
+5. **Copy/Paste Failure**
+   - Action: Retry operation
+   - Message: "Operation failed, retrying..."
+
