script to add today's date to your .cursor-updates file

update-cursor-date.sh

#!/bin/bash

# Path to the .cursor-updates file (update this with your own .cursor-updates file)
CURSOR_FILE="/full/path/to/your/.cursor-updates"

# Get today's date in YYYY-MM-DD format
TODAY=$(date +%Y-%m-%d)

# Create a temporary file
TMP_FILE=$(mktemp)

# Write the new date line
echo "## ${TODAY}" > "$TMP_FILE"

# Append the rest of the file starting from line 4 (skipping the header and old date)
tail -n +4 "$CURSOR_FILE" >> "$TMP_FILE"

# Add the header back with today's date
(
  echo "# Cursor Updates"
  echo ""
  echo "This file tracks significant changes made to the codebase through Cursor agent interactions. Today's date is: ${TODAY}"
  cat "$TMP_FILE"
) > "$CURSOR_FILE"

# Clean up
rm "$TMP_FILE" 

For macOS, to set this up to run every day at 1am (or when you next turn on your machine) you need a plist file. Ask o1 to create it or customize this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.psl.cursor-update</string>
    <key>ProgramArguments</key>
    <array>
        <string>/Users/kleneway/Projects/psl-platform/scripts/update-cursor-date.sh</string>
    </array>
    <key>StartCalendarInterval</key>
    <dict>
        <key>Hour</key>
        <integer>1</integer>
        <key>Minute</key>
        <integer>0</integer>
    </dict>
    <key>StandardErrorPath</key>
    <string>/Users/kleneway/Projects/psl-platform/scripts/cursor-update.err</string>
    <key>StandardOutPath</key>
    <string>/Users/kleneway/Projects/psl-platform/scripts/cursor-update.log</string>
</dict>
</plist> 

Then run a command that looks like this:

mkdir -p ~/Library/LaunchAgents && mv com.psl.cursor-update.plist ~/Library/LaunchAgents/ && launchctl load ~/Library/LaunchAgents/com.psl.cursor-update.plist

You might need to set the shell script as executable using chmod. For PC / Linux users, ask o1 to generate the step by step instructions
