Remind

Each reminder creates two files:

1. Script: scripts/reminders/remind-<id>.sh — sends the notification, then deletes itself and its plist
2. Plist: ~/Library/LaunchAgents/com.kithkit.reminder.<id>.plist — launchd job that fires at the scheduled time

The <id> is derived from the date/time: YYYYMMDD-HHMM (e.g., 20260131-1030).

Workflow

Setting a Reminder

1. Parse the request: Extract message, date, and time from arguments
2. Resolve relative dates: "tomorrow", "Friday", "tonight", etc. into absolute dates
3. Validate: Ensure the date/time is in the future
4. Create the script:

#!/bin/bash
# Reminder: <id> — <message summary>
# Fires: YYYY-MM-DD at HH:MM
# Self-cleaning: removes plist and script after running

export PATH="/opt/homebrew/bin:/usr/bin:/bin:$PATH"
BASE_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")/../.." && pwd)"

"$BASE_DIR/scripts/notify.sh" "REMINDER_MESSAGE"

# Clean up
launchctl bootout gui/$(id -u) ~/Library/LaunchAgents/com.kithkit.reminder.ID.plist 2>/dev/null
rm -f ~/Library/LaunchAgents/com.kithkit.reminder.ID.plist
rm -f "$0"

5. Make executable: chmod +x the script
6. Create the plist:

<?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.kithkit.reminder.ID</string>
    <key>ProgramArguments</key>
    <array>
        <string>/bin/bash</string>
        <string>PROJECT_DIR/scripts/reminders/remind-ID.sh</string>
    </array>
    <key>StartCalendarInterval</key>
    <dict>
        <key>Month</key>
        <integer>MONTH</integer>
        <key>Day</key>
        <integer>DAY</integer>
        <key>Hour</key>
        <integer>HOUR</integer>
        <key>Minute</key>
        <integer>MINUTE</integer>
    </dict>
    <key>StandardOutPath</key>
    <string>PROJECT_DIR/logs/reminder-ID.log</string>
    <key>StandardErrorPath</key>
    <string>PROJECT_DIR/logs/reminder-ID.log</string>
</dict>
</plist>

7. Load the plist: launchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/com.kithkit.reminder.ID.plist
8. Verify: launchctl list | grep reminder.ID
9. Confirm: Tell the user when the reminder will fire

Listing Reminders

1. Glob for ~/Library/LaunchAgents/com.kithkit.reminder.*.plist
2. For each, read the matching script in scripts/reminders/ to extract the message
3. Display: ID, scheduled time, message

Canceling a Reminder

1. Unload: launchctl bootout gui/$(id -u) ~/Library/LaunchAgents/com.kithkit.reminder.ID.plist
2. Delete plist: rm ~/Library/LaunchAgents/com.kithkit.reminder.ID.plist
3. Delete script: rm scripts/reminders/remind-ID.sh
4. Confirm cancellation

Date/Time Parsing

Resolve natural language to absolute dates:

If no time given and no natural-language time keyword (morning, tonight), default to 9:00 AM.

Notification Delivery

Reminders fire via scripts/notify.sh, which routes to the active notification channel (Telegram, desktop notification, etc.). Because reminders fire outside of active sessions — when the transcript stream is not running — notify.sh must deliver directly, not via the session transcript.

The notify.sh script should be implemented to match whichever channels are configured in kithkit.config.yaml. For a Telegram-enabled setup, this would call the Telegram send script directly. For other setups, it might use macOS notifications or another channel.

File Locations

Notes

• Reminders fire even when you're not in an active Claude Code session
• Each reminder is one-shot and self-cleaning (deletes its own script + plist after firing)
• If the Mac is asleep when a reminder is due, launchd fires it on next wake
• Always use scripts/notify.sh for reminders (not the transcript stream) since reminders fire outside sessions
• Ensure scripts/reminders/ directory exists before creating scripts
