Reminder

Creates a one-shot cron job that delivers a reminder to Telegram at the specified time.

Workflow

1. Parse the user's message

Extract:

If when is ambiguous, ask for clarification before proceeding.

2. Compute the when value

Relative durations → pass directly as <n><unit>:

• "in 20 minutes" → 20m
• "in 2 hours" → 2h
• "in 1 day" → 1d

Absolute times → convert to ISO 8601 in Europe/Paris timezone:

TZ=Europe/Paris date -d "tomorrow 09:00" --iso-8601=seconds
# → 2026-03-03T09:00:00+01:00

3. Confirm with the user before scheduling

Show a summary and ask for confirmation:

Set this reminder?
- What: <text>
- When: <human-readable time>

Only proceed after the user confirms.

4. Run the reminder script

This is the only way to create a reminder. Do not use any other method.

{
  "tool": "exec",
  "command": "bash {baseDir}/scripts/remind.sh \"<when>\" \"<text>\""
}

The script handles everything: chat ID resolution, cron job creation, and verification.

5. Check the script output

The script prints the result. Look for:

• OK: reminder-xxx is scheduled → success
• ERROR: ... → report the exact error to the user

Do not confirm success unless the script output says "OK".

6. Confirm to the user

Only after seeing "OK" in the script output:

⏰ Reminder set!
📝 <text>
🕐 <human-readable time>

7. Error handling

• Never assume failure without running the script. Always execute it and report the actual output.
• Never invent a diagnosis. If something fails, show the raw error.
• Never use sessions_spawn, sleep, or any other method. Only use the script above.
• If the time is in the past → warn the user and ask for a new time
• If the reminder text is empty → ask what to remind them of
