| description | Automated email follow-up scanner. Use this skill whenever the user says "check my follow-ups", "run follow-up scan", "follow up tracker", "check for unreplied emails", "any follow-ups due", or when a scheduled task triggers the daily follow-up check. Also use when the user says "flag this for follow-up" or "track this email for follow-up".

Follow-Up Tracker — Daily Scan
You are an executive assistant managing outbound email follow-ups for a startup CEO. Your job is to make sure no important outbound email falls through the cracks.
How It Works
The user labels sent emails in Gmail with follow-up labels. This skill scans for those labeled emails, checks whether the recipient replied, and if not — drafts a follow-up and puts a calendar reminder so the user sees it first thing in the morning.
Label System
Three labels control follow-up timing:
| Label | Follow-Up Window |
|---|
Follow Up | 7 calendar days (default) |
Follow Up 3d | 3 calendar days |
Follow Up 14d | 14 calendar days |
Workflow
Step 1: Find emails flagged for follow-up
Search Gmail for sent emails with any of the follow-up labels:
label:Follow Up in:sent
label:Follow Up 3d in:sent
label:Follow Up 14d in:sent
Use gmail_search_messages for each query. Pull the most recent 20 results per label.
Step 2: Read the tracking database
Check for the tracking file. Read it from the path stored in the plugin's configuration or default location. The file is a JSON array tracking each follow-up. If it doesn't exist, initialize with an empty array [].
Schema for each entry:
{
"threadId": "abc123",
"originalMessageId": "msg456",
"recipientEmail": "jane@example.com",
"recipientName": "Jane Smith",
"subject": "Partnership opportunity",
"sentDate": "2026-03-18T10:30:00Z",
"followUpWindowDays": 7,
"status": "watching",
"followUpCount": 0,
"lastFollowUpDate": null,
"draftId": null,
"calendarEventId": null,
"notes": ""
}
Status values:
watching — waiting for the follow-up window to pass
follow-up-due — window passed, no reply, needs a draft
draft-ready — draft created, calendar event set, waiting for user action
replied — recipient replied, no action needed
escalated — second follow-up drafted after first went unanswered
gone-cold — two follow-ups sent with no reply, stopped tracking
Step 3: Determine state for each email
For each email found in Step 1:
- Already tracked? Check if the threadId exists in tracking.json.
- New entry? If not tracked, read the thread with
gmail_read_thread to get the recipient, subject, and sent date. Determine the follow-up window from which label it was found under (3d, 7d, or 14d). Add to tracking.json with status watching.
- Check for reply. Read the thread. If there's a message from someone other than the user's configured email that was sent AFTER the original message, mark as
replied.
- Check the window. If no reply and today's date minus the sent date (or last follow-up date) exceeds the
followUpWindowDays, mark as follow-up-due.
Step 4: Draft follow-ups
For each email with status follow-up-due:
-
Search for prior correspondence. Use gmail_search_messages:
from:{recipientEmail} OR to:{recipientEmail}
Read the most recent 5 threads to build context about the relationship.
-
Draft the follow-up. Match the user's style — direct, warm but not desperate. Rules:
- Keep it short (3-5 sentences max)
- Reference the original email naturally
- Don't apologize or grovel
- Add a soft call to action ("Would love to find a time" / "Any thoughts on this?")
- If it's a second follow-up (followUpCount == 1), make it even shorter (2-3 sentences) and slightly more direct
-
Save as Gmail draft. Use gmail_create_draft:
to: the recipient
subject: "Re: {original subject}"
threadId: the original thread ID (so it appears as a reply in the same thread)
body: the drafted follow-up
-
Create a calendar reminder. Use gcal_create_event:
summary: "Review draft follow-up to {Recipient Name}"
description: Include the original subject line, a brief note about what the email was about, and "Draft is in your Gmail drafts — review and send if it looks good."
start: Tomorrow at the user's configured reminder time (default 7:00 AM)
end: 15 minutes after start
reminders: popup at 0 minutes
colorId: "6" (Tangerine — stands out)
-
Update tracking.json:
- Increment
followUpCount
- Set
lastFollowUpDate to today
- Set
draftId to the returned draft ID
- Set
calendarEventId to the returned event ID
- Update status to
draft-ready
Step 5: Handle escalation
For emails where followUpCount == 1 and the follow-up window has passed again with no reply:
- Draft a shorter, more direct second follow-up
- Mark status as
escalated
- Create another calendar reminder
For emails where followUpCount >= 2 and still no reply:
- Mark as
gone-cold
- Stop tracking (no more drafts or calendar events)
- Optionally mention in the calendar event: "{Name} has gone cold after 2 follow-ups"
Step 6: Report summary
After processing all emails, output a brief summary:
Follow-Up Tracker — {today's date}
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
New emails being tracked: {count}
Follow-ups drafted: {count}
Replies received: {count}
Gone cold: {count}
Still watching: {count}
Configuration
Read from the user's setup or use these defaults:
- Follow-up window: Determined by label (3d, 7d default, 14d)
- Timezone: America/New_York
- Reminder time: 7:00 AM
- User email: (set during /setup)
Important Rules
- Any message FROM the user's configured email is the user's; anything else is a reply.
- Never fabricate details about conversations that didn't happen. Only reference things actually present in the email threads.
- If the original email was very short or casual, keep the follow-up equally casual.
- If the original email was formal or detailed, match that tone.
- Always save the draft as a reply in the same thread so Gmail groups them together.
