Email Follow-up Tracker

Track sent emails awaiting replies and surface follow-up reminders when responses are overdue.

Language

Detect the user's preferred language from Personal Preferences. Respond entirely in that language.

Storage

All follow-up tracking data is stored in ~/Tandem/email/MEMORY.md under the section ## Pending Follow-ups.

Workflow

Step 1: Determine Action

AskUserQuestion: "What would you like to do?"
Options: [
  "Add a new follow-up to track",
  "Check status of pending follow-ups",
  "Send a follow-up email",
  "View all tracked items"
]

Step 2A: Add New Follow-up

Gather information (from email context or user input):

• Recipient name and email
• Subject line
• Date sent
• Expected response date (default: 3 business days from sent date)
• Brief context (one line — what was the email about)

AskUserQuestion: "When do you expect a reply?"
Options: ["Tomorrow", "Within 3 days", "Within a week", "Custom date"]

Write entry to ~/Tandem/email/MEMORY.md under ## Pending Follow-ups using the format from template.md.

Step 2B: Check Status

• Read the Pending Follow-ups section from ~/Tandem/email/MEMORY.md
• For each tracked item, check the inbox for replies from that sender on that subject
• Update status: Replied (found response), Overdue (past expected date, no reply), Waiting (not yet due)
• Present summary using template.md format

For overdue items:

AskUserQuestion: "You have [N] overdue follow-ups. What would you like to do?"
Options: [
  "Send follow-up to [most overdue sender]",
  "Extend deadline by 3 days",
  "Remove from tracking",
  "Send follow-ups to all overdue"
]

Step 2C: Send Follow-up

• Invoke email-draft with tone set to "Follow-up"
• Pre-populate context: original subject, date sent, what was requested
• The draft references the original email and politely asks for an update

Step 2D: View All

Display the full tracking table from template.md, sorted by status (Overdue first, then Waiting, then Replied).

Step 3: Cleanup

When a reply is received or user removes tracking:

AskUserQuestion: "Follow-up resolved. What should I do with this entry?"
Options: ["Remove from tracking", "Keep for reference", "Set new follow-up"]

Update ~/Tandem/email/MEMORY.md accordingly.

Proactivity — Integration Points

This skill is surfaced proactively in these situations:

• During email triage: If sent emails are found without replies after 3+ days, suggest tracking them
• During daily briefing: List overdue follow-ups as part of the morning summary
• After sending an email via email-draft: Offer to add follow-up tracking

Maximum 1 follow-up reminder per session unless user asks for more.

Memory

Memory is user-triggered only. The follow-up list itself is stored in MEMORY.md, but offer to remember:

• Default expected reply time for specific contacts
• Contacts who typically respond slowly (adjust default expectations)

Output Format

Follow template.md for the tracking table format.

Error Handling

• No pending follow-ups: "You have no emails being tracked. Want to add one?"
• Email connector unavailable: "I can't check for replies automatically. Want me to show you the tracking list so you can update manually?"
• MEMORY.md section missing: Create the ## Pending Follow-ups section automatically
