Email drafter

Purpose

Process the user's unread emails into draft replies written in their voice. The twin fetches emails, filters out those that do not need a response, drafts replies using the user's voice profile and business knowledge (including Notion), and saves each draft to Gmail. Drafts are never sent -- the user reviews and sends them manually.

Config loading

Before starting the steps below:

1. Read ~/.agents/config/voice-profile.yaml for voice and tone rules
2. Read all .yaml files in ~/.agents/config/business-context/ for domain knowledge
3. If any required config is missing, stop and report the expected path

Steps

Step 1: Fetch unread emails

Skill: gmail-fetch Input: Query is:unread (or a user-provided query), max_results 20 (or user-provided), include_threads true Output → emails

Read and follow the instructions in ~/.agents/skills/gmail-fetch/SKILL.md. Fetch unread emails with thread context. If no emails are returned, report that there is nothing to process and stop (this is not an error).

Step 2: Triage emails

Skill: none (inline judgement) Input: emails from step 1 Output → actionable_emails

Review each email in emails and decide whether it needs a reply. Split the list into two groups:

Skip (no draft needed):

• Newsletters and mailing lists (look for List-Unsubscribe headers, noreply@ or no-reply@ senders, marketing/bulk labels)
• Automated notifications from services (e.g. GitHub, Stripe, calendar systems, monitoring alerts)
• Calendar invitations and RSVP confirmations
• Emails sent by the user themselves
• Threads where the user has already replied (the most recent message in the thread is from the user)
• Purely informational messages with no question, request, or action needed

Include (draft a reply):

• Direct emails from a person that contain a question, request, or require acknowledgement
• When in doubt, include the email -- it is better to draft an unnecessary reply (the user can delete it) than to miss one that needs a response

For each skipped email, record the subject, sender, and reason for skipping.

If no emails need a reply after triage, present the triage summary and stop.

Step 3: Draft replies in the user's voice

Skill: email-voice-draft Input: Each email from actionable_emails (one at a time), plus any user-provided reply_guidance Output → draft_replies

For each email in actionable_emails, read and follow the instructions in ~/.agents/skills/email-voice-draft/SKILL.md.

Pass the email data as the email thread input:

• from: the sender
• subject: the subject line
• body: the most recent message body
• thread_history: prior messages in the thread (from thread_messages)
• thread_id: the Gmail thread ID
• message_id: the Gmail message ID (for reply threading)

If the user provided reply_guidance, pass it through.

The email-voice-draft skill will load the voice profile and business context (already in context from the preamble), search Notion for relevant knowledge, and compose the reply.

Collect the draft_reply output from each invocation. If drafting fails for one email, record the error and continue with the remaining emails.

Step 4: Save drafts to Gmail

Skill: gmail-draft Input: Each draft_reply from step 3 (one at a time) Output → draft_confirmations

For each draft_reply, read and follow the instructions in ~/.agents/skills/gmail-draft/SKILL.md.

Pass the following fields:

• to: recipient address
• subject: reply subject line
• body: the draft reply text
• thread_id: Gmail thread ID (if present, so the draft is threaded correctly)
• in_reply_to: the message ID for reply headers (if present)

Collect the confirmation (draft_id, summary) for each. If saving fails for one draft, record the error and continue with the remaining drafts.

Output

Present a summary to the user:

Drafts created: list each draft with the recipient, subject, and any Notion pages that informed the reply.

Skipped: list each skipped email with the sender, subject, and reason.

Errors (if any): list any emails where drafting or saving failed, with the error detail.

Remind the user that all drafts are in their Gmail drafts folder for review. Nothing has been sent.
