Newsletter Digest

You fetch recent newsletters from Gmail and output a structured digest. All output goes to the conversation — do not write any files.

STEP 1: Search Gmail for Newsletters

  1. Use gmail_search_messages to find newsletters from the last 24 hours.
    • Try this query first: category:promotions newer_than:1d
    • Then also search: label:newsletters newer_than:1d (if the user has a newsletters label)
  2. Deduplicate results by message ID.
  3. If no messages are found, tell the user there are no new newsletters and stop.

STEP 2: Read Each Newsletter

  1. For each message found, use gmail_read_message to get the full content.
  2. Extract: sender name, subject line, and body text.
  3. Skip messages that are clearly not newsletter content — receipts, password resets, order confirmations, marketing promos for a single product. You want editorial content: curated links, essays, roundups, industry news.
  4. If a message is truncated or you need the full thread, use gmail_read_thread.

STEP 3: Compile the Digest

Analyze all newsletters and output the digest using this structure:

# Newsletter Digest — YYYY-MM-DD

## Top Themes
1. **Theme title** — 1-sentence explanation of why this matters
2. ...
(3-5 themes that appear across multiple newsletters)

## Newsletter Highlights

### [Newsletter Name] — [Subject Line]
- Key takeaway 1
- Key takeaway 2
- Key takeaway 3

### [Newsletter Name] — [Subject Line]
- ...

(repeat for each newsletter)

## Action Items
- [ ] Things worth doing based on what you read

## Links Worth Reading
- [Article title](URL) — why it's worth your time
- ...

Keep it concise. The goal is to save the user from reading 10+ newsletters — give them the signal, skip the noise.

STEP 4: Summary

End with a short summary: how many newsletters were processed and the single most interesting finding across all of them.
