P activity digest

Activity Digest

Aggregate and summarize recent communication activity from Slack messages and meeting recordings (Fireflies). Produces a structured summary with action items, mentions, and key decisions.

When to Use

• User asks for Slack activity summary
• User wants meeting highlights or action items
• User asks "what was discussed" or "what happened on Slack"
• User wants to find messages where they were mentioned
• Producing communication portions of a daily/weekly report

Prerequisites

• Slack MCP server configured and authenticated
• Fireflies MCP server configured (optional, for meeting transcripts)

Workflow

Step 1: Determine Scope

Ask the user if not clear:

• Time range: today, yesterday, past N days, specific date
• Sources: Slack only, Fireflies only, or both
• Focus: all activity, mentions only, action items only, specific channels/topics

Shared context (resolved before dispatch):

• DATE_START: start date (YYYY-MM-DD)
• DATE_END: end date (YYYY-MM-DD)
• SOURCES: which sources to query
• FOCUS: filter mode

Steps 2 and 3 are independent data sources. Dispatch both concurrently (parallelize if possible). If your platform supports parallel subagents, launch one per source. Otherwise, query each sequentially.

Step 2: Gather Slack Activity (parallelize if possible)

Use the Slack MCP tools in this order:

1. Identify user: Call slack_read_user_profile() (no args) to get the current user's ID.
2. Dispatch all Slack searches in parallel.
3. Search for mentions: Call slack_search_public_and_private with query "from:me" and date-scoped query for the target period to find the user's own messages
4. Search for mentions of user: Call slack_search_public_and_private with the user's name or handle to find where others mentioned them
5. Channel context (optional): If a specific channel is requested, use slack_read_channel on that channel for the time period

Combine results and deduplicate.

Step 3: Gather Meeting Activity

If Fireflies is available and in scope:

1. Search meetings: Call fireflies_get_transcripts with date filters for the target period
2. For each meeting returned, call fireflies_get_summary in parallel (parallelize if possible) — each call is independent.
3. Get summaries: For each relevant meeting, call fireflies_get_summary to retrieve action items, keywords, and overview
4. Deep dive (optional): If the user asks about a specific meeting, call fireflies_get_transcript for full conversation content

If Fireflies is unavailable, proceed with Slack data only and note the omission in the output.

SYNC: After all data sources return, merge results into a unified collection before synthesis. If a source was unavailable, proceed with available data.

Deduplicate: Before synthesis, deduplicate across sources — the same discussion may appear in both Slack threads and Fireflies meeting notes. Use thread timestamps and meeting IDs as primary keys to merge overlapping records.

Step 4: Synthesize and Format

Produce a structured summary organized by priority:

## Activity Digest - [Date Range]

### Action Items

- [action item from meeting or Slack thread]
- [action item with @assignee if identifiable]

### Key Decisions

- [decision made in meeting or Slack discussion]

### Mentions & Requests

- [someone asked/mentioned you about X in #channel]

### Meeting Highlights

- **[Meeting Title]** — [1-2 sentence summary]
  - Key topics: [topic1], [topic2]

### Slack Activity Summary

- Participated in N threads across [channels]
- [Notable thread summary]

Adapt the format:

• If only Slack: omit Meeting Highlights section
• If only Fireflies: omit Slack Activity section
• If action-items-only: show only the Action Items section

Step 5: Output

• If the user specifies a file path, write to that file
• If the user is composing a daily report, provide the content for insertion
• Otherwise, display directly in the conversation

Tips

• When searching Slack, use date qualifiers in the query: "after:2026-02-16 before:2026-02-17"
• For meeting summaries, the fireflies_get_summary tool is much faster than fireflies_get_transcript — use summary first, transcript only when needed
• If Slack search returns too many results, narrow by channel or conversation type
• Deduplicate between Slack and meeting notes — the same discussion may appear in both

Examples

Example 1: Yesterday's activity

User: "summarize my Slack activity yesterday"
Action: Search Slack messages for yesterday, find mentions, format as digest

Example 2: Meeting action items

User: "what are action items from today's meetings?"
Action: Query Fireflies for today, get summaries, extract action items

Example 3: Full digest for daily report

User: "give me activity digest for today to add to my daily report"
Action: Query both Slack and Fireflies, produce combined summary, write to daily report file

Example 4: Specific mention search

User: "search Slack for messages about me this week"
Action: Search with user's name/handle for past 7 days, summarize findings
