+# Slack Integration
+
+Scan Slack channels, DMs, and mentions for action items during the morning routine. This recipe addresses common pitfalls with the Slack MCP connector -- particularly stale data in channel scans and unreliable DM coverage -- using timestamp-gated reads and a two-pronged DM strategy.
+
+## Prerequisites
+
+A Slack MCP connector. Current options:
+
+- **Claude Cowork:** Built-in Slack connector. Provides channel reads, thread reads, search, and user profile lookup.
+- **Community MCP servers:** Check the [MCP server directory](https://github.com/modelcontextprotocol/servers) for alternatives.
+
+Your connector needs at minimum: `read_channel` (with timestamp filtering), `search` (with date modifiers), and `read_thread`.
+
+> **Parameter naming:** This recipe uses `oldest` as the timestamp filter parameter on channel reads, which matches the Slack Web API's `conversations.history` endpoint and the Claude Cowork connector. Community MCP servers may use different parameter names (e.g., `after`, `since`, `start_time`). Check your connector's documentation and adjust the vault file accordingly.
+
+## Configuration
+
+### 1. Create a Slack config section in your instruction file
+
+Add a section listing your priority channels and frequent DM contacts. This is the data the scanning routine uses -- keep it updated as your channels and contacts change.
+
+```markdown
+## Slack
+
+### Priority Channels
+
+Scan in this order during the morning routine:
+
+| Priority | Channel | ID | Notes |
+|----------|---------|-----|-------|
+| 1 | #leadership | `CXXXXXXXXXX` | Highest priority |
+| 2 | #operations | `CXXXXXXXXXX` | |
+| 3 | #finance | `CXXXXXXXXXX` | Always scan even without @mentions |
+| 4 | #access-requests | `CXXXXXXXXXX` | Flag pending requests |
+
+### Frequent DM Contacts
+
+Read these DM channels directly (search alone can miss DMs):
+
+| Contact | DM Channel ID |
+|---------|--------------|
+| Alice | `DXXXXXXXXXX` |
+| Bob | `DXXXXXXXXXX` |
+
+> To find a DM channel ID: open a DM with the person, then look at the
+> URL in Slack -- the `DXXXXXXXXXX` portion is the channel ID. Or use
+> `slack_read_channel` with their user ID.
+```
+
+### 2. Add Slack scanning to the daily routine
+
+Replace or extend the "Scan messaging" step in `Knowledge/Jesse-Guidelines/Start-of-Day-Routine.md`:
+
+```markdown
+- **Scan Slack** -- Use timestamp-gated reads. See
+  [[Knowledge/Jesse-Guidelines/Slack-Scanning-Guidelines]] for the
+  full approach. Key points:
+  - Calculate scan window from Dashboard.md's "Last updated" date
+    minus a 4-hour overlap buffer. Default to 96 hours if no date.
+  - Use `slack_read_channel` with the `oldest` timestamp for each
+    priority channel (listed in instruction file).
+  - Two-pronged DM scan: `to:me after:YYYY-MM-DD` search PLUS
+    direct reads of known DM channels.
+  - Dedup against Dashboard.md's Slack section before surfacing.
+```
+
+### 3. Create the detailed guidelines file
+
+Create `Knowledge/Jesse-Guidelines/Slack-Scanning-Guidelines.md` in your vault with the content from the [Vault File](#vault-file) section below.
+
+## Vault Structure
+
+One new file:
+
+```
+Knowledge/Jesse-Guidelines/Slack-Scanning-Guidelines.md
+```
+
+No new directories needed.
+
+## How It Works
+
+### The Problem
+
+Slack MCP connectors have two reliability issues that cause bad morning briefings:
+
+1. **Stale data in channel scans.** Broad search queries (or channel reads without timestamp filters) return a mix of old and new messages. Without context about what was already surfaced in previous sessions, the agent presents week-old discussions as if they're new. This wastes time and erodes trust.
+
+2. **Missed DMs.** The `to:me` search modifier is unreliable -- it can miss DMs entirely, especially from less frequent contacts. If DMs are your only scan method, you'll silently drop action items.
+
+3. **Invisible thread replies.** `slack_read_channel` with an `oldest` timestamp only returns top-level messages posted after that timestamp. Thread replies on older parent messages -- even brand-new ones with @mentions -- are completely invisible to channel reads. If someone replies to a week-old thread with "@you please review this," the channel scan won't see it.
+
+### The Solution
+
+The vault file below implements two techniques to solve these problems:
+
+**Timestamp-gated channel reads.** Instead of broad search queries, use `slack_read_channel` with an `oldest` timestamp derived from your Dashboard's last-updated date. This returns exactly the messages posted since your last session -- no stale data. The scan window adapts automatically: a normal weekday gets ~28 hours of lookback, a long weekend gets ~96 hours, because it's anchored to when you last ran the routine rather than a fixed window.
+
+**Two-pronged DM scanning.** A `to:me` search catches DMs from anyone, but misses some messages. Direct reads of known DM channels never miss messages, but only cover contacts you've listed. Using both together eliminates the gap.
+
+**Mention search for thread replies.** The `to:me` search that's already part of DM scanning (Prong 1) does double duty: it also catches @mentions in thread replies on older parent messages. The key is to check those search results for thread replies in channels (where `thread_ts` differs from `message_ts`), not just DMs. For any thread reply found, `slack_read_thread` pulls the full context. This closes the gap that channel reads alone can't cover.
+
+The vault file also covers dedup against Dashboard.md (so tracked items don't resurface), thread context handling, and subagent delegation patterns. See the [Vault File](#vault-file) section for the complete implementation.

+# Slack Scanning Guidelines
+
+Reliable Slack scanning during the morning routine. Use timestamp-gated
+channel reads and two-pronged DM scanning to avoid stale data and missed
+messages.
+
+## Scan Window
+
+1. Parse Dashboard.md's "Last updated" line for the previous session date.
+2. Convert to Unix timestamp, subtract 4 hours (overlap buffer).
+3. If no date available, default to 96 hours ago.
+4. Use this timestamp as `oldest` on all `slack_read_channel` calls.
+
+Compute the timestamp (replace YYYY, M, D, H with values parsed from
+Dashboard.md's "Last updated" line):
+
+```bash
+python3 -c "
+from datetime import datetime, timezone, timedelta
+# Replace these with the actual date/time from Dashboard.md
+last_session = datetime(YYYY, M, D, H, 0, 0, tzinfo=timezone.utc)
+buffered = last_session - timedelta(hours=4)
+print(f'{buffered.timestamp():.0f}')
+"
+```
+
+## Channel Reads
+
+For each priority channel (listed in instruction file), call:
+
+```
+slack_read_channel(
+  channel_id="{ID}",
+  oldest="{timestamp}",
+  limit=50,
+  response_format="concise"
+)
+```
+
+If pagination is indicated, fetch the next page.
+
+## DM Scanning (Two-Pronged)
+
+### Prong 1: Search
+
+```
+slack_search_public_and_private(
+  query="to:me after:YYYY-MM-DD",
+  sort="timestamp",
+  sort_dir="desc",
+  limit=20,
+  include_context=true
+)
+```
+
+Use the previous session date minus 1 day.
+
+### Prong 2: Direct DM Reads
+
+For each frequent DM contact (listed in instruction file), call
+`slack_read_channel` with their DM channel ID and the same `oldest`
+timestamp.
+
+Direct reads catch messages that `to:me` search misses.
+
+## Thread Replies and @Mentions
+
+### The gap: thread replies on older messages
+
+`slack_read_channel` with `oldest` only returns **top-level channel
+messages** posted after the timestamp. It does **not** return thread
+replies on older parent messages, even if the reply itself is new.
+This means @mentions in threads on older posts will be missed by
+channel reads alone.
+
+**Example:** You post a message on Monday. Someone replies in that
+thread on Thursday with "@you can you review this?" The Thursday
+channel scan (with `oldest` set to Wednesday) will NOT see this
+reply because the parent message is from Monday.
+
+### Fix: Add a mention search pass
+
+After all channel reads and DM scans, run an additional search for
+@mentions:
+
+```
+slack_search_public_and_private(
+  query="to:me after:YYYY-MM-DD",
+  sort="timestamp",
+  sort_dir="desc",
+  limit=20,
+  include_context=true
+)
+```
+
+This overlaps with the DM search (Prong 1) and can be combined into
+a single search. The key point is that results must be checked for
+**thread replies in channels**, not just DMs. For any result that is
+a thread reply (`thread_ts` differs from `message_ts`), use
+`slack_read_thread` to get full context before summarizing.
+
+### Enriching channel read results
+
+When a channel message has replies or someone tags you with a vague
+message ("^", "+1", etc.), use `slack_read_thread` with the
+`message_ts` to get full context before summarizing.
+
+## Dedup
+
+Before surfacing any item:
+
+1. Check Dashboard.md Slack section for existing entries.
+2. Same item + no state change = skip.
+3. Same item + state change = surface with delta noted.
+
+## Known Quirks
+
+- `slack_search_channels` may not find Slack Connect or shared channels.
+  Use `slack_search_public_and_private` with `in:channel-name` as
+  fallback, or read by channel ID directly.
+- `to:me` search can return empty results even when DMs exist. This is
+  why Prong 2 (direct reads) exists.
+- Empty search results don't mean the connector is broken. Verify with
+  a `slack_read_channel` call on a known-active channel.
+- Formatted dates in search results can appear shifted. Prefer the
+  Unix `message_ts` for determining when a message was posted.
+- Thread replies on old messages are invisible to channel reads.
+  `slack_read_channel` with `oldest` only returns top-level messages.
+  New thread replies (even with @mentions) on parent messages older
+  than the scan window won't appear. The `to:me` mention search pass
+  catches these.
+
+## Maintaining the Contact List
+
+When a new frequent DM contact is discovered, add their DM channel ID
+to the instruction file's Frequent DM Contacts table. To find a DM
+channel ID, use `slack_read_channel` with the person's user ID.
+````
+
+## Tips and Gotchas
+
+**The `to:me` search is unreliable for DMs.** This was the single biggest source of missed items. The two-pronged approach (search + direct reads) eliminated the problem. If you only do one thing from this recipe, add direct DM channel reads.
+
+**Don't use a fixed scan window.** A 24-hour window misses things after weekends. A 96-hour window surfaces too much stale data on weekdays. Anchoring to the Dashboard date adapts automatically.
+
+**The 4-hour overlap buffer matters.** Without it, messages posted near the end of the previous session can fall through the crack between "last session ended" and "new session's oldest timestamp."
+
+**Subagents need context to avoid the stale-data problem.** If you delegate Slack scanning to a subagent and don't pass the timestamp and Dashboard context, the subagent will use broad searches and present old messages as new. This is the failure mode that motivated this recipe.
+
+**Keep your channel list and DM contacts list updated.** When you start monitoring a new channel or notice DMs from a new frequent contact, add them to the instruction file. The scanning routine only checks what's listed.
+
+**Thread replies on old messages are invisible to channel reads.** This is the subtlest gap. Someone can @mention you in a thread on a week-old message and `slack_read_channel` won't return it, no matter what `oldest` is set to. The `to:me` mention search catches these -- make sure you're checking search results for thread replies (where `thread_ts` differs from `message_ts`) and pulling full thread context with `slack_read_thread`.
+
+**Slack's "Save for Later" list has no API.** Slack retired the stars/reminders endpoints in 2023 when they launched "Save for Later." There is no way to read this list programmatically. Workaround: manually review your Later list and drop anything actionable into `Inbox/` or `Knowledge/Reminders/`.
