Fetch Slack activity for: $ARGUMENTS

Step 1 — Resolve date and Slack user ID

Date: Use the Skill tool to invoke work-date-resolver with args $ARGUMENTS. Parse DATE from the output.

Slack user ID: If SLACK_USER_ID is provided in context, use it directly. Otherwise:

1. Run gh api user --jq '{email: .email, name: .name}' to get the GitHub user's email and name.
2. Call slack_search_users with query: <email>. Find the matching entry and store its id as SLACK_USER_ID.
3. If email lookup returns no match, retry with query: <name>.

Step 2 — Search Slack (both in parallel)

Use slack_search_public_and_private:

Sent messages:

• query: "from:<@SLACK_USER_ID> on:DATE"

Mentions:

• query: "<@SLACK_USER_ID> on:DATE"

Filter out:

• Bot messages and automated notifications
• Single-emoji reactions and reaction-only threads
• Off-topic / non-work channels (e.g. #random, #general-social)

Step 3 — Output

Emit exactly in this format:

SLACK_RESULT
DATE: <DATE>

HIGHLIGHTS (N):
- **#channel** — thread summary (one line per distinct thread/topic)

Combine sent and mentions into a single de-duplicated list, grouped loosely by thread. If nothing substantive: emit HIGHLIGHTS (0): (none).
