/update-threads

Re-read all tracked threads whose last_read_time is older than 1 hour and update their files in-place.

Steps:

1. Read Threads.txt — parse all entries.

2. Identify stale entries — collect every entry where last_read_time is more than 1 hour before the current time.

3. Skip if none — if no stale entries exist, report "All threads are up to date." and stop.

4. Spawn parallel Explore agents — launch one Explore agent per stale thread concurrently. Each agent must:

   a. Use the Slack MCP tool to re-fetch the full thread.

   b. Open the existing threads/<filename>.md.

   c. Merge updates (do not duplicate existing content):

   • Refresh Last-read-time to now.
   • Add new Content bullet points for messages that appeared after the previous last_read_time. Do not re-add existing points.
   • Append new rows to the References table for any links not already present.
   • Re-evaluate and rewrite the Impactful section based on the full thread.
   • Add the Conclusion section if the last reply is now > 1 month old; remove it if the thread has become active again.

   d. Write the updated file back.

   e. Return: { url, filename, new_last_read_time }.

5. Update Threads.txt — overwrite last_read_time for each refreshed entry.

6. Report to user — list the files updated and the count of new messages incorporated per thread.
