Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Important messages blend into a busy channel, forcing a founder to repeatedly explain which items need attention first.
- Use a shared visual signal for a supplied priority class
- Avoid adding a reaction when the target Slack message is not identified
- Keep triage lightweight for the team
