Auto-Unblock Issues When Slack Reactions Clear

When a blocker is resolved, your team signals it with a Slack reaction. Notis removes the Blocked label from the corresponding Linear issue automatically, keeping status in sync.

Trigger

Action

Remove label from Linear issue

Removes a specified label from an existing linear issue using their ids; successful even if the label isn't on the issue.

Why this helps

Blocked issues in Linear often stay marked as blocked long after the blocker is resolved, because nobody remembers to update the label. Neurodivergent founders lose track of what's actually blocked.

  • Keep issue status current by reflecting real-world progress
  • Automatically unblock issues without manual label management
  • Use natural Slack reactions to drive Linear updates
  • Reduce manual status maintenance

Setup

Build it in a few focused steps.

  • 1Connect Slack and Linear to Notis.
  • 2Tell Notis: 'When someone removes a specific reaction from a Slack message, remove the Blocked label from the matching Linear issue' or use the portal.
  • 3Provide the prompt: 'When the blocking-fixed reaction is removed from a Slack message, find the referenced Linear issue and remove the Blocked label.'
  • 4Choose your trigger reaction and confirm your Linear team.
  • 5Test by adding and removing the reaction on a Slack message to verify the label behavior.

Questions about this workflow

What if the issue doesn't have the Blocked label?

Notis handles this gracefully. It will attempt to remove the label if it exists; if it doesn't, nothing happens.

Can I use this for other label types besides Blocked?

Yes. Customize your prompt to remove any label type based on any emoji reaction.

Does this work if the blocker is only partially resolved?

The automation is simple: reaction removed = label removed. If you need conditional logic, mention that in your prompt and Notis can adapt.
