Why this helps
A blocker can be acknowledged in Slack without a clear next action or owner for checking agent availability.
- Attach an initial check to the team's blocker signal.
- Reduce extra coordination to begin triage.
- Keep availability context close to the marked message.
Setup
Build it in a few focused steps.
- 1Connect Slack and Buildkite to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3In one plain-language instruction, tell Notis to list connected agents when the chosen reaction marks a Buildkite agent availability blocker.
- 4Choose the Slack reaction-added trigger, set its available channel and emoji filters, and choose a channel for run reports.
- 5Test by adding the agreed reaction to a real blocker message.
Questions about this workflow
Does this take action on the blocker?
It only lists connected agents. It cannot trigger or restart a build.
How can the workflow avoid unrelated reactions?
Use the available channel and emoji filters and specify the relevant blocker context in the instruction.
