Why this helps
When a blocker status changes, the related readiness check can be overlooked during the handoff.
- Prompt a fresh connected-agent list when a blocker signal changes.
- Support cleaner handoffs during resolution.
- Keep a small follow-up from relying on memory.
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.
- 3Write one plain-language instruction asking Notis to list connected agents when the chosen blocker reaction is removed from a relevant message.
- 4Choose the Slack reaction-removed trigger, set its available channel and emoji filters, and choose a run-report channel.
- 5Test by removing the agreed reaction from a real blocker message.
Questions about this workflow
Does removing the reaction confirm that the blocker is fixed?
No. It is only a cue to retrieve the current connected-agent list.
Can the workflow start a build to verify resolution?
No. The available Buildkite action lists agents but does not trigger builds.
