Open a PagerDuty incident when a blocked promote keeps regressing

How it runs

The automated pipeline, trigger to output.

  • LogicDecide if force-promote or repeat regression warrants escalation
  • ActionOpen PagerDuty incident for on-callPagerDutyPagerDuty
  • OutputUpdate Linear issue with incident linkLinearLinear

What it does

This workflow turns a blocked Vercel promote into accountable follow-up. When the synthetic gate rejects a promotion, it files a Linear issue capturing the failing metrics and the offending deployment. If the workflow sees that deployment force-promoted to production anyway, or the same regression recur within the window, it escalates by opening a PagerDuty incident so on-call owns the live degradation.

When to use it

Use it when a blocked promote needs a paper trail and an escalation path, not just a Slack ping that scrolls away. Good for teams with override authority who still want every override to create an incident.

How it works

  1. 1A blocked-promote event from the synthetic gate triggers the workflow with the deployment ID and failing metrics.
  2. 2A Linear issue is created with the metric diff and a link to the preview.
  3. 3The workflow checks the Vercel API to see whether that deployment later reached production.
  4. 4A branch evaluates whether it was force-promoted or the regression repeated.
  5. 5If escalation is warranted, a PagerDuty incident is opened and tagged to on-call.
  6. 6The Linear issue is updated with the incident link to close the loop.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect VercelDeploys, runtime logs, analytics.
  2. 2
    Connect LinearIssues, projects, cycles, triage.
  3. 3
    Connect PagerDutyIncidents, on-call, escalations.
  4. 4
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.

Run this workflow in your colony.
