What it does

Handles the specific case of a fixed bug coming back. Rather than filing a fresh duplicate, it reopens the original ticket with proof of regression and escalates only when the recurrence is severe.

When to use it

For mature teams that mark Sentry issues resolved on deploy and need to know immediately when a fix regresses in production. Use it to keep one durable ticket per bug across its full lifecycle.

How it works

  1. 1Sentry fires a webhook on a regression (a resolved issue that recurred).
  2. 2The flow locates the closed Linear issue previously linked to that Sentry group.
  3. 3It reopens the Linear issue and posts the new occurrence, the release where it returned, and a diff against the release that resolved it.
  4. 4Branch on severity: if events-per-minute or user-impact crosses the bar, it triggers a PagerDuty incident; otherwise it just flags the issue urgent.
  5. 5It notifies the relevant Slack channel with the reopened ticket and regression context.
  6. 6It updates the Sentry group status to reflect the reopened ticket.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect SentryErrors, performance, releases.
  2. 2
    Connect LinearIssues, projects, cycles, triage.
  3. 3
    Connect PagerDutyIncidents, on-call, escalations.
  4. 4
    Connect SlackChannels, DMs, threads, mentions.
  5. 5
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  6. 6
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  7. 7
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
