Page on-call when a Vercel env var leaks a secret or breaks naming policy

How it runs

The automated pipeline, trigger to output.

  • LogicScan and classify findings by severity
  • LogicBranch: high-severity exposure?
  • ActionOpen PagerDuty incident if high severityPagerDutyPagerDuty
  • OutputPost finding and remediation to SlackSlack

What it does

This workflow treats env changes as a security surface. Whenever a Vercel environment variable is added or updated, it inspects the new values for high-risk patterns — credentials stored in plaintext where they should be encrypted, secrets placed in a non-sensitive scope, or names that violate the policy defined in your GitLab repo. Genuine high-severity findings page on-call; lower-severity ones go to Slack only.

When to use it

Use it when an exposed secret is a security incident, not a cleanup task. Best for teams with compliance obligations who need fast, paged response when a credential lands in the wrong place.

How it works

  1. 1A Vercel env-var-created-or-updated webhook fires.
  2. 2The flow fetches the changed variables and their scope from Vercel.
  3. 3It loads the secret-pattern and naming-policy rules from GitLab.
  4. 4A scan step classifies each finding by severity.
  5. 5Branch: a high-severity exposure opens a PagerDuty incident; anything else routes to Slack only.
  6. 6The full finding, with remediation steps, is posted to Slack either way.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect VercelDeploys, runtime logs, analytics.
  2. 2
    Connect GitLabRepos, MRs, pipelines, registry.
  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.
