SECOPS

Pull Request Secret Gate that Blocks Merge Until Cleared

On every pull request, scans the changed files for secrets and posts a blocking status check; if a secret is detected it fails the check, comments the exact location.

How it runs

The automated pipeline, trigger to output.

  • TriggerPull request opened or updatedGitHubGitHub
  • LogicScan PR diff for committed secrets
  • ActionSet passing or failing commit status checkGitHubGitHub
  • ActionPost review comment with masked match locationGitHubGitHub
  • OutputAssign remediation ticket to PR author in LinearLinearLinear

What it does

This workflow acts as a required status check on pull requests. It scans the PR diff for embedded credentials and sets the commit status to failure when one is present, preventing merge until the developer removes the secret and re-pushes.

When to use it

Use it when you want to stop secrets before they ever land on the default branch. Unlike the push scanner, this is a pre-merge gate, so the bad code never enters the protected history in the first place.

How it works

  1. 1A GitHub pull_request event (opened or synchronize) triggers the run.
  2. 2A logic step diffs the PR and tests each added line against secret detectors.
  3. 3If no secret is found, an action sets the commit status to success so merge is allowed.
  4. 4If a secret is found, an action posts a failing commit status plus a review comment pinpointing the file and line with the value masked.
  5. 5A Linear ticket is created and assigned to the PR author with a remediation checklist as the final output.

Set it up

What you configure once, before turning it on.

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