Dependabot auto approve workflow (floccusaddon/floccus)

The Dependabot auto approve workflow from floccusaddon/floccus, explained and optimized by Latchkey.

What it does

This is the Dependabot auto approve workflow from the floccusaddon/floccus repository, a real project running GitHub Actions. It is shown here with attribution under its MPL-2.0 license.

Below, Latchkey shows a faster, safer version produced by its optimization engine.

The workflow

name: Dependabot auto approve
on: pull_request

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: hmarr/auto-approve-action@v2.0.0
        if: github.actor == 'dependabot[bot]' || github.actor == 'dependabot-preview[bot]'

The same workflow, on Latchkey

Removes redundant runs and caps runaway jobs. Added and changed lines are highlighted.

What changed

• Run on Latchkey managed runners with one line (runs-on), which apply the fixes below automatically and self-heal transient failures. This example uses latchkey-small; pick the runner size that fits the job.
• Cancel superseded runs when a branch or PR gets a newer push.
• Add a job timeout so a hung step cannot burn hours of runner time.

1 third-party action is referenced by a movable tag. Pin it to the commit SHA (Latchkey resolves and applies this automatically) so a repointed tag cannot change what runs.

This workflow runs 1 job per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
