+1. Treat this as expected behavior for Dependabot PRs
+2. If you want Neon preview branches on non-Dependabot PRs, verify both `NEON_API_KEY` and `NEON_PROJECT_ID` are configured

+### Workflow Skips Neon Jobs on Dependabot or Unconfigured PRs
+
+**Behavior**: `create_neon_branch` and `delete_neon_branch` are skipped instead of failing.
+
+**Why it happens**:
+1. GitHub does not expose repository secrets to Dependabot-triggered `pull_request` workflows
+2. The repository is missing `NEON_API_KEY` or `NEON_PROJECT_ID`
+
+**What to do**:
+1. No action is required for Dependabot PRs; skipping is expected
+2. For regular PRs, add `NEON_API_KEY` and `NEON_PROJECT_ID` in repository Actions settings if Neon preview branches should run
