Pull request overview
This PR introduces automated approval and merging of Dependabot pull requests by adding a new GitHub Actions workflow. The workflow automatically approves and enables auto-merge for Dependabot PRs in the 1c-syntax/bsl-language-server repository.
- Adds a new workflow file for Dependabot automation
- Configures automatic PR approval and auto-merge for dependency updates
- Restricts workflow execution to Dependabot PRs in the specific repository

13-17: Consider using the fetched metadata for conditional auto-merge.The Dependabot metadata is fetched but never used. You could leverage this data to implement smarter auto-merge logic, such as:
- Only auto-merge patch updates (
update-type: version-update:semver-patch)- Skip auto-merge for major version updates
- Handle different dependency types differently
🔎 Example: Only auto-merge patch and minor updates:
- name: Enable auto-merge for Dependabot PRs + if: steps.metadata.outputs.update-type == 'version-update:semver-patch' || steps.metadata.outputs.update-type == 'version-update:semver-minor' run: gh pr merge --auto --merge "$PR_URL" env: PR_URL: ${{github.event.pull_request.html_url}} GH_TOKEN: ${{secrets.GITHUB_TOKEN}}

4-6: LGTM!Permissions are correctly configured for approving and merging pull requests.
18-22: Self-approval with GITHUB_TOKEN may not work in all configurations.Some repository configurations prevent the workflow's GITHUB_TOKEN from approving its own PRs. If auto-merge fails, you may need to:
- Create a GitHub App or use a Personal Access Token (PAT) with appropriate permissions
- Configure repository settings to allow workflow approvals
Test this workflow with an actual Dependabot PR to ensure the approval succeeds. If it fails, consider using a GitHub App or PAT stored in secrets.
23-27: Auto-merge will wait for required status checks.The
--auto --mergeflags enable auto-merge with a merge commit strategy. The PR will automatically merge once all required status checks pass and approval requirements are met. This is the expected behavior.If you prefer squash or rebase merge strategies, use
--squashor--rebaseinstead of--merge.
8-11: Ensure branch protection rules are compatible with auto-merge.The workflow approves and auto-merges Dependabot PRs, which requires branch protection rules to be configured appropriately. Auto-merge will fail if your branch protection rules require multiple approvers (>1) or mandate reviews from code owners. Required status checks are fine and expected—auto-merge waits for them to pass before merging.

2-2: Security concern: Usepull_request_targetinstead ofpull_request.This issue has already been flagged in a previous review. The
pull_requesttrigger runs in the context of the PR head branch, which poses security risks when combined with write permissions. Consider usingpull_request_targetwith specific activity types as suggested.

13-17: Consider using the metadata outputs for filtering.The Dependabot metadata is fetched but not used in the workflow. You could leverage the outputs to add safety guardrails, such as only auto-merging patch updates or filtering by dependency type.
Example: Auto-merge only patch updates
- name: Dependabot metadata id: metadata uses: dependabot/fetch-metadata@d7267f607e9d3fb96fc2fbe83e0af444713e90b7 with: github-token: "${{ secrets.GITHUB_TOKEN }}" - name: Approve a PR if: steps.metadata.outputs.update-type == 'version-update:semver-patch' run: gh pr review --approve "$PR_URL" env: PR_URL: ${{ github.event.pull_request.html_url }} GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} - name: Enable auto-merge for Dependabot PRs if: steps.metadata.outputs.update-type == 'version-update:semver-patch' run: gh pr merge --auto --merge "$PR_URL" env: PR_URL: ${{ github.event.pull_request.html_url }} GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}

18-27: Implementation looks correct.The approval and auto-merge steps are properly configured:
- Correct use of
ghCLI commands- Proper environment variable setup with
PR_URLandGH_TOKEN- Expression syntax is consistent with GitHub Actions best practices (the spacing issue mentioned in past comments appears resolved)
