ci: auto-merge safe Dependabot updates for the website by manish-9245 · Pull Request #155 · opensawce/kaasu

manish-9245 · 2026-10-31T08:09:33Z

What

Dependabot PRs for /web (npm) that are patch or minor are approved and set to squash auto-merge once required checks pass. Major updates, GitHub Actions updates and anything outside /web still need a human.

Closes #85

Notes

This re-lands #86. Its merge commit 76a6289 is not an ancestor of main (main was rebuilt after the stacked PRs), so both the workflow and the web.yml changes are missing from the tree today. This is the same change with three fixes:

dependabot/fetch-metadata is pinned to a 40-char SHA, as scripts/check-pins.sh requires. ci: auto-merge patch and minor Dependabot updates for the website #86 used @v2.
The scope guard reads the changed file list and requires every path to start with web/, instead of trusting package-ecosystem == npm_and_yarn. A future npm entry outside /web would otherwise auto-merge.
The CODEOWNERS ownerless entries now come after *. The last matching pattern wins, so ci: auto-merge patch and minor Dependabot updates for the website #86's placement (before *) left the catch-all in force and the web files still code-owned.

web.yml now runs on every pull request (no path filter) and its job is renamed web-test, because go.yml already owns the check name test and required checks match by name.

After merge, one repo setting remains (it needs to land in the same step, otherwise auto-merge can merge before CI finishes):

gh api -X PUT repos/opensawce/kaasu/branches/main/protection/required_status_checks \
  -f strict=false \
  -f 'contexts[]=test' -f 'contexts[]=lint' -f 'contexts[]=web-test' \
  -f 'contexts[]=analyze (javascript-typescript)' -f 'contexts[]=analyze (actions)' \
  -f 'contexts[]=pins' -f 'contexts[]=title'

How to verify: #151 (@astrojs/starlight 0.42.6 → 0.42.7) is a patch bump and should approve + auto-merge. #149–#154 are Actions or major bumps and must stay open for a human.

Summary by CodeRabbit

Chores
- Eligible non-major web dependency updates from Dependabot can now be approved and squash-merged automatically.
- Pull requests now run the web checks regardless of which files they change.
- Deployments are skipped for pull requests from forks and Dependabot.

Re-lands #86, which was dropped when main was rebuilt: the workflow and web.yml changes are not in main's history. Only /web npm patch and minor bumps are approved and set to squash auto-merge. The workflow checks every changed path is under web/ rather than trusting the ecosystem name, and never checks out PR code. CODEOWNERS gains ownerless entries for the two web package files, placed after the catch-all because the last matching pattern wins.

Walkthrough

The web pull-request workflow now runs without path filters and excludes Dependabot pull requests from deployment. A new workflow approves and enables squash auto-merge for qualifying Dependabot updates that only change files under web/. CODEOWNERS adds ownerless rules for the web package files.

Changes

Web Dependabot automation

Layer / File(s)	Summary
Web pull-request checks and deployment `.github/workflows/web.yml`	The pull-request trigger no longer uses path filters. The test job is now `web-test`, and deployment excludes pull requests by `dependabot[bot]` as well as pull requests from forks.
Dependabot update eligibility and merge `.github/CODEOWNERS`, `.github/workflows/dependabot-automerge.yml`	CODEOWNERS adds ownerless rules for the web package manifest and lockfile. The new workflow checks the PR source, changed paths, ecosystem, and update version. It approves qualifying updates when they are not already approved and enables squash auto-merge when none exists.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Moderate · up to 62ab8

As written, the Dependabot auto-merge workflow fails at its first GitHub CLI call, so the automation the PR is meant to deliver will not work. The deploy exclusion for Dependabot PRs can also be bypassed when a person triggers the event. Fix the repository context before merging.

Architecture risk: Low · up to 62ab8

The changed surface does not map to a changed system, dependency edge, entrypoint, or external dependency.

Review details

Before / after behavior

observed — Modified behavior in .github/CODEOWNERS: Adds ownerless CODEOWNERS rules for the website package manifest and lockfile after the catch-all rule.
observed — Modified behavior in .github/workflows/dependabot-automerge.yml: Adds the workflow trigger, write permissions, per-PR concurrency, and job conditions restricting execution to Dependabot-authored PRs from the same repository in opensawce/kaasu. The job fetches Dependabot metadata.
observed — Modified behavior in .github/workflows/dependabot-automerge.yml: Adds a changed-file scope check: when no files are changed or any changed path is outside web/, the step exits without setting ok=true; otherwise it sets that output.
observed — Modified behavior in .github/workflows/dependabot-automerge.yml: Adds approval and squash auto-merge for PRs whose scope check passed and whose metadata identifies an npm_and_yarn update that is not a major semver update. Approval is skipped when the review decision is already APPROVED; auto-merge is enabled only when no auto-merge request exists.

Full details: Title check

Explanation

The title "ci: auto-merge safe Dependabot updates for the website" matches the main change. The PR adds a workflow that approves and squash auto-merges Dependabot npm patch and minor updates under /web, and the title names that scope. It uses the conventional commit prefix "ci:", which fits the CI workflow changes. It is concise and specific, and it does not list files.

Full details: Description check

Explanation

The description follows the template structure and fills most required parts. It has a What section with a clear one-line summary and a Closes #85 reference. The Type section ticks chore. The Money path section is left unticked, which is correct for this change. The AI assistance section names the tool and records a human review. The checklist is mostly complete. The Notes section explains the re-land of #86, the three fixes, the required status check change, and how to verify. Two items are not ticked: the CLA item is unticked, and the Simulator and UI items are marked n/a but left unticked. The template's 'Money path' and 'CLA' items are not addressed in the description, but the core content is complete.

Full details: Out of Scope Changes check

Explanation

The new Dependabot workflow, the web-test trigger and job-name changes, the Dependabot deploy guard, and the CODEOWNERS entries all support #85. The changes do not show an unrelated product or dependency change.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 0 files. (3 skipped: 3 unsupported.)

Full details: Linked Issues check

Explanation

The changes address #85 by adding the Dependabot workflow, restricting the ecosystem and path scope, excluding major updates, and running web-test and CodeQL on every pull request. However, both gh pr view "$PR" calls use only a PR number. The workflow does not check out the repository and does not pass --repo or set GH_REPO. GitHub CLI therefore cannot reliably resolve the repository, so the scope check and the approval step can fail before automation occurs. The branch-protection setting described in the PR is a repository setting, not a coding change, and is not assessed as a coding defect.

Resolution

Pass the repository explicitly to each GitHub CLI call, for example with --repo "$GITHUB_REPOSITORY", or set an equivalent repository context. Add or update automated coverage for the workflow path before approval and auto-merge can run.

Major · Stability & Availability · Quick win

Set the repository context before calling gh.

This job does not check out the repository, and gh pr view "$PR" has neither GH_REPO nor --repo. GitHub CLI cannot resolve a PR number from the empty workspace, so the scope step fails before approval or auto-merge. Set GH_REPO: ${{ github.repository }} at job level so every gh call uses the intended repository. (cli.github.com)

Minor · Functional Correctness · Quick win

Use the pull-request author for the Dependabot exclusion.

github.actor identifies the user who triggered the workflow, not the pull-request author. If a human reopens or updates a Dependabot pull request, this condition can pass and run deploy for that Dependabot-authored pull request. Check github.event.pull_request.user.login instead. (docs.github.com)
