Enable automerge and automatic branch cleanup for automated PRs by Claude · Pull Request #56 · Stensel8/Scripts

Claude · 2026-03-29T12:49:08Z

Repository had automated dependency PRs created but required manual approval and merge despite owner approval. Branches accumulated after merge.

Changes

Automerge Workflow (.github/workflows/automerge.yml)

Auto-approves PRs from Claude, github-actions[bot], or branches matching automated-update/* and claude/*
Enables GitHub automerge via GraphQL API with squash merge
Requires all checks passing, skips drafts (e.g., NGINX PRs needing SHA256 verification)
Graceful error handling with PR comments on failure

Branch Cleanup Workflow (.github/workflows/auto-delete-branch.yml)

Deletes branches automatically after PR merge
Protects main, master, development, staging, production
Handles forks, non-existent branches, and closed-without-merge cases

Documentation (.github/AUTOMERGE.md, README.md)

Workflow behavior, eligibility criteria, security model
Manual trigger instructions, troubleshooting guide
Integration with existing auto-update-dependencies.yml flow

Integration Flow

check-dependencies.yml → creates issue
auto-update-dependencies.yml → creates PR
automerge.yml → approves + enables automerge ← NEW
GitHub → merges when checks pass
auto-delete-branch.yml → deletes branch ← NEW

Existing open PRs #54 and #55 will be processed once workflows activate.

+    types: [opened, ready_for_review, reopened]


This workflow only triggers on opened, reopened, and ready_for_review, but enabling automerge is gated on checks already being successful. If checks are still running at open time (common), should_enable_automerge becomes false and the workflow will never re-run when checks complete, so automerge never gets enabled. Consider enabling automerge regardless of current check state (GitHub will wait for required checks), and/or add triggers like pull_request: [synchronize] and check_suite: [completed]/workflow_run to retry.

+              body: '✅ Automatically approved by automerge workflow.\n\nThis PR was created by trusted automation and has passed all checks.'


The auto-approval review body claims the PR "has passed all checks", but this step runs whenever should_approve is true and does not verify check status. Either gate approval on checks passing or change the message to avoid stating something that may be false.

Suggested change

body: '✅ Automatically approved by automerge workflow.\n\nThis PR was created by trusted automation and has passed all checks.'

+permissions:
+  contents: write


This workflow posts a PR comment via github.rest.issues.createComment, but permissions only include contents: write. With explicit permissions, commenting will likely fail without issues: write (or pull-requests: write if you switch to a PR-specific API). Add the needed permission or remove the comment step.

+            // Check if it's a head branch from a fork
+            const isFork = context.payload.pull_request?.head.repo?.full_name !== context.payload.repository?.full_name;
+            if (isFork) {
+              console.log('Branch is from a fork, cannot delete from this repository');
+              return;
+            }


isFork is computed even when context.payload.pull_request is absent (workflow_dispatch). In that case the left side is undefined, so undefined !== <repo full_name> evaluates to true and the script returns early, meaning manual branch deletion will never work. Only perform the fork check when a PR payload exists (or set isFork to false for workflow_dispatch).

The relative links in "Related Documentation" point to ../workflows/..., which resolves to a non-existent top-level workflows/ directory from .github/AUTOMERGE.md. Update the links to the actual paths under .github/workflows/ (e.g., workflows/auto-update-dependencies.yml from this file, or .github/workflows/... from repo root).

+Dependabot PRs are also eligible for automerge if:
+- They pass all status checks
+- The workflow approves them automatically
+
+To disable automerge for Dependabot PRs, you can modify the eligibility check in `automerge.yml`.
+


Docs state Dependabot PRs are eligible for automerge, but the workflow eligibility check only allows Claude, github-actions[bot], or branch prefixes automated-update/ and claude/—it does not include dependabot[bot]. Either update the workflow to explicitly include Dependabot or adjust this documentation section to match current behavior.

Suggested change

Dependabot PRs are also eligible for automerge if:

- They pass all status checks

- The workflow approves them automatically

To disable automerge for Dependabot PRs, you can modify the eligibility check in `automerge.yml`.

Dependabot PRs follow the same eligibility rules as other PRs.

With the current configuration, Dependabot PRs are not treated as trusted automation for automerge by default.

To enable automerge for Dependabot PRs, you can modify the eligibility check in `automerge.yml` to include `dependabot[bot]` (for example, by treating it as a trusted author or by matching Dependabot-specific branch name patterns).

+### Permissions Required
+
+- `contents: write` - To enable automerge
+- `pull-requests: write` - To approve PRs and add comments


The "Permissions Required" section for the automerge workflow doesn’t mention the additional permissions needed for the current implementation (e.g., checks: read for checks.listForRef and issues: write for PR failure comments). After updating the workflow permissions, please update this section so operators can correctly configure least-privilege.

Suggested change

- `pull-requests: write` - To approve PRs and add comments

- `pull-requests: write` - To approve PRs

- `issues: write` - To post PR comments when automerge or checks fail

- `checks: read` - To read check statuses (via `checks.listForRef`) for eligibility

+### Permissions Required
+
+- `contents: write` - To delete branches
+


This workflow’s documentation says only contents: write is required, but the workflow also posts a PR comment via issues.createComment, which typically requires issues: write. Update the permissions section to reflect the actual required permissions (or remove the comment behavior).

Copilot · 2026-03-29T12:57:01Z

+
+permissions:
+  contents: write
+  pull-requests: write


Workflow uses github.rest.checks.listForRef and github.rest.issues.createComment, but the declared permissions only include contents: write and pull-requests: write. With explicit permissions, the token likely lacks checks: read and issues: write, causing 403s when listing check runs or posting the failure comment. Add the minimum required permissions (e.g., checks: read and issues: write) or adjust the workflow to avoid these APIs.
