ci: retrigger automerge for open release PRs on push to main#449
Merged
Conversation
When main advances without a new commit landing on the release-please PR branch, no synchronize event fires and the automerge never re-evaluates. This workflow dispatches the automerge for every open release-please PR after each push to main, closing that gap. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Problem
When
mainadvances (e.g. a feature PR merges) without a new commit landing onthe release-please PR branch, no
synchronizeevent fires and the automergenever re-evaluates. The release PR can be left unmergeable or simply stale until
someone manually dispatches the automerge.
Fix
New workflow
release-please-automerge-retrigger.ymltriggers on every push tomain, finds all open release-please PRs, andworkflow_dispatches theautomerge for each one. The automerge itself is idempotent (it skips if already
merged, not a release branch, version unchanged, etc.), so dispatching it
multiple times is safe.
