Summary

Reports workflows that are likely to benefit from a concurrency group.

Why It Matters

Without concurrency, repeated pushes to the same branch can leave obsolete runs consuming runner minutes. This is especially noisy for pull requests and active feature branches.

Recommendation

Add a workflow-level concurrency group when cancellation is safe:

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true

Use caution for deployment workflows where canceling an in-progress run may be unsafe.
