• Include a space after poe in the default message. For example: ('**Running poe ' + steps.resolve-command.outputs.command + '...**') to match the original formatting.

          > ${{ inputs.start-message || ('**Running `poe' + steps.resolve-command.outputs.command + '`...**') }}

• [nitpick] Consider using runs-on: ubuntu-latest or a supported specific runner (e.g., ubuntu-22.04) to ensure compatibility and automatic upgrades.

    runs-on: ubuntu-24.04
