Watching a repository on GitHub tells you about social activity (e.g. PRs, issues, etc.), but it doesn't notify you about file-level changes that you and your team might care about.

For example, when an external vendor merges in their work, or when a critical part of the codebase is changed, or when new dependencies are added, etc

Commit Hawk Action fills that gap.

Install the Incoming Slack Webhook app to your Slack workspace. Reference that webhook URL in slack_webhook_url param in your action's yml as shown below.

Actions can be setup to run conditionally when a specific file(s) on a particular branch are changed.

The paths keywords accept glob patterns that use the * and ** wildcard characters to match more than one path name. For more information, see the documentation.
