 For example, you can have your normal automations that help developers with their PRs and a separate automation that automates Dependabot or Renovate version bumps. Both automations serve distinctly different purposes: the first helps your developers streamline their PRs, while the other reduces developers' toil by auto-approving version bumps. You will not want to unnecessarily trigger gitStream for Dependabot or Renovate, so you can configure the triggers to exclude the branch where Dependabot or Renovate PRs are created.

+#### `checkDependabot`

+Extract version bump information from Dependabot PRs description. This filter parses Dependabot PR descriptions to identify version changes and returns an array containing the "to" and "from" versions.

+| Argument | Usage  | Type   | Description                                                         |

+#### `checkSemver`
+
+Compare two software version numbers and determine the type of version change. This filter takes an array of two version strings and returns the type of change between them.

 #### `codeExperts`
 
 When requesting a review for a pull request, it's important to select a reviewer who has a deep understanding of the relevant code area, the domain problem, and the framework being used. This ensures that the reviewer can provide specific and informed feedback, rather than general comments that may not take into account the context in which the issue was solved.

     Use the [`config.git_history_since`](./cm-file.md#configgit_history_since) configuration to limit the git history analysis to commits after a specific date. This is useful for team transitions or when you want to focus on recent contributors only.
