The Glean GitHub action allows you to create agents that perform key GitHub operations. This integration connects company knowledge and operational tasks, bringing AI-powered review, documentation, and workflow automation into the developer experience. You can use GitHub actions to do the following:
  • Create a PR
  • Create a branch
  • Edit code
  • Read a file from a branch
  • Fetch logs for a workflow
  • Find a diff for a PR

​
Usage examples

Using these GitHub actions, you can automate numerous tasks, such as:
  • Creating a pull request with a well-summarized, automatically generated description to streamline code reviews.
  • Creating a new feature branch directly from a conversation or workflow, reducing manual setup.
  • Editing code files based on AI-suggested changes without directly interacting with the GitHub UI.
  • Reading files from a specific branch to check implementation details or review changes in context.
  • Fetching workflow logs to debug CI failures or deployment issues quickly via chat.
  • Finding the diff for a pull request to understand exactly what changes have been made before merging.

​
Configuration

Prerequisites

  • A GitHub App must be created for the organization, with appropriate app and webhook/authorization URLs (handled by Glean or as guided by the setup documents).
  • The GitHub App must be installed and connected to Glean, often requiring a GitHub Copilot subscription to surface features in the IDE or web UI.
