About this blueprint
AI
This blueprint automates weekly engineering status reporting by analyzing Git commit activity and generating a concise, human-readable summary using AI, then delivering it directly to Slack.
It performs the following actions every week:
- Clones a Git repository and checks out the selected branch
- Retrieves all commits from the last 7 days
- Uses an AI model to transform raw commit messages into a clear weekly development update
- Sends the resulting summary to a Slack channel on a fixed schedule
This pattern is designed for engineering teams, technical leads, and product stakeholders who want reliable visibility into development progress without manually writing weekly reports.
Configuration:
- Set the target Git repository and branch using the
repositoryandbranchinputs. - Add an OpenAI API key as a secret (
OPENAI_API_KEY) to enable AI summarization. - Configure a Slack incoming webhook URL to receive weekly updates.
- For private repositories, provide Git credentials (such as a GitHub Personal Access Token) via secrets.
- Adjust the CRON expression to control when the weekly summary is generated and sent.
The automation works with both public and private repositories and can be adapted to different schedules, branches, or notification channels. By automating weekly Git summaries, teams reduce reporting overhead while maintaining consistent, high-quality communication.
