🔗 GitHub Actions manual trigger CLI

Automating deployments across microservices or triggering remote CI/CD pipelines often requires firing off GitHub Actions workflows from outside the GitHub web interface. While GitHub provides the workflow_dispatch event for manual triggers, developers and DevOps engineers often rely on ad-hoc curl commands or manual browser clicks. This approach is prone to syntax errors, lacks validation, and makes it difficult to pass complex parameters or monitor run progress programmatically.

This script solves the problem by providing a production-ready command-line interface (CLI) to trigger GitHub Actions manual workflows (workflow_dispatch). It handles authentication, parses structured inputs, validates responses, and can optionally poll the newly created workflow run until completion—making it suitable for standalone developer usage, deployment scripts, or cross-repository orchestration.
