How does this skill decide if a workflow is eligible?

It calculates if the average runtime plus two standard deviations is under 7 minutes and scans for incompatible patterns like Docker usage, services, or heavy compilation.

It is a lightweight, single-CPU GitHub-hosted runner with 5GB RAM and a 15-minute timeout, optimized for short, low-resource tasks like linting or notifications.

Does ubuntu-slim support Docker?

No, ubuntu-slim is a container-based runner and does not support Docker commands (build/push), Docker services, or custom container images.

What happens if a migration fails during runtime?

Since ubuntu-slim has fewer preinstalled tools, a job might fail if a specific dependency is missing. The skill recommends migrating non-critical tasks first to verify tool availability.

Optimizes GitHub Actions workflows by migrating eligible jobs to cost-efficient ubuntu-slim runners based on performance analysis.

This skill automates the migration of GitHub Actions workflows to the ubuntu-slim runner to optimize resource usage and reduce costs. It performs a comprehensive two-phase analysis: evaluating runtime statistics to ensure jobs fit within the 15-minute timeout and scanning YAML patterns for compatibility issues like Docker dependencies or high-resource requirements. Once analyzed, it generates a detailed migration plan, applies changes to YAML files, and prepares a Git diff for final user review, ensuring a safe and efficient CI/CD optimization process.
