Description
Hi, HN!I've been running GitHub Actions workflows for a while, and when GitHub announced ubuntu-slim runners as a cheaper alternative to ubuntu-latest, I wanted to migrate. (Blog: https://github.blog/changelog/2025-10-28-1-vcpu-linux-runner...)But manually checking which workflows can safely migrate is tedious—you need to check for Docker usage, services, containers, execution times, and missing commands.So I built gh-slimify, a GitHub CLI extension that automates this. It scans your workflows, detects migration candidates, checks for incompatible patterns, identifies missing commands, and can safely update workflows with one command.Try it: gh extension install fchimpan/gh-slimify gh slimfy # Scan workflows gh slimfy fix # Update safe jobs onlyOpen source (MIT). I'd love feedback on how to improve it or what edge cases I might have missed.

Could you build this?
Yes This is a utility script or CLI that parses GitHub Actions YAML workflow files, checks CPU/RAM utilization logs via GitHub API, and suggests runner changes.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
