I built a local GitHub Actions runner that pauses so you can shell into the failed step
Short summary
ciwalk is a new open-source tool that runs GitHub Actions workflows locally in Docker and can pause on failure or at breakpoints, dropping you into a shell in the same container environment. It targets the common pain point of insufficient CI logs when a shell step fails. Current limitations include no matrix support, secrets, or full expressions yet.
- •Runs GHA workflows locally in Docker with pause-on-failure capability
- •Drops into a shell with same env/cwd as the failed step
- •MVP with no matrix/secrets/full expressions support yet
