I built a local GitHub Actions runner that pauses so you can shell into the failed step

Problem I kept hitting: a step fails in CI, logs aren't enough, and "act" still feels all-or-nothing.

ciwalk runs GHA workflows locally in Docker and can pause on failure (or at a breakpoint). You drop into a shell in the same container — same env/cwd as the step — fix or inspect, then retry/continue/abort.

Install: uv tool install ciwalk / pip install ciwalk
Demo: https://github.com/kiwi-07/ciwalk (GIF in README)

Honest MVP limits: no matrix/secrets/full expressions yet. Built for the "why did this shell step fail?" cases.

If you try it on a real workflow that breaks, I'd love the issue report.
