How do I make my act settings permanent?

You can create a .actrc file in your project root to store persistent flags like platform mappings (-P), resource limits, and architecture settings.

How can I fix permission issues in act containers?

The skill provides patterns for mapping host user IDs to the container using --container-options to prevent workspace permission errors.

What runner images are recommended for act?

The skill suggests catthehacker/ubuntu images for general use, node:alpine for lightweight workflows, and full-latest images when maximum tool compatibility is required.

Does this skill help with Apple Silicon Mac compatibility?

Yes, it provides specific commands for setting the --container-architecture to linux/arm64 to ensure Docker containers run correctly on M1/M2/M3 chips.
