update-kit-dry-run

/update-kit-dry-run - Preview Update Changes

Preview what /update-kit would change without actually deploying.

Instructions

Run the following block as one Bash invocation. It uses the same strict, non-evaluating manifest/config lookup as /update-kit: a current non-MDM manifest binds the checkout to the exact config used at install time, while a legacy or MDM manifest uses ~/.claude-starter-kit.conf. A legacy config with no KIT_REPO key falls back to ~/.claude-starter-kit. An invalid explicit binding, key, or repository stops the preview instead of silently using another path.
