# Print the latest Expo SDK major version.
#
# Usage: latest-sdk.sh
#
# The `expo` package's major version IS the SDK version (expo@56.x -> SDK 56).
# Uses bun to run `npm view expo dist-tags --json` (so it honors the local npm
# registry / proxy / auth config rather than hardcoding registry.npmjs.org),
# JSON.parse the result, and take the major via the `semver` package (falling
# back to a numeric split if semver can't be resolved). Run via the skill's
# `bash *expo-skill-eval/scripts/*` rule so SDK detection stays prompt-free —
# the npm child runs under bun, not as its own Bash tool call.
