What problem does it solve? Releasing an XDRS extension package without verifying that consumers can actually install and run it leads to broken downstream workspaces. This Skill provides a repeatable procedure to pack the mydevkit package, validate it in a consumer fixture, and publish with confidence. ## Core Features & Use Cases - Package Packing: Runs pnpm install and pnpm pack to produce a distributable tarball in the dist directory. - Consumer Verification: Installs the packed tarball alongside the local xdrs-core tarball in a consumer fixture, then runs mydevkit install, mydevkit check, and xdrs-core lint against the generated output. - Guided Publishing: Bumps the package version based on consumer impact and publishes only after local verification passes. - Use Case: After updating the mydevkit extension that composes xdrs-core through a standalone .filedistrc file, follow this Skill to confirm the packed tarball installs cleanly in a consumer workspace before publishing a new version. ## Quick Start Pack the mydevkit package, verify it installs and passes checks in the consumer fixture, then bump the version and publish.
