This is Lovstudio's paid Skill. During installation, only the encrypted distribution package is downloaded; after logging in and redeeming with Credits, it will be decrypted at runtime according to account entitlements.
npx lovstudio skills add wxmp-cracker
uvx lovstudio-skill-helper decrypt wxmp-cracker
The decrypted output is used only for the current Agent call, and the source code will not be written to the installation directory. When additional materials are needed, use the helper to decrypt the corresponding relative paths on demand.
