Package Manager / Add

Install a package from the Unity Package Manager registry, Git URL, or local path. This operation modifies the project's manifest.json and triggers package resolution. Note: Package installation may trigger a domain reload. The result will be sent after the reload completes. Use 'package-search' tool to search for packages and 'package-list' to list installed packages.

packageId formats

• Plain package ID: com.unity.textmeshpro (installs latest compatible version).
• Pinned version: com.unity.textmeshpro@3.0.6.
• Git URL: https://github.com/user/repo.git.
• Git URL with branch/tag: https://github.com/user/repo.git#v1.0.0.
• Local path: file:../MyPackage.

Processing model

Returns Processing immediately with the supplied requestId. Once Client.Add completes, a follow-up result is delivered: success → SchedulePostDomainReloadNotification (delivers after the reload finishes), failure → an immediate error notification with the underlying Unity error message.
