Package Skills
Manage installed Unity packages and package-related helper flows such as Cinemachine and Splines setup.
Guardrails
Operating Mode (v1.9 three-tier):
- Approval (default): query skills (
package_list, package_check, package_search, package_get_dependencies, package_get_versions, package_get_cinemachine_status) run directly. Mutators (package_install, package_remove, package_install_cinemachine, package_install_splines, package_refresh) are FullAuto — on MODE_RESTRICTED, run the grant protocol.
- Auto / Bypass: SemiAuto and FullAuto run directly.
- Auto-forbidden in this module:
package_install and package_remove (MayTriggerReload = true, RiskLevel = "high"; package_remove also carries SkillOperation.Delete). They are reachable only under Bypass mode or via a user-managed Allowlist entry; the grant flow returns MODE_FORBIDDEN.
- Install/remove/refresh jobs return immediately with a
jobId; the actual package import + Domain Reload happens asynchronously and may make the REST server transiently unavailable. Poll with job_status / job_wait.
DO NOT (common hallucinations):
package_add / package_update do not exist -> use package_installpackage_get_info does not exist -> use package_list, package_check, package_get_dependencies, or package_get_versionspackage_search searches the installed package cache only; it does not query the Unity Registry- Package query skills initialize their cache automatically after Domain Reload. During the short cold-start window they return
{ success: false, status: "refreshing", cacheReady: false, retryStrategy: "wait_and_retry", retryAfterSeconds: 2 }; retry instead of treating this as installed=false.
- Package install/remove/refresh jobs can trigger package import and Domain Reload; expect transient server unavailability and use returned job IDs
Routing:
- For Cinemachine quick setup -> use
package_install_cinemachine
- For Splines quick setup -> use
package_install_splines
- For project manifest inspection -> use
project_get_packages
- For define symbol changes after package installation -> use
debug_set_defines
