Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install unreal-mass-entity-ecs

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent writes Mass Entity C++: processors, FMassEntityQuery queries, fragments and tags, archetypes, deferred commands, observers and entity spawning from configuration assets. It works from APIs checked against UE 5.8 and points to the thread-safety rules when they apply. You get code and a diagnosis suited to Mass.
