Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install observer-publish-subscribe

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 creates an observable object and its observers, then wires reactions to state changes. You get the code, a case study and the risks to watch for, such as forgotten subscriptions.
