The source file is a template with placeholder content, so there's no actual Peach integration here yet. What you're looking at is the Membrane boilerplate for building API integrations through their CLI, with auth handling and action discovery baked in. The official docs link points to Helpshift's iOS SDK for Peach, which is a customer support platform, but none of that functionality is actually wired up in this skill. If you need to work with Peach data, you'd be starting from scratch using the Membrane framework shown here. The structure mentions projects, documents, pages, and templates, but without implementation details or available actions.
