Build a new Synapse App as an OCI image and publish it to the Datamaker registry so the workspace can install it via the App Store. Use when the user asks to create/scaffold a Synapse App, sub-app, plugin, iframe app, or embedded dashboard, or mentions synapse-app.yaml, /plugins registry, apiVersion synapse.datamaker.io/v1, or the iframe bridge. Supports React, Vue, Next.js, Nuxt 3, Gradio, Streamlit, Static HTML, Django, FastAPI (priority in that order).

From the source SKILL.md

A Synapse App is a containerized HTTP app the host loads in an iframe. The platform discovers it by pulling an OCI image whose config carries a io.synapse.app.manifest label - the full synapse-app.yaml encoded as base64 YAML. There is no sub-apps/ directory anymore. There is no compose-file rewrite. Apps live in the registry; the workspace pulls and runs them.
