Catalyst SDKs — initialization patterns, service access, and method reference for Node.js, Web (browser), Python, Java, Android, iOS, and Flutter. Trigger on 'SDK', 'zcatalyst-sdk-node', 'Node.js SDK', 'Web SDK', 'Python SDK', 'Java SDK', 'Android SDK', 'iOS SDK', 'Flutter SDK', or 'initialize SDK'.

How It Works 1. Identify the platform — Node.js, Web (browser), Python, Java, Android, iOS, or Flutter. 2. Load the matching reference file — Each platform has its own SDK reference with initialization pattern and service methods. 3. Initialization first — Always show the SDK init call before any service specific code. 4. Platform quirks — Web SDK uses browser auth (no service account); Node.js SDK uses server side init; Mobile SDKs require the Catalyst project ID in the config. Triggers Use this skill for: "SDK", zcatalyst sdk node , zcatalyst sdk , "Node.js SDK", "Web SDK", "Python SDK", "Java SDK", "Android SDK", "iOS SDK", "Flutter SDK", sdk web , sdk mobile , catalyst.initialize , catalystApp , "initialize SDK", or any platform specific SDK question.
