Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Share Extension
SHARE EXTENSION: SETUP: Requires separate extension target (kind: "share" in plan extensions array). The extension receives shared content (URLs, text, images) from other apps via the share sheet.
PRINCIPAL CLASS (in extension target): class ShareViewController: SLComposeServiceViewController { override func isContentValid() -> Bool { return contentText.count > 0 // Validate before enabling Post button }
override func didSelectPost() { // Access shared items guard let item = extensionContext?.inputItems.first as? NSExtensionItem, let provider = item.attachments?.first else { extensionContext?.completeRequest(returningItems: [], completionHandler: nil) return }
if provider.hasItemConformingToTypeIdentifier("public.url") { provider.loadItem(forTypeIdentifier: "public.url") { [weak self] url, _ in // Handle URL self?.extensionContext?.completeRequest(returningItems: [], completionHandler: nil) } } }
override func configurationItems() -> [Any]! { return [] // Return SLComposeSheetConfigurationItem array for optional UI } }
INFO.PLIST KEYS (in extension's Info.plist via XcodeGen): NSExtensionPrincipalClass: $(PRODUCTMODULENAME).ShareViewController NSExtensionActivationRule: NSExtensionActivationSupportsWebURLWithMaxCount: 1 NSExtensionActivationSupportsText: true
APP GROUP: Use AppGroup entitlement to share data between main app and extension.
