Search Android (Jetpack/androidx/Compose) and Apple (SwiftUI/UIKit) docs.

Args: query: what you're looking for, e.g. "animate lazy list item". platform: "android" | "apple" | "" for both. target_version: version the project targets (e.g. "1.6.0" for androidx, "16.0" for iOS). Results the target can't use are filtered out unless include_unavailable is true, and each hit is annotated with its availability status for that version. include_unavailable: keep results not yet available at target_version. limit: max results.

Full reference card for a symbol: signature, summary, availability, and any deprecation/migration pointer. Use exact names ("NavigationStack", "animateItem") for best results.

Anti-hallucination check. Confirms whether an API is real AND usable on a specific version before an agent writes code against it.

Args: name: symbol name, e.g. "scrollTargetBehavior" or "animateItem". target_version: the version to check against ("17.0", "1.6.0", "34"). platform: "android" | "apple" | "" to search both.

Returns a verdict: available / deprecated / not-yet-available / unknown, with the migration target when relevant.

Show the availability timeline (since / deprecated / removed) for a symbol and its migration lineage.

Retrieve release-note chunks describing what changed. Good for "what's new in Compose 1.7" or "SwiftUI iOS 17 changes".
