Documentation — install, VS Code Marketplace, and one-page-per-product reference for each data extension.

Render @Preview composables to PNG outside Android Studio, so AI coding agents can see what they're changing. Works with Jetpack Compose (Android, via Robolectric) and Compose Multiplatform Desktop (via ImageComposeScene).

Renders include paused-clock animation captures (GIF or single frame) and opt-in ATF accessibility checks with annotated overlays.

Also renders Android XML resources — vector drawables, adaptive launcher icons, animated-vector drawables — and indexes the icon attributes in AndroidManifest.xml so tooling can link manifest lines to the same rendered PNG. Modules without any matching resources self-no-op, so this comes along for free with the plugin.

The agent loop

These tools give AI coding agents a tight, token-frugal feedback loop over Compose UI — the way Playwright gave web agents one over the DOM: act by a stable reference, observe structure rather than pixels, and turn exploration into durable tests. The capabilities below are exposed by the preview daemon's MCP server (and, where noted, the compose-preview CLI); see docs/daemon/MCP.md for the full tool surface.

• Target by semantic ref, not pixels. interactive/input and record_preview accept a target (testTag / role+text / a stable node ref) that the daemon resolves to the node's centre, so a click survives layout changes instead of breaking on a coordinate. Works on Android (Robolectric) a
