Use this skill to build precise Compose UI test queries by composing SemanticsMatcher predicates with infix and, infix or, and operator not, plus the prebuilt filter library (hasText, hasClickAction, isEnabled, isOn, hasTestTag, hasContentDescription, hasParent, hasAnyAncestor, hasAnyChild, hasAnySibling, hasAnyDescendant, hasImeAction, hasScrollToKeyAction, hasScrollToNodeAction, isDialog, isPopup, isRoot, isFocused, isEditable, isHeading). Covers SemanticsMatcher.expectValue / keyIsDefined / keyNotDefined for custom semantics keys. Use when the developer asks how to find "an enabled button with text Submit", how to combine matchers, how to filter by a custom SemanticsPropertyKey, how to write a hierarchical predicate, or mentions hasParent, hasAnyAncestor, expectValue. If the developer wants one matcher instead of three chained assertions, use this skill.

Quick start
Copy the install prompt. Use the green button above this README.
Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
Use this skill to build precise Compose UI test queries by composing `SemanticsMatcher` predicates with `infix and`, `infix or`, and `operator not`, plus the prebuilt filter library (`hasText`, `hasClickAction`, `isEnabled`, `isOn`, `hasTestTag`, `hasContentDescription`, `hasParent`, `hasAnyAncestor`, `hasAnyChild`, `hasAnySibling`, `hasAnyDescendant`, `hasImeAction`, `hasScrollToKeyAction`, `hasScrollToNodeAction`, `isDialog`, `isPopup`, `isRoot`, `isFocused`, `isEditable`, `isHeading`). Covers `SemanticsMatcher.expectValue` / `keyIsDefined` / `keyNotDefined` for custom semantics keys. Use when the developer asks how to find "an enabled button with text Submit", how to combine matchers, how to filter by a custom `SemanticsPropertyKey`, how to write a hierarchical predicate, or mentions `hasParent`, `hasAnyAncestor`, `expectValue`. If the developer wants one matcher instead of three chained assertions, use this skill.
