Asserting Bounds And Dimensions

Q: What is a Claude Code skill and how does the Asserting Bounds And Dimensions skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Asserting Bounds And Dimensions is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.

Use this skill to verify Compose layout measurements from a UI test using `assertWidthIsEqualTo`, `assertHeightIsEqualTo`, `assertWidthIsAtLeast`, `assertHeightIsAtLeast`, `assertTouchWidthIsEqualTo`, `assertTouchHeightIsEqualTo`, `assertPositionInRootIsEqualTo`, `assertTopPositionInRootIsEqualTo`, `assertLeftPositionInRootIsEqualTo`, plus read helpers `getUnclippedBoundsInRoot`, `getBoundsInRoot`, `getAlignmentLinePosition`, `getFirstLinkBounds`, and the underlying `Dp.assertIsEqualTo(expected, subject, tolerance = Dp(.5f))`. Covers the half-dp default tolerance, the unclipped vs clipped distinction, the canonical "compute padding from two unclipped rects" pattern, and minimum-touch-target assertions like `assertHeightIsAtLeast(MinHeight + 1.dp)`. Use when the developer wants to assert sizes, padding, alignment, position in dp, or asks about `getUnclippedBoundsInRoot`, `DpRect`, touch-target size, or compares widths in pixels. If the developer is comparing layout dimensions from a test, use this skill.

From the source SKILL.md

Layout assertions belong in dp, run with a half-dp tolerance, and most of the interesting checks (padding, gap, alignment) are subtractions between two getUnclippedBoundsInRoot() rectangles. This skill picks the right size/position assertion, explains clipped vs unclipped, and shows the canonical "compute padding from two rects" pattern lifted directly from material3/ButtonTest.kt.

What this skill does

Asserting Bounds And Dimensions is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/asserting-bounds-and-dimensions/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the developer wants to assert sizes, padding, alignment, position in dp, or asks about `getUnclippedBoundsInRoot`, `DpRect`, touch-target size, or compares widths in pixels. If the developer is comparing layout dimensions from a test, use this skill.

Who uses this skill

The Asserting Bounds And Dimensions Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 93,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
