roborazzi

roborazzi is a skill for Claude Code, Codex from takahirom/roborazzi. It costs 95 tokens per session (912 once invoked), scanned A, original, Apache-2.0.

A screenshot-testing library for Android and JVM projects that captures app screens in ordinary JVM tests, without a physical device or emulator. It supports Android views, Jetpack Compose, Compose Previews, and Compose Multiplatform.

In plain words
What is it for?
Use it to configure Roborazzi, capture screenshots in tests, record baseline images, and compare or verify later screenshots.
Why use it?
It makes visual changes easier to catch by comparing new screenshots with saved baseline images. Running these checks as JVM tests can simplify and speed up the testing workflow.

About the project

Roborazzi is an Android testing tool that captures screenshots from JVM tests using Robolectric, which simulates Android framework behavior on a developer’s computer. It helps teams check an app’s visual appearance and interactions without relying solely on physical devices or emulators. The catalogue skill supports using Roborazzi for screenshot-based Android testing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

roborazzi scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Roborazzi

Roborazzi is a screenshot testing library for Android that runs on the JVM using Robolectric Native Graphics, so screenshot tests run as JVM unit tests without a device or emulator. It works with plain Android views, Jetpack Compose (including Compose Previews), and Compose Multiplatform.

The typical workflow: record baseline images with ./gradlew recordRoborazziDebug, then compare or verify against them with compareRoborazziDebug / verifyRoborazziDebug (task names vary by variant; see the build setup reference).
