This skill lets Claude create and execute Playwright automation for page tests, multi-step flows, and browser validation instead of relying on fixed scripts. The browser is visible by default, common interactions have helpers, and a universal executor handles module resolution; it can be installed as a Claude Code plugin or standalone skill.

Swift Testing Agent Skill gives compatible AI coding tools focused guidance for Apple's modern Swift Testing framework. Its references cover test structure, expectations, asynchronous workflows, parameterized tests, traits and tags, parallel execution, isolation, and incremental migration from XCTest. Teams can use it during implementation or code review to identify migration opportunities and flaky patterns. It installs through the Agent Skills CLI, a Claude Code plugin, or manual copying, and functions as guidance rather than a standalone test runner.

@workersio/skills gives coding agents a risk-focused workflow for finding valuable test gaps, choosing an appropriate strategy, writing tests, generating replayable workloads, and reviewing existing cases. Its keep, redo, or remove gate asks whether a test would catch a failure that matters to users or operators rather than merely increasing coverage. It is packaged for Codex and Claude Code, while the Markdown-based workflow can be adapted to other skill-aware agents.

Litmus closes the gap between changing code and resolving a user’s problem. It drives the running application as the reporting user, follows the exact ticket steps, and inspects the live request and response, frontend state, and database. The tracker is updated only when the defect and its absence can be shown, so a green unit test, backend curl, or database row alone is not treated as proof.
