Playwright Skill

Analyzes DevOps Center test failures and Code Analyzer violations in plain language — failure category, offending file/class/method/line, rule violated, fix direction, and prioritized improvement suggestions (test-code vs production-code) — then optionally creates a tracked fix WorkItem on explicit request. Analysis is pure reasoning; work-item creation is a confirmation-gated write. Use this skill to explain failures or improvement suggestions, translate Code Analyzer violations, or track a fix as a work item. TRIGGER when: a run failed and the user wants root cause; a quality gate failure needs explaining; violations need translating; the user shares a failure payload and asks how to address it; wants to strengthen tests; or wants to create a fix work item, log a remediation, or assign a failure. DO NOT TRIGGER when: the user wants fix code written (use platform-apex-generate) or new test classes authored (use platform-apex-test-generate).

Explains how to develop Playwright - add APIs, MCP tools, CLI commands, and vendor dependencies.

Configures mewt or muton mutation testing campaigns — scopes targets, tunes timeouts, and optimizes long-running runs. Use when the user mentions mewt, muton, mutation testing, or wants to configure or optimize a mutation testing campaign.

Design and evaluate paid-ad experiments with hypotheses, randomization units, sample-size and duration assumptions, guardrails, platform experiment tools, analysis, and decision rules. Use for A/B test, split test, experiment design, hypothesis, statistical significance, sample size, test duration, or experiment readout.

Automates the end-to-end detection engineering workflow in Google SecOps using MCP tools. Use when fetching threat intelligence from blogs, generating Threat Detection Opportunities (TDOs), simulating attacker behavior with synthetic UDM events, evaluating rule coverage, generating new YARA-L 2.0 rules to close coverage gaps, and with user approval, deploy them to SecOps. Don't use when asked to perform threat hunting actions, and SOC investigative actions.

When the user wants to A/B test App Store product page elements to improve conversion rate. Also use when the user mentions "A/B test", "product page optimization", "test my screenshots", "test my icon", "conversion rate optimization", "CPP", or "custom product pages". For screenshot design, see screenshot-optimization. For metadata optimization, see metadata-optimization.
