Testing Claude Skills
3 543 testing skills from 425 authors. They run test suites, check accessibility and catch what broke. Half of them fit into 1 799 tokens or less — that is what one costs your context window when the agent loads it. 404 ship runnable scripts rather than instructions alone. 2 of them cannot work without an MCP server, most often rube. We also found 429 copies of these same skills sitting in other people's repositories — counted once here, not 429 times.

>- Add Dynamic Application Security Testing (DAST) steps to existing Harness pipelines using Harness STO scanners. Supports API DAST / Traceable (default), Burp Suite Enterprise, ZAP (OWASP), Nikto, and Nmap. Scans running application instances for vulnerabilities including API security issues, injection flaws, misconfigurations, and exposed services. Can insert the scan step into an existing CI or SecurityTests stage or create a dedicated SecurityTests stage. Use when asked to add DAST scanning, configure dynamic application testing, set up API security scanning, scan a running application, or add runtime security testing to a pipeline. scan running app, add Burp Suite scan, add ZAP scan, add Nikto scan, runtime security scan, API security scan.
>- Optimize Harness CI/CD pipeline performance via MCP. Configure parallel test execution with Test Intelligence, design multi-layer caching strategies, analyze pipeline bottlenecks with stage-level timing breakdowns, optimize cache hit rates, and design monorepo CI pipelines with selective builds. Use when asked to speed up pipelines, improve cache hit rates, set up parallel testing, optimize build times, or configure monorepo builds. Do NOT use for creating new pipelines (use create-pipeline instead) or debugging failures (use debug-pipeline instead). build optimization, caching strategy, monorepo pipeline, pipeline bottleneck, build speed.
Use when the user reports misbehaving software to investigate — a bug, crash, wrong output, flaky behavior, or '為什麼壞掉/不會動/查一下' — and the root cause is not yet established. Enforces building a red-capable reproduction command BEFORE any hypothesis is allowed, then 3-5 ranked falsifiable hypotheses before testing any single one. NOT for conceptual questions, code reading requests, or feature work. When a failing command already exists, Step 1 is pre-satisfied — still apply, jumping straight to the hypothesis discipline.
