Frequently Asked Questions About San-Hsien

FAQPage Schema
What tasks can I accomplish with San-Hsien's skills?

The 25 skills cover the full delivery lifecycle: spec drafting, task breakdown, test-driven development, root-cause debugging, multi-axis code review, OWASP security hardening, performance optimization, observability instrumentation, CI/CD setup, git versioning, and production launch checklists with rollback strategy.

Who are these skills designed for?

Software engineers and coding agents who want disciplined, verifiable development practices. They suit developers handling ambiguous requirements, high-stakes changes like production auth or irreversible migrations, and teams needing enforced quality bars, accessibility standards, and documented architecture decisions.

How do the skills get invoked in practice?

The using-agent-skills meta-skill governs discovery and invocation at session start, matching each piece of work to the right skill. Trigger phrases like 'ideate', 'stress-test my plan', or 'interview me' activate specific skills; browser-testing-with-devtools additionally requires the chrome-devtools MCP server configured.

Are San-Hsien's skills free and open source?

Yes. The organization profile describes personal and open-source projects with a local-first, verifiable focus across 52 public repositories. The skills are published openly in the registry with no indicated licensing fees or commercial tiers.

What prerequisites or dependencies do these skills require?

Most skills are methodology-driven and need no external dependencies. The exception is browser-testing-with-devtools, which requires the chrome-devtools MCP server to be configured for DOM inspection, console error capture, network analysis, and performance profiling in real browsers.
