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.
