Is this skill customizable for different project structures?

Yes, while it provides a standard mapping for JS/TS projects, it sets a pattern for Claude to identify the most meaningful verification path for any architecture.

Can this skill handle database-specific security checks?

Yes, it includes logic for selecting specialized Row Level Security (RLS) diagnostic scripts when authentication or data access rules are modified.

Does it work with standard npm scripts?

Absolutely. It is designed to work with common project scripts like npm run lint, npm run typecheck, and npm test.

How does this skill improve development speed?

It prevents running slow, unnecessary test suites by identifying the specific, smallest command needed to verify a localized change, like using typecheck instead of a full build.

When should I use E2E tests according to this skill?

The skill recommends running E2E tests specifically when changes affect user interface flows, navigation, or routing to ensure a stable user experience.

Security & Testing

Optimizes development cycles by selecting the most efficient verification commands based on specific code changes.

The Smart Test Selection skill enhances Claude's ability to maintain high code quality without sacrificing speed. By mapping specific types of changes—such as TypeScript definitions, UI routing, or database security policies—to their most relevant validation scripts, the skill ensures that only necessary checks are run. This prevents the execution of bloated test suites for minor changes, providing developers with rapid feedback through targeted commands like type-checking, linting, or specialized Row Level Security (RLS) diagnostics.
