ALWAYS use this skill when writing or refactoring code. Includes context-dependent sub-skills to empower different coding styles across languages and runtimes.

Use when invalid data causes failures deep in execution - validates at every layer data passes through to make bugs structurally impossible rather than temporarily fixed

Use when writing or refactoring code, before creating files - enforces separation of pure business logic (Functional Core) from side effects (Imperative Shell) using FCIS pattern with mandatory file classification

Use when searching for or transforming code patterns structurally - provides ast-grep CLI syntax, metavariable patterns, and language-specific examples for precise AST-based code search and rewriting

Use when writing database access code, creating schemas, or managing transactions with PostgreSQL - enforces transaction safety with TX_ naming, read-write separation, type safety for UUIDs/JSONB, and snake_case conventions to prevent data corruption and type errors

Use when searching markdown knowledge bases, documentation, or notes for relevant context - provides qmd CLI syntax for keyword, semantic, and hybrid search across indexed collections

Use when writing tests for serialization, validation, normalization, or pure functions - provides property catalog, pattern detection, and library reference for property-based testing

Use when writing documentation, guides, API references, or technical content for developers - enforces clarity, conciseness, and authenticity while avoiding AI writing patterns that signal inauthenticity

Use when writing or reviewing tests - covers test philosophy, condition-based waiting, mocking strategy, and test isolation
