Create or audit requirements-to-design-to-code-to-test traceability. Builds atraceability matrix (REQ → design/ADR → implementation files → tests →evidence) and flags gaps (unimplemented requirements, untested changes,undocumented decisions). Use when you need a requirements traceability checkfor a PR/release, regulated/compliance work, or when requirements are driftingfrom implementation.

Python development for scientific computing and SciTeX projects. Includes testing, debugging, ML practices, and environment management.

Custom Hypothesis strategy patterns for property-based testing. Activated when designing test data generators or property tests.

Guide for building applications with @fpkit/acss components. This skill should be used when composing custom React components from fpkit primitives, validating CSS variable naming conventions, extending fpkit components with custom behavior, or ensuring accessibility compliance in fpkit-based applications. Use when the user needs help with component composition patterns, CSS customization, or accessibility testing. Not for developing the @fpkit/acss library itself.

Ensure Python classes include appropriate, developer-friendly dunder methods—especially __repr__ and __str__. Use when: (1) Writing or modifying Python class definitions in .py files, (2) Refactoring existing Python classes, (3) Adding or improving __repr__, __str__, or natural arithmetic/comparison/container dunders. Do NOT use for: tests, fixtures, mocks, stubs, non-Python files (YAML, JSON, TOML), auto-generated code vendor libraries, or when user explicitly asks not to modify dunders. Ignored paths: tests/, *_test.py, test_*.py, .venv/, build/, dist/, migrations/, __init__.py.
