SKILL.md packages that extend Claude Code, Cursor, Copilot, and other AI agents.
Tags

mutant
Run Mutant mutation testing, analyze alive mutations, and produce clear fix actions (add tests or simplify code).

skills_collection
Industry-standard Jest testing setup for TypeScript projects with guidance for React Testing Library, ts-jest, snapshots, and coverage configuration.

claude-code-python-stack
Guides and best-practice patterns for Python testing using pytest, TDD, fixtures, mocking, parametrization and coverage goals.

openclaw-medical-skills
Extract per-cytosine methylation calls (CpG/CHG/CHH) from Bismark-aligned BAMs and produce bedGraph/coverage reports for downstream analysis.

claude-skill-registry
Run and manage Python test suites with pytest — discover tests, run with coverage or parallelism, and produce failure analysis and checkpoints.

dotfiles
Enforces a TDD workflow for development: write tests first, aim for 80%+ coverage across unit, integration, and E2E tests, and follow a repeatable RED-GREEN-REF

skillshub
QA orchestration skill: defines test strategy, assigns unit/integration/E2E suites, enforces coverage thresholds, and coordinates CI test execution.

crap4clj
Compute CRAP scores (cyclomatic complexity combined with coverage) for Clojure functions to flag high-risk, under-tested code.

claude-plugins
Quick reference for writing Python tests with pytest: fixtures, parametrization, coverage, mocking, and async testing.

claude-skill-registry
Structured guidance for test strategy, safe execution, and coverage analysis for agent workflows; includes commands, isolation rules, and a review checklist.

ai-playground
Scans a repository, discovers and runs tests, computes coverage, evaluates test quality, and generates a metrics report website and JSON output.

claude-skill-registry
Run and manage Python test suites with pytest — discover tests, execute with coverage or parallelism, and produce failure analysis and checkpoints.

ucai
Guidance and templates for designing tests, scaffolding unit/integration/E2E tests, and improving test quality and coverage across languages and frameworks.

insurance-skills
Generates clinical insurance/coverage resources modeling payer types (Medicare, Medicaid, commercial, VA, Tricare) and coverage periods for FHIR-style resources

claude-skill-registry
Guidance for designing, running, and analyzing test suites for agents: test isolation, execution patterns, and coverage-based enforcement.
